This task includes the geometric design, cross sections, earthwork design, signing and incidental tasks for the turnaround. Task 3 - Modify or Add Additional Right -of -Way Documents. This task includes the preparation of additional or revised right-of-way plats, temporary and permanent easement plats, legal descriptions, plot plans and summary sheets for revised or new right-of-way parcels associated with the design changes. The additional hours added are a continuation of the original task and include the following parcels: • Parcel 129 (Haupert) — Supplementary Plat for Revised Culvert/Grading Design • Parcel 150B (Valentine) — Easements for Field Access Lane and BP Pipeline Relocation • Parcel 152 (Kress) — Revised Plats for Turnaround, for Purchase of Knepper Lane and for BP Pipeline Relocation • Parcel 161 (Reuter) — Revised Plat for Roadway Revisions and Easement for BP Pipeline Relocation • Parcel 187 (Luckstead) — Revised Plat for Connector Road "A" Revision • Parcel 195A (O'Rourke) — Revised Plat for U.S. 151/61 Interchange Revision • Three partial acquisition parcels for the Menards Frontage Road • Two Temporary Easement Parcels for the Menards Frontage Road Task 4 - Consultation for Condemnation Hearings. This task includes on-call consultation related to condemnation hearings and appeals during the right-of-way acquisition process. AECOM will provide materials, consultation and representation, as requested by the City. As the extent of this task is unknown, the task is limited to the estimated hours and costs provided in the staff -hour listing. Task 5 - Modify Environmental "White Paper". This task includes preparation of the modified environmental "white paper" to document revisions from the original Environmental Assessment (EA) and to incorporate the current concept for the Menards Frontage Road. This task includes determination of the associated impacts which need to be documented (such as farmland area, wetland area, forested area, etc.), and preparation of the "white paper" for submittal to DOT. It is anticipated that the level of detail required will be similar to the original "white paper" which was prepared earlier in the project. The additional hours added are a continuation of the original scope task item which will update the environmental "white paper" to reflect the current final design. Task 6 - Consultation for Utility Agreements. This task includes on-call consultation related to the negotiation of utility agreements for the project. It is anticipated that this will include the Black Hills Energy gas pipeline, the BP petroleum pipeline and the Century Link lines along U.S. 151/61. AECOM will provide materials, consultation and representation as requested by the City. As the extent of this task is unknown, the task is limited to the estimated hours and costs provided in the staff -hour listing. Task 7 - Additional Project Meetings and Coordination. This task includes the additional meetings, conference calls, web meetings and other coordination associated with the scope and schedule modifications in this supplemental agreement.

The Consultant will prepare display materials for the meeting, will assist in preparing the presentation, and will assist in conducting the meeting and preparing responses to citizen comments following the meeting. The City will arrange the meeting space, complete any advance advertising and mailings, and prepare and conduct the presentation. It is not anticipated that a formal transcript or meeting summary will be prepared. The additional hours added are a continuation of the original scope task item for Public Outreach/Informational Meetings. Task 10 - Update Labor and Overhead Rates. The original final design tasks for the SW Arterial were contracted on September 1, 2009, with an anticipated completion date of December 31, 2011. The original design contract was based on 2009 labor and overhead rates. The schedule for the project was subsequently revised, and a significant portion of the original design tasks have not yet been completed. Since 2009, AECOM's overhead rate has dropped from 165% to 147.56%, and labor rates have increased due to inflation. This task updates the labor and overhead rates for the original design contract hours which have not yet been expended. No new hours are added under this task. Task 11 - Property Acquisition Coordination with JCG Land. This task includes the coordination and exchange of information with JCG Land to accommodate their subcontract services for the acquisition of 28 right-of-way parcels. Activities included in this task are subcontract preparation and administration, processing of invoices, communications, exchange of files and information, and day-to-day coordination activities. B. WHKS Scope of Services Iowa DOT has determined that a frontage road will be designed, extending from south of the existing Menards entrance to a relocated intersection of Old Highway Road. The frontage road, labeled the "Northeast Access Connector Road" in the preliminary plans, will be on the east side of U.S. 20 and will be in general conformance with the U.S. 20 Location Study/EA Addendum, Refined Alternative B, 6 -Lane Alternative. This supplemental agreement will also include modifications to the design of several bridges throughout the corridor. The bridges' locations and the required design scope of work are described below. The scope of services is modified to include the following tasks, which were not included in the original scope or previous supplemental agreements. Task Group 1. SW Arterial Bridge Design Tasks: Task 1 — U.S. 20 WBL over Catfish Creek Bridge. Due to the new U.S. 20/SWA interchange layout changes, the SWA over U.S. 20 bridge width will be increased from the current layout. The length of the U.S. 20 WBL bridge over the South Fork of Catfish Creek will change, because of the IDOT decision to allow the use of a 3 -span PPCB H -standard bridge. The change will maintain the currently designed U.S. 20 AECOM Page 5 roadway profile grades, but will change the span lengths for this structure. The TS&L for the current configuration has been completed and approved by IDOT, design is complete and plans are approximately 75% complete. New tasks include: a) Revise Bridge Configuration/Geometry b) Prepare and Submit New TS&L c) Design and Prepare Plans for 40' Wide, 3 -Span PPCB H -Standard Bridge The impacts of the changes are significant, but WHKS has reviewed the staff hours used to date and it is estimated that the previously negotiated bridge staff hours will be adequate to complete the new tasks for a standard bridge without additional compensation. Task 2 — U.S. 20 EBL over Catfish Creek Bridge. Due to the new U.S. 20/SWA interchange layout changes, the SWA over U.S. 20 bridge width will be increased from the current layout. The length of the U.S. 20 EBL bridge over the South Fork of Catfish Creek will change, because of the IDOT decision to allow the use of a 3 -span PPCB H - standard bridge. The change will maintain the currently designed U.S. 20 roadway profile grades, but will change the span lengths for this structure. The TS&L for the current configuration has been completed and approved by IDOT, design is complete and plans are approximately 75% complete. New tasks include: a) Revise Bridge Configuration/Geometry b) Prepare and Submit New TS&L c) Design and Prepare Plans for 40' Wide, 3 -Span PPCB H -Standard Bridge The impacts of the changes are significant, but WHKS has reviewed the staff hours used to date and it is estimated that the previously negotiated bridge staff hours will be adequate to complete the new tasks for a standard bridge without additional compensation. Task 3 -.SWA over U.S. 20 and Catfish Creek Bridge. Due to the new U.S. 20/SWA interchange layout changes, this structure width will be increased from the current layout. The TS&L for the current configuration was in progress. New tasks include: a) Revise Bridge Configuration/Geometry b) Update in Progress TS&L Task 4 — U.S. 20 WB On -Ramp (Ramp D) Bridge. Due to the new U.S. 20/SWA interchange layout changes, this structure location and grade will be changed with the revised interchange layout. New tasks include: a) Revise Bridge Configuration/Geometry Task 5 — U.S. 20 EB On -Ramp (Ramp C) Bridge. Due to the new U.S. 20/SWA interchange layout changes, this structure grade will be changed with the SWA revised interchange layout and revisions to the 5 -legged roundabout. New tasks include: a) Revise Bridge Configuration/Geometry Task 6 - English Mill Road over SWA Bridge. The TS&L, design and final plans for this structure are complete. Final Plans were submitted in June 2011. New tasks include: a) Review and Modify Plans for Updated Standards AECOM Page 6 Task 7 - Military Road over SWA Bridge. The TS&L, design and final plans for this structure are complete. Final Plans were submitted in June 2011.

The TS&L for the current configuration has been completed, design is complete and plans are approximately 90% complete. New tasks include: a) Review and Modify Plans for Updated Standards Task 9 - South Fork Catfish Creek Hydraulics. Due to the new U.S. 20/SWA interchange layout changes, the current hydraulic analysis modeling will require modifications. Task Group 2. U.S. 20 Northeast Access Connector Road (aka Menards' Frontage Road) Design Tasks: The Northeast Access Connector Road will be designed in general conformance with the U.S. 20 Location Study/EA Addendum, Refined Alternative B, 6 -Lane Alternative. Supplemental Agreement No. 2 deleted the staff hours related to the Northeast Access Connector Road and the relocated connection of Old Highway Road, west of U.S. 20. Supplemental Agreement No. 14 restores the staff hours that were previously deleted in Supplemental Agreement No. 3, Tasks 26, 27 and 29. In addition, Supplemental Agreement No. 14 provides additional staff hours for the additional work caused by changes in the frontage road concept, the development of auxiliary lanes on U.S. 20 at the proposed relocated Old Highway Road intersection, and for the intersection traffic signal system design. Work on U.S. 20 related to the Northeast Access Connector Road will be limited to the full build -out of the Old Highway Road intersection to the ultimate configuration, tapering back to the existing roadway section as soon as possible. It is assumed that this work will produce construction plans that will be let independently of other SW Arterial construction packages. The plans will be prepared on 11"x17" sheets at a scale of 1"=200'. The following work tasks will be required: Task 1 — Restore Previously Negotiated Staff Hours Work to include: 1) The title and legend sheets (A -Series Sheets). 2) Typical cross sections and road design details (B -Series Sheets). 3) Bid Items and General Notes (C -Series Sheets) to include the following: a) Bid Item and Quantity Listing b) Estimate Reference Information c) General Notes 4) Tabulations and Quantities (C -Series Sheets).

Final bid quantities will be calculated and tabulated. 5) Plan and Profile Sheets (D-, E- and F -Series Sheets). This task consists of preparing the final plan and profile sheets for the project based on the previously completed design concept. ACO Page 7 6) Geometric Layout Sheets (G -Series Sheets). This task includes the geometric layout sheets, including centerline layouts and tabulations of geometric curve data and super elevation data. 7) Right -of -Way Layout Sheets (H -Series Sheets). Separate sheets will be included to show the new right-of-way and easement layouts for the project. 8) Staging and Traffic Control Design (J -Series Sheets). It is anticipated that the project will be constructed in stages to allow access to adjacent roads and properties to the extent practical. The scope for the construction staging plan is based on the following conditions: a) U.S. 20 will be kept open to 4 lanes of traffic. b) Other side roads may be temporarily closed during certain stages of the project. No on-site or marked detours are anticipated. 9) Intersection Details (L -Series Sheets). This task includes preparation of final intersection geometric layouts, including intersection radius design, spot elevations, and edge profiles for all paved intersections and cul-de-sacs. 10) Drainage and Culvert Design (M -Series Sheets). This task includes the final design of the drainage system and tabulation of crossroad pipe culvert drainage structures. The final drainage area maps and 1"=20' scale layouts for each culvert are included in this Scope. The following subtasks are included: a) Crossroad Pipe Culvert Design, Pink Sheets and Culvert Plats - Assume Six (6) Culverts b) Storm Sewer System Design (Estimated for 50 Intakes and 10 Utility Accesses), and "M" Sheets c) Tabulation of "Drainage Structures by Road Contractor" d) Tabulation of Storm Sewers 11) Soils Sheets (Q -Series Sheets). The soil profile base sheets (Q -Series Sheets) will be developed by WHKS and completed by Terracon Consultants. 12) Soils and Earthwork Design (T -Series Sheets). This task includes the final determination of earthwork quantities and design requirements, including cut and fill volumes. The geotechnical design for this project is being completed by Terracon Consultants. The tabulation of earthwork quantities is included in this task. 13) Detail Sheets (U -Series Sheets). The U -Series Sheets will be developed by WHKS. 14) Cross Section Sheets. Cross section sheets will be designed and developed for all affected roadways. Task 2 - Revisions to Frontage Road Concept. Previous staff hours were based on the utilization of an alignment and preliminary profile previously developed. Incorporating the new conceptual design provided by IDOT will require review and the development of the new horizontal and vertical alignments in compliance with the project design standards. New typical sections will also need to be developed. Task 3 - Traffic Signal Design (N -Series Sheets). The traffic signal system will be designed and the N -series sheets will be developed by WHKS. Task 4 - Additional Work Related to Adding Lanes to U.S. 20. With the goal of designing the relocated U.S. 20 intersection to the ultimate configuration, WHKS will design and develop plans for U.S. 20 for limits of construction to be established through coordination with IDOT and the City of Dubuque, using the IDOT PMT process. It is assumed that WHKS will prepare for, run and document the results of each meeting, design and detail the appropriate traffic control and staged construction details to maintain two lanes of traffic in each direction of U.S. 20, and maintain access to affected entrances and side roads. The design concept prepared by HDR for IDOT AECOM Page 8 will be used as the basis for the design, and required structural design of two (2) retaining walls. The TS&L and final design of the retaining walls is included in the scope of work. It is assumed the one wall will be approximately 380 feet long and will be designed as an MSE retaining wall. The second wall will be approximately 420 feet long and will be designed as a cast -in-place wall. Task 5 - Prepare Field Exam Plans. Prepare plans for, coordinate and attend a field exam meeting IDOT requirements, in order to confirm the design. Task 6 - Address Field Exam Comments. Based on the comments and directives obtained at the Field Exam, WHKS will document the Field Exam and incorporate the directives into the plans. Task 7 - Prepare ROW Field Exam Comments. Using the ROW and ownership information provided by AECOM, WHKS will establish the preliminary ROW need lines and proposed ROW, and depict the preliminary ROW in a set of plans suitable for a ROW field exam. Changes to the ROW will be documented and the plans will be revised per IDOT and City comments. The development of Plot Plans and Acquisition Plats will be by AECOM. Task Group 3. Additional Survey Tasks: The current WHKS survey budget has been utilized for previous design activities. Additional survey required for the new design tasks include: • U.S. 20 Interchange Area. Additional survey staff hours are requested to establish survey benchmarks and reference ties, so the plans can be in conformance with the IDOT "Office of Design Preliminary Survey Specifications", now that IDOT will let and construct the projects. U.S. 20 East Side Frontage Road to Menards. The topographic survey performed by WHKS will supplement the previous surveys and aerial mapping developed by the State. Note that the existing hard shots for U.S. 20 that are available from IDOT were taken in 1994, and are no longer considered valid. The topographic survey performed by WHKS will be in accordance with the IDOT "Office of Design Preliminary Survey Specifications". This work will include: ➢ Recover and verify horizontal and vertical control points established for SAP 0331 performed in 2004 as needed to establish additional control. ➢ Establish approximately 12 additional supplemental control points and bench marks along survey limits as needed. ➢ Topographic survey of edge of pavement along existing eastbound and westbound U.S. 20 approximately 5000 feet long including edge of pavement at five intersections and median crossovers. ➢ Topographic survey along the proposed frontage road approximately 4000 feet long. ➢ Topographic survey along Old Highway Road from the intersection of Radford Road to the intersection U.S. 20 approximately 900 feet long. ➢ Topographic survey of approximately six U.S. 20 drainage structures in the survey limits, if found. ➢ Initiate Iowa One -Call Design Request System for Quality Level C or D utility locations and shoot existing utilities. ➢ Office processing of Topographic and DTM shots.

Note that these fees would only be added for staff hours that have yet to be used for previously negotiated work tasks. Task 5. Additional effort to address IDOT and City of Dubuque requests since the project was put on hold in June 2012. Task 6. Additional staff hours to prepare, submit and coordinate with IDOT for the preliminary and final interchange submittals for the revised U.S. 20 interchange with the SW Arterial. Task 7. Additional staff hours to update cost estimates and quantities that have now changed due to the roadway modifications. AECOM Page 10 Task 8. Work task reductions due to the removal of the West Access Connector from the project: i) Roadway ii) Bridge Assumptions 1) The SWA will follow the office alignment as shown on the current G sheets. 2) The SWA Bridge over U.S. 20 will remain as 35 mph design speed. 3) The interchange ramp tapers will remain in the currently designed locations. 4) The 5 -legged roundabout will be revised, but will remain in the currently designed location, such that the geometry for the access road and Ramp B are unchanged. 5) GeoPak Corridor Modeler will be used for the re -design. 6) Lighting design and plan development will be provided by others. 7) Borrow design and sheets will not be required. Any borrow required will be provided by the Contractor. 8) U.S. 20 and the frontage roads at the intersection with Old Highway Road will be based on the design concept prepared for IDOT by HDR. 9) WHKS will prepare for, attend and run the PMT meetings for the U.S. 20/OId Highway Road area design development. Twelve (12) monthly meetings are assumed. C. Terracon Scope of Services The tasks for Terracon include additional work required for the added connector road at the U.S. 20 interchange. Task 1: Geotechnical Exploration and Design of the Menards Frontage Road The Menards Frontage Road will now be included in the Southwest Arterial project. Based on the provided aerial, we understand the frontage road will be about 4400 feet along. In addition, U.S. Highway 20 will be widened in both directions for a distance of about 2,500 feet. We understand two culverts (sizes unknown, but one will likely be an RCB) will be constructed. Two retaining walls are now included in the project. One wall is about 350 feet long and will have a maximum exposed wall height of about 7 feet. The other wall is about 325 feet long and will have a maximum exposed wall height of about 6 feet. We propose the following scope: Project Coordination and Field Services ■ Determination of proposed boring locations. ■ Design of sampling plan. ■ Contacting property owners. ■ Contacts for utility locations. ■ Supervision of drilling operations. ■ 48 borings to average depths of 30 feet (including about 130 feet of rock core) ■ 30 borings to average depths of 15 feet. ■ 4 pavement cores on existing U.S. Highway 20. Laboratory Testing ■ Test assignments. AECO Page 11 • 5 unconsolidated, undrained triaxial shear tests. • 3 consolidated, undrained triaxial shear tests • 5 consolidation tests. • 40 Atterberg limits and grain size analyses. • 75 dry density and moisture content tests. • 15 unconfined compressive strength tests on soils. • 30 moisture -density (one -point Proctor) tests. • 1 organic content test (loss on ignition) • Supervision of laboratory testing. • Engineering review of laboratory test results. Engineering and CADD Services • Computer generated boring logs for RCB culvert borings and retaining walls. • Stability analyses for the large road fill area and deep road cut areas (4 locations). • Stability, settlement, and bearing capacity analyses for the retaining walls (2 locations). • Settlement estimates for the culverts (2 locations) • Supplement Report of Soundings for RCB culvert borings. • Remedial soils design to address stability problems at 1 location using typical remedial designs such as flattening the backslope or adding a berm at the toe of the foreslope. • Symbolized results of the drilling and testing in Iowa DOT format added to digital drawings to create Q sheets for the frontage road, U.S. Highway 20, retaining walls, and Soil Profile Sheet for RCB culvert (total of 8 sheets). • Subsurface layer (TIN) files for soils encountered in cut areas. • 3 conference calls with stakeholders • Contract administration Other Conditions Our reports will be sealed by an Iowa Licensed Professional Engineer. The conditions for our work will remain the same as in previous supplemental agreements for this project. We anticipate staking the borings using a hand held GPS with sub -meter accuracy. Based on the proposed boring locations, we anticipate traffic control and right-of-way permits will be required. We understand that the schedule for this project has not been determined. To assure that we can meet the requested schedule, the schedules will be negotiated with all parties when further information is available. D. Vern Schaefer Scope of Services Task 1 - Eliminate Remaining Scope. Dr. Vern Schaefer was originally contracted for "on-call" services to assist Terracon with analysis and testing related to the Maquoketa shale on the project. Dr. Schaefer completed the requested on-call services during the time when the shale was being analyzed for design alternatives. This work has been completed, and Terracon does not anticipate any future consultations with Dr. Schaefer. This task eliminates the remaining unused portion of the budget for Dr. Schaefer. AECOM Page 12 E. RDG Planning and Design Scope of Services The revised tasks for RDG consist of modifications to the previous scope and revisions to previously -completed work, as well as new tasks related to the current enhancement concept design for the project. All of the final design of roadside enhancements is deleted by this revision, including roadside landscaping, trailhead development, kiosks, site furnishings, rest facilities, special signing and other amenities. Further evaluation and design of sustainable design features (other than standard features which are typically used on Iowa primary road projects) is deleted by this revision. RDG's revised scope will be limited to the bridge enhancements for the three SW Arterial bridges over U.S. 20, Catfish Creek and U.S. 151/61. It is anticipated that the bridge enhancement concepts will remain the same as the currently -approved concepts, and that no additional concept analysis and development will be needed for the bridges. RDG's scope is further described as follows. Task 1. Delete Portions of Existing Scope. RDG has already completed portions of the existing scope related to the concept development and design development for sustainable design features, conceptual design for the roadside enhancement features, and concept development and partial design for the bridge enhancements. This task will delete portions of the remaining hours and budgets for selected tasks from the original agreement and previous supplemental agreements.

Additional Bridge Enhancement Design. This task includes the preliminary and final lighting design for the three enhanced bridges over U.S. 20, Catfish Creek, and U.S. 151/61. The lighting design will include roadway, accent and pedestrian -level lighting in accordance with the currently -approved conceptual design for these bridges. The following subtasks are included: 1. Electrical engineering, including final plans and specifications for the electrical control station, conduits and wiring to provide an operational lighting system at each of the three enhanced bridges. 2. Lighting design, including the determination of light poles, fixtures, spacing and placements, and preparation of final plans and specifications to provide an operational lighting system at each of the three enhanced bridges. F. Durrant Scope of Services Durrant's remaining scope of services was transferred to RDG under the previous Supplemental Agreement No. 11, and Durrant's remaining budget was intended to be eliminated. Upon receipt of Durrant's final invoice, it was determined that the cost reduction in Supplemental Agreement No. 11 resulted in a remaining balance of $382.05 in their contract. The current Supplemental Agreement will deduct this amount from the project budget. G. Design Standards The Consultant will monitor and review updates to the State's Highway Division Road Design Manual, Standard Road Plans and Road Design Details. Updates requiring no additional effort on the part of the Consultant will be incorporated into the work by the Consultant. If the Consultant is of the opinion additional effort will be required, the Consultant will so notify the Contract Administrator in accordance with Paragraph 4.3.1 The Contract Administrator will provide written approval or disapproval for the Consultant to incorporate said update into the work and indicate how payment for such work will be addressed. Services provided by the Consultant shall be in conformity with the Standard Practices and Requirements as shown in Attachment B. A COM II. TIME OF BEGINNING AND COMPLETION Page 14 Work under this Supplemental Agreement No. 14 is authorized to begin upon receipt of written Notice to Proceed. The work shall be completed in accordance with the schedule defined in Supplemental Agreement No. 11, which is extended from June 30, 2014, to December 31, 2015. The project development schedule for the Menard's Frontage Road/U.S. 20 Project will be compressed in anticipation of a June 16, 2015, letting. However, there are a number of factors that are beyond the control of the design team, including the Notice to Proceed date, complexity of the design, coordination with the parties involved in the various submittals, reviews and PMT meeting dates, unknown final geotechnical design factors, environmental clearances, right-of- way acquisition, in addition to other unknowns. The design team will work with the City and IDOT to develop a mutually acceptable schedule of IDOT event codes, compressed to meet a June 16, 2015, letting. However, itis not possible for the design team to be responsible for the completion of work tasks/events by others. III.

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. In November 2012, the Iowa Department of Transportation changed the design of the project. The decision by the Iowa Department of Transportation to change the interchange design negates approximately 24 months of preliminary and final engineering design development for the two interchange areas, and will require significant plan changes. This will also require the design team to take a step back in the design process and again re-initiate the preliminary design phase to evaluate the interchange types and configurations. Assistant City Engineer Bob Schiesl recommends City Council authorization for the Mayor to execute the Consultant Professional Services — 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.

Van Milligen, City Manager Gus Psihoyos, City Engineer Robert Schiesl, Assistant City Engineer Southwest Arterial Project Consultant Professional Services - Supplemental Agreement Final Engineering Design Phase - Scope of Work Modifications Iowa DOT Project No. STP -U-2100 (634)--70-31 DATE: August 26, 2014 INTRODUCTION Dubuque bitetri All -America City 1 r 2007 • 2012 • 2013 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. BACKGROUND 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. In November, 2012 the Iowa DOT changed the design of the project. Following the November announcement, the City continued the position that all major design team efforts remain temporarily on -hold while the City and the Iowa DOT further refined and clarified the proposed changes, define the design parameters moving forward and evaluate the changes to the final engineering design scope of services. The decision by the IDOT to change the interchange design negates approximately 24 months of preliminary and final engineering design development for the two interchange areas, and will require significant plan changes. This will also require the design team to take a step back in the design process and again re-initiate the preliminary design phase to evaluate the interchange types and configurations. The preliminary re -design efforts for the interchanges will be quite extensive. The re- design efforts will require the design team to: evaluate new interchange layouts; perform detailed traffic analysis; develop new signalized intersection details; investigate design variations for the bridges; coordinate reviews with Iowa DOT staff; evaluate potential impacts to right-of-way acquisition at the interchange locations; evaluate potential impacts to wetlands; historic and cultural resource areas; review watershed and stream crossing impacts, and environmental clearance compliance. December 2013 to June 2014 - the design team has been evaluating the level of re- design efforts required so that a supplemental agreement to the existing design contract can be developed for the continued development and advancement of the Southwest Arterial project. 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. The Consultant Professional Services - Supplemental Agreement authorizes AECOM to provide the revised scope of services in accordance with Iowa DOT and FHWA procedures and requirements. As a result of the proposed design and plan modifications, the original scope of services needs to be revised to reflect the following task modifications to previously -completed design elements, as well as new tasks which are considered "critical path schedule items" that are required to continue to advance the completion of the final engineering design phase: • U.S. 20 Interchange: Revisions to the preliminary design plans to eliminate the roundabout intersection at the westbound ramp terminal, redesign the ramp with a conventional signalized intersection. • U.S. 20 Interchange: Revisions to the preliminary design plans to incorporate a 5 -leg roundabout intersections at the eastbound ramp terminal. • U.S. 20 Interchange: The new interchange layout will require the interchange bridge over U.S. 20 to change from the previous 3 -lane bridge to a wider 4 -lane structure. • U.S. 20 Interchange: The new interchange layout will require the current hydraulic analysis modeling to be updated. • U.S. 61/151 Interchange: Revisions to the preliminary construction plans to eliminate the roundabout intersections and redesign the ramp terminals with conventional signalized intersections. • Right -of -Way Documents: preparation of additional or revised right-of-way plats, temporary and permanent easement plats, legal descriptions, plot plans and summary sheets for revised or new right-of-way parcels associated with the design changes. • NEPA Re -Evaluation: Due to the project design changes / revisions that occurred since 2010, a public informational meeting was conducted and a summary report prepared and submitted to FHWA for review and approval. With the Iowa DOT's recent completion of the U.S. 20 Location Study, and the final selection of the preferred 6 -Lane Alternative B, this provided guidance and direction on future capacity improvements along U.S. 20 between Old Highway Road and Cresent Ridge intersections. The future capacity improvements include the reconstruction of the Old Highway Road intersection; adding additional turn lanes and mainline widening of U.S. 20; the closure of the existing Menards at -grade intersection and the construction of the new frontage road along the south side of U.S. 20, extending from the Old Highway Road intersection to Menards. Due to the location of the existing Menards at -grade intersection and the location of the Southwest Arterial - U.S. 20 interchange, spacing and access control requirements mandate that the Menards at -grade intersection be closed prior to opening the Southwest Arterial - U.S. 20 interchange. As a result, the "Menards Frontage Road" and related improvements are being added to the final engineering design phase of the Southwest Arterial project, and will include the following tasks: • Menards Frontage Road Design • Old Highway Road Intersection Design • U.S. 20 Mainline Widening and Turn Lanes • Drainage, Storm Sewer and Culvert Design • Right -of -Way Property Acquisition Layout • Staging and Traffic Control Design • Traffic Signal Design • Geotechnical Investigation The design team is currently evaluating the level of effort required for modifications to previously -completed design elements, as well as new tasks which are required for the "grade four lanes/pave two lanes" project in addition to the "pave remaining two lanes" project so that a future Supplemental Agreement No. 15 can be developed to continue to advance the completion of the final engineering design phase in accordance with and subject to the approval of both the Iowa DOT and FHWA. RECOMMENDATION I recommend that the City Council authorize the Mayor to execute the Consultant Professional Services - 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. BUDGET IMPACT The estimated professional services fee for the proposed design and plan modifications to the original scope of services for the final design phase of the Southwest Arterial project is as follows: The project funding summary is as follows: CIP Descri 'tion Amount 3001287 Supplemental Agreement No. 14 - Scope of Services Revisions $ 653,850 3001287 Total Project Cost $ 653,850 The project funding summary is as follows: CIP Funding Source Amount 3001287 Federal SAFETEA-LU Funding (80%) $ 523,080 3001287 Local Funding (20%) 130,770 Total Project Funding 653 850 ACTION TO BE TAKEN The City Council is requested to authorize the Mayor to execute the Consultant Professional Services - Supplemental Agreement with AECOM Technical Services, Inc. to include the completion of right-of-way property acquisition for the Southwest Arterial Project, subject to the concurrence of the Iowa Department of Transportation through adoption of the enclosed resolution.

The schedule for the project was subsequently revised, and a significant portion of the original design tasks have not yet been completed. Since 2009, AECOM's overhead rate has dropped from 165% to 147.56%, and labor rates have increased due to inflation. This task updates the labor and overhead rates for the original design contract hours which have not yet been expended. No new hours are added under this task. Task 11 - Property Acquisition Coordination with JCG Land. This task includes the coordination and exchange of information with JCG Land to accommodate their subcontract services for the acquisition of 28 right-of-way parcels. Activities included in this task are subcontract preparation and administration, processing of invoices, communications, exchange of files and information, and day-to-day coordination activities. B. WH KS Scope of Services Iowa DOT has determined that a frontage road will be designed, extending from south of the existing Menards entrance to a relocated intersection of Old Highway Road. The frontage road, labeled the "Northeast Access Connector Road" in the preliminary plans, will be on the east side of US 20 and will be in general conformance with the US 20 Location Study/EA Addendum, Refined Alternative B, 6 -Lane Alternative. This supplemental agreement will also include modifications to the design of several bridges throughout the corridor. The bridges' locations and the required design scope of work are described below. The scope of services is modified to include the following tasks, which were not included in the original scope or previous supplemental agreements. Task Group 1. SW Arterial Bridge Design Tasks: Task 1 - US 20 WBL over Catfish Creek Bridge. Due to the new US 20/SWA interchange layout changes, the SWA over US 20 bridge width will be increased from the current layout. The length of the US 20 WBL bridge over the South Fork of Catfish Creek will change, because of the IDOT decision to allow the use of a 3 -span PPCB H - standard bridge. The change will maintain the currently designed US 20 roadway profile grades, but will change the span lengths for this structure. The TS&L for the current configuration has been completed and approved by IDOT, design is complete and plans are approximately 75% complete. New tasks include: a) Revise Bridge Configuration/Geometry b) Prepare and Submit New TS&L A=COM Page 5 c) Design and Prepare Plans for 40' Wide, 3 -Span PPCB H -Standard Bridge The impacts of the changes are significant, but WHKS has reviewed the staff hours used to date and it is estimated that the previously negotiated bridge staff hours will be adequate to complete the new tasks for a standard bridge without additional compensation. Task 2 - US 20 EBL over Catfish Creek Bridge. Due to the new US 20/SWA interchange layout changes, the SWA over US 20 bridge width will be increased from the current layout. The length of the US 20 EBL bridge over the South Fork of Catfish Creek will change, because of the IDOT decision to allow the use of a 3 -span PPCB H - standard bridge. The change will maintain the currently designed US 20 roadway profile grades, but will change the span lengths for this structure. The TS&L for the current configuration has been completed and approved by IDOT, design is complete and plans are approximately 75% complete. New tasks include: a) Revise Bridge Configuration/Geometry b) Prepare and Submit New TS&L c) Design and Prepare Plans for 40' Wide, 3 -Span PPCB H -Standard Bridge The impacts of the changes are significant, but WHKS has reviewed the staff hours used to date and it is estimated that the previously negotiated bridge staff hours will be adequate to complete the new tasks for a standard bridge without additional compensation. Task 3 - SWA over US 20 and Catfish Creek Bridge. Due to the new US 20/SWA interchange layout changes, this structure width will be increased from the current layout. The TS&L for the current configuration was in progress. New tasks include: a) Revise Bridge Configuration/Geometry b) Update in Progress TS&L Task 4 - US 20 WB On -Ramp (Ramp D) Bridge. Due to the new US 20/SWA interchange layout changes, this structure location and grade will be changed with the revised interchange layout. New tasks include: a) Revise Bridge Configuration/Geometry Task 5 - US 20 EB On -Ramp (Ramp C) Bridge. Due to the new US 20/SWA interchange layout changes, this structure grade will be changed with the SWA revised interchange layout and revisions to the 5 -legged roundabout. New tasks include: a) Revise Bridge Configuration/Geometry Task 6 - English Mill Road over SWA Bridge. The TS&L, design and final plans for this structure are complete. Final Plans were submitted in June 2011. New tasks include: a) Review and Modify Plans for Updated Standards Task 7 - Military Road over SWA Bridge.

The TS&L for the current configuration has been completed, design is complete and plans are approximately 90% complete. New tasks include: a) Review and Modify Plans for Updated Standards Task 9 - South Fork Catfish Creek Hydraulics. Due to the new US 20/SWA interchange layout changes, the current hydraulic analysis modeling will require m odifications. Task Group 2. US 20 Northeast Access Connector Road (aka Menards' Frontage Road) Design Tasks: The Northeast Access Connector Road will be designed in general conformance with the US 20 Location Study/EA Addendum, Refined Alternative B, 6 -Lane Alternative. Supplemental Agreement No. 2 deleted the staff hours related to the Northeast Access Connector Road and the relocated connection of Old Highway Road, west of US 20. Supplemental Agreement No. 8 restores the staff hours that were previously deleted in Supplemental Agreement No. 2, Tasks 26, 27 and 29. In addition, Supplemental Agreement No. 8 provides additional staff hours for the additional work caused by changes in the frontage road concept, the development of auxiliary lanes on US 20 at the proposed relocated Old Highway Road intersection, and for the intersection traffic signal system design. Work on US 20 related to the Northeast Access Connector Road will be limited to the full build -out of the Old Highway Road intersection to the ultimate configuration, tapering back to the existing roadway section as soon as possible. It is assumed that this work will produce construction plans that will be let independently of other SW Arterial construction packages. The plans will be prepared on 11'x17" sheets at a scale of 1"=200'. The following work tasks will be required: Task 1 — Restore Previously Negotiated Staff Hours Work to include: 1) The title and legend sheets (A -Series Sheets). 2) Typical cross sections and road design details (B -Series Sheets). 3) Bid Items and General Notes (C -Series Sheets) to include the following: a) Bid Item and Quantity Listing b) Estimate Reference Information c) General Notes 4) Tabulations and Quantities (C -Series Sheets). Detailed tabulations will be included for most bid items in accordance with Iowa DOT standards. This task includes the roadway grading tabulations which are not included elsewhere in the scope. Final bid quantities will be calculated and tabulated. 5) Plan and Profile Sheets (D-, E- and F -Series Sheets). This task consists of preparing the final plan and profile sheets for the project based on the previously completed design concept. 6) Geometric Layout Sheets (G -Series Sheets). This task includes the geometric layout sheets, including centerline layouts and tabulations of geometric curve data and super elevation data. 7) Right -of -Way Layout Sheets (H -Series Sheets). Separate sheets will be included to show the new right-of-way and easement layouts for the project. 8) Staging and Traffic Control Design (J -Series Sheets). It is anticipated that the project will be constructed in stages to allow access to adjacent roads and A=COM Page 7 properties to the extent practical. The scope for the construction staging plan is based on the following conditions: a) U.S. 20 will be kept open to 4 lanes of traffic. b) Other side roads may be temporarily closed during certain stages of the project. No on-site or marked detours are anticipated. 9) Intersection Details (L -Series Sheets). This task includes preparation of final intersection geometric layouts, including intersection radius design, spot elevations, and edge profiles for all paved intersections and cul-de-sacs. 10) Drainage and Culvert Design (M -Series Sheets). This task includes the final design of the drainage system and tabulation of crossroad pipe culvert drainage structures. The final drainage area maps and 1"=20' scale layouts for each culvert are included in this Scope. The following subtasks are included: a) Crossroad Pipe Culvert Design, Pink Sheets and Culvert Plats - Assume Six (6) Culverts b) Storm Sewer System Design (Estimated for 50 Intakes and 10 Utility Accesses), and "M" Sheets c) Tabulation of "Drainage Structures by Road Contractor" d) Tabulation of Storm Sewers 11) Soils Sheets (Q -Series Sheets). The soil profile base sheets (Q -Series Sheets) will be developed by WHKS and completed by Terracon Consultants. 12) Soils and Earthwork Design (T -Series Sheets). This task includes the final determination of earthwork quantities and design requirements, including cut and fill volumes. The geotechnical design for this project is being completed by Terracon Consultants. The tabulation of earthwork quantities is included in this task. 13) Detail Sheets (U -Series Sheets). The U -Series Sheets will be developed by WHKS. 14) Cross Section Sheets. Cross section sheets will be designed and developed for all affected roadways. Task 2 - Revisions to Frontage Road Concept. Previous staff hours were based on the utilization of an alignment and preliminary profile previously developed. Incorporating the new conceptual design provided by IDOT will require review and the development of the new horizontal and vertical alignments in compliance with the project design standards. New typical sections will also need to be developed. Task 3 - Traffic Signal Design (N -Series Sheets). The traffic signal system will be designed and the N -series sheets will be developed by WHKS. Task 4 - Additional Work Related to Adding Lanes to US 20. With the goal of designing the relocated US 20 intersection to the ultimate configuration, WHKS will design and develop plans for US 20 for limits of construction to be established through coordination with IDOT. Design and detail the appropriate traffic control and staged construction details to maintain 2 lanes of traffic in each direction on US 20, and maintain access to affected entrances and side roads. Task 5 - Prepare Field Exam Plans. Prepare plans for, coordinate and attend a field exam meeting IDOT requirements, in order to confirm the design. Task 6 - Address Field Exam Comments. Based on the comments and directives obtained at the Field Exam, WHKS will document the Field Exam and incorporate the directives into the plans. A=COM Page 8 Task 7 - Prepare ROW Field Exam Comments. Using the ROW and ownership information provided byAECOM, WHKS will establish the preliminary ROW need lines and proposed ROW, and depict the preliminary ROW in a set of plans suitable for a ROW field exam. Changes to the ROW will be documented and the plans will be revised per IDOT and City comments. The development of Plot Plans and Acquisition Plats will be by AECOM. Task Group 3. Additional Survey Tasks: The current WHKS survey budget has been utilized for previous design activities. Additional survey required for the new design tasks include: • US 20 Interchange Area. Additional survey staff hours are requested to establish survey benchmarks and reference ties, so the plans can be in conformance with the IDOT "Office of Design Preliminary Survey Specifications", now that IDOT will let and construct the projects. • US 20 East Side Frontage Road to Menards. The topographic survey performed by WH KS will supplement the previous surveys and aerial mapping developed by the State. Note that the existing hard shots for US 20 that are available from IDOT were taken in 1994, and are no longer considered valid. The topographic survey performed by WHKS will be in accordance with the IDOT "Office of Design Preliminary Survey Specifications". This work will include: • Recover and verify horizontal and vertical control points established for SAP 0331 performed in 2004 as needed to establish additional control. D Establish approximately 12 additional supplemental control points and bench marks along survey limits as needed. D Topographic survey of edge of pavement along existing eastbound and westbound US 20 approximately 5000 feet long including edge of pavement at five intersections and median crossovers. D Topographic survey along the proposed frontage road approximately 4000 feet long. D Topographic survey along Old Highway Road from the intersection of Radford Road to the intersection US 20 approximately 900 feet long. • Topographic survey of approximately six US 20 drainage structures in the survey limits, if found. • Initiate Iowa One -Call Design Request System for Quality Level C or D utility locations and shoot existing utilities. • Office processing of Topographic and DTM shots. The work tasks included in the additional survey task group include: Task 1. Administration, coordination and meetings related to the additional survey. Task 2. Recover existing control points.

Note that these fees would only be added for staff hours that have yet to be used for previously negotiated work tasks. Task 5. Additional effort to address IDOT and City of Dubuque requests since the project was put on hold in June 2012. Task 6. Additional staff hours to prepare, submit and coordinate with IDOT for the preliminary and final interchange submittals for the revised US 20 interchange with the SW Arterial. Task 7. Additional staff hours to update cost estimates and quantities that have now changed due to the roadway modifications. Task 8. Work task reductions due to the removal of the West Access Connector from the project: i) Roadway ii) Bridge Assumptions 1) The SWA will follow the office alignment as shown on the current G sheets. 2) The SWA Bridge over US 20 will remain as 35 mph design speed. 3) The interchange ramp tapers will remain in the currently designed locations. A=COM Page 10 4) The 5 -legged roundabout will be revised, but will remain in the currently designed location, such that the geometry for the access road and Ramp B are unchanged. 5) GeoPak Corridor Modeler will be used for the re -design. 6) Lighting design and plan development will be provided by others. 7) Borrow design and sheets will not be required. Any borrow required will be provided by the Contractor. 8) US 20 and the frontage roads at the intersection with Old Highway Road will be based on the design concept prepared for IDOT by HDR. 9) WHKS will prepare for, attend and run the PMT meetings for the US 201OId Highway Road area design development. Twelve (12) monthly meetings are assumed. C. Terracon Scope of Services The tasks for Terracon include additional work required for the added connector road at the US 20 interchange. Task 1: Geotechnical Exploration and Design of the Menards Frontage Road The Menards Frontage Road will now be included in the Southwest Arterial project. Based on the provided aerial, we understand the frontage road will be about 4400 feet along. In addition, U.S. Highway 20 will be widened in both directions for a distance of about 2,500 feet. We understand two culverts (sizes unknown, but one will likely be an RCB) will be constructed. Two retaining walls are now included in the project. One wall is about 350 feet long and will have a maximum exposed wall height of about 7 feet. The other wall is about 325 feet long and will have a maximum exposed wall height of about 6 feet. We propose the following scope: Project Coordination and Field Services ■ Determination of proposed boring locations. ■ Design of sampling plan. ■ Contacting property owners. ■ Contacts for utility locations. ■ Supervision of drilling operations. ■ 48 borings to average depths of 30 feet (including about 130 feet of rock core) ■ 30 borings to average depths of 15 feet. ■ 4 pavement cores on existing US Highway 20. Laboratory Testing ■ Test assignments. ■ 5 unconsolidated, undrained triaxial shear tests. ■ 3 consolidated, undrained triaxial shear tests • 5 consolidation tests. • 40 Atterberg limits and grain size analyses. • 75 dry density and moisture content tests. ■ 15 unconfined compressive strength tests on soils. ■ 30 moisture -density (one -point Proctor) tests. ■ 1 organic content test (loss on ignition) ■ Supervision of laboratory testing. A=COM ■ Engineering review of laboratory test results. Page 11 Engineering and CADD Services ■ Computer generated boring logs for RCB culvert borings and retaining walls. ■ Stability analyses for the large road fill area and deep road cut areas (4 locations). ■ Stability, settlement, and bearing capacity analyses for the retaining walls (2 locations). ■ Settlement estimates for the culverts (2 locations) ■ Supplement Report of Soundings for RCB culvert borings. ■ Remedial soils design to address stability problems at 1 location using typical remedial designs such as flattening the backslope or adding a berm at the toe of the foreslope. • Symbolized results of the drilling and testing in Iowa DOT format added to digital drawings to create Q sheets for the frontage road, U.S. Highway 20, retaining walls, and Soil Profile Sheet for RCB culvert (total of 8 sheets). • Subsurface layer (TIN) files for soils encountered in cut areas. ■ 3 conference calls with stakeholders ■ Contract administration Other Conditions Our reports will be sealed by an Iowa Licensed Professional Engineer. The conditions for our work will remain the same as in previous supplemental agreements for this project. We anticipate staking the borings using a hand held GPS with sub -meter accuracy. Based on the proposed boring locations, we anticipate traffic control and right-of-way permits will be required. We understand that the schedule for this project has not been determined. To assure that we can meet the requested schedule, the schedules will be negotiated with all parties when further information is available. D. Vern Schaefer Scope of Services Task 1- Eliminate Remaining Scope. Dr. Vern Schaefer was originally contracted for "on-call" services to assist Terracon with analysis and testing related to the Maquoketa shale on the project. Dr. Schaefer completed the requested on-call services during the time when the shale was being analyzed for design alternatives. This work has been completed, and Terracon does not anticipate any future consultations with Dr. Schaefer. This task eliminates the remaining unused portion of the budget for Dr. Schaefer. E. RDG Planning and Design Scope of Services The revised tasks for RDG consist of m odifications to the previous scope and revisions to previously -completed work, as well as newtasks related to the current enhancement concept design for the project. All of the final design of roadside enhancements is deleted by this revision, including roadside landscaping, trailhead development, kiosks, site furnishings, rest facilities, special signing and other amenities. Further evaluation and design of sustainable design features (other than standard features which are typically used on Iowa primary road projects) is deleted by this revision. RDG's revised scope will be limited to the bridge enhancements for the three SW Arterial bridges over US 20, Catfish Creek and US 151/61. It is anticipated that the bridge enhancement A=COM Page 12 concepts will remain the same as the currently -approved concepts, and that no additional concept analysis and development will be needed for the bridges. RDG's scope is further described as follows. Task 1. Delete Portions of Existing Scope. RDG has already completed portions of the existing scope related to the concept development and design development for sustainable design features, conceptual design for the roadside enhancement features, and concept development and partial design for the bridge enhancements. This task will delete portions of the remaining hours and budgets for selected tasks from the original agreement and previous supplemental agreements. Other partially -completed tasks will remain in the scope. The scope modifications include deleting the unfinished portions of the following tasks: 1.

Additional Bridge Enhancement Design. This task includes the preliminary and final lighting design for the three enhanced bridges over US 20, Catfish Creek, and US 151/61. The lighting design will include roadway, accent and pedestrian -level lighting in accordance with the currently -approved conceptual design for these bridges. The following subtasks are included: 1. Electrical engineering, including final plans and specifications for the electrical control station, conduits and wiring to provide an operational lighting system at each of the three enhanced bridges. 2. Lighting design, including the determination of light poles, fixtures, spacing and placements, and preparation of final plans and specifications to provide an operational lighting system at each of the three enhanced bridges. F. Durrant Scope of Services Durrant's remaining scope of services was transferred to RDG under the previous Supplemental Agreement No. 11, and Durrant's remaining budget was intended to be eliminated. Upon receipt of Durrant's final invoice, it was determined that the cost reduction in Supplemental Agreement No. 11 resulted in a remaining balance of $382.05 in their contract. The current Supplemental Agreement will deduct this amount from the project budget. II.
