About MSS Services, Inc.
MSS Services, Inc., a minority-owned, self-certified small disadvantaged business based in Frederick, Maryland, operates as a construction inspection, facilities engineering, and project management services prime contractor to federal civilian agencies, with no subcontractor activity and 100% of its 308 recent awards placed as a prime. The company is Asian-Pacific American owned and competes predominantly full-and-open rather than under set-aside vehicles, though several awards carry Total Small Business designations.
MSS Services' customer base concentrates in federal real-estate and infrastructure operations. The top five customers by award count account for 56% of recent awards and include the Army Corps of Engineers Baltimore District (50 awards, $28.5 million combined potential value), the GSA National Capital Region Public Buildings Service (42 awards, $33.6 million), the Department of Energy Western Area Power Administration (31 awards, $16 million), the Veterans Health Administration Veterans Integrated Service Network 5 (26 awards, $19.2 million), and the Army Corps of Engineers Norfolk District (24 awards, $5.1 million). The two rankings diverge slightly: GSA's dollar share edges Army Baltimore on potential value, but Army Baltimore leads by award count — a pattern consistent with GSA issuing fewer, larger delivery orders while Army places more frequent smaller calls. Across the 308-award portfolio spanning 30 customer agencies, GSA and Army Baltimore represent the highest leverage for both volume and dollars.
MSS Services holds primary vehicle positions on the GSA Multiple Award Schedule (61 task orders, $44.2 million combined potential value) and several Army Corps of Engineers IDICs, including W912DS10D0005 (21 task orders, $11.9 million), W912DR08D0018 (23 task orders, $5.2 million), and W9123608A0005 (24 task orders, $5.1 million). Most recently, MSS Services secured a $9 million single-award indefinite-delivery BPA with WAPA for construction inspection services across four regional areas (Upper Great Plains, Rocky Mountain, Desert Southwest, Sierra Nevada) running through April 2031. Representative recent work includes a $258 thousand Total Small Business delivery order with WAPA for electrical engineering technical support in the Desert Southwest Region (September 2024), a $704 thousand Coast Guard delivery order for electrical engineering support services in Cleveland (August 2023, extended through June 2027), and a $28 thousand BPA call from WAPA for PMOC dispatch remodel inspection services in Loveland, Colorado (June 2026).
Capability framing centers on construction quality management, construction inspection oversight, facilities engineering support, and project management — NAICS codes cluster around Commercial and Institutional Building Construction (108 awards), Engineering Services (64 awards), and Facilities Support Services (52 awards), with PSC patterns dominated by Support-Professional/Other (129 awards) and Engineering/Technical (48 awards) categories. Activity was flat to declining in 2021–2024 (four awards in 2021 declining to one award each in 2022, 2023, and 2024), with a recent uptick of two awards in 2026. The recompete cliff is minimal — only one award ($704 thousand) faces ultimate completion within the next twenty-four months. On SCI-reportable federal service contracts, MSS Services invoiced $4.3 million across FY2022–FY2024 (roughly $1.3 million in FY2022, $1.4 million in FY2023, and $1.6 million in FY2024), delivering approximately 6.4 to 6.9 FTEs per fiscal year. Government-paid hourly rates on those contracts ran a median of $106.67/hr, with rates spanning from $101.86/hr at the 10th percentile to $154.75/hr at the 90th percentile, and the vendor self-performed 100% of reported hours with no subcontractor engagement.
