DUBUQUE SOUTHWEST ARTERIAL
SUPPLEMENTAL AGREEMENT NO. 5
DESCRIPTION OF SCOPE MODIFICATIONS
SEPTEMBER 13, 2010
a. Delete Bridge on Ramp D Over Granger Creek
b. Delete Bridge on Loop B Over Granger Creek
c. Modify Hydraulic Modeling and DNR Permits
Attachment A
The Scope modifications described herein pertain to the final design phase of the Southwest Arterial project
in Dubuque, Iowa. The original Scope of Services included the final design of the Southwest Arterial in
accordance with the preliminary plans which were completed in March 2008.
During the course of the final design, several modifications to the previous preliminary plans have been
proposed by the City or Iowa DOT as a result of ongoing reviews and Value Engineering activities. The
following tasks describe the changes in the Scope of Services for the final design.
Task 1. Modify Bridge Designs at U.S. 151/61 Interchange. This task represents a modification to
Task Nos. 94, 95 and 98 in the original Scope. This task includes a re- evaluation of the four bridges over
Granger Creek, including hydraulic modeling, evaluation of various design alternatives, coordination with
the City and Iowa DOT, and changes in the final design. As a result of the studies, the previously proposed
bridges on Ramp D and Loop B will be replaced with a multiple reinforced concrete box culvert at Granger
Creek. The bridge on the Southwest Arterial over U.S. 151/61 and Granger Creek will be a 4 -span PPCB
bridge, as currently proposed. The following subtasks are included:
d. Add Multiple Reinforced Concrete Box Culvert Under Ramp D and Loop B. The culvert will be a
standard triple 12'x12' RCB culvert, approximately 350 feet long. The culvert will use standard
wings and headwalls. The alignment of the culvert will be straight (no bends /kinks, etc.), and the
grade along the length of the culvert will be constant (no drops, etc.). The camber will be provided
by Terracon.
e. Additional Coordination, Conference Calls and Meetings Pertaining to This Task
Task 2. Modify Retaining Wall Designs at Military Road. This task represents a modification to Task
No. 99 in the original Scope. Upon completion of the soil borings in the Military Road area, it was
determined that the originally envisioned tie -back retaining walls would not be suitable at this location.
This task includes the investigation and analysis of additional retaining wall options and modifications to the
final design. The structure on Military Road over the Southwest Arterial will be a 2 -span PPCB bridge, as
currently proposed. The following subtasks are included:
a. Investigate Alternative Retaining Wall Concepts, Including Mechanically Stabilized Earth (MSE)
Walls, Cast -in -Place Structural Concrete Walls and Various Options for Sloped Cuts. The
retaining walls investigations included analysis of temporary slopes during construction, temporary
tie -back measures for the construction zone, preliminary cost comparisons and conceptual design
layouts.
b. Additional Coordination, Conference Calls and Meetings Pertaining to This Task. This task
includes time for two additional coordination meetings, one meeting for aesthetics review and one
meeting for a final decision on retaining structure type.
c.1 Additional Surveying and Base Mapping to Cover the Added Length of Reconstruction
c.2 Additional Work to Prepare the Final Construction Plans
a.1 Develop Conceptual Plans
a.2 Traffic Analysis
a.3 Final Evaluation and Technical Memo Summarizing the Evaluation of Alternatives
b.1 Additional Survey and Mapping, As Required, for the Modified Design
b.2 Modify the Roundabout Intersection Design
b.3 Modify the Access Road Design
d. Additional Coordination, Conference Calls and Meetings Pertaining to This Task
Page 2
Task 3. Raise Profile Grade Near Military Road. This task represents a modification to Task
Nos. 63 -83 and Task Nos. 101 -123 in the original Scope. As part of the investigation of retaining walls
near Military Road, it was determined that a profile grade modification could reduce the height of the
retaining walls and reduce the construction costs in this area. The following subtasks are included:
a. Modify Mainline Southwest Arterial Plan and Profile. The profile and vertical curve near Military
Road will be modified to raise the grade of the mainline by approximately 4.5 feet.
b. Modify Military Road Preliminary Plan and Profile. The profile of Military Road must be raised
approximately 4.5 feet to provide the minimum vertical clearance at the bridge. To accomplish this
profile change, the length of the Military Road relocation and reconstruction will be extended
approximately 300 feet. This task includes the preliminary plan modifications.
c. Modify Military Road Final Plans. This task includes the additional work necessary to produce the
final construction plans for Military Road, accounting for the additional 300 feet of reconstruction
and the profile grade change. This task includes:
Task 4. Revise U.S. 20 Interchange Layout. This task represents a modification to Task Nos. 1, 5 and
all of the design tasks at the U.S. 20 interchange. As part of the intermediate Iowa DOT reviews, it was
determined that additional interchange concepts would be evaluated by the consultant and that the final
plans would be modified in accordance with a new interchange configuration. The following subtasks are
included:
a. Evaluate Alternative Interchange Configurations. This task includes the evaluation of
approximately three additional interchange configurations, including the layout of the Southwest
Arterial mainline, ramps, loops, bridges and side roads. This task includes:
b. Modify Road Design Plans in Accordance With the Selected Interchange Configuration. This task
represents the change in the level of effort required for completing the final construction plans, as
compared with the original Scope of Services. This task includes:
c. Modify Road and Bridge Designs. This task represents the change in level of effort to redesign the
Southwest Arterial road and the U.S. 20 ramps for the modified interchange layout as compared to
the original Scope of Services. Modifications to the bridge designs will be developed, as needed,
in a supplemental agreement once an interchange layout is selected. The roadway hours assume
a diamond interchange configuration with roundabout intersections on the Southwest Arterial.
e. Modify Hydraulic Modeling and CLOMR Submittal. This task represents the change in the level of
effort required for completing the hydraulic modeling and preparing the CLOMR submittal to FEMA.
Page 3
f. U.S. 20 Bridge Replacement Roadway Design. This task leads to the preparation and submittal of
final grading, drainage and paving construction plans for the segment of U.S. 20 immediately
adjacent to the proposed replacement bridges over the South Fork of Catfish Creek. The final
design will be completed in accordance with Iowa DOT Standards and Procedures for Local
Systems projects. The plans will be prepared on 11"x17" sheets at a scale of 1"=200'. This
scope is based on including the grading, drainage and paving work into one (1) contract that will
also include the partial construction of the Southwest Arterial.
Task 5. Additional Enhancement Analysis. This task represents a modification to Task No. 127 from
the original Scope. The original Scope for enhancements was based on the initial concepts developed
during the preliminary design stage. During the course of this project, consideration of additional
alternatives and options for roadway and bridge enhancements has been requested. This task includes
the investigation of various modifications to the conceptual enhancement plan, preparation of
three - dimensional graphics and other materials to illustrate the various alternatives, and modifications to
the final design. This task represents the change in level of effort for enhancement analysis and design, as
compared to the original Scope. The following subtasks are included:
a. Bridge Lightinq Evaluation, Including a Photometric Analysis and Investigation of Special
Architectural and Low - Energv Lightinq for the Bridges. This task will include LED lighting
conceptual design at prototypical bridges and roadway conflict points, including industry research,
location /height recommendations and product options.
b. Additional Graphics and Visualizations Pertaining to the Revised Enhancements. This task will
include detailed illustrations of prototypical overpass bridge enhancements, including lighting,
railings, form liners, colors, slope protection and landscape feature /plantings.
c. Develop Enhancement Concepts for Roundabouts. This task includes the development of
landscaping and enhancement concepts for the interior of the roundabout intersections. Five (5)
roundabout intersections are included in this task, to be located at the U.S. 20 and U.S. 151/61
interchanges. This task will include programming, conceptualization and documentation of
landscape features associated with the new roundabouts. This assumes no large -scale
"signature" type features would be included.
d. Additional Coordination, Conference Calls and Meetings Pertaining to this Task. This task
includes time for two additional enhancement coordination meetings.
Task 6. Modify Access Road Designs. This task represents a modification to Task Nos. 43-62 and
other design tasks in the original Scope. During the course of final design, several access roads have
been requested to be added or modified from the previous preliminary design. This task includes the
additional work necessary to add or revise the design of access roads. The following tasks are included:
a. Additional Access Road for Parcel 150 (Valentine) to Allow Access From the Farm Fields to the
Underside of the Bridge
b. Relocated Access Road for Verizon Located on Parcel 195a (O'Rourke). The design of this
access road was requested to be added due to an impact on an existing easement.
c. Modify Access Road to Barrington Lakes. This access road will be revised due to the modified
interchange at U.S. 20.
d. Modify Access Road to Cousins Road. This access road will be revised due to the modified
interchange at U.S. 20.
g.
Page 4
e. Modify Access Road to Tamarack Business Park. This revision was requested by the property
owner and includes the development of a preliminary plan and profile for the modified access road.
If this modification is accepted for the final plans, additional work will be required to survey and map
the revised access road location, obtain additional soil borings, redesign the roadway and modify
the right -of -way acquisition plats. These tasks are not included in the proposed Scope
modifications but will be covered by an additional supplemental agreement, if required.
f. Design Access Road for Archaeological Site 707. This task includes the field surveying and
preparation of a boundary easement and description for an access road approximately 0.8 mile in
length and traversing four properties.

Bob,
As discussed, below is a list of RDG related scope changes (some better understood than others) from our original
contract. We have kept this brief as requested with one sentence for each task /scope item and an approximation of
associated hours of effort. It is our understanding that this information will be utilized to receive informal
authorization to proceed with the owners. It is also understood that a supplement ultimately will be required and
this information will assist with developing the details of the supplement.
1. Lighting Design
a. LED lighting conceptual design at prototypical bridges and roadway conflict points including industry
research, location /height recommendations, and product options.
b. Anticipated Lighting Designer hours: 80 hrs
2. Bridge Enhancement Renderings
a. Detailed illustrations of prototypical overpass bridge enhancements including lighting, railings, form
liners, colors, slope protection, and landscape feature /plantings.
b. Anticipated Illustrator /Landscape Architect hours: 50 hrs
3. Roundabout Enhancement Design /Documentation
a. Programming, conceptualization, and documentation of landscape features associated with the new
roundabouts. Note: This assumes no large scale "signature" type features would be included.
b. Anticipated Landscape Architect hours: 150 hrs
In addition to the above three items, the following two items have the potential to significantly impact our existing
scope. No directives or decisions have been made regarding these items, so we simply are listing them as 'Potential
Scope Changes"
1. Signature Bridge Design /Documentation
2
a. If in fact the owner desires signature type bridge structures and associated enhancements, RDG may
be positioned to assist with this effort. The hours associated with this cannot be calculated without
more clarity to the scope.
2. Green Roads Process
a. If the owner chooses to pursue a process that incorporates Green Roads standards, metrics,
specifications, monitoring, etc, this would significantly impact our current scope. The hours
associated with this cannot be calculated without more clarity to the scope.

Subject: SW Arterial Scope Revisions
All,
As we continue with the SW Arterial final design, the city had Iowa DOT have been requesting us to
investigate several modifications to the original project description. We are trying to assemble a description
of any tasks that have changed from the original scope.
If you believe any of the activities that you are being asked to do are outside of your original scope, and will
require a scope modification, please let me know by Friday, May 25. We will need to know:
Description of the scope modification that is being requested
Describe why you believe the original scope does not cover this item
Include your estimate of staff -hours (by category) for each line item. This could be either an add -on
or reduction in hours, depending on what the scope modification is.
