deformation. The twist in the anchors ranged from as much as 90 degrees per 2.5-fect <br /> (anchors #8 and �10) to a minimum of 45-degrees in 2 feet (anchor#5). Based on the <br /> steel twisting, we expect that the anchors were installed to a torque of at least 5,500 ft- <br /> Ibs, which is greater than the required 3,900 foot-lbs on this project. <br /> The brackets used to jack up the house were CI50-0298 brackets with a working capacity <br /> of 40 kips each. In our opinion, this is adequate to support your house. <br /> In our opinion, these anchors will stabilize the portion of the house supported by them. <br /> As noted in our report, the deep loose soils extend farther to the east on the south wall but <br /> there doesn't appear to be any detrimental effects, probably due to the higher stem wall in <br /> that area. The soils encountered in our explorations were granufaz and therefore we <br /> expect settlement to have occurred as the structure was constructed and loaded the first <br /> time. "fherefore, w�e do not expect future settlement on the east end of the south wall. <br /> However, we recommend that you be observant and if signs of settlement occur in this <br /> area, you tahe steps to add additional anchors. <br /> 'Chank you for this opportunity to serve you. <br /> Sincerely, <br /> HWA GeoSciences > _p(�+� �• � �1 <br /> ����nF K'�Sy�!'6�. <br /> .h~ �` �Ci� ,� <br /> �; �� �!`�Y o , /(�./p'j� <br /> '' 7 � <br /> � ��,.:,; , <br /> � �i:•;�: _ <br /> I�/�i� N ., : '�� <br /> ,\R� �� I'.�'t <br /> Y�'�� �4 <br /> � _ -'��t� <br /> :.r <br /> "l_ ;,. ��. <br /> ;....,....,o„�'^`°:�',-....-! <br /> � -. , m�'.',� <br /> Susan Robarge Thomas Kinney, Ph.D., P.E.. <br /> Geotechnical Engineer Vice-President <br /> �3 <br />
