Re: Change Order Request
Construction Quality Assurance Services - Phase III
City of Nashua Four Hills Landfill
Nashua, New Hampshire
Dear Jeff:
Sanborn, Head & Associates, Inc. (Sanborn Head} appreciates the opportunity to be of
continued service to the City of Nashua (City). As we recently discussed, based on the
additional requirements imparted by the New Hampshire Department of Environmental
Services (NHDES) on the Phase III construction project and the associated construction
delays, we will exceed the approved budget for the Phase III Construction Quality Assurance
Services project. This letter presents our request for a change to our budget.
Background
Sanborn Head's original scope of services, described in our proposal dated February 18,
2019, included the following three (3) tasks:
a CQA Services;
m Construction Meetings/Documentation; and
a CQA Report.
However, during construction our scope evolved to include components that were not
anticipated at the time the existing budget was established. In addition, the total length of
the project was increased due to construction and permitting delays. Our original proposal
assumed that construction would take approximately 16 weeks, and as of the date of this
letter, the Phase III construction project is currently in its 26% week of construction. The
additional time and requests for services require a change to our approved budget.
Additional Services Already Provided
Since submitting the February 2019 proposal, several requests were made that were outside
our Construction Quality Assurance Services agreement. Below is a list of the major
differences that were not reflected in our proposal:
a Preparing narratives, figures, and tables associated with the Groundwater
Demonstration required by Condition 6 of the Phase III] permit, dated December 5, 2018;
