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

received and opened on April 26, 2022. The lone bid received for this

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.
