Summary

This document is a shop drawing for precast concrete box culverts submitted by Rinker's in connection with the City of Kingman's Flying Fortress Parkway Phase II construction project (IFB 2026-IFB-003). The shop drawing provides detailed specifications and design documentation for the precast box culvert components that form part of the project's drainage infrastructure improvements. Pre-cast box culvert deliveries are scheduled between March 2026 and June 2026, with the overall construction project requiring completion within a mandatory 150-calendar-day period (accounting for 15 rain days). The non-mandatory pre-bid meeting is scheduled for March 12, 2026, at 10:00 a.m. Arizona time with a Zoom option available. Written questions must be submitted through the OpenGov procurement portal by 10:00 a.m. Arizona time on Monday, March 16, 2026, and sealed bids are due electronically by 10:00 a.m. Arizona time on Tuesday, March 24, 2026, through the City of Kingman's procurement portal.

The project evaluation prioritizes overall cost inclusive of taxes and the contractor's demonstrated ability to meet the 150-day construction schedule. Contractors must perform at least 51 percent of the work with their own forces unless written approval for greater subcontracting is obtained from the City. Bidders are responsible for factoring Transaction Privilege Tax (TPT) into their overall pricing. The contract will be awarded to the lowest responsible, responsive bidder meeting all prescribed requirements and qualifications. The solicitation documents do not specify an overall project budget range or award value. Contractors must hold an Arizona Registrar of Contractors (ROC) license for public roadway work, secure a City of Kingman business license where applicable, provide a statutory bid bond, and submit notarized contract agreements. Failure to complete work within the 150-day contract period will result in liquidated damages as specified in the Maricopa Association of Governments Section 108 standards. The successful contractor will not commence billable work until receiving a purchase order from the City of Kingman.
