INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for Phase II of
the 30 inch Force Main Relocation Project from 11th Street to 12th Street. There will be
one remaining phase to this project. Phase III will be between 7th and 9th Streets, on
Washington St.
BACKGROUND
In 1969 the existing 30 inch force main was constructed from the Cedar Street lift
station to the Terminal Street lift station.
The route went through the former A.Y. McDonald site, the former City Public Works
site, and the Alliant Energy site. During the early 1990's highway 151/61 was
constructed through Dubuque. During the highway construction portions of the 30 inch
force main were relocated and the portion running through the A.Y. McDonald site was
abandoned. However the portion running through the old Public Works Site and the
Alliant Energy site remained in place.
In October of 2011, the City experienced a significant failure in the existing force main.
Two breaks occurred simultaneously, one at the former Public Works garage site and
the other at the Alliant Energy site. After repairs were completed, a third break was
experienced at the former Public Works garage site. The cost to repair the breaks,
which occurred on the former Public works site, was significant as the site is a super
fund site. During the repair work some corrosion of the pipe was noted and it was also
found that when constructed the pipe was set on blocking prior to bedding, and the
blocking was not removed. The areas of corrosion and the failed sections of pipe were
near the old blocking that was found to be still in place. Soil and ground water
contamination has been identified on or near the existing 30 inch force main route that
may be a contributing factor to its deterioration.
The adopted budget for FY2017 includes $615,000.00 for constructing the Phase II and
Phase III, of the relocation project.
DISCUSSION
With the adoption of the FY2017 Five Year Capital Improvement Program Budget, there
will be a $640,683.88 balance to continue the Relocation of the 30 inch Force Main
around the former Public Works Garage Site.
A description of the force main relocation is as follows:
Construct Phase I: The first phase of the relocation project was completed in 2013,
ahead of the intermodal project start.
Construct Phase II (Current project): Phase II is the section of force main from the
Northeast corner of the 1 1th Street and Elm Street intersection, to the tie-in point
near 12th Street.
Construct Phase III (Future Proiect): Phase III is the section of force main on
Washington Street, 7h Street to ()"','Street. This section is planned to be completed
in conjunction with the reconstruction of Washington Street from 7th to 9th Streets.
Phase III would also include the tie-in, at 12th Street and 7th street, and the
abandonment of the existing force main through the old Public Works Garage and
the Alliant Energy Site. Completing phase III will complete the re-routing project.
