COW island culvert

The Bureau of Land Management is seeking a contractor to replace a damaged 48-inch diameter corrugated metal pipe culvert on Cow Island Trail at the Upper Missouri River Breaks National Monument in Blaine County, Montana. The project involves removing the existing fully plugged culvert and installing a new 48-inch by 120-foot annular riveted, poly-coated corrugated metal pipe culvert, along with excavation, bedding preparation, backfilling, and site restoration work. Contractors must complete various documentation including a cover letter, signed Standard Form 18, and bid schedule, while complying with Buy American requirements and prevailing wage determinations under the Davis-Bacon Act. The evaluation will be based on the lowest total price from a responsible quoter who meets all solicitation requirements, terms, conditions, and technical specifications. A mandatory site visit was scheduled for June 18, 2025, questions were due by June 23, 2025, and proposals are due by July 14, 2025 at 2 PM Denver time.

This opportunity is designated as a total small business set-aside under NAICS code 237310 (Highway, Street, and Bridge Construction) with a $45 million size standard. The project scope includes an estimated 300 cubic yards of excavation, 15 cubic yards of 3-inch minus pit run material, and 25 cubic yards of select culvert bedding, with work to be priced on a lump sum basis across four bid items: mobilization, excavation and backfilling, the culvert itself, and road base materials. The contractor must complete all work within 30 calendar days from the official start date, with final completion required no later than September 1, 2025. Performance will occur approximately 20 miles west of Hays, Montana, at coordinates 47.95444 N and 109.05167 W, spanning both BLM and private land.
