properties and is proposed to be reconstructed to a 10-ton design as is typical for commercial streets. Rivlyn Avenue is a residential street and is proposed to be reconstructed to the standard neighborhood pavement section. This will be further explored during project design,which will include obtaining a geotechnical report of the project area. Requests for proposals for the report have been sent out, and are anticipated to be brought to the August 13, 2024, City Council meeting for approval. The cul-de-sac at the west end of Rivlyn Avenue is only partially within City-owned right of way. During design options for addressing this will be explored and recommendations will be presented to City Council at a later meeting. Staff will work with the property owners and determine if additional right of way may be purchased, if the length of the cul-de-sac may be shortened, or another solution is appropriate. Project Timelines Staff is proposing to not prepare plans and specifications for this project. A proposal from Bolton&Menk, Inc. for engineering design services, including preparing final plans and specifications, is attached to this case. The following are the proposed general project timelines: July 23 2024 City Council authorization to prepare plans and specifications Aug—Sep Geotechnical investigation(RFP) and topographic survey(Bolton&Menk) Oct 2024—Jan 2025 Prepare plans and specifications (Bolton&Menk) Jan-Feb 2025 City Council approves plans, authorizes bidding Feb—Mar 2025 Bid opening, City Council awards contracts May—June 2025 Begin Construction Summer 2025 Finish Construction Bolton&Menk Design Services Due to the 2025 project design workload as proposed in the 2024—2033 CIP, City Staff does not have the capacity to prepare plans and specifications for these improvements in time to bid the project in late winter/early spring and be ready for early season construction. Bolton&Menk has provided a proposal for engineering design services including; coordinating project investigation,topographic survey,project design,preparation of project documentation and final plans, and project bidding. The proposal does not include construction inspection or construction administration. Bolton&Menk prepared the plans and specifications for both the Riverdale Drive reconstruction in 2021 and the Gateway Highway 10 Improvements which are currently under construction,both of which tie into this project, and make them uniquely familiar with the project area and associated design requirements. The proposal total not-to-exceed cost for Improvement Project 25-04 is $68,537, and is included in the 23-percent indirect project costs associated with these improvements. This project is proposed to be constructed as a stand-alone project. Staff proposes to bid and award 2025 projects as close together as practical,which generally allows for a better bidding environment for the City. This project is necessary, feasible, and cost-effective from an engineering standpoint, and can be constructed as proposed herein. Notification: If City Council orders plans and specifications for this improvement project, Staff will send notification letters to residents impacted by these improvements. Time Frame/Observations/Alternatives: Observations: Estimates are CIP level and will be updated during the design process. Alternatives: Motion to adopt Resolution#24-196 Ordering Plans and Specifications for Dickenson's Mississippi Estate Street Reconstructions, Improvement Project#25-04 Funding Source:
