The fact that the bore and jack could be advanced a significant <br /> distance before refusing reflects that conditions along the majority of the <br /> bore and jack are similar to those encazatered by the original borings: <br /> however, these latest borings indicate that the contractor has encountered <br /> partially weathered rock and that alternative construction procedures will be <br /> necessary to complete the bore and jack. <br /> We-appreciate the opportunity to comment on this matter. If we <br /> may be of further service, please contact us at your convenience. <br /> Very truly yours, <br /> SSZE <br /> /47,71/ <br /> G David Garrett, P.G. <br /> N.C.
