City of Nashua, Public Works Division
Board of Public Works Meeting Date: May 18, 2017
Noelle Osborne, Plant Operations Supervisor
Wastewater Department
Headworks Upgrade Project
To approve the change order to the Headworks Upgrades contract with T-Buck
Construction, Inc. in the amount of $27,625.06 Funding will be through: Department:
169 Wastewater; Fund: SRF Loan; Activity: Headworks Upgrades.
Change Order 4 Backup
The contract with TBuck for the Headworks Upgrades at the Wastewater Treatment
Facility is currently for $2,911,717.05, which includes all change orders to date.
This current change order is for 3 items. The first item is modifications of a vent duct to
accommodate a new HVAC project. The second is the relocation of a previously
unknown duct that was discovered during the men’s locker room expansion. The third
includes the relocation of power ducts in the ceiling that are within the floor space of
the new screenings room. The new screenings room will be a sealed room with its own
ventilation system to meet the requirements of a classified space. The overhead
conduits therefore have to be relocated to allow this classification. All of this work has
been reviewed and approved by the consultant Wright Pierce.
The total amount of this change order comes to $27,625.06. Wright Pierce and the
Wastewater Department have reviewed these costs and it appears to be in line with the
work to be done. The new value of their contract following this change order will be in
the amount of $2,939,342.11.
This project is an SRF funded project and the City will be seeking a State Aid Grant
(SAG) in the amount of 20% of the costs should such funding become available.
