About this file
The document includes construction drawings and specifications for replacing two cooling towers at Building 1002 on Keesler Air Force Base. The project involves demolishing the existing cooling towers and associated piping and controls, installing a temporary chiller, and constructing two new cooling towers with structural framing, mechanical, electrical, and control systems. Key aspects of the work include removing and disposing of existing materials; installing new chilled water piping, cooling tower cells, basins, and structural framing; connecting make-up water, drains, and electrical and control components; and restoring affected areas to original conditions. A site visit is scheduled for 29 July 2020 at 9:00 AM for contractors to access the base and facility. Safety protocols for COVID-19 such as face coverings and maintaining social distance are required for all attendees.
