Complete Building Services (CBS)

What Complete Building Services (CBS) does

Complete Building Services (CBS) is a privately held facilities services company headquartered in Washington, DC, founded in 1963 as the facilities management division of The Donohoe Companies, Inc. (established 1884). CBS provides integrated facilities management, operations and maintenance, HVAC service and repair, and energy management services delivered by an in-house workforce of facility managers, building engineers, mechanics, and corporate support staff. The company's stated footprint covers 55M+ square feet across 250+ client locations concentrated in the DC Metro and Mid-Atlantic region, serving federal, state, and local government agencies, commercial offices, military installations, laboratories, hotels, and institutional operations.

The company's technical foundation is a Direct Digital Control / open-protocol building automation platform that integrates with multiple CMMS platforms (Maximo, MicroMain, TRIRIGA, TMA, Facility Center, Archibus) and major controls vendors (Schneider Electric, Tridium Niagara, Trane, Honeywell, JCI), controlling over 55 million points in the DC-Metro area. A 60+-truck Mobile Maintenance Fleet is dispatched 24/7/365 from central headquarters to support both scheduled preventive maintenance and emergency response. Quality management is anchored in ISO 9001:2008-based guidelines, and the Energy Management Division, created in 1978, performs building automation, lighting controls, access controls, VFD installations, and remote monitoring.

Revenue is generated primarily through managed-services contracts and professional services engagements quoted on scope, building size, and service requirements rather than standardized pricing tiers. CBS holds GSA Schedule 03FAC (GS21F044GA) and GSA Building Maintenance and Operations Zone 1 (GS06Q16BQDU104) contracts that enable direct procurement by federal, state, and local government agencies, and holds Certified Business Enterprise, Local Business Enterprise, and Longtime Resident Business designations in the District of Columbia. Distribution is through direct enterprise sales led by a VP of Business Development, GSA contracting portals, and industry associations (ULI, IFMA, BOMA, BOMI). CBS does not publicly disclose revenue or financial performance.
