This solicitation, numbered 1232SA26Q0880, is a combined synopsis and request for quotation for the installation of a new 12.47 kV solar array on the rooftop of an existing building at the Southwest Watershed Research Center in Tucson, Arizona, with associated patch and repair work to the roof membrane. The procurement is structured as a Total Small Business Set-Aside under NAICS code 237130, with a small business size standard of $45 million, and is open only to responsible small business concerns.

The Contractor must also maintain an on-site superintendent with five years of relevant experience and familiarity with EM 385-1-1 safety protocols, appoint a formally designated Site Safety and Health Officer, and submit a Site-Specific Safety Plan within ten days of award.
