Silva Cost Consulting, Inc.

Silva Cost Consulting, Inc. (doing business as Silva Cost Consulting) is a minority-owned, Hispanic American-owned for-profit Subchapter S corporation operating exclusively as a subcontractor on federal facilities design and cost estimation work. The vendor holds DOT Certified Disadvantaged Business Enterprise (DBE) status and operates as a tax-exempt corporate entity; all ten awards in the source record are subcontract task orders, with zero prime contract or IDV positions.

Silva Cost Consulting delivers cost estimating and cost consulting services across architectural and facilities engineering projects, primarily for General Services Administration Public Buildings Service (GSA PBS) Region 9 facilities. Representative work includes cost estimating for electrical vehicle supply equipment design at the Phillip Burton Federal Building in San Francisco (September 2024), a rooftop café feasibility study at the Pelosi Federal Building (October 2023), a glazing leak study at 650 Capitol Mall in Sacramento (August 2023), an ice vehicle gate replacement at the same Sacramento location (August 2022), elevator modernization design services at the National Archives and Records Administration facility in San Bruno (March 2022), and a feasibility study for the Ronald V. Dellums Federal Building in Oakland (July 2021, subsequently amended with COVID vaccine mandate clauses per Executive Order 14042). All subcontract work flows through a single prime contractor, Interactive Resources, Inc., which holds the parent Indefinite Delivery Contract 47PK1720D0008 that feeds all ten task orders.

Customer concentration is extreme and narrow: GSA PBS Region 9 accounts for 8 of 10 awards (80% by count), with the Federal Trade Commission and Immigration and Customs Enforcement each holding a single award. Combined potential value across all ten subcontract awards is $88 thousand. Activity has declined since 2020 (three awards that year to one in 2024), with the most recent award dated September 2024. All work is categorized under NAICS 541512 (Architectural Services). Silva Cost Consulting operates entirely within the Interactive Resources prime relationship and has not pursued, held, or been awarded any independent prime contracts, IDVs, GWACs, or agency-wide vehicles. The vendor's federal footprint is confined to GSA Region 9 facilities cost estimation in Northern California, with no evidence of work outside that geography or outside the Region 9 PBS customer set.
