FROM:
Michael C. Van Milligen, City Mar;;gf)
Gus Psihoyos, City Engineer ./J ~
TO:
SUBJECT: Villa Street Retaining Wall
2004 Reconstruction Project
INTRODUCTION
The enclosed resolutions provide for the acceptance of the construction contract for the
Villa Street Retaining Wall Reconstruction Project.
BACKGROUND
As a result of the rain events on the weekend of May 22, 2004 the limestone retaining
wall adjacent to Villa Street, between Rush Street and Cleveland Avenue was
damaged. As a result of significant movement at the top of the wall and in the interest of
public safety, the wall has been dismantled and the embankment slope excavated to a
safe condition.
Due to the Presidential Disaster Declaration for Dubuque County, the Villa Street
Retaining Wall Reconstruction Project is eligible for FEMA funding. FEMA funding will
provide 75% Federal reimbursement, 10% State reimbursement with the remaining 15%
as the City's cost share.
The Villa Street retaining wall was reconstructed using a reinforced concrete foundation
grade beam which was anchored to the existing bedrock shelf and a conventional
reinforced concrete stem wall was constructed. The concrete stem wall was then faced
with limestone block to match the remaining wall sections to the north and south and is
in conformance with the city's native historic bluffs and character of the neighborhood.
The storm sewer system, asphalt roadway and sidewalk along the top of the wall were
also repaired as part of the project.
DISCUSSION
The Villa Street Retaining Wall Reconstruction Project has been completed by WC
Stewart Construction Company of Dubuque, Iowa, in the final contract amount of
$324,416.69, which is a 14.3% increase from the original contract in the amount of
$283,952.79.
The reason for the increase in cost associated with the Villa Street retaining wall
reconstruction contract, resulted from change orders to the original project scope of
work to address unexpected subsurface conditions, which required design build
modifications to be implemented for the reinforced concrete pier and the rock bolt
anchorage system. Due to the delays, the contractor was authorized to work additional
hours and overtime as required get the project back on schedule to ensure that the
retaining wall construction was completed and the supported roadway was in-service by
the time the winter season arrived in December 2004.
RECOMMENDATION
I recommend that the City Council accept the improvements and the final contract be
established at $324,416.69.
