An alternative "reclamation light" project design has been discussed as a way to gain useful life out of the streets. The design process would include reclamation of the existing bituminous and aggregate base, removal of 2-inches of reclamation material and placement of 2-inches new bituminous pavement. This would leave a pavement section of 2-inches bituminous pavement over approximately 5-inches recycled aggregate base. The intent of this process would be to avoid any restoration needs of the boulevards and adjacent driveways. Staff performed an estimate for this process, with the total project costs, including 10-percent contingency costs and 23-percent indirect costs, of 5630,OOO. This is approximately 43-percent of the estimated cost of the proposed street reconstruction. Alternatives: Alternative #1— Motion recommending City Council approving plans and specifications and authorizing advertisement for bids for Autumn Heights Street Reconstructions, Improvement Project #22-02. Alternative #2 — Motion of other. Funding Source: Funding for this improvement is proposed to come from Pavement Management Funds and Stormwater Utility Funds. Staff has completed an estimate based on the final plans and anticipated 2022 construction costs, with a total estimated project cost of $1,475,337.15, which includes 23-percent indirect costs for administrative, engineering, finance, and legal costs. • Street Project Costs $1,379,587.80 • Storm Sewer Project Costs $95,749.35 • Total Estimated Costs $1,475,337.15 Recommendation: Staff recommends Alternative #1 to maintain a consistent pavement design on all recently reconstructed streets. Alternatively, the Committee could recommend revising the plans to include the "reclamation light" design at an estimated 43-percent cost savings. However, these streets would then have a different design than all other recently reconstructed streets in Ramsey, which would provide a lesser pavement design strength and a shorter design life. Action: Motion recommending City Council approving plans and specifications and authorizing advertisement for bids for Autumn Heights Street Reconstructions, Improvement Project #22-02.
