overlay of the existing pavement is appropriate. The proposed mill and overlay will be 2-inches thick throughout the project area. Staff review found the existing pedestrian ramps within the project area did not meet current ADA requirements, therefore all pedestrian ramps within the project area will need to be removed and replaced. The concrete curb and gutter along Riverdale Drive was found to be in very poor condition. Due to the amount of curb that would require replacement, and Staff's expectation that the curb and gutter will be serviceable for 15 to 20 years until a full street reconstruction will occur, this project is proposing to focus efforts on the pavement and not perform curb and gutter repairs beyond what is necessary for installing the ADA compliant pedestrian ramps. The concrete curb and gutter within the Rivenwick 3-d and Rivenwick Village subdivisions was found to generally be in good condition, and only spot repairs are proposed. Minor repairs to the existing storm sewer structures are proposed with this project, the majority of which are grouting the existing adjustment rings and pipe inverts. Some storm sewer catch basins will require resetting due to settling. The sanitary sewer castings along Riverdale Drive were found to be an older, heavier model no longer installed within the City. At the request of the Utilities Department, Staff is proposing to replace the 14 castings along Riverdale Drive to the currently specified model. Preliminary Schedule Remaining • Council Awards Contract to the lowest responsible bidder o July 25, 2023 • Contractor begins construction o August 2023 • Contractor Substantially Completes construction o September 29, 2023 • Contractor Final Completion (verify final restoration, punch list created) o October 13, 2023 State Aid Approval The plans and specifications have received MnDOT State Aid approval. The construction costs and indirect costs for work within the Riverdale Drive right of way are eligible state aid funds, except for any sanitary sewer or watermain construction costs. Final plans are not attached to this case to prevent potential bidders from downloading plans attached to the case to prepare and submit their bids, rather than purchasing the plans through QuestCDN, the electronic bidding software used by the City of Ramsey. This ensures all bidders are bidding off the same set of plans, and all bidders are notified of any plan revisions (addenda) issued during the bidding process. Attached is the title sheet showing the scope of the improvements, as well as a plan sheet showing the typical sections, which includes information on the proposed pavement section. Plans are available upon request from the City Engineer. Notification: If Council accepts the bids and awards a contract for construction of the improvements, letters will be mailed to property owners with updates on the project status. Engineering Staff maintains City Improvement webpages with the most current project information, this can be found on the City website, Engineering department page. Time Frame/Observations/Alternatives: Alternatives: Alternative #1 — Motion to adopt Resolution #23-169 accepting bids and awarding contract for 2023 MSA Pavement Overlay Improvements, Improvement Project #23-06.
