GPRS PROVIDES COMPREHENSIVE DIGITAL UTILITY MAPS FOR ANY SITE NATIONWIDE
99.8% ACCURACY RATE
“GPRS ensured safe drilling areas in over 150. Locations through very congested floor slabs. The accuracy of the information provided was remarkably sound.”
- Mike Keith
Senior Project Superintendent, Turner Construction Company
"Our team was more effective and efficient because of SiteMap, allowing us to provide better results from more informed decision-making."
- Alexander Valigosky
Project Environmental Scientist, Arcadis
“GPRS is a valuable partner for us to deliver the best results for our customers. One area of safety that we are very focused on is preventing underground utility damage and GPRS has provided us with scanning features that allow us to see below the dirt, below the Earth, and therefore prevent potential safety occurrences”
- Aaron Seymour

Private Utility Locating Services
PRIVATE UTILITY LOCATING SERVICES
65% of on-site utilities on almost all sites are private. 811 One Call services cannot locate them for you. GPRS provides comprehensive digital utility maps for every utility on site – public and private – including depths, and can export your utility data into a variety of deliverables to give you seamless communication and collaboration on any project.

DELIVERABLES & AS-BUILT CREATION
Every GPRS customer receives a complimentary SiteMap® Personal subscription, where you receive deliverables that can span the entire building life cycle: from construction-grade 3D BIM models to 99.8% accurate utility locating and GPR concrete imaging, to NASSCO-certified Video Pipe Inspection Reports, CAD drawings, conceptual site models(CSM), rectified 3D photogrammetry via ProCap, WalkThru 3D virtual tours, and more.
Directional Drilling Image
DIRECTIONAL DRILLING CLEARANCE SERVICES
Need to install fiber or telecom lines safely? GPRS can give you the accurate information you need to avoid striking existing underground utilities and creating dangerous cross bores that risk utility infrastructure and community safety. Pre and post-installation inspections can capture accurate existing conditions before you drill, and verify the safety of your work upon completion.
Environmental Due Diligence
ENVIRONMENTAL DUE DILIGENCE, SOIL BORING CLEARANCES & CSM
GPRS assists in soil borings and testing in Phase I and Phase II Environmental Site Assessments (ESAs), for due diligence before a sale or when tracking potential contamination for regulatory concerns. Our 99.8% accurate utility maps illustrate preferential pathways, and with the addition of 3D services, can be used to provide a conceptual site model (CSM) for 3D site visualization.

ONE CALL LOCATING SERVICES
Calling 811 is the law. One Call connects you with public utility contractors who can provide you with the location of all public utilities near your excavation. However, those contractors cannot locate private utility lines, nor do they provide depths for public utility lines. GPRS can locate both private and public utilities, provide accurate field markings, and complimentary digital utility maps of your complete utility infrastructure.
UST Locating
UST LOCATING
Finding underground storage tanks (USTs) on site is crucial to remediating risk before you dig. Abandoned tanks and lines are found and mapped by GPRS’ SIM-certified Project Managers, and the data can be tailored to meet your needs: from a comprehensive, layered map toa full 3D conceptual site model (CSM) for risk mitigation and recordkeeping.

///DIFFERENCE BETWEEN PRIVATE LOCATING & ONE CALL

Private Locating Illustration
PRIVATE LOCATING
Private utilities are those which extend beyond service meters or are not maintained by a public utility company. Examples of private utility lines include electrical feeders and gas mains running to facilities. They may also include lines running to and from substations, industrial & manufacturing facilities, and refineries. These lines are not subject to 811 One Call public utility locating services and must be found by a private utility locating company like GPRS.
811 Responsibility Illustration
ONE CALL
Federal law mandates that anyone who needs to dig must call 811 so that their publicly maintained utilities can be located by a utility locator before breaking ground. Public utilities are determined by the utility companies and can usually include anything before you get to a utility meter. It is important to note that 60-65% of all underground utilities on any site are likely private, not public, so it is vital to hire a utility locator that can both verify public lines and locate private ones before you dig.
