construction documents; geotechnical investigation; architectural and landscape
enhancements; archaeological and cultural resources mitigation; public involvement;
agency coordination and construction engineering services.
The design team is currently completing the remaining final engineering design phases
and preparing construction plans for upcoming projects for the continued development
and advancement of the Southwest Arterial project.
The Consultant Professional Services - Supplemental Agreement includes revisions to
the original scope of services to reflect the remaining anticipated level of effort required
to advance the completion of the final engineering design phases in accordance with
the "grade four lanes/pave two lanes" project as outlined in the Memorandum of
Agreement and the Transfer of Jurisdiction between the City and Iowa DOT.
DISCUSSION
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", the Consultant 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.
As a result of additional design element changes, the original scope of services needs
to be revised to reflect the following task modifications that are required to continue to
advance the completion of the final engineering design phase:
• Changes related to revised three-lane design of Seippel Road to
accommodate the new Landfill Access Road just west of the proposed
US20 interchange.

B. WHKS Scope of Services
The Iowa Department of Transportation(Iowa DOT)has directed that the future access
road to the Dubuque Area Landfill be constructed to intersect with Seippel Road, west
of the proposed US 20 interchange. With the relocation of the Landfill Access Road,
auxiliary lanes will be required on Seippel Road at the proposed intersection. Because
WHKS has advanced the construction plans for the Seippel Road and the associated
design, the change to the Seippel Road typical section will require additional staff hours
in order to survey, redesign and develop plans for the revised Seippel Road.
WHKS's Scope of Services is modified to include the following tasks:
Survey
Task 1 - Seippel Road Resurvey. The grading and utility construction that has taken
place as part of the NHSX-032-1(38)--3H-31 project has impacted the project area and
requires additional topographic survey so that the project TIN file and earthwork forthe
Seippel Road redesign can be developed. The topographic survey performed by
WHKS will be in accordance with the IDOT "Office of Design Preliminary Survey
Specifications." The work tasks will include:
1) Administration, coordination and meetings.
2) Recover and verify, or establish, horizontal and vertical control.
3) Establish approximately five additional supplemental control points and bench
marks along survey limits as needed.
4) Topographic survey(cross section ground shots only)from approximately Sta.
51+00 (O.A.) to Sta. 74+00 (O.A.), approximately 2,300 feet long.
5) Initiate Iowa One-Call Design Request System for Quality Level C or D utility
locations and shoot existing utilities.
6) Office processing of DTM shots.
Survey Assumptions and Limitations
1) Cross sections along Seippel Road to be at 100-foot intervals, out left and right
125 feet from centerline.
eL=Com
Page 6
2) Cross section proposed Landfill Access Road 200 feet west of Seippel Road
out left and right 125 feet from centerline at 100-foot intervals.
3) Horizontal and vertical control will be tied to the existing SAP 0331 Control
Network on Project NHS-20-9(121)--19-31.
4) Bench levels may be required to replace missing project bench marks.
5) State Right-of-Entry procedures will be used to enter and survey on private
property. It is estimated that one property owner is affected.
6) Drainage area delineations on an aerial photo are not required. Drainage
areas from previous surveys or plans to be used.
Survey Deliverables
1) Unedited data collection files, topographic surveyfiles, Cfiles and I (Index)file.
2) Iowa One-Call Design Request System utility location logs.
3) MicroStation and GEOPAK files of the processed survey data.
Seippel Road Redesign Tasks:
Task 1 - Revise Horizontal Alignment and Roadway Profile. Revise the Seippel
Road roadway horizontal alignment from approximately Sta. 51+00 Office Alignment
(OA) to approximately to Sta. 73+30 (OA), at the intersection of Ramps A and D
with Seippel Road/SW Arterial. Related work tasks include:
1) Redesign the roadway using the horizontal alignment labeled OA in the current
plans, and:
a. Develop the center left-turn lane width and right lane from
approximately Sta.51+00, east to the proposed intersection of the
proposed Landfill Access Road and Seippel Road.
b. Develop a transition from the three lane typical section to proposed
four-lane divided typical section at the intersection of Ramps A and D
with Seippel Road/SW Arterial.
2) Develop new superelevation transitions.
3) Redesign a new SW Arterial/Seippel Road profile.
a. The horizontal alignment and vertical profile, provided by the Iowa
DOT, for the Landfill Access Road will be included. It is anticipated
that WHKS will need to make an adjustment to the profile, based on
the redesign of Seippel Road. Lane requirements and storage lengths
used for design will be provided by the Iowa DOT.
Revise Sheets D.02-D.08 and include a new E Sheet for the Landfill Access Road.
Modify the G Sheets, as needed,for the Landfill Access Road and additional geometry
for controlling the variable width of the proposed revisions to Seippel Road. Update
H.1-H.3 to reflect roadway changes.
Task 2- Revise Typical Sections. Revise the typical sections for proposed urban and
rural three-lane section roadway. Four (4) new typical sections are anticipated for
Seippel Road. One (1) typical section for the Landfill Access Road will also be
developed, based on design information provided by Iowa DOT.
Task 3-Revise Ditching and Storm Sewer. Revise the rural ditch drainage design, as
appropriate. Revise the GEOPAK drainage model to perform the hydrologic and
eL=Com
Page 7
hydraulic modeling of the storm sewer system. Revise the design of the urban section
storm sewer drainage system, with an estimated 30 intakes and utility access
structures, along with the related storm sewer pipes between intakes and pipes that
outlet to ditches or drainageways. It is estimated that five (5) V' Sheets will be
required.
Task 4- Modify GEOPAK Model and Refine Cross Sections. The GEOPAK earthwork
(DTM) model will be modified for the revised horizontal and vertical designs and the
roadway cross section(s). New cross sections will be redeveloped for earthwork and
other quantities. The GEOPAK model will be in compliance with IDOT requirements
for the use of Corridor Modeler. Develop two (2) T Sheets to tabulate the soils
quantities. Modify the cross section sheets W.1-W.17.
Task 5- Intersection Design. Revise Sheets L.1-L.5 for the redesign of Seippel Road
at the intersection with Ramps A and D. Design the intersection of Seippel Road and
the Landfill Access Road and develop Sheets L.18-L.21 for geometric, edge profiles,
jointing and staking details.
Task 6- Shared-Use Path- Revise S Sheets. Revise the shared-use path alignment
and profile designs in compliance with current IDOT/PROWAG standards and the
revised design of Seippel Road. Design shared-path crossing of the proposed Landfill
Access Road, requiring two (2) handicapped ramps. Modify Sheets S.2 and S.3, and
provide new sheets documenting the shared-path handicapped ramp designs at the
Landfill Access Road.
Task 7 - Quantities and Cost Estimating
Task 8 - Quality Assurance/Quality Control
Task 9 - Project Administration/Project Management. Perform project
administration/project management, including coordination with the City of Dubuque,
the Iowa DOT and the Iowa DOT's consultant for the Landfill Access Road design.
Seippel Road Redesign Assumptions
1) The Seippel Road revised design will be included in the NHSX-032-1(44)--3H-
31 project, currently scheduled for the December 2018 letting.
2) GEOPAK Corridor Modeler will be used for the redesign.
3) Lighting design and lighting plan development will be provided by others.
4) Borrow design and sheets will not be required. Any borrow required will be
provided by the Contractor.
5) There will be no impact on existing ROW design parallel to Seippel Road, but
need lines for the intersection of the proposed Landfill Access Road will be
provided. It is assumed that WHKS will design the intersection with the
Landfill Access Road, but will stop construction at the end of the returns. ROW
design and other ROW tasks related to acquisition are not included in the
scope of work.
6) The relocated water main constructed under the NHSX-032-1(38)--3H-31
project will not be impacted by the redesign of Seippel Road.
7) The Landfill Access Road will be a stop controlled intersection, and no
provisions for traffic signals are in the Scope of Services.
8) No modifications to existing Q Sheets (soils) will be required.
eL=Com

Modification of Beam Type from PPCB to CWPG for SWA over US 61/151 and
Granger Creek
As a result of the aesthetic criteria and US 61/151 mainline and ramp geometry, an
Iowa DOT Standard Precast Prestressed Concrete Beam (PPCB) is not able to be
used at this crossing. This scope represents the additional effort to design and detail a
4-span Continuous Welded Plate Girder (CWPG) bridge, as detailed in the TSL
submitted to the Iowa DOT on December 15, 2016, beyond that of a PPCB bridge with
the following assumptions:
1) The abutments will have non-standard wing lengths, potentially supported on
counterforts.
2) All girders are designed and detailed the same.
3) Girder depth assumed in TSL will be sufficient.
4) Cross frames are IDOT typical X-frames.
5) Horizontal lateral bracing for wind is not required.
6) Erection stability of the girders will not be checked and erection
plans/calculations are not included.
7) MDX to be used for line girder design.
8) Bearings to be steel reinforced elastomeric pads with curved sole plates.
9) Joint assumed to be strip seals at each end.
10) Inspection cables/catwalk not included.
C. JCG Land Services
JCG Land Services requests a contingency release in the amount of$7,500.00(out of
$10,000.00 contingency) for the project. The majority of this contingency release
request is due to the extended negotiations and design revisions necessary for the
Tamorack Business Park.
II. TIME OF BEGINNING AND COMPLETION
The work shall be completed in accordance with the schedule defined in Supplemental
Agreement No. 15, which was extended to December 31, 2018.
III. COMPENSATION
The consultant shall be reimbursed for actual costs incurred in accordance with Article 3 of the
original agreement.
