Purdue Pharma Manufacturing’s two-story oral solid dosage manufacturing plant includes a 128,000-sq-ft first floor and a 60,000-sq-ft second floor. Production areas feature clean room spaces with epoxy flooring and epoxy-painted walls and ceilings. Approximately 46,000 sq ft accommodates administrative offices, laboratories and associated support areas. To overcome impacts from above-average precipitation during the project’s first year of construction, in 2014, contractors covered the entire building pad with a 66-in. stone base, which allowed crews to complete the building foundations early and maintain overall schedule.
