Why Substance Abuse is the Biggest Safety Issue in Construction

It’s hard to talk about substance use on a construction site. When taking your eye off the ball for a second can cause a fatal accident, working while high puts everyone at risk.

When we talk about construction safety, it’s easy to stick to what we know: proper PPE, harnesses and lifelines, trench shields, etc. Every safety director on a job site reminds construction crews daily about the potential hazards they face.

However, when it comes to talking about arguably the biggest safety problem on any project – one that takes the lives of 131 out of every 100,000 construction workers – there is often silence.

Because it’s hard to talk about substance abuse and addiction in the middle of a hard-driving construction site. When you’re on the job, the schedule is everything; the pressure to just “suck it up” and perform is intense. And in an industry where taking your eye off the ball for a second can cause a fatal accident, working while high puts everyone at risk.

Josh Vitale, a construction supervisor with Hoffman Construction Company, one of the founders of the GUTS project/Tough Enough To Talk, and Vice Chair of Construction Suicide Prevention Week shared some sobering statistics:

Construction Workers:

  • Are seven times more likely to die of an opioid overdose than workers in other industries
  • Have the highest proportion of heroin-related overdose deaths
  • Represent about 25% of fatal opioid overdoses among all workers

The National Survey on Drug Use, administered by the Substance Abuse and Mental Health Administration, reports that construction workers deal with substance and alcohol disorders at nearly double the rate of any other industry. The national average for an “alcohol use disorder” is 7.5%; that rate skyrockets to 12% among construction workers, and they are 150% more likely to be diagnosed with a substance use disorder than other full-time workers.  

Construction workers are a statistically outsized group who struggle with substance use disorders, overdoses, and suicide.

Vitale shared harrowing stories of drug and alcohol-related accidents, injuries, and overdose deaths he’s dealt with personally on sites he has supervised.

“Construction requires workers to sacrifice their bodies for decades. It’s no wonder they’re self-medicating for chronic pain. It’s not uncommon to see multiple overdoses per project. It has become commonplace, and that fact is tragic.”

Construction Dive reported that at the micro level, the overdose rates were highest among roofers (177.4 per 100,000), drywall installers & tapers (175.1 per 100,000), and painters (162.1 per 100,000). The stressors that accompany construction work, seasonal employment, downtime between jobs, and the physical strain of performing the work are all contributing factors that lead to substance use and abuse.

And as part of a 2022 round table on mental health in construction, Cindy DePrater said, “Research shows when employers initiate and support treatment for mental health disorders and substance misuse, it is more effective in the long term than at the urging of family or friends. When we take care of ourselves, we feel safer. When we take care of ourselves, it also becomes easier to support others.”

Part of the issue with overdose and suicide deaths in construction is gender specific. Construction is still a heavily male industry, and the suicide rate for workers is four times higher than the general population, according to the U.S. Department of Labor. That may also play a part in why it is so difficult for construction workers to seek out help.

As DePrater pointed out, and Vitale agrees, one solution is to bring the help directly to those who need it. That is how the Get Us There Safely (GUTS) Project was born.

Hoffman Construction Company graphic: White and yellow on a black background, with the words “Depression is everywhere. So is help.” and the Tough Enough To Talk/GUTS logo.
Hoffman Construction Company is centering mental health and substance use issues
with the GUTS initiative.

GUTS’ goal is to provide a decompression space on site for construction workers. They’ve placed 10 trailers on jobsites throughout the U.S., and one in Israel, that contain private rooms for telehealth & teletherapy appointments, a lounge area to allow for a quiet moment, and some entertainment like foosball tables and dart boards. Vitale characterizes a GUTS trailer as having all the characteristics of a bar, without any of the damaging substances.

GUTS and Tough Enough To Talk aim to provide anyone in need a space to de-stress, breathe, and maybe to talk before making an unfortunate choice. And as anyone on a job site knows, getting a construction worker to open up about anything is a very tall order. That’s why Construction Safety Week (CSW) began to feature mental health and substance abuse materials to their safety talks in 2020 and have continued to center mental health and physical health concerns in this year’s theme – Value Every Voice.

Just like knowing the best practices to avoid slips, trips, and falls, your mental health and wellbeing are crucial to your ability to perform at your peak and stay safe. So let’s value every voice by listening, even when it’s tough to talk about it.

Construction Safety Week is May 10-14, 2024. GPRS offers complimentary CSW talks on job sites throughout the nation. Schedule yours today.

Uncovering the Veiled: The Intricacies of Locating Buried Utilities

When it comes to construction or excavation projects, you need to know what lies below. Professional utility locating services like those offered by GPRS can keep your project on time, on budget, and safe.

Beneath our feet lies a labyrinth of essential infrastructure, a network of buried utilities that powers our modern world.

From electrical cables to water pipes, these lifelines remain unseen, hidden from view, yet vital for our daily lives. However, when it comes to construction or excavation projects, ignorance of these underground assets can lead to costly damages, service disruptions, or even dangerous accidents.

The solution? A meticulous process of utility locating, employing advanced technologies and professional expertise to unveil the secrets hidden beneath the earth's surface.

A GPRS Project Manager runs a ground penetrating radar scanner across a job site.
When it comes to construction or excavation projects, you need to know what lies below. Professional utility locating services like those offered by GPRS can keep your project on time, on budget, and safe.

Federal law requires that before you dig you must call your state’s 811 one-call service to provide you with the approximate location of all buried public utilities on your job site.

But it’s important to remember that 811 contractors do not locate private utilities, which make up 60% of all buried infrastructure in the U.S. This means that to ensure you won’t hit anything when you break ground, you need to hire a private utility locating company in addition to contacting 811.

Understanding the Need for Utility Locating

Before delving into the intricacies of utility locating, it's crucial to grasp why it's indispensable.

Picture a construction crew breaking ground for a new building or a homeowner digging to plant trees in their backyard. Without prior knowledge of buried utilities, they run the risk of inadvertently severing power lines, puncturing water mains, or damaging telecommunication cables. Beyond the inconvenience and expense, such mishaps can pose serious safety hazards and lead to service outages.

A GPRS Project Manager holds an electromagnetic locator and a spray paint wand.
Utility locating specialists like GPRS’ SIM-certified Project Managers are equipped with the tools and expertise to mitigate the risk of subsurface damage on your job sites.

The Role of Professional Utility Locating Services

Enter the professionals: utility locating specialists equipped with the tools and expertise to mitigate these risks. A professional utility locating company offers a comprehensive array of services tailored to identify and map the underground infrastructure accurately. These services are not limited to public utilities but also extend to private facilities, such as underground storage tanks, septic systems, and irrigation lines.

Tools of the Trade: Ground Penetrating Radar and Electromagnetic Locating

At the heart of utility locating are two primary technologies: Ground penetrating radar (GPR) and electromagnetic (EM) locating. GPR works by emitting high-frequency radio waves into the ground and analyzing the reflected signals to detect subsurface anomalies. This non-destructive method is particularly effective for locating non-metallic utilities like plastic pipes and concrete structures.

A ground penetrating radar scanner provides real-time data, allowing technicians to visualize the underground environment accurately.

On the other hand, Electromagnetic locating relies on electromagnetic fields to identify buried metallic objects. By transmitting signals through a transmitter coil and detecting them with a receiver coil, technicians can pinpoint the location and depth of metallic utilities such as power lines and metallic pipes. While electromagnetic locating is proficient in detecting metallic objects, it may encounter challenges with non-conductive materials.

Integration of GPS for Precision Mapping

In conjunction with GPR and electromagnetic locating, Global Positioning System (GPS) technology plays a pivotal role in utility locating. GPS enables technicians to geo-reference the detected utilities accurately, creating detailed maps of underground assets. These maps serve as invaluable resources for construction planning, excavation projects, and infrastructure maintenance, enhancing efficiency and minimizing risks.

The Utility Locate Process: Methodical and Precise

The utility locate process follows a systematic approach, combining advanced technologies with meticulous fieldwork. It typically begins with thorough research, including reviewing existing utility records, as-built drawings, and historical documentation. This preliminary phase provides valuable insights into the location and type of buried utilities present in the area.

With a comprehensive understanding of the site's underground landscape, technicians deploy a combination of GPR and electromagnetic locating equipment to conduct on-site surveys. They traverse the area methodically, scanning the ground surface and marking the detected utilities with paint or flags. Throughout this process, GPS technology ensures the accurate recording of each utility's location and attributes.

Challenges and Limitations

While utility locating technologies have advanced significantly in recent years, challenges and limitations persist. Factors such as soil composition, depth of burial, and interference from nearby structures can impact the accuracy of detection. Additionally, non-metallic utilities pose a unique challenge, as they may not produce strong electromagnetic signals and can be more challenging to detect with GPR alone. Consequently, a multi-faceted approach that combines various technologies and field expertise is often necessary to overcome these obstacles.

GPRS Conducts Utility Locating Services on Private Property in Maine

GPRS recently provided private utility locating services to ensure safe trenching and excavation on a private residence in Maine.

GPRS recently provided utility locating services to ensure safe trenching and excavation at a private residence in Maine.

GPRS helps commercial construction, AEC, and facility management customers Intelligently Visualize The Built World® to mitigate subsurface damage and create existing condition documentation on commercial projects.

However, the general contractor for this project had worked with GPRS on several large-scale projects across the United States and contacted us to locate and map buried utilities on the quarter-acre private property after discovering that existing as-built documentation was out of date and likely inaccurate.

While federal law requires that you contact your state’s 811 one-call service prior to excavating to obtain the estimated location of all public utilities on your job site, it’s important to remember that 811 contractors do not locate private utilities – which make up roughly 60% of all subsurface infrastructure in the U.S.

GPRS utility locating services mitigate subsurface damage by telling you where it’s safe to dig.

To ensure that you are safe to dig, it’s vital to hire a professional private utility locating company like GPRS in addition to calling 811.

In Maine, Senior Project Manager Peter Kessinger utilized ground penetrating radar (GPR) and electromagnetic (EM) locating to locate and map all utilities on the property.

A GPRS Project Manager moves a ground penetrating radar scanner over grass.
Ground penetrating radar (GPR) is one of GPRS’ primary tools for conducting utility locates.

GPR scanners emit radio waves into the ground or a concrete slab, and those waves interact with any buried objects hidden within. The scanner detects these interactions and displays them in a readout as a series of hyperbolas that vary in size and shape depending on the type of material located. GPRS Project Managers are specially trained to interpret these readouts to tell you the precise location of the buried objects and provide their depth within the ground or concrete.

EM locators detect the electromagnetic signals radiating from metallic pipes and cables. These signals can emanate from current flow in a live electrical cable, or a conductive pipe acting as an antenna and re-radiating signals from stray electrical fields and communications transmissions. Your Project Manager can also create a signal by applying current to a known pipe, allowing them to map that utility’s path through your property.

GPRS Project Managers typically use both GPR scanners and EM locators when mapping underground utilities. The technologies compensate for each other’s limitations and create a redundant confirmation when designating subsurface elements – a key component of Subsurface Investigation Methodology (SIM), the industry-leading training program that we use to educate our field team members.

Kessinger located and annotated the depth of multiple previously unknown buried utilities, and he also identified the location and depth of an existing septic leach field on the property.

A septic leach field being installed on a property.
Septic leach fields are a vital component of a residence’s septic system. Damaging any part of this system during excavation or trenching could result in costly damage and even soil contamination.

Also known as a septic tank drain field or a leach drain, this component of a septic system acts as a disposal filter for organic material and consists of an underground system of perforated pipes adjacent to the septic tank. After contaminants and liquid waste have been broken down by bacteria in the tank, the material then flows into the leach field through underground pipes. As liquid travels through the leach field pipes, it will seep into the ground below and be naturally filtered by the soil.

Had the contractor struck a component of the leach field during excavation, they could have caused costly damage and contaminated the property’s soil with untreated wastewater. Fortunately, the accurate utility maps created using Kessinger’s field-verified data prevented this from happening.

All utilities on the property were marked with paint and flags on the ground so that the contractor had a visual guide to reference while excavating. Additionally, our PMs use a global positioning system (GPS) to collect data points of findings that are used to generate a plan, KMZ file, satellite overlay, or CAD file to permanently preserve results for future use.

Frequently Asked Questions

Can GPRS find PVC piping and other non-conductive utilities?

GPRS scanning is exceptionally effective at locating all types of subsurface materials. There are times when PVC pipes do not provide an adequate signal to ground penetrating radar equipment and can’t be properly located by traditional methods. However, GPRS Project Managers are expertly trained at multiple methods of utility locating and can easily find PVC.

Can GPR be used to verify known measurements?

We can use ground penetrating radar (GPR) to cross-check the measured depth and location of a buried utility with existing as-built plans to verify the accuracy of plans.

Is GPRS able to distinguish between each type of underground utility that’s located?

In most situations, we can identify the utility in question without any problems, although it is not always possible to determine what type of utility is present. When this happens, we attempt to trace the utility to a valve, meter, control box, or other signifying markers to determine the type of utility buried.

Department of Energy Announces Rule Designed to Expedite Transmission Permitting

The Biden-Harris Administration, through the Department of Energy (DOE) issued a final rule to establish the Coordinated Interagency Transmission Authorizations and Permits (CITAP) Program, which, according to an article on the DOE’s website, “aims to significantly improve Federal environmental reviews and permitting processes for qualifying transmission projects.”

In what’s being touted as a part of the federal government’s continued commitment to bolster the U.S. power grid, the Biden-Harris Administration has announced a final transmission permitting reform rule and a new commitment for up to $331 million aimed at adding more than 2,000 megawatts (MW) of additional grid capacity throughout the Western United States.

The administration, through the Department of Energy (DOE) issued a final rule to establish the Coordinated Interagency Transmission Authorizations and Permits (CITAP) Program, which, according to an article on the DOE’s website, “aims to significantly improve Federal environmental reviews and permitting processes for qualifying transmission projects.”

“Under the CITAP Program, DOE will coordinate a Federal integrated interagency process to consolidate Federal environmental reviews and authorizations within a standard two-year schedule while ensuring meaningful engagement with Tribes, local communities, and other stakeholders,” the article continued.

The new rule expedites the siting, permitting, and construction of electric transmission infrastructure in the United States.

Resources provided by the CITAP Program include:

Improved Permitting Review with Two-Year Timelines: DOE will serve as the lead coordinator for environmental review and permitting activities between all participating federal agencies and project developers. DOE will lead an interagency pre-application process designed to ensure that developer submissions for federal authorizations are ready for review on binding two-year timelines, without compromising critical National Environmental Policy Act (NEPA) requirements.

Sustained Integrity in Environmental Review Process: DOE will work with the relevant agencies to prepare a single NEPA environmental review document to support each relevant federal agency’s permit decision making, with the goal of reducing duplication of work. State siting authorities may participate in the CITAP Program alongside federal agencies and take advantage of the resources DOE is offering through the program.

Transparent Transmission Permitting: The CITAP Program will require a comprehensive public participation plan that helps project developers identify community impacts from proposed lines at the outset of the project and encourages early engagement by potential applicants with communities and tribes. The CITAP Program will allow potential applicants and agencies to coordinate via an online portal, which will allow project developers to directly upload relevant information and necessary documentation and will offer a one-stop-shop for their federal permitting communications. Through this online portal, participating federal agencies can also view and provide input during the initial document collection process and during federal environmental reviews.

“The Permitting Council is excited to have CITAP as a partner as we work together to bring clarity, transparency, and efficiency to the federal permitting process for crucial transmission projects,” said Permitting Council Executive Director, Eric Beightel. “The ambitious clean energy goals of the Biden-Harris administration cannot be achieved without the transmission infrastructure needed to deliver renewable energy to consumers. This rule is a significant step forward in bringing coordination and accountability into the permitting review of these vital projects, and a perfect complement to our FAST-41 permitting assistant program, enabling us to deliver clean and affordable energy to homes across the nation.”

The newly announced $331-million funding commitment will add grid capacity equivalent to powering 2.5 million homes and create more than 300 new, high quality and union construction jobs, DOE said. The funding comes courtesy of the Bipartisan Infrastructure Law and will support a new transmission line from Idaho to Nevada that will be built with union labor.

“…We are acting with the urgency the American people deserve to realize a historic rework of the permitting process that slashes times for new transmission lines, puts more Americans to work and meets the energy needs of today and the future,” said U.S. Secretary of Energy, Jennifer M. Granholm.

“In order to reach our clean energy and climate goals, we’ve got to build out transmission as fast as possible to get clean power from where it’s produced to where it’s needed,” added John Podesta, Senior Advisor to the President for International Climate Policy. “As today’s announcements demonstrate, the Biden-Harris administration is committed to using every tool at our disposal to accelerate progress on transmission permitting and financing and build a clean energy future.”

Experts say that undergrounding existing utilities to protect them from severe weather, building additional transmission and distribution infrastructure, and smart planning are just some of the improvements necessary to future-proof America’s power infrastructure.

A Grid on the Brink

Federal, state, and even local government agencies are racing to solve the country’s current energy problems and prepare for those on the horizon.

The American Society of Civil Engineers (ASCE) gave the United States’ energy infrastructure a C- in its most recent Infrastructure Report Card.

“…Distribution infrastructure struggles with reliability, with 92% of all outages occurring along these segments,” the ASCE wrote. “In the coming years, additional transmission and distribution infrastructure, smart planning, and improved reliability are needed to accommodate the changing energy landscape, as delivery becomes distributed, and renewables grow.”

The U.S., like the rest of the world, needs to generate more power, and it needs to do it more efficiently.

In the International Energy Agency’s recently released 2024 Electricity Report, which analyzes and forecasts the world’s electricity needs through 2026, the organization said that power generation is currently the largest source of carbon dioxide (CO2) emissions in the world, but it is also the sector leading the transition to net zero emissions through the rapid expansion of renewable energy sources such as solar and wind power.

“Ensuring consumers have secure and affordable access to electricity while also reducing global carbon dioxide (CO2) emissions is one of the core challenges of the energy transition,” the IEA wrote.

Per the IEA’s report, global electricity demand rose moderately in 2023 but is set to grow faster through 2026 as electricity consumption from data centers, artificial intelligence (AI), and the cryptocurrency sector is projected to double by then.

“After globally consuming an estimated 460 terawatt-hours (TWh) in 2022, data centres’ total electricity consumption could reach more than 1,000 TWh in 2026,” the IEA added. “This demand is roughly equivalent to the electricity consumption of Japan. Updated regulations and technological improvements, including on efficiency, will be crucial to moderate the surge in energy consumption from data centres.”

What Causes Leaning Towers?

Whether you’re building a tower or a rehabbing a bridge, GPRS offers a suite of subsurface damage prevention, existing condition documentation, and construction & facilities project management services designed to keep your projects on time, on budget, and safe.

You’ve heard of the Leaning Tower of Pisa – but what about the Leaning Tower of South Dakota?

In late 2023, a construction site in Rapid City, South Dakota, had to be evacuated when an elevator shaft for the 10-story, mixed-use structure began to tilt. According to local news outlet KELO, surrounding buildings and a section of a nearby street also had to be evacuated until repairs could begin.

Luke Jessen, Vice President of Development for Lloyd Construction, which is overseeing the project, said in a statement to Construction Dive that a product failed at the corner of one of the elevator shafts, causing the tower to shift one inch at its base.

(Photo courtesy of Rapid City Police Department via Construction Dive) A leaning elevator shaft on a mixed-use tower construction project in Rapid City, South Dakota forced the evacuation of not only the site, but the surrounding area.

“This is an isolated product and sequencing issue, which will be safely rectified by an erection subcontractor in the days to come by deconstructing the shaft.” Jessen’s statement said.

The incident in Rapid City is just the latest example of a leaning structure making the news.

The most famous is the aforementioned Leaning Tower of Pisa, the 60-meter medieval tower in Italy which stands about 17 feet off the vertical. That tower, however, is just one of several leaning structures in Pisa alone.

There are thousands of unintentionally tilted towers scattered throughout the world – and they’re not all historic structures. San Francisco’s Millennium Tower luxury condo required a $100-million foundation retrofit because it had been sinking since it opened to residents in 2009 and was tilting an estimated 14 inches by 2019.

The situation became more serious when the curtain wall – an exterior element of a building designed to protect it from the elements – had pulled away from the tower and created a gap that could have served as a funnel for flames in the event of a fire.

Determining the causes, consequences, and solutions for leaning buildings falls under a branch of civil engineering known as geotechnical engineering – also known as geotechnics – which focuses on the engineering behavior of earth materials.

In an article published in February 2020 on CNN Style, leading civil engineer John Burland – who designed the solutions that stabilized both the Tower of Pisa and Britain’s Big Ben – explained that the Earth itself is the most frequent culprit behind modern leaning towers.

“We are very sophisticated in our analysis now, but we still have to understand how mother nature works,” Burland said. “Mother nature lays down ground in all sorts of variable ways and unless you actually spend the money and the time investigating the ground properly – and employ people with good knowledge and experience – then you can run into big problems… If it’s mother nature then it’s human error because they haven’t investigated it properly.”

In addition to faulty construction materials – as was the case with the elevator shaft in South Dakota – soft or weak spots in the ground, unexpected geological faults, and incomplete ground investigations can also cause structures to lean.

Burland added that most of the leaning buildings he’s worked with are “not unsafe,” but that “selling space in a building that has been known to be leaning is very difficult because often the leaning is caused by some defect in construction or design.”

“The trouble with a tall building is that you can see it leaning, which people don’t like,” he added. “It might be safe, but the owners of the building are not going to be at all happy.”

CoStar Group Buys Matterport 3D Reality Capture and Digital Twin AI Technology

The firm is acquiring Matterport’s equipment, reality capture and AI digital twin tools, and “38 billion square feet” of aggregated data for $1.6 billion in cash and stocks.

On April 22, 2024, CoStar Group, Inc. announced its plans to purchase construction tech company Matterport for an estimated $1.6 billion in “enterprise value,” according to its press release.  

As one of the self-described “first adopters” of Matterport’s technology, CoStar references the wide swath of data the 3D capture technology company has amassed; “Over 12 million spaces captured in over 177 countries, and representing more than 38 billion square feet of digital property.”

It appears that another substantial reason for CoStar’s acquisition is the artificial intelligence software, Cortex, that Matterport is touting as an AI engine for digital twin generation, virtual tours, and measurements. Matterport recently added a suite of “Property Intelligence” AI features and plug-ins to aid AEC contractors working in large spaces.

However, there seems to be some question as to the accuracy rate of the AI-generated images, specifically those 2D images taken with cameras other than Matterport. An article from Geo Week News quotes Matterport business development manager Tomer Poran as saying that the AI accuracy rate for those kinds of images have up to an 8% error rate.  

Matterport maintains that its accuracy rate when using their own technology is still 1% or less.

GPRS Project Managers use Matterport technology for a variety of reality capture products & services

GPRS utilizes Matterport technology as part of our reality capture services, and our WalkThru 3D, FLRPLN, and ProCap products. It has tremendous value in its ability to capture our 99.8% accurate field markings to allow our Mapping & Modeling Team to create integrated digital twins that incorporate above and below-ground infrastructure to provide a 360-view of any site or facility.

These integrated 3D BIM models and 2D CAD drawings can even incorporate proposed design and renovation plans to avoid or eliminate clashes, utility strikes, or strikes to concrete reinforcements before they happen.

More on Matterport’s Sale

CoStar Group, the multinational corporation dedicated to “digitizing the world’s real state,” was founded in 1987 and has been on a buying spree the last few years, having previously acquired OnTheMarket, Houses.com, Homes.com, Off Campus Partners, Move, Fairmas, and RealBase, among others.

The specifics of the Matterport acquisition include a $5.50 per share purchase price. Matterport shareholders will receive a $2.75 cash pay-out and $2.75 in CoStar shares for every Matterport stock currently held.  

The $1.6 billion valuation may seem generous. However, the Costar purchase price reflects a steep downward valuation from the $9.8 billion market cap (a 480% annual valuation and 88.5 times its 2021 revenue) it boasted after its initial public offering (IPO) in 2022.

Some construction and infrastructure watchers cite Matterport’s decision to shift into a recurring revenue/subscription model as the cause of its slide. But its vast trove of aggregated data, and expanding pipeline to grow it, may be exactly what enticed CoStar to purchase them – to bolster their own data network while also wiping out potential competition.  

Or, perhaps it is as Andy Florance, CoStar Group CEO put it in the press release announcing the acquisition, “People now select their next home, apartment, office, store, hotel or warehouse on their mobile devices, often without ever visiting the property. There is no better way to remotely experience space than via Matterport.”

How Power Substation Operators Can Reduce Risk and Increase Efficiency with SiteMap®

GPRS’ GIS for electrical utilities platform, SiteMap®, helps power substation operators increase efficiency, mitigate risk, and reduce reworks during renovations, maintenance and construction.

Power substations are the veins that provide the lifeblood of America’s electrical grid.

That’s why protecting them at all costs whenever construction or maintenance is occurring near them is of the utmost importance.

3D Point Cloud of Electrical Substation
3D Point cloud of two electrical substations after being 3D laser scanned by GPRS’ existing condition documentation team.

National Grid states that “one of the main roles of substations is to convert electricity into different voltages.” This electricity is then distributed throughout the U.S. and provides the essential energy needed to thousands of homes, businesses, and buildings to keep us going along throughout our days without interruption. It’s extremely important to prevent underground electrical line damage when installing new fencing at a major substation, as was the case in Oregon, Ohio, for a well-known national security integration provider.

Electrical Substation Maintenance, Scope of Project

The contractor hired the SIM-certified team of GPRS Project Managers who have completed over 3,000 miles of Transmission ROW scanning & over 500 substation projects nationwide for major companies such as Duke Energy, American Electric Power, Ameren, FirstEnergy and Exelon, to ensure that the electrical substation construction they were performing would move forward without any hazardous utility strikes, causing potential loss of power, electrocution, or electrification of the grid around the station.

Our scope of work at the power transmission substation was to provide accurate utility location of all underground utility lines located within ten feet of both sides of the main fence that was scheduled to be replaced. This proved to be a large project for GPRS Project Manager Vijay Gentiles, who spent an entire week accurately mapping and locating telecommunication lines, electrical lines, water hydrants, an existing sanitary sewer line, as well as the entire grounding wire grid located within the fence’s domain.

Why It Matters

Power substations are high-risk areas to break ground due to essential utilities being located throughout the majority of the system. So, the best practice is hiring a nationwide subsurface damage prevention contractor such as GPRS to utilize the most cutting edge locating and mapping protocols. In this scenario and many others like it, the substation’s as-built drawings and existing condition records were out of date and incomplete, not providing the sufficient data needed to break ground with confidence on site. Crucial duct banks needed to be protected along with essential grounding grids during installation, so Gentiles sprung to action equipped with multiple forms of cutting-edge technology, including Ground Penetrating Radar (GPR), and an Electromagnetic (EM) locator to accurately map out the proposed scan boundary for all underground utilities.

What We Discovered

While on site, Gentiles had to be extremely cautious, wearing proper PPE including fire retardant clothing per OSHA standards in case of an arc flash. As he conducted his meticulous subsurface investigation, he was able to locate both electrical and telecommunication lines throughout the entirety of the substation’s fence project. He discovered a sanitary storm line in one location, but found that it would not impact the project due to its depth.

The depths of the located lines were between two to three feet underground, while the sewer line was conveniently at a depth of five to six feet, where new fence poles being installed would not reach. After accurately mapping and marking out the lines with paint or color-coded flags, as shown in the images below, Gentiles then collected all the data with a GNSS Geode used to accurately inspect, map, and collect data points of underground utility locations. The site data was then uploaded to the cloud, and within five minutes of being collected was available within our new GIS for electric & telecommunication utilities software, SiteMap®.

How do Excavation Tolerance Zones Protect Utilities?

A tolerance zone refers to the area surrounding underground utility lines where excavation work should be approached with caution to avoid damage to the utilities. The size or width of the tolerance zone for digging around utilities can differ by state. It's essential for anyone planning to excavate near underground utilities to familiarize themselves with the relevant laws, regulations, and guidelines in their state.

Failing to maintain sufficient clearance between digging equipment and underground utilities causes 13.46% of damages to buried infrastructure every year in the U.S., according to the Common Ground Alliance 2022 DIRT Report.

In every state, you must abide by federal, state, and local laws and regulations that require anyone planning to excavate near underground utilities to contact 811 or a utility locating company to have the utilities located and marked before digging begins.

Construction Safety Week (CSW) aims to connect workers and their employers with the resources they need. This annual safety initiative is May 6-10, 2024, where sponsor companies such as GPRS send their safety experts across the country to hold free presentations about a variety of safety-related topics, including tolerance zones for digging around utilities.  Click here to schedule a CSW Toolbox Talk / Lunch & Learn with GPRS.

What is a Tolerance Zone?

A tolerance zone refers to the area surrounding underground utility lines where excavation work should be approached with caution to avoid damage to the utilities. A utility locating company will place markings and flags to indicate the approximate location of a buried line. The tolerance zone typically extends a certain distance from the marked location of the utility line and may vary depending on factors such as the type of utility, soil conditions, and local regulations.

Is the Tolerance Zone Different in Each State?

The size or width of the tolerance zone for digging around utilities can differ by state and may even vary within a state based on local regulations and utility company guidelines. According to the Excavation Safety Guide, states are evenly split between using 18 inches or 24 inches in their tolerance zone definitions.

To determine the total size of the tolerance zone area, contractors must know the state’s guidelines and the size of the line or pipe. For example, the total size of the tolerance zone area for a two-inch pipe in a state with a defined tolerance zone size of 18 inches would be 38 inches: 18 inches on either side of the pipe, plus the two-inch diameter of the pipe itself.

Tolerance Zone Map

Are there Excavation Guidelines Per State?

The state also has guidelines for the methods and equipment allowed for excavation within these zones to ensure the safety of underground infrastructure and prevent damage during excavation work.

Excavators are usually required to exercise caution and use hand tools or non-destructive excavation methods within the tolerance zone to avoid accidentally damaging the utility lines, which can lead to service disruptions, safety hazards, and costly repairs. Some states only allow contractors to employ hand digging, soft digging, potholing, and vacuum excavation in the tolerance zone. They state that instruments such as pick axes, digging bars, and pointed spades should never be used.

It's essential for anyone planning to excavate near underground utilities to familiarize themselves with the relevant laws, regulations, and guidelines in their state and locality, as well as to contact a utility locating company prior to excavation. This helps to minimize the risk of damage to utility lines and ensures compliance with safety regulations.

Also, emphasizing safe digging practices, specifically within the tolerance zone, would reduce excavator errors in the field. Careful planning and adherence to safety protocols will prevent damage to underground infrastructure and ensure the safety of workers.

Many companies have comprehensive ground disturbance policies in place that helps mitigate the risk of utility strikes and damages. Ground disturbance policies typically include requirements for in-depth review and locating of utility information, and notification of community members whenever construction is going to take place. GPRS offers free ground disturbance policy reviews to help you ensure you have the procedures in place to guarantee success. Click here to request a ground disturbance policy review.

Tolerance Zone by State

How Would a Contractor Excavate Around Utilities?

Before any excavation work begins, the contractor must contact the relevant utility locating company to request utility locating services. These services involve using ground penetrating radar equipment to detect and mark the location of underground utilities, such as gas lines, water pipes, electrical cables, and telecommunications lines.

Here are the main elements that must be considered when creating or following a dig policy.

Utility Locating: Calling 811 before you dig is the law, and One Call will connect you with public utility contractors who will provide you with the location of all public utilities near your excavation. One Call cannot provide locates for the private utility lines on site, nor do they provide depths for public utility lines. GPRS professional private utility locating can locate both public and private utilities, provide accurate field markings, including depths, and give you complimentary digital and PDF utility maps of your utility infrastructure.

Review Utility Maps: The contractor will review utility maps or as-built drawings to get an idea of the location and depth of underground utilities in the area.

Define Tolerance Zone: Once the utilities are located and marked, the contractor identifies the tolerance zone.

Non-Destructive Excavation: Within the tolerance zone, the contractor may use hand tools or non-destructive excavation methods, such as hydro excavation or vacuum excavation, to carefully expose the utilities. These methods minimize the risk of accidental damage to underground infrastructure.

Visual Inspection: As the excavation progresses, the contractor visually inspects the exposed utilities to verify their type, condition, and depth. This information helps ensure that excavation activities proceed safely without causing damage to the utilities.

Temporary Support: The contractor may provide temporary support or protection for exposed utilities to prevent damage during the excavation process. This could involve shoring, bracing, or other protective measures.

Excavation Equipment and Techniques: Depending on the nature of the project and the size of the excavation, the contractor may use a variety of excavation equipment and techniques, such as backhoes, excavators, trenchers, or hand digging tools. Care must be taken to avoid striking or damaging the marked utilities during excavation.

Monitoring and Compliance: Throughout the excavation process, the contractor monitors the work area for any signs of utility damage or safety hazards. Compliance with safety regulations and best practices is essential to minimize the risk of accidents and ensure the integrity of underground infrastructure.

By following these steps and exercising caution and diligence, contractors can safely excavate around utilities while minimizing the risk of damage and ensuring the success of the project.

How Can Laser Scanning and BIM Assist MEP Contractors?

3D laser scanning and BIM models are revolutionizing MEP system installation, adding intelligence, efficiency, and safety to project execution.

The Basics of MEP Installation

Mechanical, electrical, and plumbing (MEP) installation involves a series of highly coordinated steps performed by contractors to integrate their systems into a building's structure. Throughout the installation process, contractors prioritize safety, quality, and code compliance to ensure that MEP system installations are performed safely, function properly, and are reliable for the life of the building.

Before installation begins, a general contractor would need up to date as-builts to develop MEP design plans. If existing conditions documentation does not exist or is not up to date, then the contractor would reach out to a 3D laser scanning company to scan the site and deliver accurate as-builts. Precise building layouts, dimensions, elevations, and distances ensure the successful planning and installation of MEP systems.

A general contractor would also need the locations of underground utilities (e.g. gas lines, water pipes, electrical cables, etc.) for planning and safety purposes. They would reach out to a utility locating company to conduct on-site investigations and receive up-to-date utility maps.

They will utilize comprehensive site information to plan MEP routes and coordinates with trades. Once planning is complete, the trade contractors will prepare the construction site for MEP installation by clearing obstacles and double checking that MEP systems are routed around utilities to ensure a safe working environment. They may also install temporary supports or scaffolding as needed.

Next, they will rough-in the basic framework and components of MEP systems before finishing materials are applied. Rough-in installation includes:

  • HVAC Mechanical: Ductwork, air handlers, vents, and other HVAC components are installed according to the design layout.
  • Electrical: Conduit, wiring, panels, and distribution equipment are installed to deliver power throughout the building.
  • Plumbing: Pipes, fixtures, valves, and pumps are installed to supply water, gas, and drainage systems.

Throughout the installation process, contractors coordinate closely with other trades to ensure that MEP systems integrate seamlessly with structural elements, architectural features, and other building systems.

Once the rough-in installation is complete, contractors conduct tests and inspections to verify the functionality of MEP systems. After passing inspections, contractors complete the final installation of MEP components and make any necessary adjustments.

MEP Building Information Model
Contractors work closely with other trades to ensure that MEP systems integrate seamlessly with structural elements, architectural features, and other building systems.

How Do Contractors Capture Existing Site Conditions?

Having accurate as-builts prior to MEP design planning will ensure smooth integration and installation of MEP systems with the existing building design. This is accomplished by 3D laser scanning the site.

3D laser scanners use LiDAR (light detection and ranging) technology to capture millions of three-dimensional data points of a space. Each data point is converted into a pixel with an XYZ coordinate. Millions of data points are captured and processed into a point cloud, creating an accurate 3D as-built data set of the site. The technology delivers highly accurate digital layouts and dimensions for construction professionals.

What Benefits Can 3D Laser Scanning Provide for MEP Contractors?

3D laser scanning captures as-built site conditions, assists with clash detection, optimizes spatial planning and layout, verifies system installation, and provides progressive documentation for MEP contractors.

Accurate As-Built Documentation: Laser scanning accurately captures the existing conditions of a building or site, providing detailed as-built documentation. This information ensures that MEP systems are designed and installed to fit precisely within the existing structure, minimizing clashes and rework.

Clash Detection: Laser scanning produces point clouds that can be overlaid on top of MEP design models. This provides data for general contractors to perform clash detection and identify conflicts between MEP systems and other structural and architectural building elements. By detecting clashes early in the design phase, costly on-site conflicts and revisions are minimized.

Spatial Planning and Layout Optimization: Laser scanning provides precise measurements of available space, enabling MEP engineers to optimize the layout of systems for efficient use of space and minimal interference with other building elements. This optimization can lead to more cost-effective designs and streamlined installation processes.

Upgrades or Modifications: 3D laser scanning captures precise details of existing equipment and MEP features so that upgrades or modifications can be tied into existing systems and installed with confidence, fitting seamlessly into the existing space.

Construction Verification: During construction, laser scanning can be used to verify that MEP systems are being installed according to design specifications. By comparing scan data with the design models, any deviations or discrepancies can be quickly identified and addressed.

Progress Monitoring and Documentation: Laser scanning can be used to monitor construction progress over time, providing a visual record of MEP installation at various stages of construction. This documentation can be valuable for project management, quality assurance, and ongoing maintenance.

3D laser scanning enhances the efficiency, accuracy, and coordination of the MEP installation process, improves construction workflows, and increases the quality of MEP systems.

GPRS 3D laser scanning services
3D laser scanning accurately captures the existing conditions of a building or site, providing detailed as-built documentation.

How is a 3D Building Information Model/Building Information Management Model (BIM) Created?

Once a site is 3D laser scanned, a 3D building information model (BIM) can be created from the point cloud data. A 3D BIM model provides a geometrically accurate model of a building or site, capturing spatial relationships, infrastructure and manufacturer details, property and layer information, and other pertinent aspects of the site. A 3D BIM model provides general contractors with the ability to break down building parts by elements or layers and see how they fit into a single finalized structure. General contractors can isolate walls, columns, windows, doors, etc., and plan for MEP installation.

What Benefits Can BIM Models Provide for MEP Contractors?

A BIM model can provide these benefits for MEP system installation.  

Design Planning: 3D laser scan data can be used to create detailed 3D BIM models of MEP building systems, including ductwork, piping, conduit, and electrical systems. These models provide a clear visual representation of how MEP components will fit within the existing building structure.

Clash Detection: Clash detection tools within BIM software help identify conflicts between MEP systems and other building elements, enabling early resolution of clashes to prevent costly rework during installation.

Coordination: A 3D BIM model provides a digital twin that improves communication and collaboration between different disciplines involved in the construction process, including architects, structural engineers, MEP engineers, and contractors. By working within a shared BIM environment, the project team can collaborate more effectively, share information, and coordinate their efforts to ensure that MEP systems integrate seamlessly with the overall building design.

Quantity Takeoff and Cost Estimation: BIM software can generate accurate quantity takeoffs and cost estimates for MEP components based on the 3D model. This helps MEP contractors plan and budget their installations more effectively, reducing the risk of cost overruns and ensuring that materials are ordered in the appropriate quantities.

Prefabrication: BIM enables MEP engineers to design systems for prefabrication off-site. With detailed BIM models, engineers can accurately plan the fabrication of MEP components in a controlled environment, improving quality control and reducing installation time and labor costs on-site.

Construction Sequencing: BIM can be used to aid construction sequencing for MEP system installation. By visualizing the MEP installation design plan in a virtual environment, contractors can optimize their workflows, ensure workers’ safety, and identify issues before installation.

Facilities Management: BIM models can be leveraged for facilities management purposes after construction is complete. By incorporating information about MEP systems into the BIM model, facility managers can access valuable data about equipment location, and maintenance schedules, streamlining operations and maintenance activities throughout the building's lifecycle.

Finish Drawings: A 3D BIM model can provide a record of the final state of the project, documenting any changes or deviations from the original plans or specifications that occurred during the construction process. This provides a reference for building owners, facility managers, and maintenance personnel to understand the layout, configuration, and components of the completed structure. This information is valuable for ongoing maintenance, repairs, and future renovations.

3D BIM models are revolutionizing MEP system installation, adding intelligence, efficiency, and safety to project execution.

How Recycled Foamed Glass Aggregate Could Change the Game for Infrastructure Construction

Foamed glass aggregate allows for the rapid deployment of infrastructure without the need for extensive groundwork or reinforcement that heavier materials might require. This was notably demonstrated in the rapid repair of Philadelphia’s I-95, where it was used to stabilize the ground swiftly and effectively, allowing the highway to reopen in record time after a catastrophic collapse caused by a fire.

More than half a billion glass bottles… That’s how much glass a Pennsylvania firm has reclaimed from landfills and turned into an unusual construction material: recycled foamed glass aggregate, an ultra-light type of mechanically stabilized earth (MSE) that is gaining popularity for its insulating properties and environmental benefits.

Assuming an average weight of eight ounces each, those 500 million glass bottles have an approximate weight of 125,000 tons and could circle the Earth three times. So, we’re talking about a lot of recycled glass.

Innovative materials are a cornerstone of progress in construction productivity, enabling faster, more efficient, and more sustainable practices. Recycled foamed glass aggregate is gaining popularity for its lightweight, insulating properties and environmental benefits, as it shows off its unique properties to speed construction efforts, particularly in infrastructure projects like roads and highways.

What is Recycled Foamed Glass Aggregate?

A close-up photo of the recycled foamed glass aggregate. It looks and reads to GPR like gravel, but is ultra-light compared to traditional fill.

Recycled foamed glass aggregate is made from post-consumer recycled glass, such as bottles and other glass products. The production process begins by grinding the glass to a powder, which is then mixed with a foaming agent, typically silicon carbide. This mixture is heated in a kiln, where the foaming agent reacts to the heat, creating millions of tiny bubbles within the glass, transforming it into a highly porous, lightweight material. Once cooled, this material is crushed into aggregate sizes that can be used in various construction applications like widening roadways, acting as fill under concrete slab foundations, and insulating electrical transmission lines, among others. The EPA gave the material the green light back in the 1980s, but it has just recently been gaining traction and has been approved for use in more than 22 states in the U.S.

Applications in Construction

The primary application of foamed glass aggregate is in construction projects where weight reduction on underlying structures is crucial. It is an excellent fill material for highway expansions, providing a solid yet lightweight substrate that can support heavy loads without compromising the integrity of existing underground utilities. The material’s light weight reduces the stress on underlying structures, making it ideal for projects over sensitive areas, such as water pipes and sewage systems.

The aggregate is also used extensively as backfill for retaining walls and as a base layer for roadways and foundations. Its drainage properties, resistance to weather conditions, and portability, coupled with its mechanical stability, can make it a solid choice for fill in areas prone to water retention and flooding.

Rather than requiring eight-inch lifts like topsoil or fill, the aggregate can be placed in 24-inch lifts, so you get faster vertical build, with much less compaction required and no need to wait for optimal moisture conditions before adding weight.

According to Aero Aggregates of North America, LLC’s CEO, Archie Filshill, you can “take away two feet of soil, install 12 feet of foamed glass, with no additional weight. It’s a six to one conversion.”

Environmental Impact & Sustainability

One of the most compelling aspects of recycled foamed glass aggregate is its contribution to environmental sustainability. The use of recycled glass helps divert waste from landfills and reduces the demand for virgin raw materials. Moreover, the energy required to produce the MSE is significantly lower than that required for traditional fill materials like crushed stone or sand.

And an unusual property of the material is that it can be easily deconstructed and repurposed into another construction project by simply scooping it out of its location and placing it at its next one, with no other reclamation processes required.

Insulating Properties and the R-factor

Recycled foamed glass aggregate is a closed cell foam, so it has an R-factor value of 11.5 to 15.7 and boasts excellent insulating properties. The R-factor indicates the material's resistance to heat flow; the higher the R-factor, the better its insulating capabilities. In the context of infrastructure, using glass aggregate can help improve the energy efficiency of buildings and roads by providing a thermal barrier. This is particularly beneficial in utility insulation, where maintaining temperature control is crucial, which is why it has been used as insulation for power transmission lines without fear of damage.

Impact on Highway Expansion & Construction

The lightweight nature of foamed glass aggregate has made it a game-changer in highway expansion and construction projects. It allows for the rapid deployment of infrastructure without the need for extensive groundwork or reinforcement that heavier materials might require. This was notably demonstrated in the rapid repair of Philadelphia’s I-95, where it was used to stabilize the ground swiftly and effectively, allowing the highway to reopen in record time after a catastrophic collapse caused by a fire.

Aero Aggregates of North America, LLC played a vital role in getting last year’s I-95 repairs completed in record time to get Philadelphians back on the road.

Integration with Concrete Construction

The lightweight material can also be integrated into concrete construction as a lightweight aggregate and insulator. This integration not only reduces the overall weight of the concrete but also enhances its thermal and acoustic insulating properties. Its use in concrete is advantageous in urban settings where noise reduction and energy efficiency are priorities. For example, you can place a foot of aggregate instead of layers of stone and Styrofoam under a slab, and achieve a similar R-factor, with significantly less weight.

From a construction safety & utility infrastructure mapping perspective, the aggregate “reads” much like a layer of gravel for ground penetrating radar (GPR) and EM locators, so there is no concern about it interfering with subsurface utility as builts or mapping.

Future Prospects & Innovations

The future of recycled foamed glass aggregate in construction looks promising, with ongoing research and development aimed at enhancing its properties and expanding its applications. Innovations in the composition and manufacturing process could see it becoming a standard material in even more areas of construction and civil engineering.

Overall, this material signifies a significant step forward in the quest for more sustainable and efficient construction materials. Its unique properties, such as the R-factor and utility insulation capabilities, combined with its environmental benefits, make it a potentially valuable asset in modern construction, particularly in infrastructure projects like highway expansion and concrete construction. As the construction industry continues to evolve, the role of innovative materials like this will undoubtedly expand, paving the way for more sustainable and resilient infrastructure development.

Is Waterless Concrete Part of the Construction Industry’s Future?

Waterless concrete represents a significant step forward in the pursuit of sustainable construction.

Sustainability is a significant concern in the construction industry, driving innovation in materials and methods.

One such groundbreaking development is waterless concrete, a new formulation designed to address environmental concerns while maintaining the strength and durability essential for modern construction.

That idea is being taken to new heights – literally – as part of a project designed to test new lunar construction materials in preparation for NASA’s planned 2025 return to the moon.

Three men look at scientific equipment on a table.
LSU and scientists from NASA Marshall Space Flight Center in Alabama have partnered to research the use of native raw materials readily available on the surface of the Moon and Mars – namely sulfur and regolith – to develop 3D-printed waterless concrete.

According to a press release on Louisiana State University’s website, LSU and scientists from NASA Marshall Space Flight Center in Alabama have partnered to research the use of native raw materials readily available on the surface of the Moon and Mars – namely sulfur and regolith – to develop 3D-printed, waterless concrete.

The project is in support of the overall goal of NASA’s return to the Moon: to explore its south pole and begin the process of establishing a long-term presence there.

“Molten sulfur is the binder and regolith, i.e. Lunar soil, acts as the filler material,” said LSU Bert S. Turner Construction Management Assistant Professor Ali Kazemian. “Robotic construction on the Moon using Lunar resources and large-scale 3D-printing technology is the goal. Even shipping raw materials from Earth is cost prohibitive, so the only practical approach is to use the resources which are already available on the Moon and Mars for construction. That is why 3D printing using sulfur-regolith concrete (SRC) is attractive. On the other hand, production of Portland cement concrete, the most commonly used construction material on Earth, will be complicated on the Moon and will require large amounts of water that could otherwise be used for life support or other exploration activities.”

Funded through a $200,198 grant from the National Science Foundation, the work will be carried out at LSU and the NASA Marshall Space Flight Center. The team will study the extrusion parameters and interplay between material-process-environment factors during high-temperature SRC extrusion and test the space resilience of 3D-printed SRC specimens under vacuum conditions and temperature swings, extreme thermal load resistance, and simulated micrometeorite impact resistance.

“The planned research tasks will provide a fundamental understanding of the impacts of high-temperature, extrusion process parameters and environmental factors, such as near-vacuum conditions, on the performance of 3D-printed SRC structures,” Kazemian said. “After reaching these objectives, together with our NASA Colleagues, we will work on design and development of a large-scale SRC 3D-printing system at NASA Marshall to validate our research findings on a large scale. For example, by 3D printing a Lunar habitat analog…”

Whether created with extraterrestrial material, or Earth-bound products, waterless concrete represents a significant step forward in the pursuit of sustainable construction. By eliminating the need for water in the concrete mixing process, this innovative material not only conserves a precious natural resource but also offers a more environmentally friendly alternative to traditional concrete.

What is Waterless Concrete?

Waterless concrete, also known as dry concrete, is a type of concrete that does not require water for mixing or curing. Traditional concrete production involves mixing cement, water, and aggregates like sand and gravel. The chemical reaction between water and cement allows concrete to set and harden. However, waterless concrete uses a different chemical process that eliminates the need for water, relying on chemical additives and reactions to achieve the necessary binding and hardening properties.

Composition and Production

The key to waterless concrete lies in its innovative composition. Manufacturers replace water with chemical activators that trigger the hydration process of cement. These activators are often composed of various compounds that can efficiently initiate and sustain the hydration process without external water. Additionally, waterless concrete incorporates superabsorbent polymers that help in retaining any intrinsic moisture within the mix, which is crucial for the curing process.

The production of waterless concrete involves mixing cement, aggregates, and specific chemical activators under controlled conditions. This process not only reduces the dependence on water but also results in a faster setting time, making it highly beneficial for rapid construction scenarios.

Environmental Benefits

One of the most significant advantages of waterless concrete is its environmental impact. The traditional concrete production process is water-intensive, consuming large quantities of water. By eliminating the need for water in concrete, we significantly reduce water use in construction, conserving this vital resource for other needs, especially in arid regions or places with water scarcity.

Furthermore, waterless concrete contributes to reducing the carbon footprint of construction activities. The production of cement, a primary component of traditional concrete, is energy-intensive and generates considerable amounts of CO2. Since waterless concrete can be formulated to use alternative and less carbon-intensive binders, it offers a greener alternative to conventional concrete.

Applications and Limitations

Waterless concrete is particularly useful in environments where water is scarce or where rapid construction is necessary. It has potential applications in desert regions, in military construction, in space exploration habitats, and in emergency constructions such as flood barriers or temporary shelters in disaster-struck areas.

However, the adoption of waterless concrete also faces certain limitations. The cost of chemical activators can be higher than the traditional water-based mix, making it more expensive in current market conditions. Moreover, because it's a relatively new technology, there may be challenges related to long-term durability and behavior under different environmental conditions, which are still under research and testing.

The Future of Waterless Concrete

As the technology develops and more research is conducted, the applications and efficiency of waterless concrete are expected to expand. Innovations in chemical additives and further understanding of the material's properties could lead to wider acceptance and usage in the construction industry. Additionally, as environmental regulations become stricter and water scarcity issues increase, the demand for sustainable construction materials like waterless concrete is likely to grow.

Efforts to make waterless concrete more cost-effective are also crucial for its adoption. This could involve finding cheaper sources of chemical activators or improving the manufacturing process to reduce costs. Furthermore, education and training for engineers and construction workers in the use of waterless concrete will play a vital role in its integration into mainstream construction practices.

GPRS offers comprehensive, precision concrete scanning and imaging services designed to keep you and your team safe, your budget intact, and your projects on time.

GPRS Concrete Scanning Solutions Ensure Safe Cutting & Coring

As the construction industry continues to evolve towards greener practices, waterless concrete is poised to play a crucial role in shaping the future of construction, making it an exciting area for ongoing research and application.

Of course, no matter the composition of the concrete, it’s important to know what’s embedded within a slab before you cut or core.

GPRS offers comprehensive, precision concrete scanning and imaging services designed to keep you and your team safe, your budget intact, and your projects on time.

Concrete coring comes at a risk to you and your team – as well as your budget and schedule. GPRS’ SIM-certified Project Managers (PMs) are equipped with multiple technologies to clear areas prior to you core drilling and/or anchoring. Upon completion of the scanning process, you will have a clear layout of the vertical and horizontal position of impediments such as post tension cables, rebar, beams, and conduits. Our scanning and imaging services can be completed on any surface you might be working on, including concrete slabs, walls, columns, and beams.

As with concrete coring, it’s crucial to locate unseen or buried objects prior to saw cutting into slab-on-grade concrete. You don’t want to risk severing post tension cables, rebar, conduits, pipes, grade beams, or any of the other obstructions that could be inches from your saw blade. GPRS concrete scanning and imaging services mitigate these risks by utilizing both ground penetrating radar (GPR) scanning and electromagnetic (EM) locating to visualize what is inside and underneath your concrete slab.

We are so confident in our PMs that we introduced the Green Box Guarantee, which states that when we place a Green Box within a layout prior to anchoring or coring concrete, we guarantee that the area will be free of obstructions.

If the area isn’t free of obstructions when you core or cut, GPRS will pay the material cost of the damage.

Frequently Asked Questions

Can GPR determine the difference between rebar and electrical conduit?

Ground penetrating radar can accurately differentiate between rebar and electrical conduit in most cases. We have an extremely high success rate in identifying electrical lines in supported slabs or slabs-on-grade before saw cutting or core drilling.

Additionally, GPRS can use EM locators to determine the location of conduits in the concrete. If we can transmit a signal onto the metal conduit, we can locate it with pinpoint accuracy. We can also find the conduit passively if a live electrical current runs through it.

The combined use of GPR and EM locating allows us to provide one of the most comprehensive and accurate conduit locating services available.

Do all concrete scanning companies offer a green box guarantee?

No, the Green Box Guarantee is an industry-leading, proprietary program GPRS created to help prevent injuries and damages. We want to provide you with the peace of mind that comes with knowing you and your team can safely core and drill into concrete without worrying about subsurface damage. GPRS offers this program as part of our pursuit of 100% subsurface damage prevention. We are the only company that can provide the Green Box Guarantee, because we’re the only company that can lean on our industry-leading 99.8%+ accuracy rate for concrete scanning projects.

Construction Industry Facing Mental Health Crisis

Mental illness is just as dangerous to a construction worker as silica exposure, or slips, trips & fall hazards.

Mental illness is just as dangerous to a construction worker as silica exposure, or slips, trips & fall hazards.

In 2022, the construction industry ranked second highest in the U.S. for worker suicide rates, with 45.3 incidents per 100,000 workers. According to the Centers for Disease Control and Prevention (CDC), construction is one of multiple major industry groups with a suicide rate that is higher than in the total civilian noninstitutionalized working population.

According to the National Institute of Mental Health, the suicide rate among males was 4 times higher (22.8 per 100,000) than among females (5.7 per 100,000) in 2021. Per the Bureau of Labor Statistics, 97% of the U.S. construction workforce is male.

A construction worker sits on a windowsill looking at their phone.
Numerous non-profits and other organizations are joining construction companies in pouring resources into addressing the industry’s mental health crisis.

Also, per the Bureau, about two-thirds of those employed in the construction industry were 25-to-54 years old. According to the CDC, there were more suicides in the 25–44-year-old age demographic than any other age group in both 2021 and 2022.

“We have to keep reminding everyone that mental health issues in the industry are really common,” Alberici Constructors Safety Director, Kathi Dobson, recently told Construction Dive. “The proportion of individuals impacted because of factors outside of the job site, incidents on the job site, elements of the job site, etc. compounded by substance abuse is significant.”

Numerous non-profits and other organizations are joining construction companies in pouring resources into addressing the industry’s mental health crisis.

Construction Safety Week (CSW) aims to connect workers and their employers with the resources they need to discuss and address mental health awareness in their organizations. This annual safety initiative returns May 6-10, 2024, and will see sponsor companies such as GPRS sending their safety experts across the country to hold free presentations about a variety of safety-related topics, including mental health awareness.

“Given the high-stress nature of the construction industry, characterized by tight deadlines and long hours, the surge in mental health concerns is undeniable,” said Jason Schaff, GPRS’ Senior Vice President of Marketing & SiteMap® Product Executive. “It’s great to witness CSW and GPRS actively promoting awareness around this critical issue.”

The first thing to remember if you or someone you know needs help with a mental illness issue is that you are not alone. There’s no need to be afraid of reaching out, and you can start by connecting with someone you trust for advice, such as a friend, family member, coworker, or faith leader.

  • Inability to perceive changes in one’s own feelings, behavior, or personality
  • Multiple physical ailments without obvious causes (such as headaches, stomach aches, vague and ongoing “aches and pains”)
  • Overuse of substances like alcohol or drugs
  • Thinking about suicide

In a recent article on Construction Dive, CSW organizers urged leaders in the construction industry to prioritize creating a safe space and a culture of trust and leading by example by prioritizing their own mental health.

“Everyone’s mental health is highly unique to themselves with no singular journey,” author and Flourish Psychotherapy founder & CEO, Laurie Sharp-Page, told the publication. “People cope in different ways. It’s important for organizations to have space for every individual. You can’t force someone to take care of mental health. You can help support them.”

Utility GIS Mapping: Revolutionizing Accuracy Before Digging with SiteMap®

GIS utility mapping with SiteMap® can help keep your job sites on budget, on time, and safe with accurate underground utility data.

With over 20 million miles of underground utility lines scattered on both public and private property, and a utility strike occurring every 62 seconds in the U.S., the need for accurately mapped and securely stored utility Geographic Information System (GIS) mapping data on every job site, everywhere, is paramount for the mitigation of future underground utility damages.

The utility GIS mapping industry has a major problem, however, that first needs to be solved before this goal can be accomplished.

The Challenge of Inaccurate Data

Despite the clear benefits of GIS utility mapping, the industries reliance on outdated and inaccurate data to populate these systems has led to many issues. Data within current utility GIS mapping platforms, while intuitive, lacks accuracy and is usually based on municipalities’ outdated and inaccurate paper plans referenced from centerline data, or eyeballed "measurements," or is based on some as-builts, GPR sketches, and hard copy old-school data that isn’t that valuable. Much of this data is compartmentalized, causing data and communication siloes among team members within municipalities, campus facilities, and construction crews. These issues result in major headaches like project downtime and reworks due to underground utility strikes.

What is GIS Utility Mapping?

GIS utility mapping in theory, is the process of accurately locating and digitally mapping the precise location of all underground utility lines within a municipality, construction site, or facility using a Geographic Informational System. Water, gas, electric, communication, irrigation and sewer utility data are generally stored within the system, with the purpose of providing a comprehensive record of all of the underground infrastructure of a facility or property.  

Rolled up utility maps
You can’t properly plan for a construction project without accurate existing condition documentation.

The issue with much of this data, however, is that it is based on maps and as-builts that were incorrect when they were initially uploaded into the system. When this data is then relied upon to either mark utilities on the ground or make digging and design decisions so that excavation, drilling or boring can  take place, utility damages result.

To address the ongoing issue of bad as-built data resulting in bad utility GIS mapping data, GPRS created SiteMap® (patent pending). SiteMap® is the first-ever GIS Utility Mapping platform that is composed of 99.8%+ accurate data collected in the field by SIM-certified GPRS Project Managers. Every bit of the utility data displayed within SiteMap®, including but not limited to: water, gas, electric, communication, irrigation and sewer lines, is collected by the nationwide network of boots on the ground GPRS Project Managers. This constant variable is the x-factor between SiteMap® and other utility GIS mapping platforms such as ArcGIS FieldMaps.

SiteMap®: An ArcGIS Alternative

ArcGIS, while likely the most well-known and widely used GIS platform, has many amazing benefits to it, it falls short in providing the up-to-date and accurate underground utility data needed for most contractors, municipalities, engineers, and facility managers to make safe digging decisions. This is because most of ArcGIS's utility information, generally supplied by local municipalities across the U.S., is often based on decades-old centerline data and outdated paper plans.

This is not the fault of ArcGIS, as they are uploading the data which they are given, but if the data uploaded into the system is bad, then the data that is displayed and depended upon by the end user isn't going to be accurate. The difference provided by SiteMap® is that the data within the system is collected in real time as GPRS Project Managers perform utility mapping services in the field throughout the country and upload that data to SiteMap®.

GPRS Market Segment Leader Nate Stair shares how GPRS customers who have used other GIS-based platforms and as-built documentation have experienced accuracy issues in their data.“I frequently hear that other platforms are great, except for the accuracy of the data. I have heard of lines being over 30 feet off. Yes, 30 feet!!! Yes, the line was collected, but the accuracy is almost useless. These [GIS] platforms aren't acting as a living, breathing database like SiteMap®, being tied to GPRS scanning services provided for them.”

The SiteMap® Difference: Accurate Data

The SiteMap® Mobile App provides you with utility GIS mapping data at your fingertips, 24/7 from any tablet or mobile device.

What sets SiteMap® apart from other utility GIS mapping platforms like ArcGIS is the meticulous process of data collection and mapping carried out by GPRS's Project Managers through SIM or Subsurface Investigation Methodology that results in accurate data within the system.

Map of underground utilities at job site
SiteMap® provides you with aggregated, real-time utility data of your job site, so you can dig without fear of damaging underground infrastructure.

SIM is the secret to GPRS’ 99.8% accuracy rating in utility mapping. And that 99.8% accurate data is directly uploaded into our GIS Utility Mapping application, SiteMap®.

SIM mandates the proper equipment, training, and processes for locating contractors to achieve the most accurate results. In the last five years, it has an over 99.8% success rate on over 500,000 projects across the U.S. for GPRS Project Managers, helping to ensure the data within SiteMap® is world class.

SIM is broken into three main categories. Training, Methodology, and Equipment. SIM training includes one-on-one mentorship, in-person classroom instruction by industry experts, and on-the-job field training for two to three months. The methodology that makes SIM-certified Project Managers so effective and the data they collect and upload into SiteMap® so accurate is a systematic, methodical yet flexible approach to utility locating that Project Managers perform on each and every project. This solid, repeatable methodology ensures that each Project Manager can perform the same service and achieve the same results on any project, nationwide.

The final piece of what makes data within SiteMap® much more accurate than that offered elsewhere is the equipment used to collect the data. SIM requires the use of multiple forms of technology on each investigation with the most effective and commonly used being electromagnetic (EM) locators and ground penetrating radar (GPR). The SIM methodology, when rigorously followed, allows Project Managers from GPRS to be the most accurate utility locators in the country. Meaning that the utility locating data within SiteMap® is 99.8% accurate, every time. Regardless of the Project Manager’s tenure, the application of SIM protocols and training allows each locator to achieve industry-best results, so projects can be strike-free for general contractors, municipalities, engineers and facility managers, while remaining on time, on budget, and most importantly, safe.

Build Better With SiteMap®

SiteMap® provides accurate Utility GIS Mapping Data in the palm of your hand.

With millions. of miles of underground utility lines scattered throughout the country and utility strikes occurring close to every minute, the need for an up to data utility GIS mapping platform that ensures accuracy, enhances collaboration, and eliminates data and communication siloes between key stakeholders is more important than ever.

GPRS’s Utility GIS Platform SiteMap® meets this need to eliminate utility strikes for general contractors, municipalities, engineers, and facility managers, as it supplies users with an accurate GIS utility mapping platform that includes the tools and systems in place to view, layer, deconstruct & securely share the data Project Managers collect in the field and upload into the system.

In GIS utility mapping controlling data = controlling damage, and controlling damages controls costs. When the data is accurately located, marked, mapped, and stored in GIS utility mapping software the first time it’s collected, damages on the job can be reduced and workers can go home safe to their families.

Frequently Asked Questions:

How is SiteMap® different from other GIS Platforms?

The data provided within SiteMap® is backed by GPRS’ SIM- certified Project Managers 99.8%+ accuracy on over 500,000 projects across the country within the past five years. Other platforms may provide data that is over 30 feet off from where it is actually located, which is why having a SIM-certified GPRS Project Manager actually collect that data in the field and upload it within SiteMap® makes all the difference in the accuracy of the data displayed within the platform in comparison to other GIS platforms.

Can lines be updated in the system as new infrastructure is added and projects occur on my job site?

Yes. As SiteMap® data is supplied by GPRS Project Managers, the GIS Utility Mapping Platform will upload new data while allowing you and your team to have up to date file of where lines have been re-located or newly installed after our utility mapping service in the field has been completed and uploaded to SiteMap®.

What is the Difference Between Level of Detail and Level of Development?

There is often confusion in the construction and engineering industry regarding level of detail and level of development. The acronym LOD can be used to describe both level of detail and level of development. AEC professionals tend to use these terms interchangeably; however, there are important differences.

There is often confusion in the construction and engineering industry regarding level of detail and level of development. The acronym LOD can be used to describe both level of detail and level of development. AEC professionals tend to use these terms interchangeably; however, there are important differences.

Level of detail and level of development are both used in the AEC industry to describe the amount of information and detail included in a 3D building information model (BIM). The main difference is that level of detail refers to the graphical representation of an object, while level of development refers both to the graphical representation and to the information properties of that object.

There is a defined set of LOD specifications for both level of detail and level of development that help AEC professionals document, articulate, and specify BIM models effectively. By using these LOD specifications to scope projects, architects, engineers, and other construction professionals can clearly communicate the precision requirements of the BIM model for faster project execution.

LOD Specifications
There is a defined set of LOD specifications for both level of detail and level of development that help AEC professionals document, articulate, and specify 3D BIM models effectively.

Level of Detail vs. Level of Development

While the two terms are related, they have different meanings when it comes to the 3D modeling of laser scan data. Level of detail is more focused on the visual detail, while level of development is more focused on the completeness and accuracy of the information included in the model.

What is Level of Detail for BIM?

The level of detail refers to the amount of graphical and non-graphical information associated with each element of the building information model. This can be thought of as the graphical depiction and associated text properties of each element in the model. LOD defines the amount of detail and accuracy of the elements within the model. It's typically categorized into five different levels, with higher levels indicating more detail and accuracy.

Level of Detail
The level of detail refers to the amount of graphical and non-graphical information associated with each element of the building information model.

BIM Level of Detail (LOD) – LOD 100, 200, 300, 400, 500

LOD 100

LOD 100 modeling represents the envelope of objects with simple volumes. Models are designed in a symbolic and generic way. Elements are not fully detailed and may come from other models of the same type. An LOD 100 model can be useful for a simple pre-design study, to conceptualize an idea, or to conduct a basic feasibility study that only requires a rough representation of the volumes of the building or site.

LOD 200

Models are graphically created in a simplified way and are recognizable as an object. The objects remain generic – the position, orientation, shape, and size of the geometric objects are approximate. Specifications such as material characteristics are not integrated in an LOD 200 model.

LOD 300

Models offers more precise geometry of objects and includes accurate quantities, shapes, positions, and orientations.

LOD 400

Models are realistically plotted, with quantities, shapes, positions, and orientations being accurate. Walls, slabs, and ceilings are modeled in such a way that the various layers that compose them are detailed. The purpose of this level of detail is to provide detailed and accurate geometric references. LOD 400 models become a reference point for design and construction planning.

LOD 500

The level of detail LOD 500 is equal to that of the LOD 400, but with all modeled elements verified in the field. This delivers an as-built model of the building, site or asset.

What is Level of Development for BIM?

Level of development refers to the depth of thinking applied to the modeled element within the building information model. Another way to say this is that Level of Development is the completeness of information included in the 3D model, such as the detail about the structural elements, MEP systems, or materials. Each defined “level” outlines requirements to specified visual detail and attached information for an individual modeled element. It also refers to how reliable the depiction and associated properties of the modeled object are.

Level of development specifications guide AEC professionals to develop reliable and understandable building information models (BIM). There are typically five levels of development that are used: the LOD 100, 200, 300, 400, and 500 definitions are produced by the AIA (American Institute of Architects), and the LOD 350 was developed by the BIMForum working group.

Level of Development
Level of development refers to the depth of thinking applied to the modeled element within the building information model.

BIM Level of Development (LOD) – LOD 100, 200, 300, 350, 400, 500

LOD 100 – CONCEPTUAL

The model element is graphically represented by generic shapes or symbols with approximate geometry, size, shape, location, and orientation. This level is to gain an understanding of the design and the spatial environment.

LOD 200 – APPROXIMATE GEOMETRY

In this level, model elements are graphically represented within the model as a generic system, object, or assembly with approximate specifications, quantities, size, shape, location, and orientation. Any information derived from LOD 200 elements must be considered approximate. LOD 200 models are often used for schematic design purposes.

LOD 300 – PRECISE GEOMETRY

The model includes accurate geometry with specific quantities, sizes, shapes, locations, and orientations of the elements with detailing, fabrication, assembly, and installation information. It's often used for generating construction documents, for design planning and for coordination among disciplines.

LOD 350 – PRECISE GEOMETRY WITH CONNECTIONS

The model element is graphically represented within the model as a specific system, object, or assembly in terms of quantity, size, shape, location, orientation, and interfaces with other building systems. LOD 350 is intended to define requirements for model elements that are sufficiently developed to support construction-level coordination. If a CAD design team has craft knowledge available, they can develop elements to LOD 350 or higher.

LOD 400 – FABRICATION-READY GEOMETRY

At this level, the model element is graphically represented as a specific system, object, or assembly in terms of size, shape, location, quantity, and orientation, detailing, fabrication, assembly, and installation information. At this level, the elements already have the information of a LOD 300, plus the parameters and precise geometry of a specific product, its model, manufacturer, cost, etc. This would be a fabrication level model.

LOD 500 – AS-BUILT MODEL

This is the highest level of detail, and the level is known as an as-built. The modeled element is a field verified representation in terms of size, shape, location, quantity, and orientation. This model is a close replica of the existing building. This LOD generally contains 100% of the necessary information for decision making. LOD 500 models are typically used for facility management and maintenance purposes.

How Does LOD Relate to 3D Laser Scanning?

Efficient communication and collaboration are important during a design or construction project. LOD specifications were designed to standardize models and eliminate questions in the level of detail or level of development included in a building information model. It is important to understand that LOD’s were not originally designed with laser scanning in mind, and therefore not all of the language pertains or relates directly with the technology.

3D laser scanning captures accurate data of a structure or site in the form of a point cloud. This point cloud data is used to generate BIM models through extraction software, tracing methods, and interpretation. This can be done at many different levels of detail and levels of development. It is important to specify the LOD when developing the project proposal. If you are unsure what to spec, one of our GPRS team members can walk you through the detail included in each LOD specification.

CAD designers will model building elements to the LOD specification that is defined in the project proposal. The higher the LOD, the more detail required for the modeled element of interest. LOD specifications can vary throughout the model, often based on element categories, or other grouping methodology. This helps optimize modeling efforts to those elements important to the specific project. LOD specifications also inform the project engineers and designers how much they can rely on details in the building information model. This information allows them to communicate with other team members about the usability and limitations of the model.

Frequently Asked Questions

What is BIM?

Building information modeling (BIM) is an intelligent software modeling process that engineers, contractors, and architects can use to collaborate on a building’s design, construction, and operation. BIM encompasses not only geometry and spatial relationships, but it also documents building features, such as specific information about the type of materials used, the quantity used, and how those characteristics impact the building as a whole. BIM can be thought of as a database of information ranging from project materials and cost to the 3D model after construction. This information can be used to actively manage a project every step of the way.

What is level of development in construction?

LOD in building information modeling (BIM) stands for level of development, representing the degree of detail and accuracy in the modeling of building elements. It ranges from LOD 100 (conceptual) to LOD 500 (as-built). At LOD 100, basic representations are conceptual, progressing to LOD 500 where elements are precisely as-built. This level of development classification is crucial for communicating with the project team and ensuring the correct level of accuracy for construction documentation.

What is 3D laser scanning?

3D laser scanners use LiDAR (light detection and ranging) technology to map millions of data points of a project site. The primary way a laser scanner works is to send light pulses at high speeds which reflect off objects and return back to the scanner’s sensor. For each pulse, the distance between the scanner and object is measured by determining the elapsed time between the sent and received pulses. Each data point is converted to a pixel with a known x, y, and z coordinate.

Millions of data points from multiple positions and viewpoints are captured and processed into a point cloud, creating an accurate 3D as-built data set of the site. This all happens very quickly, with some scanners, like the Leica RTC360, capturing and calculating 2 million data points per second with 2-4 mm accuracy. The result is a complete and accurate set of real-time data which can be mined for information or processed into customized 2D CAD drawings and 3D BIM models at any level of detail.

Understanding the Data Center Construction Boom

As concerns over data usage continue to grow in our ever-connected world, so too will the need for more and more data centers. But concerns, including the sustainability of these buildings, the power they require to operate, and the resources necessary to build them, will have to be addressed if today’s construction trends are going to continue into tomorrow.

As the digital landscape intensifies in our increasingly connected world, the demand for data centers is set to rise correspondingly. However, the sustainability of these facilities, their energy consumption, and the materials required for their construction must be considered to sustain current construction trends into the future.

A data center serves as a hub that contains the computational and storage capacities essential for the delivery of shared applications and data. Smaller organizations might accommodate these facilities within a dedicated room of an existing building, while larger organizations typically operate several centers exclusively for their extensive data storage and sharing requirements.

The surge in data center construction in the U.S. is largely attributed to the COVID-19 pandemic. As the pandemic kept most Americans home, driving up online shopping, companies from Amazon to Walmart had to significantly expand their data processing capabilities.

As concerns over data usage continue to grow in our ever-connected world, so too will the need for more and more data centers. But concerns including the sustainability of these buildings, the power they require to operate, and the resources necessary to build them, will have to be addressed if today’s construction trends are going to continue into tomorrow.

Continuing post-pandemic, this growth remains robust. Coldwell Banker Richard Ellis (CBRE), the largest commercial real estate services and investment firm in the world, recently released their latest North American Data Center Trends Report which reveals that 2023 saw an unprecedented 2,287.6 megawatts (MW) of data center construction across key global markets. Megawatts serve as the unit of measurement for the power capacity of a data center.

“Data center construction is at an all-time high, driven by strong demand from all users, including AI, hyperscale and enterprise,” CBRE’s Executive Managing Director for Data Centers Solutions, Pat Lynch, told the Building Design + Construction Network. “New and existing uses of artificial intelligence cases grew tremendously in the first half of the year, and we expect demand to remain strong with AI driving leasing opportunities in the second half of the year.”

There are more data centers in the U.S. than in any other country on Earth – and it’s not even close.

As of March 2024, there were 5,381 data centers operating in the U.S., according to data from Statista.com. Germany has the second-most data centers of any country in the world – with just 521. China and India, the first and second most populous countries in the world, respectively, have just 612 data centers combined.

More Power Needed

Fueling America's expanding fleet of data centers requires substantial power, putting increasing pressure on our aging electrical grid.

The American Society of Civil Engineers' latest Infrastructure Report Card graded America’s energy infrastructure at a C-, highlighting significant concerns about its reliability.

“The exponential growth of data centers with a tremendous appetite for electricity rapidly is outpacing the capacity of utilities to meet their needs,” writes Jack Rogers on Globest.com. “Pushing data center developers to prioritize new markets where they can be sure they can hook up to the grid.”

This is not just an American issue.

The International Energy Agency recently released its 2024 Electricity Report, which analyzes and forecasts the world’s electricity needs through 2026. The report highlights the data center sector’s impact on electricity consumption, positing that its global electricity demand could double towards 2026.

“We estimate that data centres, cryptocurrencies, and artificial intelligence (AI) consumed about 460 TWh of electricity worldwide in 2022, almost 2% of total global electricity demand,” the IEA wrote. “Data centres are a critical part of the infrastructure that supports digitalisation along with the electricity infrastructure that powers them. The ever-growing quantity of digital data requires an expansion and evolution of data centres to process and store it.”

The report goes on to explain that there are two main processes accounting for data centers’ electricity demands; computing and cooling each account for about 40% of the demand, while the remaining 20% comes from other associated IT equipment.

“Future trends of the data centre sector are complex to navigate, as technological advancements and digital services evolve rapidly,” the IEA continued. “Depending on the pace of deployment, range of efficiency improvements as well as artificial intelligence and cryptocurrency trends, we expect global electricity consumption of data centres, cryptocurrencies and artificial intelligence to range between 620-1,050 TWh in 2026, with our base case for demand at just over 800 TWh – up from 460 TWh in 2022...”

The data center industry is exploring solutions to its power needs, including investing in renewable energy. Data from S&P Global shows that U.S. wind and solar capacity contracted to data center providers and customers jumped 50% year over year as of early 2023, to more than 40 gigawatts.

Another potential solution to data centers’ power needs is being explored in West Texas, where Lancium, an energy and data center management firm, is building data centers close to power generating sites in a bet that this will allow them to tap into underused clean power. If their plan works, it could shift where in the U.S. developers prioritize building new data centers.

“It’s a land grab,” Lancium President Ali Fenn told The New York Times in a February 2024 article.

In lieu of building from scratch, data center developers are increasingly turning to adaptive reuse to build the facilities their clients need quicker, with fewer materials, and with a smaller initial carbon footprint.

The challenge with adapting an existing structure to serve as a data center is that unlike building from the ground-up, there’s no one-size-fits-all strategy that a developer can implement.

Rehabbing an abandoned mall is a very different task than retrofitting a disused warehouse. Some adaptive reuse projects may be able to take advantage of the existing infrastructure of the building, while others may need to start over with new power distribution, cooling, and related systems. There may be historic preservation requirements, re-zoning issues, or other hurdles that need to be overcome.

“[Adapting an existing structure into a data center] will require more collaboration between owners, engineers, architects, and contractors to ensure that all requirements can be satisfied within the existing structure,” wrote David Hart of MOCA Systems, Inc. in a piece for Data Center Knowledge. “Identifying and communicating anticipated obstacles early fosters the stakeholder alignment needed to prevent budget overruns, schedule slips, and unfulfilled owner expectations.”

As of March 2024, there were 5,381 data centers operating in the U.S.

A Bright Future

The importance of data centers to an organization’s operations cannot be overstated.

GPRS Market Segment Leader Kasey Kearcher recalled a conversation with a facility manager at a data center for a major bank in the Mountain Region. The bank has over 100 branches across multiple states and requires two data centers to service those facilities.

GPRS performed comprehensive utility locating and mapping services for one of the bank’s data centers. During this process, Kearcher inquired what would happen should the data center suffer a power outage.

“If they have a shut down, if that data center shuts down for any reason, it costs the bank half-a-million-dollars per minute,” Kearcher explained. “All the banking locations are reliant on this facility, so if there’s ever a utility line strike, or if they have a water line leak and that spills onto any of the equipment, that could be expensive and catastrophic.”

Despite questions about power usage and other challenges, the data center construction boom is only expected to continue.

Google has invested billions in data center expansion over the past few years, including its recent announcement that it will build a $1 billion data center campus in Kansas City, Missouri. Amazon paid $152 million to acquire 140 acres in Prince William County’s Data Center Opportunity Zone Overlay District and are exploring the possibility of construction data center locations there. And Microsoft is already building a data center campus in the area with plans for it to be up and running by mid-2024.

“The demand for data centers is expected to surge in the coming years as the world becomes increasingly interconnected,” The Birmingham Group’s President and CEO, Brian Binke, wrote in a blog post last fall. “With companies like Google, Amazon and Facebook leading the charge, data center construction will continue to thrive, supporting the digital infrastructure needed for a connected future.”

How Artificial Intelligence Can Aid the Construction Industry

In the realm of construction, AI plays a pivotal role in enhancing project management, Operations & Maintenance (O&M), and safety protocols.

Artificial Intelligence (AI) has seamlessly woven itself into the fabric of our daily life for years. And contrary to the apocalyptic scenarios of AI portrayed in popular fiction, current AI technologies such as Apple’s Siri and OpenAI’s ChatGPT are based on established machine learning models requiring continuous input from data scientists – meaning we’re still at least a few years away from robots taking over the world.

In the realm of construction, AI plays a pivotal role in enhancing project management, Operations & Maintenance (O&M), and safety protocols.

Boston, Massachusetts-based construction company Suffolk was recently featured in a Business Insider series exploring how AI is being used across different industries. In 2017, Suffolk appointed its first chief data officer, Jit Kee Chin, and invested in construction startups and used its own jobsites to test out potential solutions to safety-related problems.

Suffolk worked with NewMetrix, a startup based in Cambridge, Massachusetts, to develop a safety-solution-leveraging AI to digitize the process of safety observations and incident data gathering.

“The shift from manual and analogue to digital enabled us to collect data, and that’s the most important piece of all of this,” Suffolk’s National Director of Operational Excellence, Kelsey Gauger, told Business Insider. “It plays into our data strategy.”

NewMetrix then developed a predictive model that leverages AI to assign risk ratings to Suffolk job sites and predict the likelihood of an incident occurring on them. The model’s findings led Suffolk to change their key performance indicator (KPI) for jobsite safety: from a target of reducing the total number of on-site incidents to the number of safety observations carried out per workforce hours accumulated.

Suffolk saw a 25% improvement rate in their total recordable incident rates in the fiscal year following the implementation of this data-driven strategy. NewMetrix’s machine-learning model now accounts for 40 different factors correlated with safety outcomes on Suffolk job sites.

“One of the things that we’ve been able to do is actually flag at-risk projects, in addition to driving safety observations, so we can actually plug into that model all of this information and it can tell us ‘Here are the three jobs in your portfolio that are the most at risk,’” Gauger said.

Job Security

AI isn’t going to take over the world tomorrow, but many employees are concerned that it’s going to take their jobs away.

ResumeBuilder recently surveyed 750 business leaders at companies that currently use or plan to use AI in 2024:

  • 53% of the companies surveyed use AI, and 24% plan to start in 2024
  • 37% of the companies using AI say the technology replaced workers in 2023
  • 44% of companies surveyed say AI will lead to layoffs in 2024
  • 96% of companies hiring in 2024 say candidates will benefit from having AI skills
  • 83% say AI skill will help current employees retain their jobs

AI can’t steal jobs that were already open.

There were 413,000 open construction jobs on the last day of January 2024. That’s more unfilled positions than the same time in 2023, and near the record 454,000 vacancies that existed the previous November, according to data from the Bureau of Labor Statistics.

Henning Roedel, robotics lead for the innovation team at Redwood City, California-based DPR Construction, told Construction Dive in an article published last May that, “We don’t think about how to reduce our staff size, because we have enough backlog and work ahead of us that we need more people.”

“You need to flip the displacement question around because we currently don’t have enough people in our industry to meet the construction needs of society as it is,” Roedel continued.

While it’s not likely to replace a workforce anytime soon, AI does face other challenges as its champions look to integrate it into the construction industry. Many of these concerns aren’t industry-specific; questions about data privacy and technology cost arise no matter which sector is looking to introduce AI-driven solutions to its problems.

“Despite these challenges, the potential of AI in construction is immense,” American Management Services, Inc.’s Louis Mosca wrote last year in an article in Forbes Magazine. “As technology continues to evolve, we can only imagine how much more it could reshape the industry.”

Producers of AI-driven tools for the construction industry believe they are doing what has always been done: innovate to increase productivity, efficiency, and accuracy.

GPRS Combines AI with Field-Verified Data

GPRS utilizes artificial intelligence in conjunction with field-verified data to create accurate digital maps and models for use in AEC industries. While we believe in embracing innovative technologies, we complement those tools with our highly trained field staff and in-house Mapping and Modeling Department.

“At GPRS, the Mapping and Modeling Department creates accurate 3D tours, as-builts, intelligent 3D building information modeling (BIM) models, and geolocated utility maps that can be used in (conjunction with) AI to help project planning, design coordination, and project execution,” explained GPRS Mapping and Modeling Manager, Michelle Colella. “GPRS’ Mapping and Modeling Department uses AI natively in most of our work to automatically extract features and lines in a utility map, to analyze concrete reinforcement as-built, to quickly extract 3D modeled elements in a point cloud from laser scanning, and even to classify point clouds into their different functional elements like walls and floors.”

“All of the digital drawings and models we build can be used in AI-driven construction activities like clash detection, digital twins, or functional analysis of a structure, site plan, or mechanical system,” Colella concluded.
