Subject: Proposal — Addendum
2018 Asphalt Testing Services
2018 Pavement Management Project
Nashua, New Hampshire
Dear Mandeep:
As requested, we have prepared this Proposal to amend our 2018 Asphalt Testing
contract. We understand the City is paving Amherst Street (Route 101A), Somerset
Parkway, Broad Street (Route 130) and Kinsley Street (Route 111) as a part of a
NHDOT and Federal Highway funded program. We understand the project includes the
placement of approximately 30,000 tons of hot mix asphalt.
SCOPE OF SERVICES: S. W. Cole Engineering, Inc. (S.W.COLE) will provide services
as coordinated and directed by the City of Nashua. The original scope of our services,
in response to IFB0660-052418, required the HMA testing to be sampled by the
contractor in the field and the samples provided to us for testing in our laboratory. We
understand the City is requesting us to perform sampling and testing of the HMA at the
suppliers production plant. This allows the technician to observe the HMA batching
process and monitor the portions of materials in the HMA mixture. Additionally we
understand the city is requesting a S.W.COLE to addend a pre-paving meeting and
provide personnel to review the contractors quality control program and mix designs.
We understand that our scope of services includes a HMA Plant Technician to perform
the following services:
