Appendix_D_-_La_Paloma_Reservoir&Booster_72_x_72-inch_Freestanding.pdf

This is a technical specification document for the La Paloma Reservoir & Booster 72x72-inch freestanding control panel prepared by the City of Tucson Water Department located at 4742 North Oracle Road, Suite 310, Tucson, Arizona 85705. The document contains 24 sheets of detailed engineering drawings and specifications (project number 9-165-2019) that were reviewed and approved by Michael P. Abbott on April 13, 2021. The specifications define the technical requirements and design standards for the fabrication of a freestanding 72x72-inch control panel used for the La Paloma Reservoir and Booster system. This panel is one of four specific panel types identified in the City's annual requirements contract for station control panel fabrication (RFP No. 240048), with an estimated procurement of approximately 20 panels annually across all types. The solicitation requires in-state Arizona fabrication by UL508A-rated contractors and includes a contract term of one year with potential extensions for up to four additional one-year periods.

The estimated annual expenditure for the entire station control panel program is approximately $980,000. Contractors must be Arizona-based to facilitate contract administration, testing capabilities, and minimize shipping costs and travel time. All panels must be completely assembled, wired, and tested to UL 508 rating standards, with comprehensive documentation including calibration certificates and as-built drawings provided upon delivery. The procurement includes Section 3 Program requirements mandating that 25% of labor hours be performed by Section 3 Workers and 5% by Targeted Section 3 Workers. Contractors are required to provide Allen-Bradley spare parts including CompactLogix controllers, I/O modules, interface cards, display units, and network switches (two of each). The City anticipates awarding contracts to multiple contractors to ensure adequate product line selection and geographic coverage, with specific panel jobs awarded based on the contractor's most advantageous quote regarding price and delivery time.
