Pharmaceutical Distribution Center

IMEG provided structural, mechanical, and plumbing design, along with industrial architectural services, for the renovation of a 60,000-sf building in Decatur, Alabama, into a pharmaceutical distribution center, re-arranging the existing layout to a new layout.

A new air-handler was provided for the new clean rooms to allow continued use of the existing clean rooms during construction. The HVAC system for the clean rooms was designed for ISO8 with 25 air changes per hour (ACH) in the repackaging and sampling rooms and 12 ACH in the vestibules. All repackaging rooms have exhaust to control powder dispersal; however, the liquid room, potent powder room, and sampling room has 100% exhaust. The vestibule was pressurized +0.05 inches water gage above the adjacent warehouse and repackaging room to prevent flow from the repackaging room to the warehouse.

A new 1 MW diesel generator was provided to accommodate the additional HVAC loads. A new main switchboard, transfer switch, motor control center (MCC) and two distribution panels (480/277V) were set in the electrical room. The MCC will serve all of the new HVAC loads and the distribution panels shall serve the three lighting and receptacle panels
(208/120V).
