Ground Penetrating Radar Systems, LLC

Ground Penetrating Radar Systems, LLC (doing business as Gprs), a limited liability company based in Maumee, Ohio, delivers ground penetrating radar, utility location, subsurface surveying, and leak detection services to federal agencies as both a prime contractor (36% of recent awards) and as a subcontractor to larger engineering and construction firms (64% of awards). The vendor operates in full-and-open competition with no set-aside designations across its federal footprint.

Gprs specializes in concrete utility-locating and subsurface-assessment work grounded in geophysical surveying technology. Prime awards center on emergency facility diagnostics: a $12,200 firm-fixed-price purchase order from Veterans Integrated Service Network 4 in August 2026 to conduct LiDAR services to pinpoint a water leak at Altoona VA Medical Center; a $7,200 Air National Guard purchase order (August–September 2023) to locate a critical water utilities leak estimated at 20,000 to 100,000 gallons per day lost daily using specialized sonar equipment; and a $15,000 Federal Correctional Institution Herlong purchase order (August–September 2022) for hot water loop leak detection. Smaller-volume prime work includes ground-penetrating radar measurement services and sewer mapping at VA healthcare systems. The top NAICS category across the portfolio is Geophysical Surveying and Mapping Services (19 awards), followed by Remediation Services (13 awards) and Heavy and Civil Engineering Construction (10 awards).

Customer concentration is fragmented across federal facility operators and environmental remediation programs. The Department of the Navy Naval Facilities Engineering Command leads by award count (14 awards, $19 thousand combined potential value), but customer concentration by potential value shows the Veterans Affairs health system (Veterans Integrated Service Network 12, $16 thousand), Federal Correctional Institution Herlong ($15 thousand), and Veterans Integrated Service Network 4 ($12 thousand) rounding out the top tier. Across the portfolio's 28 distinct customer agencies, no single customer exceeds 24% of awards by count. Gprs places task orders against the Army Corps of Engineers' Indefinite Delivery Contract W912QR23D0011 (5 task orders), the EPA Remedial Acquisition Framework for Design and Engineering Services (4 task orders), and the Southeast Area of Responsibility Multiple Award Construction Contract (3 task orders).

As a subcontractor, Gprs delivers utility location and geophysical surveying services beneath larger prime contractors including AECOM Technical Services, Ch2M Hill, RQ Construction, Clark Construction Group, Noreas Environmental Services, and Weston-Techlaw JV. Sub work spans remedial investigation and feasibility studies (AECOM and Ch2M Hill on PFAS and Superfund site assessments), utility clearance and locating on construction projects (RQ Construction and Clark Construction on Navy facility repairs and relocation work), and CCTV pipe inspection on base infrastructure projects. Service Contract Inventory reporting shows minimal SCI-reportable activity: 0.8 FTEs delivered in FY2024 and zero FTEs in FY2025 across eight SCI records, all in the subcontractor role, indicating that Gprs's federal work is predominantly captured as task-order or micro-purchase activity below the $150,000 SCI reporting threshold.

Activity has remained relatively flat across the last five years (8 awards in 2022, declining to 5 in 2023, then oscillating between 7 and 10 through 2026). Combined potential value across all 59 awards sits at $140 thousand, though combined dollars obligated ($1.2 million) substantially exceeds the potential value, suggesting task-order modifications and augmentations.
