Arden Hills <br />Nick Landwer/URS <br />Frank Ticknor/ URS <br /> <br />From: Gregory Brown, PE <br />Arden Hills City Engineer <br /> <br />Date: January 5,2005 <br /> <br />Subject: Authorization to Advertise for Bids <br />Lift Station #4 & #9 Reconstruction Project <br /> <br />Background . <br />As part of the continuing rehabilitation of the sanitary sewer system for the City, the Council <br />authorized preparation of Plans and Specification for the Lift Station #4 & #9 Project on <br />November 29,2004. Plans and Specifications for this project have been completed including a <br />construc1ion cost estimate. <br /> <br />Project Description <br />Both Lift Station #4 and #9 are old "steel can" structures built in the early 1960's that have <br />deteriorated and are in difficult locations to access if problems arise. The method for <br />reconstruction of #4 and #9 will follow that of Lift Station #7 last year and Lift Station #3 in <br />1998. A bypass pump will first be installed from an adjacent sanitary manhole into the <br />forcemain to keep the system running during construction. The existing lift station structures and <br />control panel will then be removed and the new pumping system and electrical system will be <br />installed. The bypass is removed once City staff approves the system and the new lift station will <br />be brought on-line at that time. <br /> <br />The proposed work indicated here is based on final Plans and Specifications. The estimated cost <br />of construction to rebuild both of these lift stations is approximately $229,000 with the overall <br />Project cost approximately $263,350. The budget adopted includes $200,000 overall project cost <br />for this construction item. The estimate reflects inflation of construction costs through the 2004 <br />construction year. The Lift Station Reconstruction project is funded entirely under the Sanitary <br />Sewer Enterprise Fund which has a current balance of $1,138,151. <br /> <br />. <br /> <br />R:\31809733\DOCUMENTS\WORD\Auth for Ad 1-4-05l.S4&9.doc <br />
