About the company
ECS Mid-Atlantic LLC operates exclusively as a subcontractor on federal construction and engineering projects, delivering materials testing, asbestos surveys, and structural analysis services to prime contractors across the Department of Justice, General Services Administration, Department of the Navy, and Department of Defense Washington Headquarters Service. The vendor is a for-profit limited liability partnership headquartered in Fredericksburg, Virginia, with no prime contract vehicles and no direct federal contracting relationship — all four awards in the source are sub-awards to HDR Architecture Inc., BL Harbert International LLC, WDP & Associates Consulting Engineers Inc., and Vanar Eastern JV1 LLC.
ECS Mid-Atlantic's recent work centers on facility and infrastructure diagnostics. The vendor performed destructive testing for corridors 2 and 3 on a sub-award to HDR Architecture (September 2026), conducted materials testing on a Jefferson Dorm renovation project under BL Harbert International (August 2025), performed asbestos-containing materials surveying for an IRS Martinsburg MECC roof replacement under WDP & Associates (June 2025), and provided sampling and laboratory analysis of stockpiled soils for a B-7 galley concrete freezer pad project in Chesapeake, Virginia, under Vanar Eastern JV1 (October 2024). Combined obligated dollars across the four awards total $102 thousand, with awards spread across four distinct IDCs under different agencies and no concentration in customer or vehicle. Activity has been sporadic — one award in 2024, two in 2025, and one in 2026 — and the vendor carries no parent GWAC or BPA position. The two dominant work categories by award count are commercial and institutional building construction (2 awards) and engineering services (1 award), with a single historical-sites classification. ECS Mid-Atlantic's footprint reflects a specialized subcontractor role in federal facility diagnostics and materials analysis, with shallow federal penetration and no visible path to prime contracting or vehicle positioning.
