September 22, 1992 Mr. Tim Tyler Buildinp Department City of Everett 3200 Cedar Street Everett, WA 98201 Re: Providence Hospital North Winp Expansio� Job No. 855 Dear Tim: I am writinp to confirm the information reviewed in our meetinp of September 12, 1992, with Steve Miller ar.d Chris Lark and our meetinp on September 17 with Steve Miller and Sam Preston. The state of Washinpton's "state•wide amendments" to the 1991 edition of the Uniform Buildino �ode S�andards, effective July 1992, has two revisions that could assist Pravidence Hospital in reducinp construction costs associated with the Notth Winp Expansion. The tirst amendment is VJHC 51-20-0551, which revises the required separation in buildinps of mixed occupancy. The result of this revision reduces the required occupancy separation between an open parking garage (8-3) and a Hospital (1� from four (4) hours to three (3) hours as required by Table No. 5-B. The eecond amendment which wil� benefit the Hospital is WAC 51-20-1011, which allows the use of the Life Safety Codes' "Suite concept". This revision permits one-hour corridor construction to be nonrated within the suite, providod that the eipht (8) listed conditions are addressed. In the days followinp the first meetinp, our office applied the effect of the suite concept to the North Winp project. We determined that, due to the mazimum of 10,000 square feet allowed ICondition No. 11, we would revise the main floor emergency depattment into a suite while leavinp the corridor construction of the first-floor surpery suite as submitted durinp the building permit review. The suite concept reduces costs in the following three areas: 1. Deletion of the required fire wall above the ceilinA and below the slab of the floor above. 2. Deletion of inechanical fire dampers where they penetrete the previously required fire walls. 3. Deletion of door hardware and associated UL Ratinps for openings within the corridor walls. This hardware includes door closers, mapnetic hold-opens, and smoke seals. In addition, tempered safety glass can be substituted for wire glass in relite openings. n reviewinp the contract locatiun of fire dampers to determine which could be deleted, we found that application of th� UBC Section 1706, Part (b!: Exception 3 and UBC Section 4306, Part (jl, Item 5, Exception can also allow the deletion of a number of fire dampers. 4206 Hoyt Avenue � Everett, Washington 98203 • 206/259-0868 • 20E/774-3341 • FAX 206/252-4334
