Tigard, Oregon Items 1 Occupancy, 2 Construction Type and 3 Area The existing building was built in 3 phases as follows: Phase 2 - Classrooms Built in 1999, occupancy group A3 and E3, 6632 SF, type VN construction with full smoke detection and alarm system. This addition was separated from the previous 2 additions by a 2 hr. area separation wall ( grid G on the current plans ). No work is to be done in that portion of the facility. Phases 1 and 3 Auditorium, kitchen, mechanical rooms, toilet rooms and classrooms, built in 1976 and 1987, original occupancy group B3 ( now fits A3 occupancy description ). 9114 SF, type VN construction with full smoke detection and alarm system. Current Addition Auditorium ( worship space ) and lobby addition, remodel of toilet rooms, lobby and kitchen in areas of previous phases 1 and 3. A2.1 occupancy. 8,692 SF addition + 9114 SF phase 1 and 3 = 17,806 SF total. Type VN construction, fire sprinklered in lieu of 1 hr. at entire building ( except phase 2, separated by 2 hr area separation wall), with full smoke detection and alarm system. Capacity of auditorium, room 104, including room 105 = 6,586 SF / 7 SF per occ.= 940 occupants maximum ( UBC Table 10A, use 3 ). Capacity of multi - purpose room, #130 = 1,652 SF / 7 SF per occ.= 237 occupants. Capacity of offices, rooms 121, 123, 125, 126 = 976 SF / 100 SF per occ. = 9.7 occ. ( Table 10A, use 23 ). Capacity of classrooms, rooms 109, 129, 131, 132, 133, 139 = 1,688 SF / 50 SF per occ. = 34 occupants ( Table 10A, use 7 ). All other spaces, rooms 100, 101, 102, 103, 103, 107, 108, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 122, 124, 127, 128, 134, 135, 136, 137, 138 = 690 SF / 50 SF per occ. = 139 occupants ( Table 10A use 30 ). Item 8 Roof Construction Class B composition shingles on plywood sheathing and pre - engineered trusses or truss joists at the auditorium. Fully adhered EPDM class 1 roofing, over 1/2" Dens -Deck roof board FMRC class 1, plywood sheathing and truss joists at the lobby. Item 9 Draft Stops Attics will be fire sprinklered as part of this project. There are no attics over 9000 SF and there is no horizontal dimension over 100' ( UBC 708.3.1.2.2, Exception ). There are no floor /ceiling assemblies. Item 11a Area Separation Walls As noted in comment 1,2 & 3, the 1999 classroom addition was separated from areas involved in this project by a 2 hr. area separation wall. No work is being done in the classroom area and no changes are being made to the area separation wall. The wall construction consists of 2 layers of 5/8" type x gypsum board on wood frame construction per UBC Table 7 -B, Item 17 -1.5 for 2 hr. rated construction. Doors are 1 1/2 hr. rated and are provided with smoke detector hold - opens. Item 17 Stairs There are 3 existing interior stairs, 2 from mezzanine 138 and 1 from lobby 118 to hallway 124. These are all of adequate width and no changes are being made to them. There are 4 new exterior stairs. One is from the parking lot to the north entry patio, one is from the south entry patio to the parking lot, one is from the auditorium side aisle exit to the walk adjacent to the west parking lot and one is from hallway 102 to the landing at the top of the baptistry. All are of width as required by UBC. Item 18 Ramps There are 2 interior ramps, one existing at hallway 111, one new at hallway 102. Both are of width as required by code. The new ramp at hallway 102 is at maximum 1:12 slope. There is one new exterior ramp, at the south covered walkway, with a maximum slope of 1:20. Item 19 Interior Finish Class Toilet rooms are specified to receive vinyl wall covering, flame spread class 2 ( Spec. section 09950 ). The east wall of the auditorium is specified to have acoustical treatment consisting of 1 1/2" thick mineral wool sound deadening boards and class 2 fabric covering ( spec. sec. 09950). • The lobby ceiling is suspended acoustical tile, class A, flame spread 25 or under. All other new walls and ceilings are painted gypsum board. Item 20 Exits Auditorium, room 104, maximum occupancy is 940 ( see item 1 ). Per UBC Table 10 -B, "all other uses ", "other egress components ", 940 occ. X .2 = 188 inches of egress width required. Exits opening directly to the exterior of the building equal 216 inches of egress width. An additional 144 inches are provided through the lobby. Exits are separated apart over 1/2 the diagonal dimension of the area served. Multi- purpose room 130 ( existing auditorium ) has a maximum occupancy load of 237 ( see item 1 ). 237 occ. X .2 = 55.6 inches required egress width. There are 2 existing exits opening directly the exterior, that are equal to 72" of egress width. In addition, there are another 72" of egress width to the lobby, which provides exits directly to the exterior. Exits are separated apart over 1/2 the diagonal dimension of the area served. Office occupancy load is 9.7 and the adjacent workroom is 1.7 for a total occupancy load of 12 occupants. One exit is required under 30 occupants. This is provided through the hallway ( an intervening room ) which provides direct access to an exterior exit. All other spaces in the new and remodeled existing portion of the building require only one exit and are provided with exit paths through only 1 intervening room, which provides direct access to an exterior exit. Item 27 Electrical Steel conduit is to be used above ground, PVC conduit below ground or in concrete slabs. Item 28 Platform There is a platform in the new auditorium, room 104, and a raised floor area accessing the platform and baptistry in hallway 102. All voids below the floor sheathing in those areas will be filled with insulation. Item 30 Other There is a Knox Box indicated for installation on the exterior exit patio, adjacent to door #3 from lobby 108. Item 30 Alternate Materials and Methods As reviewed with Eric McMullen and Brian Blalock 10/31/03, there were two approaches to the auditorium addition. The first would be to separate the addition from the original type VN building with roll -up fire doors and a 2 hr fire separation wall, make the addition type V 1 hr and leave the original building as -is. The alternative would be to consider the entire building as A2.1 occupancy, type V 1 hr, with fire sprinklers in lieu of 1 hr construction. With this alternative, per UBC Table 5B the allowable area would be 10,000 SF basic + 50% for separation 2 sides = 15,750 SF. With an actual area of 17,806 SF, the building as proposed would be 2,056 SF over allowable. The alternate method approved during that discussion was that a full smoke detection and alarm system would be installed to offset the area over the code allowable. This, combined with fire sprinklering of the new and existing building was felt to provide greater life safety than the first alternative and is what is shown on the permit application drawings.
