2018 Asphalt Testing — S.W. Cole
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.
