It is our understanding that the sketches submiried rapresent the chenges you have made and intend to make to the slructure. The chanpes qenerally invdved ornNtlnp a poNon oi the upper level at the hiphest end of ihe sGudure and extending the poAion over the Aarage approximately two feet. Induded fn these chenpes were the insertion of sevarel beams which were avaflable on sRe. We were esked to deiertnine if these were su�aent for the IocaUons indicated. The changes made increased the gravity loading on two columns, both of which have been up-sized. We also found one location whet�e a beam Indicated on the plen had to be up-sized from(3)Dc10's to a glulam. At those IocaUons where the indicated beam is oversized,we have indicated the smellest beam which could be used at that location. We find that the changes made have not affected the lalerel slrength of the building. This is due to the fad that the proflle of the building has been reduced, presenting less resistance to the wind. At the same Ume,the strength of the shearvvalls has not been reduced. Should you have any questions ordesire addftlonal iMormation, please do nM hesitate to contect us. We trust this fulfills your request for engineerinp modifications, and in that regard, ft is Respeclfully Submitled, � Cq� -, ��C sy�y\ � �� U y �='' IJ Clayton M.
