Re: Energy Recovery Upgrades — Construction Phase Services
C. Motion: To approve the contract with Waldron Engineering of Exeter, NH in an amount
not to exceed $76,762 for construction administration services for the Energy
Recovery Upgrade Project. Funding will be through: Department: 169-
Wastewater; Fund: Wastewater; Activity: Energy Recovery Upgrades.
Attachments: Waldron Engineering Contract
Discussion: The Nashua Wastewater Treatment Facility is undergoing an upgrade of its
energy recovery system.
Waldron Engineering is the design engineer and is very familiar with this project.
The project went out bid in August and 2 bids were received on September 6,
2018. The construction portion of this project is being awarded and construction
phase services from Waldron are needed.
Construction is estimated to last 8 months and Waldron’s services include
residential engineering and construction administration. Their cost proposal for
$76,762 is very reasonable when compared to the overall $1.78 million
construction costs. Typical construction phase service costs are around 8 to 10%
of construction costs, while this is only 5%.
