2018 Sewer Replacement ~- Harvard St
Change Order 2

To approve Change Order No. 2 to the construction contract for the 2018 Sewer
Replacement — Harvard St project to Northeast Earth Mechanics of Pittsfield, NH in
an amount of $440,037.10. Funding will be through: Department: 169 Wastewater;
Fund: Bond; Activity: Sewer Rehab.

The original contract to Northeast Earth Mechanics in the amount of $692, 905.20
was for the replacement of the 1887 cement sewer main on that street Harvard St.
This work has not started because Pennichuck must replace the water line prior to
construction beginning.

In the meantime, the 15 inch cement sewer constructed in 1885 in Chase Street has failed
and requires immediate replacement. In addition, one property on the street is experiencing a
sewer backup. Through a no cost Change Order No. 1, Northeast Earth Mechanics was
directed to use the existing contract funds to replace the sewer on Chase St.

The purpose of this Change Order No. 2 is to replenish the funds so that the Harvard St.
sewer can be constructed in the spring. The value of the Chase St work is $440,037.10.
Pending bond approval to provide these funds, this Change Order No. 2 is to replenish
the $440,037.10 for Harvard St.

Upon approval of Change Order 2, the total value of this contract will be $1,132,932.30.
