Casa Grande approved Resolution 5892 to award a construction-manager-at-risk contract with a guaranteed maximum price of $12,375,553 to Ellison Mills Contracting LLC for McCartney Road Segment 1 (Pinal Avenue to east of Treckle Road), with council asking staff for a cost-progression ('waterfall') chart.
The Casa Grande City Council on March 2 approved Resolution No. 5892, authorizing a guaranteed-maximum-price contract with Ellison Mills Contracting LLC for construction-manager-at-risk services on McCartney Road Segment 1, from Pinal Avenue to just east of Treckle Road.
City staff member Kevin summarized the procurement process and recommended Ellison Mills as the most qualified firm after a request-for-qualifications, site visit and a committee review. Kevin said the project includes widening the roadway to four lanes with turn lanes, medians for access control, new asphalt pavement, curb and gutter, and sidewalks. He presented a GMP "not to exceed $12,375,553." Kevin told council that, if approved, work could mobilize around March 15 and noted the contract for pre-construction services was completed in November 2025.
Council members asked for a waterfall-style chart showing how the price progressed from 30% design to the GMP and any value-engineering steps. Kevin agreed to provide the requested breakdown.
The council approved the resolution by roll call; the motion passed unanimously.
Resolution: Resolution No. 5892, awarding Ellison Mills Contracting LLC construction-manager-at-risk services for McCartney Road Improvement Project Segment 1.
