City of Nashua, Public Works Division
Board of Public Works Meeting Date: February 25, 2021
Jeff Lafleur, Superintendent
Solid Waste Department
Change Order #1 - Landfill Engineering Services Contract
To approve Change Order #1 to the engineering services contract for the City of
Nashua’s active and closed landfills with Sanborn Head and Associates of
Concord, NH in the amount of $31,000.00 Funding will be through: Department:
168 Solid Waste; Fund: Solid Waste; Account Classification: 53 Professional and
Technical Services.
Sanborn Head and Associates updated scope of services
Sanborn Head and Associates (SHA) is the City’s primary engineering consultant
for landfill and solid waste related issues, including landfill gas management,
design and construction; groundwater, air and solid waste permitting; capacity
analyses; regulatory representation; and general landfill operations. They review
and prepare documents required by the City’s Title V air emission permit. They
also prepare the annual Greenhouse Gas Emissions report that is required by the
USEPA.
This year the Solid Waste Department has required more engineering services
than a typical year. All of the City of Nashua landfill site groundwater
management permits need to be renewed as well as the Four Hills Landfill Title V
Air Permit including updating our air dispersion model to include the Phase II
area. Because of this extra work that must be completed for NHDES, Sanborn
Head has provided an updated scope of services for the rest of FY21. As a result
Solid Waste Department will need an additional $31,000.00 to pay for the
remaining work to be completed.
As such, they have a thorough understanding of the issues and requirements of the
Four Hills facility and other closed City landfills, and provide consistent, high
quality engineering and consulting services to the department in a timely manner.
They have demonstrated superior abilities relative to regulatory reporting,
permitting, design and construction oversight. Therefore, they are considered a
sole source for these services.
Sanborn Head has provided the required certificate of insurance to accomplish
these services.
