Please include the following item on the City Commission Agenda for consideration at the June 21, 2011 meeting:
Award the construction contract for Bid No. B1123; Project UT0810DS – Phase II of Watermain Replacement Program; Kentucky Street from 12th to 19th Street, 9th Street from Tennessee to Vermont including alternates 1, 2, and 3 to the low bidder RD Johnson Excavating in the amount of $1,423,333.00 and authorize the City Manager to execute the contract.
Consistent with the City Commission’s direction during the 2011 Budget Sessions Department of Utilities Staff continue to monitor and control expenses in relation to actual revenues. As these are evaluated, sources of Capital Project Funding are being identified to carry out the City Commission’s stated goal of executing priority Capital Projects even in the current economic climate. The reasons for executing this project are outlined in the memo below.
Project Description
Replacement of the existing watermains along 9th Street from Vermont Street to Tennessee Street and along Tennessee Street across the 9th Street right-of-way (see attached exhibit). The existing watermain along 9th Street is 1916 12” diameter cast iron, the existing watermain along Tennessee is 1912 12” cast iron and 1886 14” cast iron. This project was approximately 40% designed by BG Consultants during the 2005 – 2007 Massachusetts Street watermain replacement projects. These existing plans have been updated and integrated with the current project design.
Replacement of the existing watermains along Kentucky Street from 12th Street to 19th Street (see attached exhibit). The existing watermain along Kentucky Street is 1886, 1916 & 1922 10” & 12” cast iron. The watermains at several of the cross streets along this stretch of Kentucky also date back to the late 1800’s early 1900’s and have been identified as add-alternates to this project as discussed below. Attached are photos of the Kentucky St watermain showing the leaking joints during winter conditions and the interior condition of the pipe.
Staff evaluated watermains adjacent to the alignments in 9th Street and Kentucky Street as identified above and developed the following add alternates to be bid as part of phase II of this project, an exhibit is attached for reference:
Alternate #1, 18th Street: Tennessee to Kentucky, 8” Cast Iron (1922)
Alternate #2, 13th Street: Tennessee to Vermont, 8” Cast Iron (1938)
Alternate #3, Tennessee Street: 9th to 10th Street, 12” Cast Iron (1912)

Per the terms of the Bond these funds must be expended prior to August of 2012 to maintain their non-taxable status and will be expended prior to the utilization of the remaining 2007 Bond proceeds. The available project funding for construction is $1,460,317.00, which exceeds the total low bid including alternates 1, 2 and 3 of $1,423,333.00.
