The OHSU ED project was a (2) phase renovation of an active Emergency Department. During the first phase, OHSU entrusted us with the renovation of (4) Level One primary Trauma Rooms and (10) Acute Care Exam Rooms while keeping the Emergency Department fully functional and operating. We compacted our work schedule so that no more than (1) Trauma Room was down at a time and built hard partitions to minimize our impact to their operations. The second phase brought the reconstruction of the corridors, (10) Observation Rooms, Radiology, (2) Nurse Stations and all staff support areas while the ED remained operational.
