2016 Sewer Rehabilitation Project

To approve the award of the construction contract for the 2016 Sewer Project to Park
Construction Corporation of Fitzwilliam, NH in the amount of $1,108,975. Funding
will be through: Department: 169 Wastewater; Fund: Wastewater; Activity: Sewer
Rehab, and Department: 169 Wastewater; Fund: Wastewater; Activity: Sewer
Structures.

The annual sewer program addresses failing, aged sewers. This 2016 Sewer Project
is expected to replace or line approximately 2,360 feet of sewer mains. The contract
includes work in the following areas:

Tolles St from Whitney St to Canal St,

Kinsley St approaching Main St,

Lock St between Perham St and Chandler St and

The old residential neighborhood off of Temple St including Hoyts Ln, Scripture St,
Gorman Ave, Worcester St, Shedds Ave and Howard St.

Contract work includes replacing sewer service lateral connections as well as catch
basins and manholes prior to road restoration. Four contractors attended the
mandatory pre-bid meeting on February 24, 2016. Three bids were received on
March 10 as follows:

Park Construction Corporation of Fitzwilliam, NH $1,058,975.00
DeFelice Corporation of Dracut, MA $1,441,347.00
Cardillo & Son, Inc of Wakefield, MA $1,700,591.40

The low bid was reviewed and found to be acceptable. Park Construction
Corporation has performed satisfactorily on other sewer projects of this scale in the
city. Work is expected to begin in April and finish before the end of this year.

Several of the neighborhood streets are very narrow and many underground conflicts
are expected. Therefore, a contingency of $50,000 or approximately 5% is included
in this award to be used on an as needed basis for unforeseen circumstances.

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.

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.
