Attached for your review and consideration for approval is a deductive change order in the amount of  ($25,991.00) and the final pay request in the amount of $45,483.50 from Layne Inliner, LLC for sanitary sewer gravity main rehabilitation project completion. 

As Council is aware, this type of project has been included annually in the Public Works Capital Improvement Program as a continual proactive approach to rehabilitate an aging infrastructure.  This type of rehabilitation method has a considerable reduction in cost from traditional pipe laying construction because it eliminates the cost of restoration and allows the existing facilities to remain in place with no disruptions to the general public.

The areas included in this project were the East Madison, North Park and North River Neighborhoods, Glengarry, Magnolia Valley, the Meadows Subdivisions, Brandywine Condominiums, the Downtown area, and the US Hwy 19 Corridor.  All of the gravity mains lined contained extensive cracking that resulted in infiltration of water, sand, and root intrusion.  These pipe conditions, if left uncorrected would continue to result in higher sewer lift station pump run times which increase the utilities operating and maintenance cost for equipment repair and treatment of effluent.
