About Williams Building Company, Inc.
Williams Building Company, Inc., a Service-Disabled Veteran-Owned Small Business (SDVOSB) headquartered in Hyannis, Massachusetts, serves as a prime contractor exclusively (100% of awards) delivering healthcare facility construction, renovation, and infrastructure upgrade services to the federal government, with dominant concentration at the Department of Veterans Affairs. The company holds SBA certifications for both VOSB and SDVOSB status, expiring August 22, 2027, and operates as a Subchapter S corporation under primary NAICS 236220 (Commercial and Institutional Building Construction).
Williams Building's customer footprint is heavily concentrated with the VA. The top five funding agencies account for 90% of recent awards by count and 92% by potential value, dominated overwhelmingly by VISN 1 (Veterans Integrated Service Network 1) with 157 awards worth $544.1 million combined potential value. The Department of State's Bureau of Overseas Building Operations places the second-largest dollar volume at $2.16 billion across 20 awards, driven by large single construction contracts rather than volume — indicating a two-tier customer profile: the VA as a high-volume ordering partner across many small to mid-size task orders, and State as an anchor for mega-projects. Three awards from the Department of Veterans Affairs Technology Acquisition Center carry $1.01 billion in combined potential value, representing the newly awarded $1 billion VISN 1 Construction MATOC (December 16, 2025) and related large IDIQs. The Department of the Navy's Naval Facilities Engineering Command and VISN 8 round out the top five by dollars, with $401.8 million and $250 million respectively.
Williams Building holds three major indefinite delivery contracts anchoring its federal footprint. The newly awarded VISN 1 Construction MATOC (December 16, 2025) carries a $1 billion ceiling through December 15, 2030, set-aside exclusively for SDVOSB and covering construction, repair, and alteration work across VA facilities in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. An October 9, 2024 VISN 1 Construction MATOC ($100 million ceiling through November 11, 2029) serves the same geographic footprint under SDVOSB set-aside with recent task-order activity including a $93,786 sidewalk repair delivery order (March 27, 2026) and a $2,000 minimum-guarantee order (September 10, 2024). A VISN 8 IDC ($250 million ceiling through July 12, 2023) supports construction services in central Florida. Across the legacy parent vehicles in the source data, the VISN 1 and 3 Construction 2013–2018 contract generated 54 task orders worth $92.7 million combined, and three other IDCs (36C24118D0105, VA241C1313, and VA24313D0152) carried 89 task orders worth $157.2 million combined. Recent concrete work includes a $7.965 million firm-fixed-price design-build for CT imaging equipment site preparation at Boston VA Medical Center (July 1, 2025), a $2.93 million design-build replacement of an electrophysiology laboratory at West Roxbury (May 15, 2024), a $2.3 million catheterization laboratory site preparation design-build at VA Medical Center West Roxbury (May 27, 2026, under total small business set-aside), and a $2.31 million PET-CT site preparation design-build at Jamaica Plain (February 29, 2024, SDVOSB set-aside).
Williams Building's activity trajectory shows volatility but recent contraction. Awards per year tracked at five awards in 2022, ten in 2023, five in 2024, three in 2025, and four in 2026 year-to-date. The recompete cliff is minimal: only five awards with ultimate completion in the next twenty-four months carry combined potential value of $13.8 million, indicating limited near-term recompete exposure relative to the company's $4.73 billion combined potential value across 227 total awards. On SCI-reportable service contracts, the company invoiced $20.7 million in FY2024 across 34.2 FTEs at the contract level, with substantially zero SCI activity in FY2022 and FY2023 — the rise in FY2024 reflects the recently awarded large design-build and site-preparation contracts that crossed the $150,000 reporting threshold. Across SCI prime records, median government-paid rates run around $361.28/hr, with senior labor pricing reaching the 90th percentile at $4,207.50/hr and base labor at the 10th percentile around $123.77/hr. Williams Building subcontracts approximately 13% of contractor hours on average across SCI-reportable prime contracts, engaging 26 named subcontractors — indicating the company performs the bulk of delivery in-house while using subs for specialized labor such as security system installation, electrical work, and facility-specific technical services. The company operates exclusively as a prime; it reports zero subcontractor awards, making it a prime-only federal contractor with a feeder posture primarily to the VA's regional healthcare system rather than to larger integrators.
