Change Order No. i

To approve Change Order No. | to the asphalt testing contract for the 2018 Asphalt
Testing with S.W. Cole of Londonderry, NH in the amount of $27,581. Funding will
be through: Department: 161 Street; Fund: General; Activity: Paving; Department:
161 Street; Fund: Trust; Account Category: 54 Property Services.

As the City is proceeding with paving of four arterial streets (Amherst Street,
Somerset Parkway, Broad Street, and Kinsley Street) using federal funds, additional
funds are needed to test hot mix used during paving operations. Testing will be
performed in accordance with NHDOT sampling and testing specifications. Testing is
being conducted to ensure compliance with contract specifications for compaction,
liquid asphalt content, pavement thickness, and aggregate gradation.

The original contract was advertised on May 10, 2018. A mandatory pre-bid meeting
was held in DPW office on May 15, 2018. The meeting was attended by two vendors
(Greenman-Pedersen, Inc. and S. W. Cole Engineering, Inc.). One bid (S.W. Cole)
was received on May 24, 2018, and they were the lowest qualified bidder. S. W. Cole
was awarded the contract to perform asphalt testing for 2018 Paving Program with a
contract value of $43,875.

This change order, (Change Order No. 1) is for testing for hot-mix on above-
mentioned arterial roads. This testing is required as part of NHDOT requirements and
will cost $27,581. S.W. Cole has satisfactorily performed testing for the City in the
past and the prices are reasonable.

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:

If back-to-back days of plant testing services are not required at the HMA plant due to
the paving schedule, we anticipate that some of the drilled cores will be tested at our
laboratory and billed at the unit rates provided in our response to IFBO660-052418.

The project will be serviced from our Londonderry, New Hampshire office. Our project
manager will be Andrew Michaud and can be reached at 603-716-2111 or
Andrew.Michaud@swcole.com.

SCHEDULE
We anticipate that our services will likely be needed on a part-time, as scheduled basis.
We generally request 48 hours notice for scheduling of our services.

BUDGET AND COMPENSATION
S.W.COLE will charge for our services on a unit rate basis in accordance with
Attachment A. The estimated cost for our services is included in Attachment A-1.

For estimating purposes, we have assumed 60 days of plant testing and observation
services. When the contractor submits a construction schedule, recommend
reevaluating our estimate and make adjustments if necessary.

TERMS AND CONDITIONS
We understand that the City will prepare a formal contract or purchase order should we
be selected for these services.
