INTRODUCTION
The attached resolution authorizes the award of the construction contract for the
Marquette Place Sanitary Sewer and Water Main Reconstruction Project.
BACKGROUND
City records indicate that the sewer and water main that service the fifteen homes on
Marquette Place were installed in 1918. The public utilities that serve the homes were
installed at the rear of the properties. Because the sanitary sewer and water mains are
behind the homes, over the years private decks, building additions, storage sheds,
landscaping and fencing have been constructed near or over the two public utilities, which
have led to maintenance issues for these utilities.
Sanitary sewer backups have caused the sanitary sewer line to be added to the Public
Works Department regular maintenance schedule. Following the initial sanitary sewer
backup, an inspection revealed that the 8-inch diameter clay pipe had deteriorated to the
Pxtent that replacPment was warranted. In addition, private property additions or
structures, etc. were built over the sewer line, or in close proximity to the City utilities
making repair virtually impossible in its current location. Also, many of the private sewer
and water services are located where they would be impractical to repair. In addition, to
the above issues, the sanitary sewer along Marquette Place has historically had elevated
levels of I&I and it was identified for replacement as part of the corrective action plan
under the US EPA Consent Decree. Therefore, it was concluded that the sewer and water
mains must be reconstructed and relocated to a different location to alleviate the current
inflow and infiltration issues and allow for the future maintenance of the public utilities.
DISCUSSION
The Marquette Place Sanitary Sewer and Water Main Reconstruction Project will provide
for the replacement and relocation of the existing sanitary sewer and water mains. As
part of the project all of the 8-inch clay sewer pipe will be replaced with approximately 708
feet of 8-inch diameter PVC (polyvinyl chloride) sanitary sewer pipe which will service the
fifteen homes in the area. Also, all the brick manholes will be replaced with eight concrete
manholes.
The water main portion of the project will include the replacement of all the existing water
main with 928 feet of six-inch C900 piping. The project will also include the replacement
of one fire hydrant. The current water main that services the hydrant is located so close to
a building foundation that it would be impossible to repair in its current location.
The current City water main that services Marquette Place runs up a steep embankment
from Queen Street. This project includes installing a redundant water main to not only
facilitate the construction of the project but will also add a water main that will help assure
the homes will be provided with water in the event of a water main break occurs in the
area.
The Engineering Department has met with the property owners as a group three times to
discuss the project. In addition, the Engineering staff has had multiple meetings and
individual telephone conversations or on-site visits with all the property owners regarding
the location of the new utilities. These meetings detailed the project and discussed the
existing, proposed and final location of the two City utilities along with the effects of the
relocation to the owner's private property. Also discussed were the new easements that
would be required along with how the new location would affect the properties
landscaping items such as trees, shrubs, fences, patios, etc. Also, several properties
have storage sheds that will need to be moved or reconstructed as part of the project.
Because of the new locations of the public sewer and water mains, the services will need
to be lengthened and reconnected. Many of the property owner's services will be difficult
to replace because of the fact that previous home owners constructed decks or significant
obstacles over or near the existing City sewer or water main. Also 9 of the 15 of the
homes have private lead water services that supply water to their homes. Each of the
nine owners are now aware that their homes are serviced by a lead water service and
know that this is the ideal time to replace the lead lines. To date all the property owners
have agreed to replace their private lead water service. The City will bid the replacement
of the nine lead water services. The replacement cost will be assessed to the individual
property owners as a voluntary assessment.
BID RESULTS
The City received six sealed bids on March 7, 2019, for the Marquette Place Sanitary
Sewer and Water Main Reconstruction Project. Two of the six bids were determined to be
non-responsive by the City's Attorney's Office. Top Grade Excavating, Inc. of Farley, IA,
submitted the low, responsive bid in the amount of $357,856.25 which is 0.8% over the
estimate of probable cost. This bid includes City sanitary sewer, City water main and
private voluntary assessments. A summary of the bid proposals received is as follows:
