SUPPLEMENT NO. 3 DESIGN MODIFICATIONS, BID & CONSTRUCTION SUPPORT  CITY PROJECT NO. 315026  FEDERAL AID NO. STPUL‐9918(017)  March 17, 2022    Introduction:  The following Scope of Work delineates supplemental tasks to be performed in addition to the original  agreement between Skillings, Inc. (Consultant) and the City of Bremerton (City).    Skillings, Inc. has been selected by the City of Bremerton to provide design engineering, environmental, and  right‐of‐way acquisition services for the reconstruction of Washington / 11th from the Manette Bridge to  Pacific. In addition to that project, the City previously added work to improve the existing sidewalk adjacent  to the lower portion of Washington Avenue (Lower Sidewalk). Northbound Washington Avenue splits into  an upper and lower section after the Washington Avenue/Manette Bridge intersection. The City also  intends to upgrade the water mains within the vicinity of the two intersections of 11th Street at Pleasant  Avenue and Highland Avenue.    Based on comments from residents adjacent to the project, the City intends to revise the previously  completed alignment of the Washington / 11th Street, redesign of the roadway, and replacement of the  existing rockery wall on the west side of Washington Avenue with a new CIP or soldier pile wall. Work along  the lower portion of Washington Avenue will consist of redesign to reflect the parallel parking option  presented to the community which includes improvements to curbs, road surface, a 4‐ft sidewalk with ADA  turnouts, and storm drainage.    Project Assumptions:  This scope of work is based on the following general assumptions:   The project will be developed as a single package. Bid alternates, bid additives, or subsequent  repackaging of the project into separate phases is not included.   Landscaping and irrigation design are not included in this scope of work or fee.    It is assumed that there are no contaminated soils within the project limits.     WORK ELEMENTS    Task 301 – Geotechnical Investigations for Wall  Consultant will contract with HWA GeoSciences, Inc. (HWA), Subconsultant, to provide supplemental  geotechnical investigation and design parameters for the new wall replacing the existing rockery wall along  the west side of Washington Avenue.      PROJECT BACKGROUND   At this time HWA has submitted a draft report for which most of our scope was completed, except for the  design of the wall that was proposed along the eastern side of the roadway alignment. At this time, we  understand that the wall along the east side will be instead consist of widening the sidewalk and  DocuSign Envelope ID: A6A79D2F-08F8-4BAD-8C16-8E0222062D51

reconstructing retaining walls along the west side of the sidewalk. Walls are anticipated to have exposed  wall heights between 4 to 7.5 feet. Geotechnical services associated with evaluating suitable wall types for  wall construction are desired to complete the design for the sidewalk. To provide these support services,  we propose the following tasks:      HWA Internal QA/QC for Geotechnical and Pavement Tasks: HWA will have all design calculations  and recommendations reviewed by a senior principal prior to distribution to the design team.    Task Coordination and Management: HWA will provide geotechnical task management to all  geotechnical related aspects of the project and will correspond with Skillings and the design team  in the form of emails, fax, and telephone calls, as necessary. HWA will also prepare monthly  invoices, and progress reports for the duration of the design phase of the project.   Site Reconnaissance: HWA will make one site visit to observe the existing site conditions along the  sidewalk alignment where the proposed walls will be installed.    Review Proposed Wall Cross‐Sections and Evaluate Constructability of Wall Alternatives: Based  on data supplied to HWA for proposed wall locations, heights, and roadway proximity, HWA will  evaluate the suitability of using either cantilever walls or soldier pile walls. Recommendations for  each suitable option will be provided to be incorporated into design of the proposed  improvements.    Wall Alternative 1, Cantilever Wall Design Parameters: For walls determined to be constructed as  cantilever walls, HWA will develop design active and seismic earth pressures, nominal and service‐ level bearing capacities, sliding resistances, and perform global stability checks.    Wall Alternative 2, Soldier Pile Design Parameters: For walls determined to be constructed as  soldier pile walls, HWA will develop design earth pressure diagrams and minimum  recommendations for pile spacing and widths for passive pressures.    Provide Recommendations for Temporary Excavations and Shoring: HWA will provide input for  temporary excavations and shoring, as they relate to wall construction.    Provide Earthwork Considerations for Construction: HWA will provide input for earthwork  considerations as it relates to subgrade preparation and type and placement of backfill behind  walls.    Provide Miscellaneous Consultation for Implementing Geotechnical Recommendations: HWA will  provide additional support as needed for the implementation of geotechnical recommendations  during design and construction.    Update Existing Geotechnical Report for Wall Alternatives: HWA will update the existing draft  geotechnical report with proposed recommendations for the wall alternative described. Once we  receive comments, we will incorporate them into a Final Geotechnical Report for the Project.    Review PS&E Documents: HWA will review PS&E documents for design consistency with our  geotechnical recommendations.     DELIVERABLES   One deliverable is anticipated for the new scope of work:    Revised Draft and Final versions of the Geotechnical Report     DocuSign Envelope ID:

Lee, P.E. Subject: SUPPLEMENTAL SCOPE OF WORK GEOTECHNICAL ENGINEERING SERVICES Bremerton Roundabout at Washington and Manette with Improvements on 11th Street Bremerton, Washington Dear Mr. Lee, Thank you for the opportunity to present this proposal for HWA GeoSciences Inc. (HWA) consulting services. As requested, HWA has prepared the following supplemental scope of work and associated cost estimate for geotechnical engineering services in support of the Bremerton Roundabout and 11th Street Improvements project in Bremerton, Washington. The work scope and cost estimate are based on our present understanding of the work to be accomplished, established in our prior correspondence regarding the project. PROJECT BACKGROUND At this time HWA has submitted a draft report for which most of our scope was completed, except for the design of the wall that was proposed along the eastern side of the roadway alignment. At this time, we understand that the wall along the east side will be instead consist of widening the sidewalk and reconstructing retaining walls along the west side of the sidewalk. Walls are anticipated to have exposed wall heights between 4 to 7.5 feet. Geotechnical services associated with evaluating suitable walls types for wall construction are desired to complete the design for the sidewalk. To provide these support services, we propose the following tasks: • HWA Internal QA/QC for Geotechnical and Pavement Tasks: HWA will have all design calculations and recommendations reviewed by a senior principal prior to distribution to the design team. • Task Coordination and Management: HWA will provide geotechnical task management to all geotechnical related aspects of the project and will correspond with Skillings and the design team in the form of emails, fax, and telephone calls, as DocuSign Envelope ID: A6A79D2F-08F8-4BAD-8C16-8E0222062D51 March 7, 2022 HWA Proposal No. 2019-149-21 2019-149-21 Bremerton Roundabot Supp Scope Western Wall 2 HWA GEOSCIENCES INC. necessary. HWA will also prepare monthly invoices, and progress reports for the duration of the design phase of the project. • Site Reconnaissance: HWA will make one site visit to observe the existing site conditions along the sidewalk alignment where the proposed walls will be installed. • Review Proposed Wall Cross-Sections and Evaluate Constructability of Wall Alternatives: Based on data supplied to HWA for proposed wall locations, heights, and roadway proximity, HWA will evaluate the suitability of using either cantilever walls or soldier pile walls. Recommendations for each suitable option will be provided to be incorporated into design of the proposed improvements. • Wall Alternative 1, Cantilever Wall Design Parameters: For walls determined to be constructed as cantilever walls, HWA will develop design active and seismic earth pressures, nominal and service-level bearing capacities, sliding resistances, and perform global stability checks. • Wall Alternative 2, Soldier Pile Design Parameters: For walls determined to be constructed as soldier pile walls, HWA will develop design earth pressure diagrams and minimum recommendations for pile spacing and widths for passive pressures. • Provide Recommendations for Temporary Excavations and Shoring: HWA will provide input for temporary excavations and shoring, as they relate to wall construction. • Provide Earthwork Considerations for Construction: HWA will provide input for earthwork considerations as it relates to subgrade preparation and type and placement of backfill behind walls. • Provide Miscellaneous Consultation for Implementing Geotechnical Recommendations: HWA will provide additional support as needed for the implementation of geotechnical recommendations during design and construction. • Update Existing Geotechnical Report for Wall Alternatives: HWA will update the existing draft geotechnical report with proposed recommendations for the wall alternative described. Once we receive comments, we will incorporate them into a Final Geotechnical Report for the Project. • Review PS&E Documents: HWA will review PS&E documents for design consistency with our geotechnical recommendations. DELIVERABLES One deliverable is anticipated for the new scope of work: • Revised Draft and Final versions of the Geotechnical Report DocuSign Envelope ID: A6A79D2F-08F8-4BAD-8C16-8E0222062D51 March 7, 2022 HWA Proposal No. 2019-149-21 2019-149-21 Bremerton Roundabot Supp Scope Western Wall 3 HWA GEOSCIENCES INC. ASSUMPTIONS • No explorations will be performed in the project area for retaining wall evaluation as the data from the previous borings performed for the project will provide design information. • HWA will respond to one (1) round of comments on the revisions to the draft geotechnical report. • The scope of work is related solely to geotechnical engineering evaluation of site soil and ground water, as they relate to geotechnical design for the project improvements. Neither identification nor evaluation of contaminants that may be present in the soil or ground water is included in this scope of work. PROJECT COST ESTIMATE We estimate that the scope of the new services proposed herein will require a budget of $22,705 to accomplish, as detailed on the attached project cost estimate spreadsheet. HWA currently has a remaining budget of $13,530. Subtracting the remaining budget from the budget of new and remaining work, we get a total supplement request of $9,175. We will not exceed the above cost estimate without your prior authorization. However, if during the evaluation of the available data or during our field reconnaissance unanticipated subsurface conditions are revealed which would require a level of effort beyond the scope of our study, we will contact you immediately to discuss any necessary modifications to our scope of services and/or budget estimate. The budget presented in this proposal reflects an estimate based on our current understanding of the project requirements for a scope of work developed from information provided. HWA reserves the right to transfer hours and budget dollars between tasks to satisfy project requirements. HWA may also transfer funds allocated for direct costs to professional/technical hours or vice versa, to satisfy project requirements.    DocuSign Envelope ID: A6A79D2F-08F8-4BAD-8C16-8E0222062D51 March 7, 2022 HWA Proposal No. 2019-149-21 2019-149-21 Bremerton Roundabot Supp Scope Western Wall 4 HWA GEOSCIENCES INC.

Via Email to: ilee@skillings.com RE: Washington Avenue Retaining Wall - Structural Engineering Services Proposal Project No.: A22100.00 Dear Ian: On behalf of Sargent Engineers, I am pleased to present to you our proposal for providing structural engineering services for the retaining wall that will be part of the Washington Ave & 11th Street Intersection Improvements that Skillings is designing for the City of Bremerton. As part of the improvements, the City would like to replace a rockery wall that currently runs along the east edge of the corridor. Sargent will provide the structural design of the new retaining wall as a subconsultant to Skillings. The retaining wall is anticipated to be a soldier-pile wall with concrete fascia, with height ranging from 4-8ft. We will perform the structural design of the soldier pile wall per the requirements of the project geotechnical report, AASHTO LRFD Specification for Bridge Design, the WSDOT Bridge Design Manual, and the WSDOT Geotechnical Design Manual. We will prepare the retaining wall elevation sheet and structural detail sheets needed to construct the wall, including up to two typical wall sections. The typical wall sections will show the maximum retained soil height, pile size and spacing, and concrete fascia thickness and reinforcing. Skillings will prepare the wall plan sheets and will provide the surface profile for finish grade at the back of wall, which Sargent will use to prepare the wall elevation sheets. We will prepare the quantities, cost estimate, and technical special provisions for the structural items in WSDOT format. We will also respond to Skillings, City of Bremerton, and WSDOT review comments. To complete the scope of work described above, I propose a maximum fee of $14,758 to be billed at our approved hourly rates. If the scope and fee are acceptable, we can begin working on the design as soon as we receive the geotechnical information and wall profile from Skillings. Assuming we receive this information by March 18, 2022, we anticipate being able to provide the completed wall plans, specifications, and cost estimate for you to include in your April submittal to WSDOT. Thank you for this opportunity to be of assistance to you, and we look forward to another successful project working with Skillings. Respectfully, Sargent Engineers, Inc.
