GBA provided commissioning services for a 27,000-square-foot emergency department addition; 43,500 square feet of shell space; 17,000 square feet of basement mechanical/electrical space; and 6,000 square feet of renovated area in the existing hospital.



Condell’s emergency department expansion program, totaling 87,500 square feet of new facilities plus 6,000 square feet of renovations, added 25 new exam rooms, three trauma rooms, a satellite lab, and radiology space.

  • Design-phase commissioning included review of construction documents and production of commissioning specifications.
  • Functional performance testing included the air-handling systems, air-cooled chillers with chilled water pumps, heating hot water boiler plant, domestic hot water system, and emergency generators.
  • Functional performance tests of air-handling units identified non-calibrated airflow measuring stations and incorrect supply-to-return fan tracking, leading to inadequate building pressurization. Corrections resulted in an appropriately pressurized building.
  • Excessive cycling of high-efficiency heating hot water boilers and lack of heating hot water temperature reset were identified and rectified.
  • The location of the domestic water flue into an air intake was identified as a problem. Water heaters failed to operate properly when the air handling unit was in economizer mode. Relocation of the flue resulted in reliable domestic hot water heater operations.
