This is an Offer and Acceptance form issued by the City of Tucson for a Construction Manager at Risk (CMAR) contract related to the Advanced Water Purification Demonstration Facility project. The City of Tucson seeks construction services to develop a 2.5 million gallon per day Advanced Water Purification Demonstration Facility located at 2550 W. Sweetwater Drive that will purify tertiary effluent to potable water standards in compliance with Arizona Department of Environmental Quality requirements. The project scope includes building upgrades, AWP equipment installation, piping modifications, and site improvements such as landscaping, paving, and parking lot construction. Interested firms were required to submit Statements of Qualifications by October 23, 2025, at 2:00 pm local time, with a pre-submittal meeting conducted on September 30, 2025, via Microsoft Teams and an on-site visit scheduled for October 2, 2025, at 1:00 pm. Construction is expected to be completed by January 2027, with the facility fully operational by September 2027.

The estimated total construction cost is $10,000,000, with the conceptual design suggesting a project cost of approximately $5.3 million and a contingency range between $1.6 million and $8 million. The project is funded through a United States Bureau of Reclamation grant. The procurement includes Small Business Enterprise program provisions applicable to contracts with estimated construction values of $100,000 or more, requiring participation from firms certified by the City of Tucson under Chapter 28, Article XIII of the Tucson Procurement Code. Potential cost savings of approximately $350,000 may be achieved if Tucson Water purchases major equipment directly. The recommended treatment approach utilizes a reverse osmosis-based treatment train featuring microfiltration/ultrafiltration, reverse osmosis, ultraviolet advanced oxidation process, and optional granular activated carbon treatment.
