Contract Types & Construction Contracts

Contract Types

Contract Types

The City of Tucson normally contracts for two types of purchases, either a one time contract or a term contract. One Time Contract: The City procures required services or materials on a one time basis.

A firm price is requested for fixed quantities with single or multiple delivery sites. Depending on the dollar amount of the purchase, the formal sealed solicitation method or informal quotation method is used.

Term Contract: The City has established, and continues to establish, term contracts for estimated quantities of materials or services commonly used in volume by specific departments or on a City-wide basis.

These contracts are awarded by a formal sealed solicitation method for a specified period of time.


Construction Contracts

Construction contracts for City projects are generally competitively bid through the Invitation for Bid (IFB) process and are awarded to the lowest responsive and responsible bidder.

Based upon Alternative Delivery Method legislation, applicable City projects may now be competitively solicited through the Request for Qualification (RFQ) process and awarded to the most qualified offeror.
