Title
9775 West 143rd Street - Sanitary Sewer Repair - Board Approval
History
In preparation for the 143rd Street and LaGrange Road Improvement Project, the sanitary service laterals for each building along 143rd Street were inspected for elevation conflicts and integrity. Each service was televised to check its condition and to proactively determine if repairs were needed to avoid future work within the new roadway. One service required replacement and three can be repaired with other methods currently being explored.
The service requiring replacement located at 9755 West 143rd Street was found to be in conflict with the proposed retaining wall. During our investigation, it was also found that two pipes exit the building. One of the pipes was within the Village right-of-way and was completely blocked with roots.
Due to the complexity of the repair (numerous utility crossings and challenging terrain on top of the existing retaining wall), Airy’s, Inc. of Tinley Park, Illinois, was asked to evaluate the job. They have the specialized equipment required to facilitate this challenging time sensitive repair. Therefore, because of these difficulties, it was decided to complete the work on a time and material basis. To minimize costs, Village staff assisted by providing repair materials and trucking for spoil and stone fill. The cost for this work which extended over four days totaled $15,692.
On April 4, 2011, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
Financial Impact
Because this work was being done as a result of the 143rd Street and LaGrange Road Improvement Project, funds from the Capital Improvement Account #054-0000-499.84-80 will be used.
Recommended Action/Motion
I move to approve payment to Airy’s, Inc. of Tinley Park, Illinois, for the replacement of the sanitary sewer at 9775 West 143rd Street in the amount of $15,692.
