The Indian Health Service is soliciting proposals for the Zuni Quarters Sewer Improvement Project, a construction project involving the installation of two gravity sanitary sewer lines (Lines A and B) with associated infrastructure improvements at the Zuni Comprehensive Community Health Center in Zuni, New Mexico. The scope includes constructing new 8-inch PVC sewer mains, installing 4-foot diameter precast concrete manholes, reconnecting 4-inch PVC service lines, and performing ancillary work such as curb and gutter replacement, driveway restoration, and landscape work. Key contract requirements include a mandatory 90-calendar-day period of performance from the Notice to Proceed, submission of a performance bond within 10 days of award, compliance with prevailing wage determinations established by the Department of Labor, adherence to the Buy American Act, and coordination with tribal employment requirements (TERO costs). The evaluation will employ a Lowest Price Technically Acceptable (LPTA) source selection methodology, with contractors required to submit two volumes comprising a technical proposal demonstrating specialized construction experience through detailed project documentation and past performance references, along with a price proposal utilizing the revised price schedule. The deadline for contractor questions is January 21, 2026 (14 days prior to the final proposal due date), and proposals are due on February 4, 2026, at 2:00 PM Central Standard Time, following three amendments that clarified project requirements, corrected pricing schedules, and addressed 49 pre-proposal inquiries.

This solicitation is a 100% Small Business set-aside under NAICS code 237110 (Water and Sewer Line and Related Structures Construction) with a $45 million size standard, with no incumbent contractor identified in the available documentation. The estimated contract value ranges between $100,000 and $250,000, representing the complete scope for both sewer lines with all associated materials, labor, testing, and restoration work. The project encompasses approximately 583 linear feet of new 8-inch sewer main installation across two separate lines, installation of multiple 4-foot diameter manholes with hydrogen sulfide protection via Moxie 1800 Super-Admix additive, and reconnection of approximately 270 linear feet of 4-inch PVC service lines to existing structures. Performance bond requirements and an all-inclusive one-year warranty on labor and materials are mandatory upon contract award. The work will be performed at the Zuni Quarters location in Zuni, New Mexico, within McKinley County, with the contractor responsible for maintaining sewer line operability during construction, developing traffic control plans in coordination with IHS, and managing coordination with New Mexico One-Call for utility mark-ups and locates.
