City of Nashua, Public Works Division
Board of Public Works Meeting Date: January 26, 2017
Noelle Osbome, 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 $47,438.05. Funding will be through: Department:
169 Wastewater; Fund: SRF Loan; Activity: Headworks Upgrades.
Change Order 2 Backup
The contract with TBuck for the Headworks Upgrades at the Wastewater Treatment
Facility is for $2,848,222. Change order 1 in the amount of $8,460.75 was for the
installation of a 6” insertion valve on the 6” protected waterline.
This change order is for a number of items as shown in the attached backup material
including new lockers for the men’s locker room, making the new women’s locker
room ADA compliant, relocating pipes and ducts due to conflicts, replacing a waterline
valve that does not work, and changing out the electric circuit for a new heater. These
additions were not known during the design phase since some pipes, particularly drain
pipes are often concealed behind wall and the conflict was not known till the contractor
began removing walls according to the plans.
The total amount of this change order comes to $47,438.05. The Engineer (Wright
Pierce) and Wastewater Department has reviewed these costs and appear to be in line
with work to be done. The new value of their contract following this change order will
be in the amount of $2,904,120.80.
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.
