City of Nashua, Public Works Division
Board of Public Works Meeting Date: March 24, 2016
Dave Simmons, Superintendent
Wastewater Department
Headworks Upgrade Project — Construction Phase Services
To award the contract to Wright Pierce for construction phase services for the Headworks
Upgrade project at the Nashua Wastewater Treatment Plant in an amount not to exceed
$323,300. Funding will be through: Department: 169 Wastewater; Fund: SRF Loan;
Activity: Headworks Upgrades — Engineering Services.
The Nashua Wastewater Treatment Facility (NWTF) headworks facility has exceeded its
useful life and is in need of a complete overhaul. Wright Pierce has completed the design
of the upgrades and has prepared bid plans and specifications. Concurrent with the award
of the construction of this project, the construction management of this project needs to
be awarded. As has been done in the past, the NHDES prefers that the construction phase
services be performed by the design engineer.
The construction phase services will occur for the length of the construction which is
expected to take 12 months. It will involve a full time resident engineer on-site and
extensive engineering support from Wright Pierce’s main office.
Their fee of not-to-exceed $323,000 is approximately 10.4% of the total estimated
construction cost of $3,100,000, and approximately 11.4% of the low bidders. This
percent is typical for this type of plant rehabilitation project.
Wright Pierce provided construction phase services for the Dewater and Grit System
Upgrades project as well as other smaller projects at the Plant. They have provided
quality construction services for these projects.
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.
