Subject: Proposal for Professional Engineering Serv ices for Design and Construction Support to Complete the Final PS&E for the Studebak er Road and Rosecrans Avenue Hot Spots Arterial Intersection Improvement Plans (Revised)
Dear Mr. Mera:
Pursuant to the Professional Services Agreement (“A greement”) between the City of Norwalk and Willdan Engineering (Willdan), and our current contract to design the Studebaker Road and Rosecrans Avenue Hot Spots Arterial Intersection Improvement Plans, we are pleased to provide this proposal for the requested professional engine ering services for design and coordination needed to finalize the bid package of the Rosecrans at Studebaker Hot Spots intersection.
In order to proceed with the restart of the project , the scope of work will be expanded. For design engineering, Willdan will need to:
• Complete new utility coordination
• Perform a site visit
• Review the survey to verify existing conditions
• Complete a new supplemental survey due to the new development • Complete the design of the project
Due to the 4-year delay of the project, Willdan has to refamiliarize with the prior scope of work, project notes and instructions, design complete to date, and update the plans, specifications, and construction estimate to current standards and requirements.
Due to the changes in our scope of work and the revisions to the project, we respectfully request an increase in our fee to complete the final PS&E for the Studebaker Road and Rosecrans Avenue Hot Spots Arterial Intersection Improvement Plans.
We assume the original alignment will remain the sa me and the City will complete all coordination for the power pole relocation with SCE and the telecom companies. The conflicting portions of existing abandoned shallow concrete culverts are assumed to be removed.
We have also added tasks for construction support to be added to the scope.

SCOPE OF WORK
Task 1 – Project Management
1. Conduct day-to-day project management, meetings, pr ogress reports, project communication and agency follow-up, project schedul ing and tracking, invoicing, and overall administration of the project.
2. Attend a pre-design (kick-off) meeting with City re presentatives to review the project in detail and to determine requirements and procedures for design, ongoing review, coordination, and meetings.
3. Maintain continuous communication with the City of Norwalk Project Manager, including meetings to review project status at 90%, and 100% completion.
4. Provide agendas of special items for discussion, and minutes listing agreed actions.
5. Provide project schedule with updates.
6. Maintain continuous awareness of the status of each task as it proceeds and make provisions to expedite and resolve any difficulties that may impede progress.
7. Proactively initiate communications with City Proje ct Manager and/or staff when questions arise due to inconsistency in the flow of work production.
8. Respond to questions during project advertising phase.
Task 2 – Utility Coordination
1. Provide utility coordination, including notices to all utility companies in accordance with City’s procedures. All documentation of contacts and responses will be copied to the City.
Willdan will prepare utility notices and deliver th em to the City for mailing under City letterhead. If so desired by the City, Willdan can transmit these notices under Willdan’s letterhead; however, the City shall be responsible for any fees assessed to Willdan by the utility companies. In either case, all responses, questions, and correspondence from the utility companies will be addressed to Willdan’s Utility Coordinator.
2. The city will continue the coordination with SCE and telecom for relocation of the power pole.

Task 3 – Preliminary Investigation
1. Obtain available as-built drawings, survey data and utility contact information from the City. The research may include assessor parcel map s, tract maps, recently completed or planned improvement drawings, as-built drawings for street, signing, striping, and storm drain, as well as municipal improvements such as wa ter and sewer as-builts, atlases, and/or GIS information.
2. Conduct a field investigation to verify existing topographic conditions and identify unusual or special conditions, if any.
Task 4 – Plans, Specifications, and Estimates
1. Update the project improvement plans to address all of the City’s comments on the plans.
Willdan will conduct a site visit to confirm the li mits of all proposed repairs, and to incorporate all changes in existing conditions.
2. Prepare a detailed engineer’s estimate in Microsoft Excel spreadsheet format. The items will be arranged in chronological order of construction. The estimate will be based upon recent bid prices for similar projects as maintained by the City and Willdan.
3. The City will provide Willdan with its boilerplate specifications and general technical provisions in Microsoft Word format. Willdan will be responsible for compiling the project specifications, signed by a civil engineer registered in the State of California, which are complete and ready for bidding purposes. The l atest edition of the Greenbook (Standard Specifications for Public Works Construction and subsequent amendments) will be used on the project, except for traffic design. The technical portion of the Caltrans Standard Specifications will be used for the traffic design.
4. Submit plans, specifications, and cost estimates to the City for review and comment at the 90%, 100% and Final Submittals.
5. Upon receipt of final comments, make final revision s and submit final plans plotted on mylar for City advertisement and bidding.
Task 5 Topographic Survey
1. Perform topographic ground surveys necessary to des ign the median and turn pocket improvements. The ground survey will establish hor izontal control (local and assumed), vertical control (NAVD 88), centerline control, identification of survey monuments, visible surface utilities, curbs and gutters, edge of pavem ents, and grade breaks. Supplemental shots in identified areas of concern based upon preliminary engineering will be provided.
November 18, 2025
The design survey will extend 20’ beyond the propos ed improvements. The survey will provide topo, including spot elevations, all hardscape features, landscape and vegetation, street crown, edge of pavement, lip of gutters, flo w line, top of curb, sidewalk, and crosswalk striping at 50’ cross sections. This survey will encompass the new development and any pavement adjustments that were made since the original survey was completed in 2018. A digital topographic map will be produced.
Task 6 – Construction Engineering
1. Respond to questions during project advertising and bidding phase.
2. Prepare project addenda, as necessary.
3. Attend the pre-construction meeting and respond to questions regarding the construction documents.
4. Review and approve material and equipment submittals to verify compliance with project specifications.
5. Answer contractor’s request for information during the construction period.
