I 'd like to respond to sevEral of the items from yaur letter. 1. The double 8 inch CMU walls with a 2-3/4" physical air space along grid line 4 provide an equivalent concrete thickness of approximately 6.5", thereby creati.ng a 4 hour fire separation wall and allvwing this project to be considercd as 2 buildings (UBC 505e) . There are no openings through this separation wall < Building 2410 is a two story building as the second floor does not match the definition of a mezzanine (UBC 1716(3) and 1716 (4) ) , nor does the first floor match the definition of a basement (UBC 403-basement, 420-story', and 420-story, first) . Therefore, building 2410 may be twice the allowable size for a type V-N bui.lding per table Sc, or 16,000 SF., total (UBC 505b) . This �uilding has 7, 450 SF on the first floor and 3 , 750 SF on the second floor. Building 2420 is separated on 2 sides by public ways or yards great�r than 20 ' in width and therefore may be increased in size by 1-1/4 percent for each foot by which the minimum �aidth exceeds 20 ' up to a 50$ maximum increase in required size per table 5c. Min width of separation - gg � Less 20 ' width = _20 � Total yard/pub width for calculation = 69 ' Calculated allowable increase - 69 ' X 1-1/4$ = 86. 25% Maximum increased size = 8, 000 SF X 50$ = 12, 000 SF Actual Bui2ding size = 10, 000 SF SE4TTLE ANCHOFlAGE
