Re: Headworks Upgrade Project
C. Motion: To award the Headworks Upgrades contract in the amount of $2,848,222 to TBuck
Construction of Turner, ME. Funding will be through: Department: 169 Wastewater;
Fund: SRF Loan; Activity: Headworks Upgrades.
Atiachments: TBuck’s Bid
Discussion: The headworks facility at the wastewater facility removes inorganic material in the
entering wastewater before it enters downstream processes. It was last upgraded in
1999. The equipment is at the end of it useful life due to the corrosive environment and
constant use. The existing layout consists of an intermediate floor where collected
debris has to be transported to the upper (ground) level using heavy minor carts and
overhead hoist making this operation cumbersome, labor intensive and risky.
In January 2015, the City hired consultant Wright Pierce to being the design work. The
various components of this project include new stainless steel screens and rake arms
long enough to remove entering debris from the lower level to the ground floor, wash
presses, odor conirol system, overhead mechanical hoist, relocation of hallway and
women’s locker room to allow room for the screens at pround level, installation of a
new women’s locker room and upgrades to the effluent flow metering vaults.
A total of 8 contractors bid on this project. The following is a summary of the various
contractors and their bids, received on March 2, 2016:
Contractor Bid Amount
T Buck Construction $2,848,222
Penta Corporation $2,851,700
Winston Builders $3,020,889
D&C Construction $3,046,250
Kinsmen Corporation $3,246,000
Waterline Industries $3,297,677
Kingsbury Companies $3,546, 156.68
The bid of the low bidder, T Buck Construction, was carefully checked. In addition,
the references of T Buck were carefully checked and found to be favorable. They have
also completed the Dewatering and Grit Systems Upgrades project at the Wastewater
Facility in 2014 and these upgrades have been working satisfactorily since installed.
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.
