Protect Your Project from Hidden Risks with GPRS Utility Locating, Mapping, and Modeling

If you're managing environmental concerns during due diligence or suspect contamination, it's critical to understand the impact to soil, groundwater, or soil vapor while keeping your team safe and costs down. Your priority is to reduce risks during soil borings, vapor pin installation, and UST investigations.

GPRS utility locating identifies underground utilities and UST components, helping you clear soil borings, install vapor pins, drill safely, and avoid damage. Our custom utility CAD maps protect infrastructure, while conceptual site models (CSMs) reveal potential contaminant migration pathways and guide your next steps.

We provide a full suite of services, including utility locating, concrete scanning, video pipe inspection, and 3D laser scanning, tailored to your project needs to support safe sampling, hazard identification, and remediation planning.

Deliverables are uploaded to GPRS’ SiteMap^® GIS platform, giving you fast access to accurate data and insights to help you reduce risk, stay compliant, and make confident decisions.

Soil and Groundwater Sampling

Identifying safe boring locations is difficult when underground utilities are unknown or poorly mapped. Drilling without clearance can cause strikes, injuries, delays, and added costs. GPRS provides accurate maps of public and private utilities using utility locating and video pipe inspection. We clear drilling locations in advance to protect your team and infrastructure. Reliable utility data reduces risk, supports efficient sampling, and helps your team maintain safety while in the field.

Soil Vapor Assessment

Contaminants like petroleum and solvents can migrate as vapor, posing health risks. Installing vapor pins requires drilling through slabs, risking conduit strikes and damaging reinforcements, especially in buildings with little to no documentation. GPRS SIM-certified Project Managers use concrete scanning and utility locating to identify shallow utilities and reinforcement before drilling. We support vapor intrusion investigations with subsurface data, mapping, and modeling. You get accurate data that reduces disruption, prevents strikes, and supports compliance with health and safety regulations.

UST & LUST Locating and Mapping

Locating underground storage tanks is challenging when records are missing. Uncertainty around tank location or condition can lead to costly mistakes and regulatory issues. GPRS uses utility locating to safely locate orphaned, abandoned, or active UST systems. We provide CAD maps and conceptual site models to support remediation and compliance. Fast, accurate data helps you reduce risk, protect property value, and make informed decisions during due diligence.

Delineation and Remediation

Tracking contamination across soil, groundwater, or soil vapor can be complex. GPRS provides scalable solutions from utility locating, concrete scanning, video pipe inspection, as well as mapping and modeling, to meet the needs of your project. Precise data and efficient workflows help you save time, reduce costs, and make confident decisions that support reaching No Further Action (NFA) or regulatory closure.

CUSTOM SERVICE PLANS

Rather than send a rigid rate sheet to prospective clients, GPRS can create a customized service plan. We take into account our industry experience, national footprint, and operational/scheduling capacity to craft a customized plan just for you.

Scheduling

With one single point of contact for your company, GPRS can schedule underground utility locating, 3D laser scanning, concrete scanning, video pipe inspection, and void detection services for your site with a simple phone call. There is no need to call multiple service providers across a region or nationally. GPRS has Project Managers in every major market in the US and our single point of contact will simplify your scheduling process.

Pricing

GPRS understands that clear, understandable, and consistent pricing is a big deal. Our nationwide footprint allows us to streamline our costs on a nationwide basis. We are sure to craft a cost structure that makes sense for the scope of work. Rather than send a blanket rate sheet, we consultatively compose pricing plans for each project.

Approach

Every campus, site, and facility pose different challenges. Since our inception, GPRS has completed hundreds of thousands of projects and relies on that experience when crafting a site-specific plan for safety, scanning, and reporting. With the SIM Specification as our guide, we will craft an individualized approach to each and every project. We Intelligently Visualize The Built World^® from facility mapping to utility locating prior to excavation, and will perform the right service for your scope of work.

Mapping and modeling - GPRS - Ground Penetrating Radar

mapping & Modeling

GPRS improves project planning and communication by providing clear and understandable maps and models to help you Visualize The Built World^® and share your vision with subcontractors, designers, engineers, and others, easily.

GPRS delivers the most up-to-date, accurate and comprehensive site data possible in the format required for your project. We provide complimentary KMZ and PDF maps with every utility locate we perform. Our Mapping & Modeling Team can create a wide variety of customizable maps and models, from a simple GPS-enabled map of your utility locate, to highly-detailed 2D CAD drawings and 3D BIM models, depending on your needs.

AS BUILT DRAWINGS

Existing drawings don't always show the current conditions of a site. Drawings that are produced in the design phase of a project don't always reflect the exact location of the underground utilities and current as built site conditions. Renovations, repairs, and additions can all render as built drawings out of date. The GPRS Mapping & Modeling Team can deliver up-to-date as built drawings that reflect the actual vertical and horizontal position of underground facilities & features, and structural, architectural, and MEP site details.

2D MAPS & 3D MODELS

Utility locates, concrete scanning, and 3D laser scan data can be processed into up-to-date 2D maps and 3D models to ensure that your team has all the information you need to get the job done right. These maps and models provide an accurate record of utility locations and as-builts for project planning.

The GPRS Mapping & Modeling Team will deliver point cloud data, 2D CAD drawings, 3D BIM models, 3D meshes, TruViews, and virtual tours produced with the highest quality standards. We provide high-precision custom analysis and calculations such as dimensional callouts, tank calibration analysis, floor flatness and levelness analysis, deviation analysis, deformation analysis, volume calculations, wall plumb analysis, and more.

Maps, models, and analyses are produced and hosted for your use at any level of detail in a variety of formats such as Revit, AutoCAD, ReCap, Navisworks, Civil 3D, BIM360, A360, Bentley, Leica Cyclone, Cintoo, NavVis Ivion, and more. The GPRS Mapping & Modeling Team has optimized workflows for importing data, registration, creating maps and models, quality checks, and transferring data to clients. We deliver the data you need in the format you need to access up-to-date and accurate facility and infrastructure information.

SITEMAP^® MOBILE APP

When we conduct an underground utility locate, GPRS stores all subsurface infrastructure data in SiteMap^®, a secure digital platform that houses all your utility locate PDF and KMZ files. You can access your data from any laptop or mobile device and securely share it with your team. Within your files, you will find interactive subsurface maps, annotations, and more, where you can toggle layers and lines on or off to streamline information and communicate only the data you need. You can even measure site features and segment maps geographically to drill down to specific project points for prefabrication or excavation needs.
‍

GPRS Project Managers can complete multiple mobilizations to a jobsite – before, during and after construction – to record subsurface and as built data in real-time. The data captured can be tied together into living maps and models and saved into a database for reference.

How can GPRS can help you streamline your next project to Intelligently Visualize Your Built World^®?

One Call Program

GPRS exceeds industry performance when it comes to the accuracy of our utility locating. Our team of Project Managers can continue the support of your project by crafting a one-call program from when your project transitions to the O&M phase.

Public Property

Damage prevention is critical when excavating in a public right-of-way. Using the 811, call before you dig system, is an essential step to take when trying to avoid underground utility strikes. It's the law! GPRS is able to contract and perform one-call type utility locating for your underground assets.

Private Property

A utility locate on private property is not complete until a private utility locator like GPRS has been called to comprehensively locate the entire campus. GPRS can create a one-call type program for your facility or campus in the case that you have utilities that lie within public property.

Embedment

Our highly trained Project Managers have extensive experience locating conduits, rebar, cables, pipes, ducts, sleeves, and other hazards embedded in concrete slabs and other structures with ground penetrating radar technology. Cutting, coring, or drilling into these objects can cause damage to utilities and jeopardize the health and safety of workers on site.

GPRS Utility Locate and 3D Laser Scan for a Gas Station

Location: Brighton, Michigan

Task:

A Michigan gas station requested utility locate and as built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks. Accurate 2D utility locate maps, a 3D BIM model, and a conceptual site model (CSM) were created of the gas station, underground storage tank system, and surrounding utilities.

Problem:

The gas station lacked as built site information required for compliance with environmental regulations, essential to plan for site upgrades, and necessary to take prompt corrective action in the case of an emergency.
The client did not have an accurate conceptual site model (CSM) to understand and interpret contaminant fate and transport in the subsurface.

Solution:

GPRS Project Managers used state-of-the art equipment to perform ground penetrating radar (GPR), electromagnetic (EM) locating, video pipe inspection (VPI), leak detection, 3D laser scanning, and drone photogrammetry services at the gas station.
The GPRS Mapping & Modeling Team delivered accurate as built and utility location data in point cloud, 2D maps, 3D BIM model, and CSM formats, to help eliminate guesswork from decision making, and prevent time-consuming and dangerous mistakes and the costs associated with them.
The gas station received access to millimeter-accurate information to efficiently plan work and drill safely.
Locating underground storage tanks, including their depths, can help the station owner detect unusual fluctuations in fuel levels and assess any potential leak faster.
Detailed site maps can help to communicate the location of a leak, the most likely paths and extent of horizontal and vertical delineation, and to plan assessment and mitigation efforts.

Benefits:

Infrastructure location and mapping are vital before conducting any construction or subsurface work like soil boring, or coring concrete to drop vapor pins – to eliminate clashes and utility strikes and keep workers and the community safe.
Comprehensive site data is essential for the early detection and management of petroleum leaks at a gas station, to help minimize environmental damage and ensure the safety of employees and the surrounding community.
GPRS as built maps and models provide accurate information to avoid hitting a UST or system component, and to avoid a utility strike when sampling soil.
The GPRS SiteMap® mobile app securely stores utility data, geolocated and layered, and securely accessible for the station stakeholders to share with those who may need it.
The data GPRS collects can also be used to develop the utility portion of a conceptual site model (CSM) to visualize migration routes, communicate with stakeholders, make informed remediation decisions, and protect the team on site and the environment.
