In order to ensure competition, the successful bidder may not submit a bid or enter into a contract with the public agency that differs from the bidding specifications. “A bid containing terms that materially deviate from the terms in the bidding specifications or as required by law can never be the basis for an agreement. The legal notice soliciting bids is really a request for offers. The offers or the bids must conform to the specifications in the notice.” Arizona Bd. of Regents for and on Behalf of University of Arizona v. Main Street Mesa Associates 181 Ariz. 422, 426, 891 P.2d 889, 893 (Ariz.App. Div. 1,1994) (citing Article 10, § 8 of the Arizona Constitution s, which provides that “Every sale, lease, conveyance, or contract of or concerning any of the lands granted or confirmed, or the use thereof or the natural products thereof made to this State by the said Enabling Act, not made in substantial conformity with the provisions thereof, shall be null and void”).
