About the company
Diamond - S Polished Concrete, Inc. is a woman-owned small business based in Spokane, Washington that performs concrete floor polishing, grinding, and restoration work as a subcontractor on federal building construction and renovation projects. The vendor operates exclusively in a subcontractor role and holds no prime federal contracts.
All four of Diamond - S Polished Concrete's recent federal awards span a single customer, the Army Corps of Engineers Engineering District Seattle, across 2023. The vendor subcontracts to International Towers LLC on warehouse construction, repair, and renovation work. Representative sub-awards include a July 2023 project for diamond grinding and polishing floors and restoration of control joints at an unnamed warehouse (with a funding correction in the amount of $1,047,140), a second July 2023 demolition, repair, and construction award for the same scope, and two November 2023 modifications — one adding funding for concrete floor polishing and a second for furnish-and-install mechanical and plumbing equipment (AHU, terminal units, chillers, boilers, exhaust fans, expansion tanks, louvers, pumps, and controls) at DLA Richmond Warehouse. Combined obligated dollars across all four awards total $5.2 million.
Activity ended in late 2023. The vendor has not received a new federal award in the source data since November 2023, indicating no active prime or sub recompete exposure within the visible window. Diamond - S Polished Concrete's footprint is entirely specialized and narrow — concrete finishing and polishing for federal facility construction and renovation work routed through a single prime relationship and customer agency.
