In many cases, the existing pavement was thinner than anticipated and the entire
thickness was milled off leaving areas of exposed gravel. It had been intended
that an average %4-inch shim would be placed on the milled surface prior to
placement of the wearing course. In practice, a greater amount has been placed
for this shim course largely because of the defects and unexpectedly thin
pavements encountered. This Change Order also includes $80,000 to cover the
anticipated total of this increased shim quantity.

Finally, it has been determined that Kehoe Avenue, which was specified to be
milled and overlaid, should be reclaimed. Without any more streets in the
program which can be deferred, an additional $9,180 is included in this change
order to cover the increased cost for Kehoe Avenue.

SUMMARY:

Asphalt Adjustment $120,000
Additional Shim Pavement $ 80,000
Kehoe Avenue $ 9,180
TOTAL $208,186

With Change Order #3, the total value of the contract is $7,346,752.

2018 Federal Paving Program — Amherst St. (Rt. 101A), Somerset Parkway, Broad St. (Rt.
130) and Kinsley St (Rt. 111)

To approve the Change Order No. | to the paving contract for the 2018 Federal Paving
Program to Newport Construction Corp. of Nashua, NH in the amount of $611,545.18.
Funding will be through: Department: 160 Admin/Engineering; Funds: Grant and Bond;
Activity: NHDOT Nashua Roadway Improvements and Paving.

The 2018 Federal Paving contract in the amount of $3,987,518.90 was awarded to
Newport Construction of Nashua in September 2018 to pave Somerset parkway and
portions of Amherst St, Broad St and Kinsley St. Work is underway on Somerset
Parkway and Amherst St.

A recent projection of the amount of work remaining in the contract revealed that the total
quantities for the bid items were missing all the quantities for Somerset Parkway. This
computational error occurred during the time we were going back and forth with the
NHBOT on whether the project was to be bid as individual contracts for each street or as
one large contact.

In the end, Federal Highway (FHWA) would approve only the one large contract and in
re-compiling the quantities, the items for Somerset Parkway were inadvertently excluded.
The bid we received and contracted on was much lower than expected because of the
oversight. Without the error, the original contract would have included the quantities for
Somerset Parkway at the correct contract price.

Newport has agreed to hold their bid unit prices for the additional quantities which amount
to a total change order of $611,547.75. If this additional work is included for the other
bidders, Newport is still the lowest bidder and the new contract amount will be
$4,599,066.65. Since FHWA is funding $4.445 mil, the remaining $149,066.65 will come
from City paving funds.

This change order includes an extension of time in order to complete the entire project and
will be subject to approval by NHDOT and FHWA.
