2019 CIPP Lining Project
Change Order #2

To approve Change Order #2 for the 2019 CIPP Lining Project with Kenyon Pipeline
Inspection of Queensbury, NY for an amount not to exceed $1,500,000. Funding will
be through Department: 169 Wastewater; Fund: Bond; Activity: Sewer Infrastructure
Improvements.

2019 CIPP Lining Project Change Order #2

Kenyon Pipeline Inspection was the low bidder of the 2019 CIPP Lining Project and we
have found their work to be satisfactory. A previous Change Order 1 was approved
(no-cost change order). The purpose of this Change Order #2 is to provide additional
funding for lining of deteriorated sewer pipes, as identified through previous video
inspection, and to complete cleaning, video inspection, and lining of additional sewer
pipes throughout the City.

Over the course of the existing contract with Kenyon and though our other video
inspection work on our aging and deteriorating sewer system, the need for additional
inspection and lining has been identified. Over 10,000 linear feet of pipe has been
identified as needing lining and we expect additional priority needs will be identified
through continued pipe assessment. The Engineering Department would like to continue
to use the services of Kenyon and seeks a $1.5M change order to continue to clean,
video inspect, and line deteriorated sewer pipes throughout the City. Keyon has agreed
to hold their original bid prices for this change order.

Assessing sewer pipes enables us to identify pipes in need of repair and address them
before they deteriorate to the point of needing complete replacement, which is
significantly more expensive and disruptive to the public. Pipe lining is substantially
less expensive than pipe replacement, and is the most economical option for sewer pipe
rehabilitation.

OWNER’S CONTRACT NO: IFB1087-021219
EXECUTED CONTRACT DATE: 04/19/19
DATE OF ISSUANCE: 04/13/20 EFFECTIVE DATE: Upon City Approval
OWNER: City of Nashua, NH
OWNER’s Purchase Order NO..: 148060
CONTRACTOR: Kenyon Pipeline Inspection, LLC
ENGINEER: DPW Engineering

You are directed to make the following changes in the Contract Documents:

Description:

The additional video provided by Kenyon through Change Order | has revealed more crumbling sewer pipes
throughout the City. Most of these pipes are still intact enough to enable them to be lined with an epoxy-infused
feit liner, providing many more years of service life. The Division of Public Works Engineering Department
would like to continue to utilize Kenyon’s services to clean, video inspect, and line sewer pipes throughout
Nashua by extending the existing contract under this Change Order 2.

Justification:

In order to prevent existing sewer infrastructure from deteriorating to the point that it needs complete
replacement, the Division of Public Works Engineering Department proposes to extend Kenyon’s existing 2019
CIPP Lining Contract into 2020 by awarding a $1.5M change order to clean, video inspect, and line additional
sewer pipe throughout the City.
