Originally built in the 1950s, the four-story Cutler Hospital was renovated and upgraded to comply with the operational needs and security requirements of the Federal Medical Center. Existing medical-surgical beds were renovated to 132 beds, including 12 for intensive care and 21 for high-security patients. The existing ICU unit, pharmacy, dental area, and emergency room were removed and replaced with new facilities. Operating rooms, x-ray rooms, medical storage area, nurses' station and conference rooms were renovated and updated. A kidney dialysis unit and MRI unit were added to the facility. Additional facilities include a new psychiatric hospital unit for 150 inmates, two high-security "closed units," three medium security "open units," a 72-cell special housing facility, a 128-cell medium security facility, and two 128-cell low security housing blocks.  Other facilities include food preparation and dining, common areas for maintenance shops, storage, laundry, chapel and recreational areas.
