Subgrade Preparation and Soil Compaction

The contract titled Subgrade Preparation and Soil Compaction involves the excavation, inspection, and compaction of subgrade material beneath replacement concrete slabs to ensure long-term structural integrity and prevent future settlement. Work must be performed to precise engineering standards to guarantee proper soil density and load-bearing capacity, with all phases carefully monitored to meet required specifications. The scope requires thorough site evaluation, removal of unsuitable material, controlled backfilling, and mechanical compaction to achieve uniform stability under the new slabs. This subcontract is issued by the Office of Exposition Park in California, with performance located in Los Angeles. The solicitation was posted on May 2, 2026, and responses are due by May 28, 2026, under NAICS code 237990 for other heavy and civil engineering construction. There is no set-aside designation specified, and while the point of contact and full address details are omitted, the work must be completed at the designated site in Los Angeles to support infrastructure improvements tied to the agency’s facilities. Contractors must be prepared to demonstrate compliance with subsurface engineering requirements and quality assurance protocols throughout all phases of the project.
