City of Nashua, Public Works Division
Board of Public Works Meeting Date: April 26, 2018
Stephen Dookran, P.E., City Engineer
Engineering Department
2018 CIPP Lining
Construction
To approve the construction contract for the 2018 CIPP Lining to Layne Inliner of
Fairfield, ME in the amount of $715,657.50. Funding will be through: Department: 169
Wastewater; Fund: Bond; Activity: Sewer Rehab.
The annual sewer program addresses failing, aged sewers and associated structures and
piping. This 2018 Cured in Place Pipe (CIPP) Lining project is expected to line
approximately 6,200 feet of sewer mains, of which about 5,700 are under roadway and
530 feet are off road. In general, the connecting drainage basins and drainage pipes will
be excavated and replaced under a separate contract. The locations of CIPP Lining
included in this contract are:
Kinsley St - Walnut St to Vine St and from Ritter St to Woodward St
Lake St from Pine St to 254 Lake St (near Caldwell Rd)
Gillis St from 4 Gillis St to Arlington Ave
Manchester St from 17 Manchester St to Hopkins St
Liberty Utilities yard area at 38 Bridge St
Five contractors attended the mandatory pre-bid meeting on March 28. Two bids were
received on April 17 as follows:
Insituform Technologies of Chesterfield, MO $748,705.00
Layne Inliner of Fairfield, ME $715,657.50
The low bid was reviewed and found to be acceptable. Although Layne Inliner has not
previously worked for the City, we have checked their references and found them to be
acceptable.
General coordination issues may impact the construction schedule. For example,
certain parts of the 2018 Sewer Replacement contract need to be done ahead of this
contract. Therefore, this contract may run into a second construction season.
