SUBJECT:
University Avenue Reconstruction (US 20 to University Avenue)
STP-U-2100 (623) - 70-31
Reinforced Concrete Box (RCB) Culvert Extension (Twin Box)
INTRODUCTION
The enclosed resolutions provide for the acceptance of the construction contract for the
reinforced concrete box (RCB) culvert extension of the University Avenue
Reconstruction Project.
BACKGROUND
The overall University Avenue Reconstruction Project (US 20 to University Avenue) is
intended to contribute to the improved flow of traffic and to decrease intersection
congestion along the US Highway 20 corridor in the western portion of the City.
The installation of the reinforced concrete box culvert is the first construction phase of
the project through which University Avenue is extended to the south to intersect with
US Highway 20 across from Theisen's driveway. This initial phase included
construction of a double-barrel, 12- by 12-foot box culvert and the grading of the
embankment for the future street.
Upon completion of this work, a follow-up construction phase will be necessary to
provide the pavement, traffic signals and other work necessary to complete the project.
DISCUSSION
The reinforced concrete box (RCB) culvert extension of the University Avenue
Reconstruction Project was completed by Tschiggfrie Excavating Co. of Dubuque, Iowa,
in the final contract amount of $1,248,555.21, which is a 10.6% decrease from the
original contract in the amount of $1 ,396,624.11.
I recommend that the City Council accept the improvements and establish the final
contract at $1,248,555.21.
BUDGET IMPACT

University Avenue Reconstruction Project is as follows:

Construction Contract
Contingency
Construction Engineering & Inspection
In April, 2005, the City Council approved a request for seeking additional funding from
the Dubuque Metropolitan Area Transportation Study (DMATS) for the completion of
Phase 3 of the University Avenue Extension of the US 20 Improvements Projects. This
request was made because of increased project costs associated with environmental
mitigation, property acquisition, wetland mitigation, and engineering fees. The request
from DMATS for the STP funds was $904,127.65, with an additional $226,031.91 from
City funds.
The 20% City match of $226,031.91 would be funded by the postponement of the
Center Grove/Cedar Cross Intersection Improvements (CIP 3001632) of $93,000 and
Stoneman Road Storm Sewer Extension Project (CIP 7201664) of $97,500, with the
balance of $35,531.91 from the annual appropriation for the Street Program (CIP
3001626).
Therefore, the project will be funded from the Capital Improvement Project 3001254,
University Avenue Extension to US 20, as follows:
Surface Transportation Funds (STP)
Street Construction Funds - City of Dubuque
$ 3,372,127.65

ACTION TO BE TAKEN
The City Council is requested to adopt the attached resolutions accepting the
improvement and establishing the final construction cost for the reinforced concrete box
(RCB) culvert extension of the University Avenue Reconstruction Project.
