Energy Recovery Upgrades Project
To approve the contract with Methuen Construction of Plaistow, NH in the amount not to
exceed $1,787,378 for the construction of upgrades to the Energy Recovery building at
the Wastewater Treatment Facility. Funding will be through Department: 169
Wastewater; Fund: Wastewater, Activity: Energy Recovery Upgrade Project.
Methuen Construction Bid
The Nashua Wastewater Treatment Facility is undergoing an upgrade of its energy
recovery system. This system utilizes methane gas produced from the digester complex to
feed a generator that supplies power to different areas of the Facility as well as supply
power back to the grid. The energy recovery facility was built in 1999. The generator
portion of the facility has failed and is in need of a complete upgrade.
Waldron Engineering was contracted to design the new energy recovery system. Plans
and specs were sent to 6 contractors on August 9 and ihe bid opening was held on
September 6. Two bids were received as follows:
Methuen Construction, Inc. $1,787,378
Engineered Construction Services, Inc. $3,127,796
Methuen Construction bid of $1,787,378 is lower than an independent cost estimate of
$2.2 million. We discussed these costs with Waldron Engineering and determined that
these costs are reasonable. Methuen has indicated they are willing to discuss value
engineering and cost reduction following award of contract. Methuen Construction is
well qualified for this project and has done multiple projects at the wastewater facility in
the past.
