Materials Acceptance Testing and Independent Assurance Services

The City of Corcoran requests proposals from certified materials testing laboratories to provide materials sampling, inspection, testing, and independent assurance services for two federally funded transportation projects in Corcoran, California. The scope includes Category A (Acceptance Testing) and Category B (Independent Assurance), which covers independent verification of the acceptance testing program. Only onshore USA organizations are eligible, and firms may submit for Category A, Category B, or both, though a single firm will not receive awards for both categories. The Independent Assurance consultant must be a different firm from the acceptance testing entity. Consultants must secure required California workers' compensation, commercial general liability, professional liability, and comprehensive automobile liability insurance coverages. A pre-bid teleconference occurs on October 14, 2026. Applicants must submit proposals by Monday, October 26, 2026, at 10:00 a.m. Submissions require one unbound original, two bound copies, and a USB drive, or an electronic single searchable PDF emailed to [email protected]. Fee schedules and cost proposals must be delivered in hard copy in a separate sealed envelope directly to the City Clerk's Office by the deadline.
