Tonto Hills Water Line Improvements

Maricopa County is soliciting sealed bids for the Tonto Hills Water Line Improvements project, a comprehensive infrastructure initiative involving the installation of new water lines throughout the Tonto Hills community. The project requires removing existing water lines constructed from Asbestos Cement Pipe (ACP), Ductile Iron Pipe (DIP), and PVC, and includes associated road surface restoration through chip sealing. Contractors must complete all construction work within 180 calendar days of the Notice to Proceed, with an additional 120 calendar days allocated for administrative processes, resulting in a total contract performance period of 300 calendar days. Bidders must be registered with BidNet Direct and submit pricing through the e-procurement platform, with a mandatory 10% bid security requirement. The project is located within Maricopa County, Arizona, specifically in Township 1N and Range 5E, Sections 10 and 15, and requires compliance with extensive environmental regulations, including protections for native wildlife and proper handling of potentially hazardous materials. A non-mandatory pre-bid teleconference is scheduled, and sealed bids are due on June 3, 2025, at 2:00 p.m. Mountain Standard Time.

Contractors must hold a current Arizona contractor's license and provide comprehensive insurance coverage, including $2,000,000 in commercial general liability, $2,000,000 in automotive liability, and $1,000,000 in workers' compensation. While no specific set-aside designations for disadvantaged enterprises are explicitly mentioned, the project demonstrates commitment to non-discrimination provisions and compliance with Title VI of the Civil Rights Act. The project will be funded through Maricopa County's Department of Transportation and requires adherence to federal and state regulatory standards. An allowance of $20,000 has been established for potential driveway paver reinstallation or replacement. Contractors will need to coordinate with the Tonto Hills Domestic Water Improvement District and obtain Approvals to Construct from the Arizona Department of Environmental Quality. Environmental mitigation measures are critical, including protocols for handling protected species like Gila monsters and Sonoran desert tortoises, conducting bird nest surveys, and managing potential asbestos-containing materials in compliance with National Emission Standards for Hazardous Air Pollutants.
