We have found that the interior face of the concrete wall is covered with a mop-on waterp oof <br /> membrane.Short of sand blasting the interior side of the wall we believe that there is no effective way to proceed with the carbon fiber <br /> reinforcing system.The hospital and the contractor feel that sand blasting will create dust and noise problems and have requested that we <br /> investigate an alternative method of reinforcing the wall. <br /> Attached is our Structural Engineer's proposed alternate method of reinforcing the wall at the opening.The new system uses 14"steel plates <br /> and Kwik-bolts. <br /> The sketch is stamped by the structural engineer.The Engineer is requesting that the new detail receive special inspection during construction. <br /> Please feel free to call or email me regarding the above. <br /> Ross Brown <br /> 206-521-3502 <br /> rbrowndgf.com <br /> 1%, <br /> ode <br /> 0 St? 2 41�'��1 <br /> G\�V OF S EA as <br /> PBt% <br /> CITY OF EVERETT IT <br /> REVIEWED FC)R PER <br /> q/a� .gz- <br />
