Scope

Replace the air-handling units and associated electric duct heaters for the entire building in four phases. Due to limited access, the building exterior wall was opened on two opposite sides from top to bottom to provide a path for new air units. The design also included new humidification systems, new building direct digital control system, and new roof-mounted energy recovery units with new outside air distribution system also included.
