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.

Change Order #5 to contract with Northeast Earth Mechanics, Inc.

To approve Change Order #5 to the contract with Northeast Earth Mechanics, Inc.
(NEM) in the amount of $83,392 to continue construction of the residential
setback barrier wall in the Phase II landfill. Funding will be through Department:
168 Solid Waste; Fund: Bond; Activity: Soil Wall.

NHDES Solid Waste Rules prohibit placement of municipal solid waste within
506 feet of a residential structure. The Four Hills lined expansion landfill (Phase
I & Il) was designed and constructed with the footprint of the landfill encroaching
the 500-foot setback limit to residences on Farmwood Drive to the west and
Pioneer Drive to the east. In order to comply with the residential setback rule, a
barrier must be constructed within the footprint of the landfill to prevent waste
from being placed in the setback. The barrier wall must be expanded continually
as waste elevations in the landfill increase.

In May 2014 the City solicited bids for construction of Phase 1 of the soil wall
under IFB0593-050514. Six contractors submitted bids for the project with
Northeast Earth Mechanics (NEM) being the lowest bidder:

Vendor Bid results
Northeast Earth Mechanics $163,727.50
Morello Construction $167,337.50
Daniel T. Ladd Site Work $203,300.00
Project Resource Group LLC $234,054.06
Greene & Russell, Inc. $266,000.00
SCS Field Services $297,405.00

Under the original contract in the amount of $163,727.50 Northeast Earth
Mechanics (NEM) began initial construction in July 2014 of the western
residential setback barrier wall in the Phase [/Stage I landfill. Per the NHDES
approved scope of work and contract executed June 10, 2014, NEM established a
compacted soil foundation over the primary liner drainage sand and placed four
lifts of concrete waste blocks on the foundation.

Change Order #1 in the amount of $163,912 provided for the continued
construction of the western wall to an elevation of 260 feet in the Phase Il/Stage |
landfill.

Change Order #2 in the amount of $164,340 continued construction of the
western wail into the Phase [/Stage [I] landfill up to an elevation of 266 feet.

Change Order #3 in the amount of $291,932 allowed for initial construction of
the eastern setback barrier wall, and continued construction of the western setback
wall to an elevation 268 feet. To construct the eastern setback wall, NEM
established the compacted soil foundation over the primary liner drainage sand
and placed concrete waste blocks on the foundation up to elevation 258 feet.

Change Order #4 in the amount of $199,763 continued construction of the
western setback wall from elevation 268 feet to elevation 276 feet. The change
order also included the purchase of 250 extra blocks to be used in the next phase
of wall construction.

Change Order #5 in the amount of $83,392 continues construction of the eastern
setback wail from the existing elevation of 258 feet to elevation 276 feet. The
height increase is needed to keep pace with waste filling activities in the Phase I!
landfill. This phase of wall construction will utilize the extra 250 concrete blocks
purchased under Change Order #4.

It is the recommendation of the Solid Waste Superintendent tc continue
construction of the Set Back Barrier Wall with NEM. They have provided
reasonable, consistent pricing and quality construction services for each
completed phase of this project. Upon approval of Change Order #5 the total
cost of the contract is $1,067,066.
