2019 CIPP Lining Project
Change Order No. 5

To approve Change Order No. 5 for the 2019 CIPP Lining Project with Kenyon Pipeline
Inspection of Queensbury, NY in the amount of $200,000. Funding will be through
Department: 169 Wastewater; Fund: Wastewater; Activity: Stormwater Abatement.

Kenyon Pipeline Inspection was the low bidder of the 2019 CIPP Lining Project and has
performed well over the course of the contract completing CCTV inspection and lining
of both sewer and drain pipes. Four previous change orders have been approved to extend
their services.

The Engineering Department would like to continue to use the services of Kenyon to
identify pipes that need rehabilitation until the contractor for the 2021 CIPP Lining
contract can begin work in early June. CCTV inspection of sewers in roads proposed to
be paved in the Paving Program would be included in this work. Deteriorated sewers may
also be lined under this change order, as needed.

With this change order, the amended contract value will be $4,849,635.

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

Description:

Kenyon Pipeline Inspection has continued to provide video and pipe lining services to the City into 2021. The
funds in the contract and subsequent change orders have been nearly exhausted but the need for these services
continues to exist. A change order is appropriate until the winner of the 2021 lining and inspection contract can
begin work around June 1, 2021.

A new pay item #13 will need to be established to pay for work previously not identified. Item 13—CCTV
Video Inspection of Catch Basin Laterals Pipe sizes 6” to 12” Including Light Cleaning and Root Cutting will be
paid at $5.00 per linear foot.

Justification:

In order to continue to identify and line ageing sewer pipes, the Division of Public Works Engineering
Department proposes to extend Kenyon’s existing 2019 CIPP Lining Contract further into 2021 by awarding a
$200,000 Change Order. This is a stop-gap change order until Green Mountain Pipeline Services can begin work
on their 2021 contract around June 1, 2021.

preventative maintenance, including updating costs and decision trees for selecting
prioritized lists of roadways to pave. This request is for $31,600 to fund the third

to use Cartegraph’s pavement condition assessment software while evaluating
approximately 101 miles of roadway, and updating the Pavement Condition Index
