The selection was made using an Invitation for Bids process set forth in Section 34-201 of the Arizona Revised Statutes. Two bids were received on September 23, 2025 and were sent to the Equal Opportunity Department for review to determine subcontractor eligibility and contractor responsiveness in demonstrating responsiveness to Small Business Enterprise program requirements.
The Opinion of Probable Cost and the two lowest responsive, responsible bidders are listed below:
Opinion of Probable Cost: $13,471,315
Stacy and Witbeck, Inc.: $12,064,480
Hunter Contracting Co.: $13,503,330
Due to volatile material costs and increased labor prices in the construction industry, a 10 percent contingency is being requested to allow for project uncertainties. The initial contract will be executed at the bid amount of $12,064,480. Use of the 10 percent contingency above the bid amount will not be allowed without the prior written approval of the Water Services Department and the City Engineer.
The bid award including the added contingency is within the total budget for this project.

Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement.
