As part of the renovation, the team performed structural upgrades to the building's roof to support six new make-up air units. They removed half of the building's slab and depressed it two feet to accommodate the cleanroom access flooring. The team also installed 112 High-Efficiency Particulate Air (HEPA) plenums and 60 recirculation units. Alongside the building, DPR built a back service pad for the central utility plan, which includes chilled water, condenser water, a boiler and an emergency generator.
Despite the highly complex nature of the project, DPR delivered Phase 1 a day ahead of schedule with zero defects, and the project was turned over to the owner with no outstanding change orders.
