A. Motion: To approve Change Order #6 to the contract with Northeast Earth Mechanics, Inc.

Discussion:

(NEM) to continue construction of the residential setback barrier wall in the Phase

Tk Landfill in the amount of 765%. Funding will be through Department: 168
Solid Waste; Fund: Bond;{Activity: Soil Wall.
SIGN, GES

NHDES Solid Waste Rules prohibit placement of municipal solid waste within
500 feet of a residential structure. The Four Hills lined expansion landfill (Phase
I & II) 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 $234,054.00
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 W/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 IVStage I
landfill.
