About this file
This document is a Questions and Answers (Q&A) file for a concrete pad installation project at the Guadalupe-Nipomo Dunes National Wildlife Refuge in California. The federal contract opportunity (Solicitation Number 140FC125Q0015) involves constructing a concrete slab with specific technical requirements, including a minimum 90% subgrade compaction, #4 rebar reinforcement at 16 inches on center, and 4000 PSI concrete strength. The slab will be flush with existing grade and used to support heavy equipment like an 8,000-12,000 lb skid steer.
Key project details include utility locates being required, no city permitting needed, and no additional environmental or fire safety procedures beyond the scope of work. The Contracting Officer Representative (COR) will be on-site and responsible for testing, and the government will provide testing services. The total estimated project cost is below $10,000, and no bid security is required. The project scope is limited strictly to the concrete slab installation, with no utility work, anchoring, tank, or pressure washer installation included.

Slab shall be flush to existing grade; excess material will need to remove to accommodate for forms, it shall be backfilled, compacted and flushed to existing ground and new concrete slab.
How much over excavation will be required for the slab?
