Brooke Army Medical Center Central Plant Renovations

Brooke Army Medical Center
Fort Sam Houston, TX

The existing 4,800-ton water-cooled central plant was expanded and renovated to increase chilled water firm capacity to 6,000 tons with 1,500 tons of reserve capacity. Each of the five (5) existing 1,200-ton chillers were replaced with new 1,500 ton machines and the chilled temperature difference of the plant was increased from 10°F to 12°F (to utilize existing pipe infrastructure to save first costs). Primary and secondary pumps were replaced to compliment the new chillers. The entire plant was modeled in 3-D to accurately coordinate the required work and ensure minimal outages, as the facility must remain operational during construction. The three (3) existing steam boilers were also replaced with new 600 hp units. In addition, the DDC controls system was completely replaced. In order to accelerate the schedule, the chillers and boilers were selected and bid prior to the completion of the design. As the production schedule for the chillers was expected to exceed 16 weeks, the effort saved valuable time in the phased change-out effort
