Thanks, Kirk Kirk Brooks City of Everett Bij7d g, Official Phone 425-257-8815 Fax 425-257-8857 From: Golden, Quinn [mailto:Quinn.Golden@gcinc.com] Sent: Tuesday, December 23, 2008 2:27 PM To: Souheil Nasr; Kirk Brooks Cc: Ambler, Blake; Ross, Don; Perrin, Stephen; Kettel, Ken Subject: Evaluation of Crane Loading on the 48-inch Water Main Souheil and Kirk, As previously discussed, Granite Northwest and its subcontractors plan on performing a large crane pick, of a pedestrian bridge for the Everett Station Phase 2 project, with the crane positioned over the City of Everett's 48- inch water main. Per our meeting with Souheil, on December 16th, a stamped geotechnical report is required that identifies the loading of the water main and measures that should be taken to protect that main. Attached is the Granite's geotechnical engineer's evaluation of the crane loading on the water main and the recommendations for protecting the water main. This evaluation was performed assuming the worst case scenario where the crane outrigger is positioned directly above the water main. This will not be the case during the pick, as it is expected that the outriggers will be off -set from the edge of the water main by at least 5 feet. Also attached are the outrigger loads as estimated by Ness Cranes and the pothole information on the water main that was performed in the presence of Randy Allen. I will get you a hard copy of this report, with attachments and a Granite Northwest cover letter on Monday, December 29th. As previously discussed, we are planning on performing the lest pick on January 9th and the final pick of the bridge on January 12th. Should you have any questions or concerns regarding the geotech's evaluation of the water main, please contact me at your earliest convenience. 12/29/2008
