Title
108th & 159th Manhole Rehabilitation Emergency Repair - Proposal
History
While performing inspections on 159th Street and 108th Avenue as part of the ongoing 159th Street Improvement Project, staff found that the Spring Creek Lift Station force main discharge manhole had major deterioration due to the degrading effects of hydrogen sulfide gas. The structure is in the southbound lane of 108th Avenue at 159th Street. The area is currently under construction pending placement of the concrete pavement. To prevent failure, it is recommended to install a fiberglass liner in the structure. It was also recommended that the downstream manhole be sprayed with an epoxy coating as a preventive measure. This downstream manhole is newly installed as part of the force main relocation.
Multiple products and numerous application techniques are available. Utility Division staff met with two companies and determined that the discharge manhole would require the fiberglass liner, whereas a hand-sprayed epoxy would be the best solution on the adjacent manhole.
Two companies were requested to submit proposals for this work. National Power Rodding Corp. of Chicago, Illinois, submitted a proposal totaling $30,000.00 for one structure liner. National Power Rodding has previously performed similar work for the Village. Airy’s Inc. of Tinley Park, Illinois submitted a proposal for one fiberglass manhole liner at a cost of $14,277.00 and epoxy coating for the adjacent structure for $4,585.00. Therefore, staff recommends accepting the proposal from Airy’s Inc. of Tinley Park, Illinois for the rehabilitation of two manholes for a cost totaling $18,862.00. Based on severity of deterioration to the manholes and the impact to the logistics of the 159th Street Improvement Project this work was coordinated for immediate repair.
On November 7, 2016, this item was reviewed by the Public Works Committee and recommended for approval and referred to the Village Board of Trustees for c...
