Description

The U.S. Department of the Interior is seeking a qualified contractor to replace the Mammoth Water Line within the Yellowstone area. The project involves the removal of existing water infrastructure, installation of new water mains, connection to existing distribution networks, and compliance with environmental and safety regulations. The effort will likely require coordination with park authorities, adherence to federal construction standards, and may involve remote site logistics. • Scope: Full replacement of the Mammoth water line (pipeline removal, new pipe installation, testing, and commissioning). • Required expertise: Heavy civil construction, water‑utility infrastructure, environmental compliance, and experience working in federally‑managed lands. • Deliverables: Constructed water line meeting design specifications, as‑built documentation, and post‑construction performance testing. • Potential constraints: Weather, wildlife protection, limited access roads, and strict permitting requirements. • Evaluation criteria likely include technical capability, past performance on similar federal water‑line projects, cost proposal, and schedule feasibility.

Budget estimate

$2,000,000 – $10,000,000

Based on typical costs for replacing a municipal‑scale water line in a remote, federally‑managed area, the contract is likely to be in the multi‑million‑dollar range. Factors influencing the amount include length of pipe, terrain difficulty, environmental mitigation, material costs, and the need for specialized equipment. A rough estimate would place the award between $2 million and $10 million, with the lower end representing a short segment with minimal complications and the higher end reflecting a longer, more complex stretch requiring extensive environmental safeguards.
