At the concrete porte-cochere part of the building a slab on grade is provided. <br />All the vertical support elements bear on conventional continuous footings at the exterior of the building <br />and spread footings in the interior of the building. <br />This building was renovated in the 1990s to be used primarily as <br />an office building. At the time of renovation, existing transverse <br />shear walls were removed and new partition walls were added. <br />We were also informed that on interior shear walls at the <br />corridors, existing plywood was removed and replaced with <br />gypsum sheathing. <br />_ _.� <br />. :; <br />�21 S�or��;�orte�w����e lCoruc��. =i�!,-�a.n sys�em w,t�.•i�.�-] e��iltl�iig aMve. �; <br />, <br />: , , , �.; <br />N��� ����3 �, ��o , ; <br />soum wlnq w000 bu�ij�n,1 � <br />.

The Performance Level selected far this <br />facility is Life Safety. <br />We analyzed the building based on ASCE 31 Tier 1 analysis. Listed below are the deficiencies in the <br />building. <br />• Original wood shear walls were removed and replaced with partition walls (to the ceiling only), <br />reducing the lateral capacity of the building. <br />• The wood shear walls are not continuous to foundations. <br />• Collector elements to wood shear walls at the roof are not provided. <br />• The existing concrete moment frame columns have insufficient strength. <br />P,�cE 2 <br />
