2018 Sewer Replacement — Harvard St (and Chase St)
Change Order 3
To approve Change Order No. 3 to the constructicn contract for the 2018 Sewer
Replacement — Harvard St project to Northeast Earth Mechanics of Pittsfield, NH in
an amount of $150,000. Funding will be through: Department: 169 Wastewater;
Fund: Wastewater; Activity: Bond; Activity: Sewer Infrastructure Improvements.
The original contract to Northeast Earth Mechanics was for the replacement of the
1887 cement sewer pipe on Harvard St but when the 1885 sewer on chase St suddenly
failed, the replacement of that pipe was added to the contract by previous change
orders. The current contract value is $1,132,932.30.
All of the underground pipe work on Chase St was completed over the winter.
However, because of the sewer being very deep and the street being very narrow, the
road and sidewalk had to be completely removed to access the sewer. The cost of
rebuilding the street and sidewalk is not in the current contract and needs to be added
by change order. This Change Order, #3 wil! add funds needed to reconstruct the
road and sidewalk.
Upon approval of Change Order 3, the total value of this contract will be $1,282,932.30.
