2018 Paving Program — Newport Contract
Change Order No. 3
To approve Change Order No. 3 to the paving contract for the FY18 Paving
Program to Newport Construction of Nashua, NH in the amount of $209,180.
Funding will be through Department 160 Admin/Engineering; Fund: Bond;
Activity: Paving.
The 2018 Paving Contract with Newport Construction to pave approximately 25
miles of streets was amended twice to add more flagging hours, increase flagger
rates and increase the allowance for liquid asphalt adjustment and for changes to
the work done on some streets. With Change Orders 1 and 2, the current total
contract value is $7,137,572.
As work has progressed on the 2018 City Paving Program, more changes have
been made. In some cases, the pavement rehabilitation specification has been
revised on particular streets because of conditions encountered. In other cases,
some streets with immediate needs have been added to the program.
These types of changes were anticipated from the program’s inception. It has
been understood that some streets might be deferred to 2019 in order to allow
such changes to be made within the contract budget.
To the extent that changes have been made to date, other streets have been
deferred. In each case where a street was deferred, there is a justification for the
deferral. This justification is typically based on incomplete utility work on the
street.
However, as work had advanced, an increase is needed to the contract budget to
cover an adjustment based on the continuing increase in cost of Asphalt Cement
($457.50 per ton on 2/1/2018; $550.00 per ton on 10/1/2018). The basis for this
adjustment is specified by New Hampshire Department of Transportation and is
required by contract. This includes $120,000 for the current projection of this
adjustment.
Also, as work has advanced there have been a number of instances when the
milled surface has been found to have significantly more defects than anticipated.
