This is a Statement of Work (SOW) for gravel delivery at Stillwater National Wildlife Refuge in Fallon, Nevada. The US Fish and Wildlife Service requires approximately 16,000 tons of Type 2 Class B base course aggregate to resurface 6.25 miles of Hunter Road, with a maximum 24-foot-wide roadway constructed in a 6-inch lift. The project requires delivering crushed stone with angular shapes, no rounded surfaces, and a plasticity index of 6 or less, to be dumped directly onto the roadway.
Performance parameters include mobilization within 30 days of award, with work to be completed between March 1 and June 30, 2026. Deliveries are restricted to Tuesday through Friday, between 07:00 and 15:00, with a minimum of 580 cubic yards per day and 15-30 minute intervals between loads.
