The National Park Service Intermountain Region is seeking a small business contractor to replace concrete sidewalks and aprons at three residential houses (Houses 6, 5, and 4) within Navajo National Monument. The project involves demolishing approximately 202 square feet of existing concrete, removing base course, recompacting subbase, and installing new 4000 PSI concrete with a "cedar" color specification. Sidewalks will be approximately 98 square feet each with 4" depth, and driveway aprons will be 104 square feet each with 6" depth. The solicitation (No. 140P1525R0007) requires contractors to complete the work before the end of Fiscal Year 2025, minimizing impact on park operations. Proposal responses are due by May 8, 2025, at 5:00 PM EDT, with a mandatory site visit conducted on April 7, 2025, and a series of amendments extending response dates and providing additional clarification.

The contract is a 100% small business set-aside with a NAICS code of 238110 and a small business size standard of $19M. The project is located within Navajo Nation boundaries, requiring contractors to verify applicable tribal regulations and ensure compliance with environmental standards. Contractors will not be provided park resources, including water, and must remove demolished concrete daily. All work must be coordinated with the Navajo National Monument Facility Manager, with specific technical requirements including a 4,000 PSI concrete mix with a 4" slump. The solicitation is administered by NPS, IMR - Arizona MABO, located in Flagstaff, Arizona, with contact personnel including Jessica Owens and Ryan Young. While no specific award value is mentioned, the project involves precise concrete replacement work at a national monument site.
