2018 Paving Program ~ Newport Contract
Change Order No. 2
To approve Change Order No. 2 to the paving contract for the FY18 Paving Program
with Newport Construction of Nashua, NH in the amount of $359,738. Funding will
be through Department 160 Admin/Engineering; Fund: Bond; Activity: Paving.
As the City is paving numerous residential, collector, and arterial streets, the City’s
paving contractor Newport Construction has to furnish 6 io 16 qualified flaggers to
direct traffic through or around the work zones, depending upon the number of side
streets and traffic on the paving street. At any given time, at least three to four
Newport crews are working on different streets. Therefore, Newport has to furnish at
least 8 flaggers on a daily basis. In the bid request, the City carried an allowance of
$100,000 and Change order#1, Engineering requested additional $50,000. Since
construction began in May, Newport has been billed by the flagger company at
elevated rates. Therefore, Engineering is requesting a change order for an additional
$100,000 to Newport’s contract to cover charges associated with increased demand of
flaggers at the paving projects.
Since construction began in May, paving treatment of few of the mill and overlay
streets has been changed to reclaim. Some of the streets where the treatment has
changed are Forest Street, Brickyard Lane, Shelley Drive (Scott Avenue to Keats
Street), sections of Southwood and North Southwood, and White Plains Drive. The
reason for change in treatment has been that these streets had low Pavement Condition
Index (PCD in 2017, but last year’s winter was rough which further caused
deterioration due to freeze and thaw cycle. To address the concern, the treatment
method was changed from mill and overlay to reclaim (10”). Total increase in cost of
reclaim item would be $70,568.
Allowance for liquid asphalt adjustment in the bid request was $70,000. It was based
on the base price of asphalt cement of $457.50 per ton (as of February 1, 2018). The
prices have increased to $540.00 per ton and it is based on the latest price published by
the NHDOT dated July 1, 2018. Therefore, DPW is requesting an increase in
allowance for liquid asphalt adjustment in the amount of $165,000.
A right turning lane will be added to Charron Avenue to address ongoing traffic back-
up issues. Therefore, Engineering is requesting $24,170 to widen the street by about
10 feet for a length of 255 feet.
