Heffron was contracted to modernize the air handling infrastructure within Operating Pod 1G at Washington Hospital Center — replacing 26 supply air VAV units with new fan arrays, coils, controls, dampers, AQUIS treatment systems, and filter racks, followed by installation of a Glyco Air Coiled Subcooling Chiller.

The work advanced while the hospital remained fully operational and while scheduling pressures intensified under elevated COVID-era constraints. Coordination with MedStar facilities management was constant, because every sequence had to protect active clinical operations first.
