The U.S. Army Corps of Engineers Sacramento District is seeking multiple small business offers for Quality Assurance laboratory testing services across five regions: Utah, Nevada, Northern California, California Bay Area & Stockton-Modesto, and Central Coast & Southern Valley. The procurement will establish firm-fixed-price Blanket Purchase Agreements with a five-year ordering period, requiring contractors to provide all personnel, equipment, and materials for field and lab testing of materials like soil, concrete, and asphalt. Offerors must indicate which regions they wish to serve and provide 100% pricing for all tests in that region’s price list, with subcontracting allowed for tests not self-performed. Contractors must maintain active validation through the USACE Material Testing Center to receive orders. No budget amount is specified, and the location for performance is the designated regions within the Sacramento District’s area of responsibility.
