Signed Contract_Top Grade Excavating Change Order_Key West Dr Water Main Ext. THE CITY OF � Dubuque DUB E (A *America Ch Masterpiece on the Mississippi 2007.2012.2013 To: Michael C. Van Milligen, City Manager From: Bob Green, Water Department Mana E��tell Subject: Key West Drive Water Main Extension Change Order Date: June 10, 2016 Introduction The purpose of this memorandum is to request your approval of a change order with Top Grade Excavating, in the amount of $79,757.00, to construct a water main loop along Lake Eleanor Drive from Timothy Street to Key West Drive. Discussion The City recently entered into a partnership agreement with Dubuque County, as part of their Key West Drive Road Improvement Project, in order to construct a water main along Key West Drive from Oregon Street to Military Road. The requested change order would allow for the construction of a continuous loop system, along Lake Eleanor Road from Key West Drive to Timothy Street. This extension will provide a link to the proposed Southwest Arterial as well as act as second feed line to both the Airport and the Twin Ridge subdivision area. The Engineer's estimated cost for this project was $92,907.10. Top Grade Excavation's bid for the proposed water main loop is $79,757.00; which is $13,150.10, or approximately 14%, less than the engineering estimate. Monies were budgeted in CIP 7402633 -73211 (current available balance $142,860.00) to support this project as well as other improvements. Action It is our recommendation, with your approval, to proceed with Top Grade Excavating's change order, in the amount of $79,757.00, to construct a water main loop along Lake Eleanor Road. Staff and I are available at your convenience to discuss and answer any questions you may have along with this project.
