About this opportunity
The Indian Health Service seeks construction of a 19-unit apartment building at Indian Route 6290, Tonalea, Arizona, with proposals due November 12, 2026. The procurement is an Indian Small Business Economic Enterprise (ISBEE) set-aside, restricting competition to firms meeting ISBEE eligibility requirements under the Buy Indian Act.
Place of performance is Tonalea, Arizona (Coconino County) on Navajo Nation lands. The project adapts an existing 19-unit design to the new location, comprising eight one-bedroom units, eight efficiency/studio units, two two-bedroom units, and one ADA-accessible one-bedroom unit totaling approximately 19,500 square feet. The building incorporates post-tensioned slab-on-grade foundations, wood-frame construction, high-efficiency split heat pump HVAC systems (minimum 19.5 SEER2), electric water heaters, a 42.745 kW solar photovoltaic parking canopy, and full sprinkler protection. All work must comply with the 2021 International Building Code, 2017 National Electrical Code, and Navajo Nation environmental and utility regulations. Contractors bear responsibility for obtaining federal, state, and tribal permits and licenses, including Navajo Nation Division of Economic Development and Tribal Employment Rights Office (TERO) licensing. The geotechnical report indicates silty sand soils with collapse and expansive potential; allowable bearing pressures range from 2,500 to 3,000 psf depending on depth.
The contract is firm-fixed-price with a 365-calendar-day performance period and an estimated construction magnitude between $5 million and $10 million. Work commences within 10 days of notice to proceed. Contractors must perform at least 15 percent of contract cost with their own employees under SBA limitations on subcontracting for ISBEE firms. Bid bonds equal 20 percent of bid price or $3 million, whichever is less, and performance and payment bonds are required within 10 days of award. The NAICS code is 236220, Commercial and Institutional Building Construction, with a $45 million size standard. PSC is Y1FA, Construction of Family Housing Facilities.
Source selection uses Lowest Price Technically Acceptable (LPTA) evaluation, awarding to the lowest-priced technically acceptable proposal demonstrating satisfactory past performance. Technical proposals must address relevant experience adapting designs to new locations and constructing multi-unit apartment buildings, with narrative addressing schedule, logistics including remote site and utility coordination with Navajo Tribal Utility Authority (NTUA), and past performance via CPARS or optional Past Performance Questionnaires for projects completed within six years. Davis-Bacon prevailing wage determination AZ20260043 (effective May 18, 2026) applies; all workers are subject to paid sick leave requirements and the federal minimum wage of $13.65 per hour through December 31, 2026. The site visit occurred August 3, 2026, with a preproposal conference held concurrently. Amendments A01 through A04 extended the proposal deadline progressively from September 24 to October 8 to October 22 to the current November 12, 2026 deadline, and posted Q&As, site visit sign-in sheets, geotechnical reports (final report dated September 10, 2024), and updated HHSAR clause 352.223-70 (Safety and Health, October 2026 version) addressing OSHA, occupational health, and hazardous materials compliance. Offerors must acknowledge all amendments prior to the deadline.
