CONTRACTOR: SUR Construction West, Inc.

You are directed to make the following changes in the Contract Documents:
Description:
Recent video of the existing sewer pipes on Water St, Amherst St and Main St shows them to be in
very poor condition. Sik holes have already developed on Main St and Amherst St.
The City Engineering Department would like to have the existing sewer pipes on Water St replaced
between Mechanic St and Factory St. Some existing water pipe owned by Pennichuck Water Works
will also need relocation to allow for the sewer pipe replacement.
Additionally, video has also shown a partial collapse of a 12” sewer pipe on Amherst St at Vernon St.
Replacement of this pipe will be necessary toward Beacon St.
And finally, video has shown a partial collapse of a 12” sewer pipe on Main St between Hollis St and
Mulberry St. CIPP lining of this pipe is questionable which necessitates its replacement including
Jateral pipes to catch basins.
Road restoration of trenches will include three foot overcuts with 18” of gravel base and 5” of asphalt
on Water St and 7” of asphalt on Amherst St and Main St.
Justification:
Failing sewer pipes were discovered on Water St, Amherst St and Main St after this contract was bid.
Waiting to perform this pipe replacement risks loss of sewer service and collapse of the road above the
pipe. SUR West was contracted under IFB0779-021220 to perform the City’s 2020 sewer work and is
actively working in Nashua.
