Laboratory Soil and Rock Testing Services

The contract requires the performance of physical and engineering property tests on soil and rock samples obtained from field borings to support the design of retaining structures. These tests are critical for determining material behavior under load, stability characteristics, and suitability for structural applications, ensuring engineering solutions are safe, durable, and compliant with geotechnical standards. The work is to be conducted under a subcontract relationship, with the scope aligned to the NAICS code 541380 for specialized engineering services, and is being managed by Caltrans District 2 in Redding, California. All testing must be performed in accordance with accepted industry practices to provide accurate data directly informing the structural design process. The contract was posted on May 29, 2026, and the location of performance remains unspecified, indicating that sample collection and testing may occur across multiple sites within California’s District 2 region. There is no set-aside designation or additional procurement restrictions listed, suggesting broad eligibility for qualified subcontractors. The project link provided leads to Caltrans' internal system for tracking infrastructure projects, and while no point of contact or physical address is included, the agency responsible is clearly identified as the California Department of Transportation. Deliverables are expected to include detailed laboratory reports that translate test results into actionable engineering parameters for retaining wall and slope stabilization systems.
