Title
Resolution to Approve Change Order No. 1 with Douglas N Higgins, Inc. for the Ferdon Wells Storm Sewer Rehabilitation Project ($81,247.39; Bid No. 4433)
Memorandum
Attached for your review and approval is a change order to the Construction Contract with Douglas N Higgins, Inc. (Bid No. 4477) for the Ferdon Wells Storm Sewer Rehabilitation Project.
This project installed approximately 785 feet of storm sewer within Ferdon Road and Wells Street. The original intent of the project was to resurface one half of the road surface within Wells Street directly impacted by the storm sewer trench. During construction, it became clear that the remaining pavement within Wells Street was not stable and deteriorated significantly during construction operations. A full width resurfacing of Wells Street between Baldwin Avenue and Ferdon Street was performed and resulted in an increase of approximately $48,436.56 increase to the contract.
In addition, this change order adds the installation of two fire hydrants along Newport Road, which would provide adequate fire hydrant coverage to existing homes along Newport Road. Douglas N Higgins, Inc. submitted a quote of $28,517.00 to complete this work. The contractor’s quote was reviewed by Public Works staff and found to be a reasonable price for performing the work. The hydrant installation work will be performed after the approval of this resolution.
