Our reqs are 2.5` like the na rative details. the drawing only has ONE <br /> depth, 12" shown. NOT ENOUGH, <br /> please modify the drawing Mushroom Cap for Pressure Grouting details and clearly show the <br /> depth with the 24" auger to be 2.5-feet, the total depth as 3.0-feet, and the casing stubbed up <br /> 6-inches. also show the top of the overspilled cement to be NLT 1.5-feet below ground surface <br /> (or a minimum thickness of 1.5-feet). you may bring it up to 6-inches below the surface if you <br /> wish, but the minimum amounts and depths MUST be shown correctly if you provide a figure. <br /> may I recommend in the future with your submittals to the EHD, please paginate the report, <br /> assign paragraph numbers, and assign numbers tot e figures. this will allow a clearer <br /> explanation if the EHD has to require modifications to your submittals. <br /> thanks <br /> Mike Infurna. <br /> From: Michael Vlach [mailto:michaelvlach@comcast.net] <br /> Sent: Wednesday, July 13, 2011 8:35 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Olivarez Letter <br /> Thanks <br /> -Mike <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com} <br /> Sent: Wednesday, July 13, 2011 7:51 AM <br /> To: Michael Vlach <br /> Subject: RE: Olivarez Letter <br /> go ahead and write and send in the report <br /> 7/13/2011 <br />
