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.

Our job is to Intelligently Visualize The Built World® for you. We provide comprehensive above & below-ground facility and infrastructure mapping for the construction, facility management, engineering, architectural, manufacturing, and related industries.

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.

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.

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.

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.

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.
