Superintendent Thomas Brown’s primary challenge was manpower, but various shutdowns due to a hurricane, eclipse, and snowstorm presented obstacles to the team as well. The new HVAC system includes (2) 900 GPM cooling towers, (9) vertical self-contained units, (2) 40HP primary pumps, (3) 30HP secondary pumps, and associated ductwork and piping. The project duration is over 400 days, but the end is in sight with completion scheduled for June 13, 2018.
