Biso maintenance to sale pine trail

The National Park Service is procuring approximately 312 tons of crusher run limestone aggregate for trail maintenance at Big South Fork National River and Recreation Area's Salt Pine Ridge Horse Trail in Tennessee. The Department of the Interior's National Park Service Southeast Region seeks delivery of these materials to two designated stockpile locations (West Entrance Stockpile and Burke Field Stockpile) with approximately 156 tons delivered to each site. The limestone aggregate must meet specific technical specifications including being a well-graded mixture of crushed stone and fines that passes a 2-inch screen and is free of excess dirt and organic material. The government will evaluate offers based on technical capability, price, and past performance, with technical and past performance combined being approximately equal to cost in importance. Vendor questions are due by September 4, 2025 at 12:00 PM EST, and all proposals must be submitted electronically by September 11, 2025 at 3:00 PM EST to Marilia_Mateo@nps.gov.

This procurement is designated as a 100% small business set-aside under NAICS code 212319 (Other Crushed and Broken Stone Mining and Quarrying) with a size standard of 550 employees. The contract is structured as a firm-fixed-price arrangement with a performance period extending 30 days after award, specifically from September 22, 2025 to November 21, 2025. All deliveries must occur within 30 calendar days of the Notice to Proceed during normal operating hours (0700 to 1630 EST, Monday through Friday). The materials will support rehabilitation of approximately 3 miles of trail, addressing hazards such as mudholes, erosion, and failing drainage structures. Performance will take place at Big South Fork National River and Recreation Area in Tennessee, with applicable wage determinations covering both Tennessee (Scott County) and Kentucky (McCreary County) jurisdictions.
