Mountain States Regional Office Critical Systems Upgrade

Colorado Springs, CO

This four-story, 400,000-square-foot building houses a 24×7 call center, administrative spaces, fitness center, full-service kitchen, and dining hall, as well as customer financial services. Originally constructed in two phases, phase 1 (A-Core) was served by redundant 300-ton chillers, while Phase 2 (B-Core and C-core) was served by redundant 500 ton chillers.

This project provided Tier III resiliency to the critical systems (power and cooling) for the central computer room and 12 distributed communication rooms. To make room for the new critical cooling plant, the existing A-Core chiller plant was phased out and integrated into the ex C-Core chiller plant, which now includes three 500-ton machines. The central chiller plant only operates during occupied hours and only during the cooling season. In order to maintain a reliable source of 24×7 cooling year round, a new critical cooling plant was provided, consisting of a new 100 ton modular air-cooled chiller, complete with redundant compressors and integral free-cooling modules. Fully redundant CHW pathways have been incorporated throughout the building.

A new 600 kW diesel generator and redundant (system + system) 200 kW UPS Rooms provide reliable power to the critical information technology areas, as well as the dedicated mechanical systems.
