Summary
An April 2013 assessment identified the need to rehabilitate Reservoir 1-ES1-3, a 20-million gallon reservoir dam located at the 64th Street Reservoir Facility. Rehabilitation will include, but is not limited to: new standing seam aluminum roof deck replacement, column and roof framing repair, new membrane liner, replacement of roof drainage channel curbs, and installation of a mixer system within the reservoir.

A Small Business Enterprise (SBE) goal of one percent was established for this project.

One bid was received according to section 34-201 of the Arizona Revised Statutes by the Street Transportation Department on March 27, 2018.

The one bidder was deemed responsive. The Engineer's estimate and the lowest responsive, responsible bidder is listed below:
