The Consultant will lead the project and work in coordination with subconsultants, LDC, Inc, to provide a consistent overall project design across engineering disciplines. The scope of work includes an alternatives analysis and design tasks up to the delivery of 100% bid-ready plans, specifications and estimate. Work Program The Consultant work program is organized into the following tasks: Task 1. Project Management Task 2. Alternatives Analysis & Conceptual (10%) Project Design Task 3. 50%, 90% and 100% Design Plans, Specifications, and Estimates (PS&E) Task 4. Project Support Task 5. Bid and Award Support Project Definition The Consultant has developed this scope with the assumption of the following key project components. Key components are identified based on the City's grant funding applications and STIP description for project REN-48. Oakesdale Avenue SW -Overlay & Rechannelization Project Limits: Oakesdale Avenue SW from the south side of the intersection with SW 34th Street to the north side of the intersection with SW 16th Street. Approximately 6,100 linear feet. Includes ADA-required modification of curb ramps (due to federal project funding) at the intersections with SW 34th Street, SW 27th Street, SW 20th Street, and SW 16th Street, and rebuilding of commercial driveways with curb ramps. Project Elements: Overlay the existing pavement (2" plane and overlay). Restripe and provide other surface-mounted/surface-level elements (i.e. no new curb & gutter) to enhance or add to existing on-road bike facilities and calm traffic. Raised intersections may be considered. Design Standards Reports, design documentation, plans and specifications, to the extent feasible, will be developed in accordance with the following, as applicable: 1.Washington State Department of Transportation/American Public Works Association, "Standard Specifications for Road, Bridge, and Municipal Construction", M41-10, Current Electronic Version. 2.Washington State Department of Transportation, "Standard Plans for Road and Bridge Construction", M21-01, Current Electronic Version. 3.Washington State Department of Transportation, "Design Manual", M22-01, Current Electronic Version. 4.FHWA and Washington State Department of Transportation, "Manual on Uniform Traffic Control Devices for Streets and Highways" 2009 or current version adopted by the State of Washington, 5.A Policy on Geometric Design of Highways and Streets (MSHTO green book), 7th Edition, 2018. 6.NACTO Urban Street Design Guide and Urban Bikeway Design Guide, current versions 7.City of Renton Standard Plans -Current Versions 8.Applicable provisions of the Americans with Disabilities Act, as amended; and other applicable local, State and Federal standards as required. a.PROWAG 2005, as modified by the City of Renton Assumptions The Consultant has developed this scope with the assumption that the project elements identified in the City's grant application and STIP entry (REN-48) and described herein are the basis of design. Modifications to project elements described in this scope, may require a negotiated fee and schedule modification between the Consultant and the City. The Consultant will make a good faith effort to accommodate reasonable requests to modify the scope during the design process and will notify the City as soon as possible of the anticipated impact of significant changes to project elements on fee and schedule. This Scope of Services assumes the following: •Right of way acquisition is not desirable, but may be required to construct required curb ramps. •The Consultant will provide drawings, estimated right of way needs, and legal descriptions, but will not conduct the right of way acquisition process. The City will conduct right of way acquisition separately. •No franchise or local utility relocations, including water or sewer lines, are anticipated, or included in the scope of work. •No stormwater system modifications are anticipated or included in the current scope of work. If a raised intersection or crosswalk is added, stormwater modifications will be required. If stormwater modifications are required, an amended scope and fee will be prepared and agreed to by the City and the Consultant. •The Consultant will support the required NEPA permitting, but the development of the NEPA permit application and coordination with WSDOT will occur under a separate contract between the City of Renton and another consultant. •No public outreach is anticipated, or included in the scope of work. This does not preclude the preparation of some engineering drawings or concepts as exhibits for presentation at council meetings or public outreach conducted by the City project manager. •The Consultant shall prepare the special provisions and applicable amendments to the contract provisions, Divisions two through nine, as required for the improvements. The Consultant will prepare special provisions for those items not covered by the standard specifications, general special provisions or amendments. •The Consultant will prepare the Division one specifications and upfront Bid Documents with information dependent on the City's schedule and preferences. The Consultant will compile the final specifications document for bid. The contract provisions shall be prepared in accordance with the requirements of WSDOT and the City of Renton. The Consultant will coordinate with WSDOT to finalize acceptance of the Division 1 specifications and construction obligation. a.The City will provide the required information and signatures to complete the Local Agency Agreement (LAA) and Project Prospectus as part of the construction obligation package submitted to WSDOT. b.It is anticipated that obligation must be approved by WSDOT by June 1, 2025 •The project is funded with federal funding and must be designed to meet all federal funding requirements. The project will meet all LAG manual requirements and the Consultant will assist the City with WSDOT Local Programs coordination as required for federally funded projects .. •Traffic signal modifications are not anticipated or included in the scope.•Removal of one traffic lane in each direction may be considered and accepted by the City of Renton. An amount of funding has been allocated to the collection of current traffic counts and a traffic analysis to evaluate the feasibility of a lane removal. •No modification to illumination is included in the scope. •A raised intersection may be considered at SW 20th Street and/or SW 27th Street. Additional assumptions specific to each task are included where necessary. Task 1 -Project Management 1. 1 Project Coordination The Consultant project manager will coordinate with the City's project manager on a regular basis (weekly or bi-weekly) throughout the duration of the project. The coordination will address project scope/status, technical and policy direction, budget, schedule, and meetings with additional stakeholders. Coordination will be via video chat, telephone calls, and email, as appropriate. The Consultant team project manager will also coordinate with subconsultants on a regular basis regarding project scope/status, project direction, budget, and schedule. 1.2 Progress Reports and Invoicing Detailed progress reports and invoices will be prepared on a monthly basis and provided to the City. 1.3 Design Meetings The Consultant will conduct meetings at the following project milestones with the City Project Manager. For efficiency of resource usage, all meetings are assumed to be video conferences, unless otherwise stated or arranged by mutual agreement between the City and Consultant. The Consultant shall prepare a meeting agenda for each meeting. It is assumed that the Consultant will not be required to distribute meeting minutes following each meeting, but will keep an internal record of minutes. This will not preclude as-needed communication by the Consultant with the City or Subconsultants to confirm understanding of issues raised in these meetings. 1.Project Kickoff (on site meeting in Renton) a.Including field visit/site walk with City project manager and staff 2.Design alternatives coordination meeting 3.Preliminary (50%) Design Review & Comment Resolution Other design meetings may be necessary to discuss alternatives for specific project elements or provide updates on field conditions located by the Consultant and Subconsultants which may affect project designs. Additional meetings with the City will be held via phone or video conference, to the extent possible, with the goal of minimizing expense. Additional in-person meetings may be held at the request of the City, but may require adjustment to the scope of services, fee projection and schedule. These meetings do not preclude regular communication via email and phone between the City and the Consultant regarding project concerns and progress. The Consultant will conduct two field visits. The first field visit will coincide with the Project Kickoff. Other field data may be gathered by City staff if available, or during the second field visit. The Consultant anticipates conducting the second field visit after the completion of the 10% design phase. 1.4 Project Schedule The Consultant will provide a project schedule to the City and maintain the schedule with monthly updates on progress and affected milestones. The schedule will show milestone dates and events necessary to complete the plans and special provisions to complete the design of all the project improvements. The anticipated overall schedule for this project is 12 months, with a kickoff in August 2024 and an anticipated completion of the bid phase by August, 2024. Task 2 -Alternatives Analysis & Conceptual (10%) Project Design 2. 1 Alternatives Analysis The primary element of the scope of work, the overlay of Oakesdale, is not subject to an alternatives analysis. Replacement of curb ramps, as required for the overlay, may change subject to the results of an alternatives analysis related to the future channelization on the overlaid roadway. The Consultant understands that the City of Renton has not selected the final form and detailed design of the rechannelization or surface level channelization devices that may be placed after the overlay in the project corridor. The preferred alternative will provide additional protection and comfort for cyclists on Oakesdale and provide traffic calming elements. The channelization improvements could include, but are not limited to: •Road diets, and lane reductions to not less than one lane per direction on Oakesdale •Reduced lane widths •Rumble strip-enhanced bike buffers •Surface-mounted curbs with asphalt fills to create raised medians and buffers All of the channelization modifications, would be, at the City's election, subject to a traffic analysis (see Task 2.2) that would follow the safety, feasibility and geometric development of potential rechannelization alternatives. A combination of the benefits and tradeoffs identified in the traffic modeling, safety analysis, geometric analysis, and meetings between the City project manager, City staff and the Consultant, shall result in the selection of a preferred alternative. The alternatives process will assume; •A minimum lane width of 10.5' •Improvements will be within the existing curb-to-curb width •No new "subsurface" elements, such as new curb and gutter or replacement of asphalt with trees or other planted buffer treatments are included without modification of the scope and fee •Traffic impacts, as identified in Task 2.2, may be acceptable if a facility has strong safety and connectivity benefits for active mode users. •The City must meet the requirements of the grant commitments. Consultant Deliverables •Technical memorandum summarizing o All alternatives considered o Evaluation criteria o Traffic analysis conducted (see Task 2.2) o Process for selecting a preferred alternative 2.2 Traffic Analysis Using traffic models provided by the City, historical traffic data provided by the City, and new traffic data acquired as part of Task 04, the Consultant will provide a traffic analysis of the impacts of any alternatives that are determined to be feasible and are to be considered by the City. The traffic analysis will include assessment of level of service, seconds of delay and queue lengths, compared to existing conditions, to determine the impact of an alternative. 2.3 Conceptual 10% Design As part of the development of alternatives that are considered the most feasible, the Consultant will prepare cross sections and exhibits that depict channelization to visualize the impact the overlay and channelization alternative will have on the corridor. For the preferred alternative(s), the conceptual exhibits will serve as the 10% design drawings. The 10% design will consider: •Overlay paving layouts and engineering-level cross section(s) •Verify improvements are within the right of way and curb to curb•Impacts to intersections and driveways •Channelization of intersections and crossings •Critical and custom signage Assumptions: •Removal of a lane of traffic for traffic calming benefits, and/or safety and comfort benefits for active mode users is acceptable to the City, with a data-based traffic analysis to identify traffic impacts. •Cost of alternatives will not exceed identified city funding (federal funding, TIB funding and local funding). TIB funding levels may not be known until November, 2024, but is assumed to be available to the City for the conceptual design level. Consultant Deliverables •Conceptual 10% design level corridor plans including: o Cover sheet with vicinity map o Typical roadway sections with lane and buffer widths o Striping and critical signing •Planning level cost estimate •Design Report documenting design decisions and standard references, as applicable Task 3 -50%, 90% and 100% Design Plans, Specifications, and Estimates (PS&E) The Consultant will prepare and submit to the City for review and comment, design plans, specifications, and estimates (PS&E) for: •50% level of design •90% level of design •100% level of design Plan sheets will be developed at a 1 "=20' full size scale that allows for approximately 500 feet per plan "window''. Two plan windows will be used on sheets where feasible to reduce the total number of sheets and proposed work can be clearly and concisely conveyed to contractors. Topics may be combined on sheets, as listed or per City approval to reduce the total number of sheets in the final package, but completeness and clarity will be prioritized over sheet count. The Consultant will submit the design plans for review by the City. The City's review will identify issues, resolve problems, recommend modifications, suggest actions required and provide direction and guidance for the next stage of design. The City will closely monitor the design plan preparation process and be responsive to communication from the Consultant to assist in avoiding substantial revision during the review process. This effort shall not alter the Consultant's responsibility for the work. The Consultant will prepare the special provisions and applicable amendments to the contract provisions, Divisions two through nine, as required for the improvements. The Consultant will prepare the Division one specifications. The Consultant will compile the final specifications for bid. The contract provisions shall be prepared in accordance with the requirements of WSDOT and the City of Renton. The Consultant shall prepare special provisions for those items not covered by the standard specifications, general special provisions or amendments. The Consultant will prepare quantity estimates and backup calculations in accordance with the WSDOT bid item descriptions. Final quantity estimates will be prepared according to WSDOT format and backup calculations for lump sum and unit price items will be provided. Quantity estimates will be used to prepare the summary of quantity sheets, and all other material required for construction. Quantities will be combined into a single bid package. The Consultant will maintain a construction cost estimate throughout the project, updated at each design milestone. The estimate will be developed in Excel format. All electronic materials used to generate the Bid Set Plans, Specifications and Estimate will be submitted to the City. Drawings will be submitted in PDF and AutoCAD/AutoCAD Civil 3D format.
