This Contract provides for the installation of approximately 1,800 feet of 12-inch DI water main from the City’s water system at the east end of the City’s Sportsman Park, along the north side of SR 410 to a point of connection at the City’s Boise Spring Chlorination Station. Approximately 500 feet of asbestos cement main and 400 feet of cast iron main must be removed to accommodate the new main. In addition, the project includes about 185 feet of 2-inch water main replacement along with valves, a temporary chlorine dosing system, and other appurtenances. This project will require that all lane closures shall be limited to Sunday-Thursday, 8:00 p.m. through 5:00 a.m. In addition, work involving removing any of the existing main cannot begin until the City completes a planned shutdown of the transmission main on September 8, 2025, at which time contract time will start. Other work may be completed prior to the shutdown in accordance with Special Provision 1-08.4.
