� <br />Evere[t Iiuilding Depart. .it <br />Page Two <br />Augnst 12, 1981 <br />• � . � <br />c) , We have submitted a revised detail (SK-1) which is'an approved <br />alternate to the cast-in-place joint. This welded connection ' <br />detail is being used on the wall panels on Grid 13. This detail <br />- meets our requiremenis provided a new detail (SK-2, which is -'�, <br />enclosed) is used at Che top of the panel. This detail replaces <br />[he (4) U6 chord tie bars which were left out of the panels. '!` <br />5. We cannot evaluate [he effect of the "consolidation of concrete by <br />hand mallet". <br />6, The wall panels that have been cut are as follows (per Gene 2lunter <br />�r10-81): <br />a� Panel U31 (Crid N, 6-7): 2" (2'-0" long) wa� removed to allow <br />the panel to sit on the £ooting at Grid 7. This has no effect <br />on the strength of the panel and is satisfactory. <br />b) Panel 039 (Grid 1, L.5-M): this panel was barely chipped at one <br />end to level panel onto footing. This has no adverse effect. <br />c) Panels i165, G6, G7 (Grid 7, A.3-B.3): 2'-0" x 2'-0" block-outs <br />were fiormed on the wrong side for the step tootings. 2'-0" x <br />2'-0" ooenin�s were [hen cut on the correct side and the block- <br />out vas cast with the pilaster. The walls presently are carrying <br />the major portion of their design load. If tliere is no distzess <br />showing at the present time tlie panels will be satisfactnry if the <br />• exterior grade is immediately placed and compacted [o the elevation <br />618.0' which is shown on A--L <br />7. See Item �14c. <br />8. The welclin� that has been done to date has Ueen of minor importance. <br />The cas[-in-place panel joint welding is really or convenience un� <br />docs not carry any load. Tiie (2) IFS cliord tie between panels also <br />carries no load because the laceral resistance for seismic anci wind <br />force� oP the Level 1 building is provided by purlin struts back to <br />Che retaining wull system on Cr:d 7. Since these welds essentially <br />carry no load, we will approve tl�e uninspected welds that have been <br />done. All future welding;tnust be inspected and Ue accomplished by a <br />W.A.II.O.

We have sludied and approved the chanre of the wall. pnnels from 6" to <br />5-1 2" A 5-1/2" panel mects our sCrucCural requirements.
