Fairfax Chiller and Roof Replacement
Owner: A National Telecommunication Company
Delivery Method: Design-Bid-Build
14,750 square feet
The Chiller and Roof Replacement project, completed on schedule in March of 2018, involved the removal and replacement of two existing end of life 140-ton air cooled chillers from the roof while also replacing the entire 14,750 sf modified bitumen roof system. The sequencing for the replacement of the chillers required one chiller to be removed, replaced and validated before proceeding to the next chiller to maintain acceptable temperatures to the equipment rooms of the active mission critical facility. Additional coordination was required to allow the chiller replacement to happen concurrently with the roof replacement to minimize overall project schedule and general conditions costs. Additional complexities were encountered when the existing conditions did not match the as-built drawings so modified structural design and modifications were required for chiller roof mounted supports.
