MEMORANDUM Page 5 November 25, 1983 item =26: Glass dcors are either 1/2" tempered or 1/4" tempered glass and glazing subject to impact adjacent to doors is 1/4" tempered glass at standard doors and 1/2" tempered or greater at security doors. Comments on Exits Item #1: The stairways are all pressurized mechanically in the event of fire to keep smoke out. Each stair has an individual intake fan and exhaust vent. Stair #2 at grids A-8 is designed as a smoke proof enclosure in reality. Stair 42 extends to the roof; see plan and section on sheet A8.1. The roof door will be changed to meet the 11-hour rating required. (Change order required.) The "penthouse" is concrete construction and meets the 1-hour rated requirement. lele feel the stairway design meets the intent if not exceeding the requirements for a smoke proof encicsure. Preliminary meetings with the Everett Building Department indicated the stairways were acceptable as designed. Item 42: Disagree. Exiting as designed meets both the intent of the code and stringent security requirements necessary in a detention facility. It is impossible and undesirable to provide two means of egress from each cell. Each housing module has two exits, both on the main level and the mezzanine level, controlled by security staff. The outdoor recreation area is designed as an exterior exit balcony and serves as a place of refuge before inmates are taken down the stairs. We do not interpret the outdoor recreation space as an inter- vening room. The secondary exit from the mezzanine must pass through 2 visiting rooms. While this doesn't comply with the code requirements, this should be acceptable because security staff are required to operate these doors and evacuation would occur in an orderly, secure way. Each housing module dayroom exits directly into an outdoor recreation space and a secure lobby, both of which have direct access to an exit stair. The intended staffing concept has one staff officer in each module 16 hours a day. flight operation has one staff officer on each floor as a rover between flours, and one officer at each floor secure lobby. Item a3: Outdoor recreation areas should not be considered an adjoining room, as they function as exterior exit balconies. Item #4: Agree. Wall construction complies. Doors in this lobby will be 20 min. rated as required. (Change order required.)
