2018 CIPP Lining
Change Order No. 2
To approve Change Order No. 2 to the construction contract for the 2018 CIPP Lining
with Layne Inliner of Fairfield, ME in the amount of $50,995. Funding will be through:
Department: 169 Wastewater; Fund: Wastewater; Activity: Sewer Rehab.
Layne Inliner was awarded the contract to line approximately 6,200 feet of sewer in
April 2018 with a contract value of $715,657.50. In July, Change Order No. 1 was
approved to accommodate lining related work on additional streets, bringing the total
value of the contract to $835,657.50.
Engineering coordinates construction projects with Liberty Utilities and Pennichuck
Water Works. In Lock St from Cross St to Salem St, both utilities are replacing old
infrastructure. A new gas line will be constructed a few feet over a 36 inch cement
combined sewer pipe constructed in 1935. Video inspection of the sewer indicates the
sewer to be deteriorating as is typical of a sewer pipe of this material and age and would
be recommended for rehabilitation. This change order is to line 310 feet of the sewer
from manhole to manhole to ensure the pipe is not compromised during the installation
of the gas line.
With this Change Order No. 2, the total value of the contract is $886,652.50
