Irrigation canal lining maintenance

The Department of the Interior's Bureau of Indian Affairs Western Region is seeking a small business contractor to perform irrigation canal lining maintenance for the Colorado River Irrigation Project (CRIP). The contract involves repairing and replacing broken or missing concrete segments across approximately 140 miles of canal infrastructure, with specific requirements for earthwork preparation, wire grid reinforcement, and gunite material application. Contractors must possess an Arizona Contractor's License and be prepared to perform maintenance during scheduled dry-up periods in December, January, and February, with an ability to respond to emergencies within 48 hours. Interested vendors must submit their Arizona Contractor's License number via email to Randall.Brown@bia.gov or by phone at (520) 560-2590 before the response deadline of January 27, 2025. The solicitation falls under NAICS code 238110 with a $19 million annual size standard, targeting poured concrete foundation and structure contractors.

The opportunity is a 100% small business set-aside with a contract period of 12 months, focusing on 19 planned dry-up days for maintenance work. Contractors will be required to submit pricing as a per-day rate for 10-hour workdays, with the CRIP providing gunite material and wire grid while the contractor handles transportation and installation. The project involves working on canal lining with side slopes ranging from 6-25 feet in height, requiring precise 4-inch thick gunite application using 4"x4" wire grid reinforcement. Payment will be processed weekly through the Invoice Processing Platform (IPP) system, and daily coordination meetings with CRIP staff are mandatory. While no incumbent contractor is mentioned, the detailed Statement of Work suggests a complex maintenance operation with specific technical and safety requirements that will likely influence contractor selection.
