City Engineer Gus Psihoyos recommends City Council approval of a supplemental
agreement with AECOM Technical Services, Inc. for the final engineering design phase
of the Southwest Arterial Project, subject to the concurrence of the Iowa Department of
Transportation.
On February 7, 2011, the City Council approved the recommendations of the Value
Engineering evaluation and authorized the proposed design modifications be
incorporated into the Final Design phase of the Southwest Arterial Project.
Although the proposed changes have identified potential decreases in construction cost
and has increased the overall value of the project, the approved design modifications
will require significant plan changes, which will require the design team to take a step
back in the design process and re- initiate the preliminary design phase.
The $345,600 is available in the project budget.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION
BACKGROUND
DISCUSSION
Dubuque
All-America City
2007
The enclosed resolution authorizes the Mayor to execute a supplemental agreement
with AECOM Technical Services, Inc. (AECOM) which approves revisions to the original
scope of services to the Consultant Professional Services Contract to complete the final
engineering design phase of the Southwest Arterial Project.
On March 2, 2009 the City Council approved (Res. 87 -09) the selection of AECOM
(Waterloo, Iowa) to provide the final engineering design for the Southwest Arterial
Project. The initial agreement included: the final engineering design; preparation of
construction documents; geotechnical investigation; architectural and landscape
enhancements; archaeological and cultural resources mitigation; public involvement;
agency coordination and construction engineering services.
On February 7, 2011, the City Council approved the recommendations of the Value
Engineering evaluation and authorized the proposed design modifications be
incorporated into the Final Design phase of the Southwest Arterial project.
The most significant design modifications will be incorporated into the SW Arterial / U.S.
20 / Seippel Road interchange area. This change includes: use of roundabouts;
changes to the ramp layouts; changes to the access road layouts, eliminate the need for
a cross -over bridge; reduction in mass earthwork quantities; and eliminating the need to
purchase three (3) properties along Cousins Road. The potential design modification
savings are in the magnitude of $6.2 million.
Although the proposed changes have identified potential decreases in construction cost
and has increased the overall value of the project, the approved design modifications
will require significant plan changes, which will require the design team to take a step
back in the design process and re- initiate the preliminary design phase.
The preliminary re- design efforts will quite extensive and will require the design team to:
design a new interchange layout; perform detailed traffic analysis; develop new
roundabout intersection details; investigate design variations for the bridges; coordinate
reviews with Iowa DOT staff; evaluate potential impacts to right -of -way acquisition;
evaluate potential impacts to wetlands; historic and cultural resource areas; review
watershed and stream crossing impacts, and environmental clearance compliance.
As a result of the proposed design and plan modifications, the original scope of services
needs to be revised to reflect the following changes:
• Investigate additional options for the ramps and access roads at the US 20
interchange.
• Modify the Barrington Lakes Connector Road to intersect with the Southwest
Arterial at a new third roundabout intersection.
• Roundabout Intersection Design
• Investigate bridge design enhancements and lighting at U.S. 20 / Seippel Road
Interchange, and modify bridge designs to incorporate selected enhancements.
• Modify profiles, cross sections, drainage design and surface stabilization design
in the vicinity of shale cuts.
• Modify roadway design north and south of Military Road to include stabilized cut
slopes in lieu of structural retaining walls.
• Modify design of Military Road Bridge to include wrap- around retaining walls at
the abutments.
• Investigate additional options for the Olde Davenport Road connection.
• Modify design of wetland mitigation site to meet new Corps of Engineers rules
and to compensate for additional wetland impacts from other design changes.
• Revise or provide new right -of -way plats and descriptions in association with the
design changes.
• Investigate bridge design enhancements and lighting at U.S. 151/61 interchange,
and modify bridge designs to incorporate selected enhancements.
• Investigate roadway enhancement options for the revised design elements,
modify the enhancement concept plan, and provide final design of selected
enhancements.
• Provide additional soil borings and geotechnical analysis related to the design
changes.
• Provide additional Phase I archaeological surveys related to the design changes.
Per the terms of the Consultant Professional Services contract and the conditional
requirements of the federal aid funding agreement, if the Consultant is of the opinion
that any work directed to perform is beyond the scope of said contract, and constitutes
"Extra Work ", it shall promptly notify the City in writing to that effect. Unless written
approval for "Extra Work" has been secured in advance of performing said work from
the City, the Iowa DOT and the FHWA, said work will be ineligible for federal aid
participation. The Consultant Professional Services - Supplemental Agreement
authorizes AECOM to provide the revised scope of services to continue to advance the
completion of the final engineering design phase in accordance with Iowa DOT and
FHWA procedures and requirements.

Bob and Kent,

At our meeting on Monday, November 1, 2010, we were verbally authorized to proceed with switching the final
design of the English Mill Road bridge from AECOM to WHKS. Based on this approval, WHKS is proceeding with the
design.
For our files, we are requesting your written confirmation of this authorization by return email.
This change will not affect the overall cost of the engineering agreement, but will only involve transferring the work
and budget from AECOM to WHKS. We are planning to include this change in the next supplemental agreement for
the design contract.
Thanks for your help, and please let me know if you have any questions.

Bob and Kent,
Attached is a proposed scope revision from Terracon for changes to their work at U.S. 20 and U.S. 61/151. We are
requesting your approval for Terracon to proceed with the revised soil borings and geotechnical work for the RCB
culvert at U.S. 61/151 and for the dual bridges on U.S. 20. This scope revision will be added, along with other scope
revisions, to the next supplemental agreement.
Please let us know by return email if you approve this request.
Thanks for your help.
