The average depth of the ocean floor bed is just over 12,000 feet. The deepest part of the ocean is called the Challenger Deep, and it’s estimated to run 35,867 feet deep. The world below our feet is vast, from the ocean to the soil beneath your favorite geraniums. One of the greatest challenges lies beneath the surface – navigating the complex network of underground utilities. Accidental damage to buried pipes, cables, or conduits can result in costly delays, safety hazards, and environmental concerns. To mitigate these risks, industry professionals rely on advanced technologies such as digital utility mapping software. Among these solutions, SiteMap® (patent pending), powered by GPRS, stands out as a comprehensive tool for interactive underground utility mapping.
Understanding Digital Utility Mapping
Digital utility mapping entails generating comprehensive maps and databases that illustrate the position, type, and attributes of underground utilities. This data is essential for the planning, designing, constructing, and maintaining of projects. Conventional utility mapping techniques, like manual surveys or paper-based documentation, can be laborious, imprecise, and error-prone. By employing advanced technologies such as Geographic Information Systems (GIS), Global Positioning Systems (GPS), and Ground Penetrating Radar (GPR), digital utility mapping offers accurate and current insights into subsurface infrastructure.
The History of Modern Underground Utility Mapping
The history of underground utility mapping can be traced back to the early 20th century when urbanization and industrialization spurred the need for more comprehensive infrastructure networks. Initially, utility mapping primarily relied on manual methods such as hand-drawn maps, paper records, and physical surveys to document the location of underground assets. However, these methods were labor-intensive, prone to errors, and lacked the ability to provide real-time updates. The advent of technologies such as Ground Penetrating Radar (GPR), electromagnetic induction, and Geographic Information Systems (GIS) in the latter half of the 20th century revolutionized utility mapping by enabling more accurate and efficient data collection and analysis.
These advancements paved the way for the development of digital utility mapping solutions, which utilize sophisticated sensors, GPS technology, and computer software to create detailed maps and databases of underground infrastructure. Today, underground utility mapping has become an integral part of construction, engineering, and urban planning projects, playing a vital role in ensuring the safety, efficiency, and sustainability of our built environment.
The process, as we know it today, can be accurate enough to support SUE (subsurface utility engineering) at level QL-B. While GPRS doesn’t offer SUE, how we use our technology can support surveyors in some ways.
The Development of SUE
Subsurface Utility Engineering (SUE) developed in the early 1980s as a solution to the shortcomings of conventional methods in managing subsurface utilities. Traditionally, projects were planned without comprehensive knowledge of underground utilities, leading to complications such as avoidable relocations, delays, and unforeseen encounters during construction. Engineers recognized the necessity for a more anticipatory approach and began integrating nascent technologies—specifically air/vacuum excavation and surface geophysics—to accurately identify subsurface utilities at the early stages of project planning.
Air/vacuum excavation was adopted as a safer substitute for traditional trenching, especially in highway construction where the danger of damaging utilities posed considerable safety risks. By revealing subsurface utilities before digging commenced, the likelihood of accidents, injuries, and property damage markedly decreased. This method quickly gained traction among progressive professionals in the highway sector.
Alongside, surface geophysics was introduced as an essential adjunct to overcome the limitations of vacuum excavation alone. Early SUE advocates, recognizing the challenges posed by relying solely on potentially inaccurate or incomplete utility records, stressed the importance of employing sophisticated surface geophysical tools to precisely locate subsurface utilities horizontally. Through the use of cutting-edge geophysical technologies, SUE innovators sought to deliver accurate and dependable data, thus enhancing decision-making in infrastructure development projects.
The Late 1980s
In the late 1980s, the significance of Subsurface Utility Engineering (SUE) began to resonate with highway engineers, marking a pivotal moment in its adoption. The Virginia Department of Transportation emerged as a trailblazer, becoming the first state agency to integrate SUE into its regular operations. Subsequently, its implementation spread to neighboring states such as Maryland, Delaware, and Pennsylvania, signifying a growing recognition of its benefits across the transportation sector.
Additional facets of SUE emerged, including surveying subsurface information, data management, and integration with clients' Computer-Aided Design and Drafting (CADD) systems or project plans. This expanded scope underscored the importance of SUE as a comprehensive service offering, encompassing not only utility identification but also data management and project coordination.
Furthermore, the late 1980s saw significant developments in the professionalization of SUE practices. Key initiatives included the sealing of deliverables and the procurement of professional liability insurance, which positioned SUE as a recognized professional service rather than merely a contractor service. These measures aimed to uphold industry standards, enhance accountability, and mitigate potential risks associated with utility-related projects.
In 1989, a pivotal moment occurred at the First Annual National Highway Utility Conference in Cleveland, where the term "Subsurface Utility Engineering" was introduced to a national audience as an umbrella term for the process formerly known as "Designating and Locating." This designation quickly gained traction and was abbreviated to "SUE," cementing its place as a foundational practice in infrastructure development and utility management.
