3. Exterior wali protection is required, the assumed property line (between units} <br /> should be shown. Fire resistive construction will be required to be maintained for the <br /> supporting structure of the exterior walls. <br /> Please note indicated conforming designations. <br /> Type I FR Construction <br /> 1. Any masonry or concrete wall which supports more than 200 pounds per lineal foot <br /> superimposed load, or any such wall supporting its own weight for more than one story <br /> is defined as a bearing wall per UBC Section 224. Based on that definition, the <br /> following comments apply: <br /> a). The westem exterior wall supports its own weight for more than one story and <br /> should therefore be shown as a minimum of 2 hour fire-resistive construction. <br /> Agreed, please note revised designaHon. <br /> b).The eastem exterior wall shouid be shown not to support more than 200 pounds <br /> per lineai foot of superimposed load. <br /> Agreed, please note that this wall is inNll only and is not required to support any <br /> load other than iYs own weight. <br /> We have decided for the sake of construcdon simplificetion to revise the <br /> designation to a two hour rated wall. <br /> Nodsontal Exlts <br /> A horizontal exit is defined as an exit from one building into another building per <br /> Section 10012. Area separation walis are used in this building to allow, in effect, iwice <br /> the area that would otherwise ba permifte%i based on the type of construction chosen. <br /> Each portion of a building separated by one or more area separation walis which <br /> complies with Section 504.6 may be considered separate buildings as stated in <br /> Section 504.6.1. Two buildings have therefore been created side-by-side on the same <br /> property. <br /> Either one of these buildings would be required to have complete exiting systems in <br /> place, in this case; two exits at each floor as requ'*ed in Section 1003.1. These <br /> buildings share the exiting system, however, by the use of horizontal exits, which <br /> provides the concept of exitlng from one building to another to be employed. <br /> Horizontal exits are therefore not solely derived from requirements based on occupant <br /> load, quantiry of exits and travel distance, but also on the actual arrangement of exits <br /> themselves. <br /> , �� � ��,,:�,�,�� ,,,, <br /> I�r, li1,11 VIIC��If;1 Cl i, ii �o i����„r r:,, <br /> � . .,� . <br /> ". , � ,,����� � �-,,,�., <br /> Ifl�fRl'i,�1'�i�i; I'�it���RD��GIIGRI�iCD��I�I�III�a�D�if,l�� IRI;IIITCCTGRC III������1��GIlI�RI�R��IGI�GRIPNICD��IG�1��11�I;�D�IGI <br />
