BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities issued Bid 17-028 seeking a contractor for the rehabilitation of existing sanitary sewer pipelines by installing glass reinforced plastic cured-in-place thermosetting resin pipe cured with ultraviolet (UV) light. This new process was specified because it is safer, has less impact on the environment and provides a product that is stronger and more flexible than heat Cured-in-Place-Pipelining (CIPP) that the City has historically used. Recently, the City successfully installed UV-cured liners in small-diameter applications. This will be the first large-diameter lining project utilizing this product.

|
Layne Inliner, LLC |

The Engineer’s Estimate for this project was based on an average historic bid unit price of $365 per linear foot for the traditional CIPP lining and budgetary quotes from vendors, plus $14,000 per manhole. Since Naperville has not previously completed any large-diameter lining with UV-Cured CIPP. The Engineer’s project estimate is significantly higher than the low bidder’s project proposal, but in line with the other bidders.
Michels Pipe Services is experienced with installing UV-cured CIPP.
