B. PROJECT TITLE: Repair HVAC – Arnold & Harmon Hall

C. PROJECT LOCATION: 2302 Arnold & 2304 Harmon Hall, USAF Academy, Colorado

2. DESCRIPTION OF PROJECT:

A. PROJECT BACKGROUND: Chilled water that is generated at Harmon Hall is supplied to Harmon Hall, Arnold Hall and Polaris Hall. Cooling towers are located on Arnold Hall roof which is piped vertically and through tunnels to Harmon Hall. Harmon Hall HVAC system consists of water cooled heat pumps which reject heat to the chilled water system via heat exchangers located in the basement of Harmon Hall. This project will replace the cooling towers located on the roof of Arnold Hall. The cooling heat exchangers at Harmon Hall will be upgraded to flat-plate type and various piping and controls will be upgraded. A temporary air cooled chiller will be utilized during cooling tower demo and replacement. Hazardous material testing was performed and results are included with project documents.

B. CONSTRUCTION SCOPE: The Contractor shall execute the project as shown in this SOW, Project Drawings, and Specifications. In case of conflicts between documents, the order of precedents will be Contract, SOW, Specifications and then Project Drawings.
