CO2 to the Wastewater Pump Station Upgrades Phase I project
To approve Change Order 2 to the Pump Station Upgrades Phase I contract with DeFelice
Corporation of Dracut, MA in an amount not to exceed $27,235.18 for additional
electrical upgrades needed at Newton pump station. Funding will be through Department
169-Wastewater; Fund: SRF Loan; Activity: Pump Station Upgrades Phase I.
Change Order 2
The Pump Station Upgrades Phase I project is for renovations to 6 of the 13-pump station
in the City. The project was awarded to the DeFelice Corporation in April 2019 for
$3,469,550. Change order I for $14,610.28 for various changes outside the scope of the
project was approved in January 2021 bringing the new contract amount to
$3,484, 160.28. This change order is for additional electrical work needed at Newton
Pump Station for $27,235.18 with a new contract total of $3,511,395.46.
Change Order 2 is for additional trenching, conduit and wire associated with a new tie-in
to 3-phase power at a new pole installed by Eversource at Newton Drive Pump Station.
This new pole location is approximately 300 feet further from the original pole location.
Although Eversource did evaluate the available power during the design phase, they did
not inform us that the power was not correct at the existing nearby power pole. The cost
for DeFelice Corporation to trench, install conduit and wire from the new power pole
location comes to $27,235.18.
