RE: Phase III (7th to 9th) 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
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract for
Phase III of the 30-inch Force Main Relocation Project from 7t" Street to 9th Street.
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 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.
DISCUSSION
The tota! 30-inch Force Main Relocation Project was constructed in three phases from
7tn to 12t" Street. This Phase III portion of the project was from 7t" Street to 9t" Street
and is the focus of this memo.
Phase III of the 30-inch Force Main Relocation Project from 7t" Street to 9t" Street
project was completed by Top Grade Excavating, Inc. in the final contract amount of
$625,997.44. This is a 7% increase of the base bid amount of $584,117.80. The
increase is due to by-pass pumping, removal and replacement of the existing water
main, removal of a sanitary sewer manhole, sanitary sewer lateral repair and stored
materials.
Phase III section of force main on Washington Street from 7t" Street to 9th Street, was
planned and completed in conjunction with the reconstruction of Washington Street from
7t" to 9t" Streets. Phase III also included the final tie-in, at 12t" Street and 7t" Street to
complete the final tie-in of the three phased force main reconstruction project. The
completion of phase III finished the force main project, the new re-routed force main is
now operational. The 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.
BUDGETIMPACT
The summary of project costs for the Phase III of the 30-inch Force Main Relocation
Project from 7th Street to 9t" Street is as follows:
