SUBJECT: Phase III of the 30 Inch Force Main Relocation Project from 7t"Street to
12t" Street around the former Public Works Garage Site and the Alliant
Energy Site
DATE: May 1, 2018
INTRODUCTION
The enclosed resolutions authorize the public bidding for Phase III of the 30-inch Force
Main Relocation Project from 11t" Street to 12t" Street. Phase III will be constructed
between 7t" and 9t" Streets, on Washington St. Construction of phase III will complete
the re-routing project that eliminates the piping under the former public works garage.
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 remair�ed 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 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 $640,683.88 for constructing the Phase II and
Phase III, of the relocation project. Phase II was closed out in June of 2018, with a final
cost of$406,085.44 leaving a remaining balance of$317,361 to complete Phase III.
DISCUSSION
With the adoption of the FY2018 Five Year Capital Improvement Program Budget, there
i� a $317,361 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: The second phase of the relocation project was completed in
November of 2016. This phase of force main installed pipe from the Northeast
corner of the 11 t" Street and Elm Street intersection, to the tie-in point near 12t"
Street.
Construct Phase III: Phase III i� the s�ction of force main on Washington Street, 7tn
Street to 9th Street. This section was planned to be completed in conjunction with
the reconstruction of Washington Street from 7th to 9t" Streets. Phase III would also
include the tie-in, at 12t" Street and 7t" street. Construction of phase III will complete
the re-routing project and make the new force main operational. The complete
abandonment of the existing force main through the old Public Works Garage site
(Jule Site) and the Alliant Energy Site will be budgeted for in the FY 2020 budget.
