About the company
S.J. Amoroso Construction Co., LLC, a for-profit limited liability company based in San Mateo, California, operates as a prime contractor on heavy civil and medical-facility construction projects for the Department of Veterans Affairs and the General Services Administration, with no subcontractor activity and no SBA set-aside certifications. The vendor competes on full-and-open federal construction contracts and is structured as a subsidiary of S.j. Amoroso Construction CO. Holdings, LLC.
The vendor's portfolio concentrates almost exclusively on Veterans Affairs medical-center construction and renovation work. The Department of Veterans Affairs Office of Construction and Facilities Management holds seven awards worth $718.2 million in combined potential value, accounting for 68% of all awarded dollars across the vendor's footprint. Within that VA concentration, S.J. Amoroso has delivered a $179.9 million design-build contract for kitchen revision modifications and Phase A construction at the Livermore Veterans Affairs Medical Center (completion scheduled August 2, 2027), a $69.6 million firm fixed-price definitive contract for construction of a new boiler plant at the VA Medical Center in West Los Angeles (ultimate completion April 21, 2027), and a $9.9 million renovation contract for a Catheterization Laboratory and Hybrid Operating Room Suite at the VA Palo Alto Health Care System. Beyond VA work, the vendor holds two awards from the National Aeronautics and Space Administration Ames Research Center totaling $40.1 million, six Department of the Army awards, and sixteen awards from the General Services Administration Public Buildings Service. Recent activity includes a $10,000 stipend from the VA Office of Construction and Facilities Management for Phase II proposal participation in the Sepulveda Ambulatory Care Center design-build project (July 2026).
The vendor's federal construction work falls under primary NAICS 236220 (Commercial and Institutional Building Construction). Across fifty-two total awards spanning from 1987 to the present, the vendor has accumulated $1.06 billion in combined potential value, with $1.07 billion obligated. Activity has been episodic rather than continuous — only five awards in the past five years — but dollar magnitude is large: three awards reaching ultimate completion within the next twenty-four months carry combined potential value of $249.5 million, representing significant recompete exposure. The vendor operates entirely as a prime (100% of the award count) with zero subcontractor engagement on SCI-reportable service contracts; across SCI-reportable federal service contracts captured from FY2025, the vendor shows $18.1 million in invoiced revenue and 8.4 FTEs delivered to the federal government. This SCI activity is a narrow slice of the vendor's federal work and does not reflect the bulk of the vendor's construction contract delivery, which falls outside the SCI reporting threshold.
