GRCA 257282 - Replace Wastewater Plant at South Ri

The National Park Service Denver Service Center Contracting Services Division is soliciting proposals for replacement of the South Rim Wastewater Treatment Plant at Grand Canyon National Park (GRCA 257282), with proposals due November 18, 2026. The "No Set-Aside Used" designation applies, and the negotiated RFP (140P2026R0101) is open to unrestricted, full and open competition. It is not sole-source and carries no contract vehicle requirement. The requirement is unfunded, with award contingent on funds becoming available, though the source states a high expectation that they will.

Work is performed in Grand Canyon Village, Arizona 86023. Scope includes a new 0.65 million gallon per day membrane bioreactor plant producing Class A+ reclaimed water and Class B biosolids, demolition of existing facilities in Phase 2, a compost facility, access road improvements, and 12 months of operations and maintenance support following startup. The period of performance runs February 1, 2027 through February 1, 2030, with completion within 1,095 calendar days. Pricing is firm-fixed-price across four base line items (plant replacement, compost facility, O&M support, and access road improvements) and two options (radon gas testing and active radon mitigation system). Liquidated damages are $5,856.43 per calendar day. The SF 1442 places the magnitude above $10 million, while the pre-bid presentation states contract value exceeding $100 million. Performance and payment bonds are required, with performance bonds due within 15 calendar days of award.

Key personnel include a project manager, job site superintendent, quality control manager, and safety manager, with substitutions restricted during the first 30 days and requiring Contracting Officer approval. Key trade assignments for process services, mechanical/plumbing, electrical, and civil work must be identified and remain permanent unless approved otherwise.

Evaluation covers seven factors: technical approach, key personnel experience, project experience (up to four projects completed within the last seven years), management approach and project team, schedule, small business participation, and past performance. The source does not assign factor weights. The solicitation sets small business subcontracting goals of 30% overall, with 5% each for small disadvantaged, service-disabled veteran-owned, and women-owned small businesses, and 3% for HUBZone firms.

Amendment 0006 extended the proposal due date from November 2, 2026 to November 18, 2026. Amendment 07, issued October 22, 2026, contains 296 questions and answers, with many technical responses deferred to upcoming amendments. The NAICS code is 221320 and the PSC is Y1ND.
