How We Use Laser Scanning Equipment & Data Platforms To Create 2D & 3D Maps & Models

GPRS/TruePoint 3D Laser Scanning Services make hyper-accurate as-builts, 2D CAD drawings, 3D BIM models and meshes, and interactive 3D walkthrough tours a reality for a wide variety of construction-related industries through our photogrammetry, LiDAR scanning, and visualization solutions.

How Much Does It Cost To Rent Or Buy Utility Locating Equipment?

Locating public and private underground utilities is vital to the safety of any job requiring excavation and could be the difference between finishing a construction or renovation project on time and on budget, or suffering the huge cost overruns and downtime of damage caused by a utility strike.

What Do the Utility Marking Colors Mean?

Markings like these are everywhere, especially around new construction. What do these flags and spray-painted markings mean? If you are wondering the answer to these questions, then you’re in the right place.

What Is The NavVis VLX Mobile Mapping System & How Does It Work?

The NavVis VLX is a mobile mapping system designed for 3D laser scanning, providing accurate as-built documentation of buildings and construction sites. Built for architecture, engineering and construction (AEC) applications, it produces accurate point clouds, digital twins, scan-to-BIM models and CAD 2D drawings.

Monday Night Football at Gillette Stadium Featured The Famous Group’s ‘Flying Razor’ Mixed Reality Experience

During the Bears vs. Patriots Monday Night Football game at Gillette Stadium that aired on October 24, 2022, a 45-second virtual reality video campaign promoted the Gillette Exfoliating Bar Razor.

Non-destructive Concrete Structural Analysis Could Mitigate Liability In Florida Condominiums

Structural engineers, architects, and concrete restoration companies in Florida have a very big job in front of them. The engineers and architects have to certify the structural integrity of every high-rise condominium building in the state by providing “Milestone Inspections” that must be completed by Dec. of 2024

GPRS Can Assess Damage After a Natural Disaster

From hurricanes and tropical storms to earthquakes and tornadoes, natural disasters cause extensive damage to buildings and infrastructure. The effects are immediate. Buildings and sites can be full of potential safety hazards – buildings shift, structural integrity is compromised, pipes are damaged, and concrete conce

How Does Photogrammetry Work?

Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images.

3D Scanning Missing From National BIM Standards

If you’re in the architecture, design, real estate, or construction engineering industries, you may have seen the recent update from NIBS (The National Institute of Building Sciences) regarding their ongoing initiative to create a nationwide standard for BIM models in architecture and design.

3D Laser Scanning for Building Renovations

Field verification of an existing building is an incredibly time-consuming process with huge potential for inaccuracies. By using a 3D laser scanner, you can capture precise as-built data, including all details of the layout and materials, and take it back to your office for evaluation.

What is LiDAR and How Does It Work?

LiDAR, short for light detection and ranging, is a remote sensing technology that uses light in the form of a pulsed laser to measure distances to a target. A LiDAR sensor sends out beams of laser light in all directions and then measures how long it takes for them tore turn back to the sensor.

Rent, Buy, Or Hire? A Comparison Of Leak Detection Equipment & Services For Large Projects & Municipalities

Under groundwater leaks are a major concern in the commercial/industrial plumbing and construction industries. Not only are they huge budget busters, hidden leak scan jeopardize commercial and municipal infrastructure in unanticipated ways.

What Is Scan To 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. It’s more than just a model. It’s a process of collecting and managing data throughout a building’s entire life cycle.

Architectural Laser Scanning Minimizes Risks And Reduces Costs

Some architects consider the documentation of existing conditions to be an added expense. However, many have come to realize that accurate as-built documentation ultimately saves them time and money. Eliminating one change order related to unknown existing conditions can more than pay for the cost of the survey.

Measure Once, Cut Once: The Two Hidden Costs Of Not Measuring With 3D Laser Scanning Services

$177.5 billion per year and two full workdays every week are lost to fixing mistakes in the construction industry. How much could you save?

What Are the Benefits to Laser Scanning in Color?

The default for construction-grade 3D laser scanning is intensity or greyscale. This refers to the coloring of the point cloud inside of software such as Revit, Recap, and TruViews. Data can be viewed in RGB, intensity, or greyscale.

Reduce Water Loss, Save Money with Acoustic Leak Detection

In Los Angeles, California, the problem of old, worn down, leaky cast iron and plastic pipes cause staggering amounts of water loss: an average of between 16 million and 36 million gallons every day. These 100-year-old pipes are in desperate need of refurbishing and replacement. With millions of gallons lost each day,

3D Laser Scanning Explained

3D laser scanning is a construction, engineering, and architectural tool often used to document the existing conditions (as-builts) of any structure. 3D laser scanners use LiDAR (light detection and ranging) to measure and record precise locations and distances, ultimately producing a point cloud file.

The Intelligent Art of Locating

Field Notes on Subsurface Investigation Methodology: Savvy (noun): having or showing perception, comprehension, or shrewdness especially in practical matters, practical know-how [Merriam-Webster Dictionary]

Solving The Infinite Problem of Small Leaks With Annual VPI Inspections

One of the reasons we at GPRS say “What’s underneath matters” is because throughout the U.S., over 2.5 trillion gallons of water are lost to pipe defects annually.
