SUBJECT:
Resolution authorizing the Director of Purchasing to execute Change Order Request Number 1 to the Contract with Hoerr Construction Inc. for the 2024 Sanitary Sewer CIPP Lining project in the amount of $84,825.00.
PURPOSE:
To rehabilitate an existing brick storm sewer on E. Galena Boulevard using the spray in place pipe lining method. Lining of this storm sewer would prevent future pipe failures that would likely result in much costlier dig repairs or property damage.
BACKGROUND:
In early November, the City had a contractor lined up to repair the brick crosswalk on E. Galena Boulevard at the Water Street mall pedestrian crossing just east of the Fox River due to settlement of the crosswalk. During the removal process, a massive void was discovered under the brick crosswalk. This void was caused by a 2'x2' failure in the brick storm sewer pipe approximately 12' deep.
E. Galena Boulevard was immediately closed to traffic and an emergency repair was performed over the next several days. While this repair addressed the immediate area of the failure, additional rehabilitation is desired to address the rest of the pipe and reinforce the repair made. The City contacted the contractor that completed the 2024 cured in place pipe lining contract which was Hoerr Construction Inc. Hoerr Construction recently provided an estimate to perform spray in place pipe lining on the brick pipe when the weather is above freezing for a few days. The Spray in Place pipe lining method is proposed in lieu of the cured in place pipe lining method because the brick storm sewer is not circular but rectangular with an arched top. The engineering division believes the $84,825.00 Hoerr proposal to be a fair price due to the size/shape of the pipe and the limited access to the pipe ends.
The engineering division is planning on bidding the 2025 CIPP sewer lining contract l...
