DATE: August 1, 2012
City Engineer Gus Psihoyos is recommending acceptance of the construction contract
for the 7th Street Retaining Wall Reconstruction Project, as completed by Portzen
Construction, Inc. in the final contract amount of $426,576.72, which is 21.4% over the
contract amount of $351,336.20. The project cost increase is due to additional
watermain and sanitary sewer work. The project was extended a short distance to
include the replacement of additional watermain, valves, and services. This additional
watermain work allowed for the watermain to be fed from two locations.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

The enclosed resolutions provide for the acceptance of the construction contract for the
7th Street Retaining Wall Reconstruction Project.
BACKGROUND
On October 3, 2011, the City Council authorized (Resolution 328 -11) emergency repairs
to the public retaining wall along 7th Street and the associated street pavement. The
project provides for the: reconstruction of the retaining wall; resurfacing of 7th Street in
the area of the wall; replacement of the curb and gutter along the repair; and the
replacement of the guardrail along the retaining wall.
DISCUSSION
The 7th Street Retaining Wall Reconstruction Project was completed by Portzen
Construction, Inc. of Dubuque, Iowa, in the final contract amount of $426,576.72, which
is 21.4% over the contract amount of $351,336.20. The project cost increase is due to
additional watermain and sanitary sewer work. The project was extended a short
distance to include the replacement of additional watermain, valves, and services. This
additional watermain work also allowed for the watermain to be fed from two locations.
Additionally, the sanitary sewer main was going to be left in place and rehabilitated by
lining the pipe. As construction progressed, the sewer main was exposed and found in
poorer condition than originally thought. The sanitary sewer section was replaced to
avoid future issues under the new street.
RECOMMENDATION
I recommend that the City Council accept the improvements and establish the final
contract at $426,576.72 for the 7th Street Retaining Wall Reconstruction Project.
BUDGET IMPACT
The 7th Street Retaining Wall Reconstruction Project was an unfunded project when the
wall failed. In order to fund this project, other Capital Improvement Project (CIP) funds
were required. Some unused funds were required from the Sunset Ridge reconstruction
project.
The project cost summary for the 7th Street Retaining Wall Reconstruction Project is
summarized as follows:
Award Final
Construction Contract $351,336.20 $426,576.72
Contingency 35,133.62 0
Construction Engineering 57,970.47 36,428.84
Total Project Cost $444,440.29 $463,005.56
The project funding summary is as follows:
CIP No. Fund Description Fund Amount
1021041 Curb /Catch Basin Replacement $74,999.00
3001027 Guardrail 65,999.00
