Approval of the Final Contract with Dalton Electric Corp. and Acceptance of Construction, in the Amount of $1,197,328, for the Pump VFD Replacement Project
OVERVIEW STATEMENT:
recommendation
Public Works is requesting Council to approve the final contract and accept construction for the Pump Variable-Frequency Drive (VFD) Replacement project (No. 2016). This contract with Dalton Electric Corp. had a base bid amount of $1,240,763.68, plus or minus change orders and bid items increases or decreases, resulting in a final contract amount of $1,197,328.
Variable Frequency Drives control the frequency of the electrical power to water and wastewater pump stations. This project replaced the VFDs at Pump Stations 3 and 5, Novelty Hill Pump Station, Novelty Hill Operations Center, and Wastewater Lift Station 51. Many of the VFDs were at the end of their useful life and were in need of replacement.
The proposed acceptance date for the project has been delayed two years from substantial completion due to power module failures in the VFDs that occurred after substantial completion. Once the failed part was identified, the City and Contractor agreed to delay acceptance so the VFDs could run and allow the City to be assured the replaced parts performed satisfactorily.
