5(90y-027 01 SALUS ;0 HEALTHCARE ARCHITECTURE March 28, 2019 Drew Martin, Associate Engineer City of Everett Development and Construction Public Works - Permit Services 3200 Cedar Street, 2nd Floor Everett, WA 98201 Subject: Kaiser Permanente Everett Medical Clinic 2930 Maple Street Everett, WA Request for approval of new cross -corridor door Dear Drew, I met with you February 27th to discuss adding a cross -corridor door in a second -floor corridor of the KP Everett Clinic. Currently there is an L-shaped corridor that serves a series of offices and has existing Doors-A&B at either end (see drawing SD2.02). Kaiser Permanente wants to separate this office area into two parts: a behavioral health office area and an administration office area. This separation will create a 72- foot corridor and a 47-foot corridor with new locked Cross -Corridor Door-C in-between (see drawing SD2.01). This will make both corridors into dead ends. Per the IBC Section 1020.4, Exception-2: In Type-B with an automatic sprinkler system the length of the dead-end corridor shall not exceed 50-feet. 1. The 72-foot long corridor exceeds the maximum by 20-feet and is not allowed. 2. The 45-foot long corridor is allowed. 3. The common path 75-feet with sprinklers 4. New Door-C will have a panic device and exit sign on the 72-foot corridor side. 5. New Door-C will NOT have panic hardware or an exit sign on the 47-foot corridor side but will have a lever handle. The Kaiser Clinic is Type-B and is fully sprinklered throughout. To resolve the 72-foot long dead-end corridor, we propose the new locked Door-C have a "delayed egress" system that will permit exiting into the 45-foot long corridor. The delayed egress door is allowed under both: 6. IBC 1010.1.9.7 7. NFPA 101 "life safety code" 7.2.1.6.1 The IBC states: Delayed egress locking systems shall be permitted to be installed on doors serving any other occupancy except Group A, E and H in buildings equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1 or an approved automatic smoke or heat detection system in accordance with Section 907. The locking system shall be installed and operated in accordance with all of the following: 1402 Third Ave, Suite 200 / Seattle, WA 98101 /T206652,0722/F206340,2266/www.salus.archi
