Title
Consideration to Accept Public Improvements and Accept Final Payment - WWTP Replacement Well.
Body
Action Requested:
Staff recommends approval of the Resolution Accepting the Public Improvement and Approving the Final Payment for Project WSTR2015-J03 - WWTP Replacement Well.
Summary Report:
The City Council is being asked to accept the public improvements for the WSTR-J03 - WWTP Well Replacement. Additionally, Council is being asked to approve the final payment in the amount of $7,522.88. The construction contract was awarded to Keys Well Drilling Company of St. Paul, MN at the September 15, 2015 City Council meeting in the amount of $154,835.00. Through the course of construction there was one Change Order executed to install a temporary six inch discharge pipe, cover with class 5 fill, and install erosion control at discharge point for $1,950.00.
Quantity adjustments are typical with construction due to field conditions and differing site conditions that can affect final cost of the project. These changes can result in either increased or decreased costs to the project. In general, these changes to overall quantities are the result of field adjustments necessary to accommodate unknown or unforeseen conditions. For this particular project, the overall amount of sandstone removal, explosive development and drilling and driving of casing used to complete the well were less than originally estimated. The net decrease of $23,377.50 represents a reduction of slightly more than 15% from the original contract (Attachment 2).
This project has been reviewed by the Public Works staff and is recommended for acceptance. The Certificate of Final Acceptance (Attachment 3) and the Final Pay Request (Attachment 4) are included along with the resolution (Attachment 1).
Alternative Options:
This project is completed and the final acceptance and payment are needed to close out the contract.
Financial Impacts:
This project was funded through the Wastewater Enterprise Fund.
Tentative Timelines:
Upon acceptance by the City Council, the final payment will be processed and sent to the contractor. At that point a two year maintenance bond will begin if warranty work is needed.
