Interbay Building Services, Inc.

Interbay Building Services, Inc., a for-profit construction and building-services contractor, operates exclusively as a subcontractor on federal facility renovation and repair projects, with all five recent awards placed under prime contractors on military construction work.

The vendor's award footprint spans five subcontracts obligated at $1.5 million combined across a three-year window (June 2023 to March 2026). Work centers on concrete repairs, metal canopy installation, dampproofing, fluid-applied membranes, spray foam, joint sealants, and related building envelope and finishing services — classified primarily under Commercial and Institutional Building Construction (NAICS 236220, three awards), with secondary work in flooring and other building finishing trades. Recent representative work includes a March 2026 subcontract with RQ Construction for dorm renovation and sitework (joint sealants, fluid-applied flooring, waterproofing, and spalling repairs) at Hurlburt Field, Florida; an October 2024 subcontract with RQ Construction for dampproofing and air-barrier work on a fitness center construction project (P832); and a June 2024 subcontract with the Pacwest-Korte joint venture for concrete work and metal canopy installation on a Building 603 renovation.

Customer concentration spreads across four distinct federal agencies, all military branches and commands. The Department of the Navy Installations Command and the Department of the Navy Naval Facilities Engineering Command together account for three of five awards; the Department of the Army Corps of Engineers Headquarters Military Programs and the Department of the Air Force Special Operations Command each placed one award. Interbay subcontracts to three named primes — RQ Construction (two awards), the Pacwest-Korte joint venture (two awards), and Korte Construction Company (one award) — on vehicle-backed construction contracts including the Southeast Area of Responsibility Multiple Award Construction Contract, the Design Build MATOC for Texas, Louisiana, Mississippi, and Tennessee, and the South Alabama Region MATOC. The vendor does not hold direct prime positions on any federal IDIQs, GWACs, or agency-wide vehicles and competes exclusively through subcontract placement on military facilities-engineering work.
