The posts have been reevaluated <br /> and the sliding calculations reviewed. <br /> The attached calculations show that the 6x6 posts are still adequate. Review of the sliding <br /> calculations show that the resistance to sliding provided by the footings and the friction force of <br /> the slab still exceeds the load experienced by the subject structure. No revisions to the original <br /> design are required. <br /> Should there be any questions or comments please contact our office. <br /> Sincerely, M. <br /> 4C <br /> � � 44226 p �� <br /> �F�tST�R``' �� <br /> Andrew Gahan, PE s/OVAL ���' p� <br /> I1.1,��iJ}';f 1 <br /> EIi�ES 3-01- i <br />
