The intent of this contract is to install a 7’ wide by 14’ long by 6” thick concrete slab on grade for future use by the Refuge. The concrete slab will be used as a UTV washing station but on occasion it would be used to wash an 8,000-12,000 lb skid-steer.

Material Specifications

Material submittals shall be provided to the Government for approval, prior to installation.

The 7’ by 14’ by 6-inch-thick reinforced concrete slab on grade shall have a compressive strength of at least 4,000 pounds per square inch (psi) at 28 days, and shall be reinforced with #4 rebar, space at a minimum of 16 inches O.C (On Center).

Task 1 – Concrete Pad - Installation Requirements

Prior to the concrete slab installation, the existing ground shall be graded and compacted. Photos and/or inspection of compaction will be required. Contractor is responsible for ensuring acceptable subgrade compaction. Contracting Officer Representative (COR) retains the right to reject the subgrade based on perceived moisture and compaction deficiencies.

Pre-compacted Moisture content and density of native earth.

Additional Bid Option Item B:

Post-compacted moisture content and density of native earth, prior to placement of subgrade material.

Additional Bid Option Item C:

a Minimum of 2 concrete cylinders, compression strength testing.
