Pursuant to Resolution 2024-008, bids were opened on March 6, 2024. On April 8, 2024, City Council approved Resolution 2024-022 Awarding the 2024 PMP Street and Utility Improvements Contract to S.M. Hentges & Sons, Inc. in the amount of $2,238,418.15. Upon reclamation of Royal Hills Drive, it became apparent that the subgrade on that street was severely unstable and could not pass compaction testing in order to get the roadway in that location put back together and paved. A number of different options were discussed including farming the soil to dry it out, complete selective subgrade corrections, or cement stabilization, which was ultimately selected as the best quality option and also the most cost-effective option. For more detail, the items outlined for this Change Order are within Bolton and Menk's Memo (Attachment A). Attachment B is Change Order #1, which summarizes the total labor and materials required to perform this unforeseen subgrade stabilization. Staff recommends that Council approve Change Order No. 1, an increase of $40,903.03. The project is approximately 55% complete. Items completed to this point include James Ave work (including the base paving and restoration of green space), spot curb replacement throughout, the reclamation/milling operations, half of the pond dredging scope, and the storm sewer retrofits throughout. Five percent is being withheld from the work completed in accordance with the contract documents. Payment No. 3 is in the amount of $495,491.20. Staff recommends that Council approve Payment No. 3.
