Item 4G - MemoItem 4G CITY OF SOUTHLAKE MEMORANDUM (September 20, 2022) To: Shana Yelverton, City Manager From: Rob Cohen, Director of Public Works Subject: Reject all bid proposals for the Water Distribution System & Sidewalk Improvements at S. Pearson Lane & Union Church Road, E. Dove Road, and Oak Bend Court project. Action Requested: Reject all bid proposals for the Water Distribution System & Sidewalk Improvements at S. Pearson Lane Union Church Road, E. Dove Road, and Oak Bend Court project. Background Information: This project included improvements along S. Pearson Lane & Union Church Road, E. Dove, and Oak Bend Court. Solicitation of bids for this project began on March 27, 2022, and one sealed bid was received and opened on April 26, 2022. The lone bid received for this project is shown below in bid tabulation: Bidder Bid Amount Canary Construction $ 2,348,707.00 The designer -produced Opinion of Probable Construction Cost (OPCC) of this project was $1,606,000.00. One sealed bid was received above the OPCC value. The consultant attributed discrepancies between the OPCC and bid to a uniform increase in materials cost and an unusually high increase in the cost of concrete and sod (sidewalk construction). City review of current concrete flatwork prices and landscape restoration, including contingencies agrees with this assessment. Due to bid exceeding the authorized project amount, the bid prevents the project team from selecting a best value bidder. Additional funding was requested in the FY 2023 budget. This project will be re -advertised for best value bids this fall, for award winter 2023. Financial Considerations: None.
