SECTION 4: SCOPE OF WORK

The Oakland County Water Resources Commissioner’s office (WRC) is responsible for the operation and maintenance of 40-mil, HDPE membrane liners located at 1480 W. Romeo Rd, Leonard MI. The liners are currently installed in the wastewater treatment lagoons located at Addison Oaks Oakland County Park.

WRC is seeking vendors to provide as-needed repair services on 40-mil HDPE membrane liners.

Lagoon Liner Repair The vendor shall perform a pre-installation inspection of the existing liner to adequately verify any and all existing conditions required to repair the 40-mil HDPE membrane lagoon liners. Vendors shall have ability to test the tensile strength of the liner repair. Technicians utilizing the tensile must have a minimum of 2 million square feet of welding experience.

If dewatering was necessary to perform repair, Oakland County will perform dewatering.

The vendor shall furnish all material and labor for the repair of the membrane liner in accordance with all applicable manufacturer’s requirements. If any connections and/or anchor trenches must be replaced or repaired, they must be in accordance with the liner manufacturer’s recommendations. The vendor must submit a quote for approval, with the appropriate WRC staff, outlining the repairs, the timeline for repairs, and any material/equipment fees.

If sections of lining must be removed, the removal of the existing liner material must be disposed of off-site and in accordance with all Federal, State, and Local requirements. All repairs shall be done without disrupting subgrade materials and any intake/discharge piping or other liner penetrations from damage. Any such damage shall be corrected by the vendor prior to placement of the new liner material.

Any backfilling shall be carried out in a planned, logical sequence to not overstress the liner. All grassed areas disturbed by repair work shall be fine-graded, seeded, and mulched to restore vegetation.

Vendor shall make corrections regarding inferior or incomplete work or materials furnished, without additional compensation, if it is determined that the vendor is responsible for any errors or deficiencies. A minimum of one year warranty period shall apply on all repairs and materials.

Work shall be performed in a manner that protects the integrity of the existing liner material and protect the uncontrolled release of the lagoon’s contents onto the ground surface.

If the vendor encounters work required beyond this Scope of Work, a description and estimated cost shall be submitted for review and approval. Approval from appropriate staff will be required before completing any additional work.
