RE: Contract No. 2300600
96-Inch Water Transmission Main Relocation - Phase II
Vendor: Ric-Man/Clark Joint Venture
MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2300600, “96-Inch Water Transmission Main Relocation - Phase II” with Ric-Man/Clark Joint Venture, at a cost not to exceed $56,350,500.00 for a duration of 852 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The existing 96-inch Water Transmission Main (WTM) is part of GLWA’s overall drinking water transmission main system that interconnects the Lake Huron Water Treatment Plant (LHWTP) with the Northeast and Springwells Water Treatment Plants (WTPs) through the North Service Center Pumping Station. The existing 96-inch WTM was constructed in the mid-1960s and was placed into service in December 1967. Part of the original construction of the 96-inch WTM was a section within Shelby Township that was installed within the influence of the G&H Industrial Landfill site.
The current relocation project consists of approximately 2.5 miles of 96-inch WTM currently located in the influence of the decommissioned G&H Industrial Landfill site, a listed U.S. Environmental Protection Agency Superfund Site located in Shelby Township, MI. The construction has been sequenced to occur in three phases as follows:
• Phase I referred to as the “Early Works Package - Avon Road Improvements” consisted of 2,200 lineal feet of new 96-inch WTM to be installed along Avon Road in Rochester Hills. Phase I of construction is currently in progress under Contract No. 2004825 and is anticipated to be completed in Mid-August of 2023.
• Phase II scope of work includes installation of 7,985 lineal feet of 96-inch WTM installation along Dequindre Road between Hamlin Road and the Macomb Orchard Trail just north of 23 Mile Road.
• Phase III scope of work will include 2,900 lineal feet of 96-inch WTM installation along the Macomb Orchard Trail between Dequindre Road and 24 Mile Road. Phase III will include system isolation valves, final connections near the Rochester Booster Station and the intersection of Dequindre/Hamlin Road, and the abandonment of existing WTM.
Once all three phases are complete, the relocated 96-inch WTM will be connected to GLWA’s existing WTM system between the North Service Center and Rochester Booster Station. Upon placing the new section of 96-inch WTM into service, the existing WTM within the influence of the inactive G&H Industrial Landfill site will be decommissioned and abandoned in place.
JUSTIFICATION
Contract No. 2300600 is for Phase II of the 96-inch WTM relocation project. This project is considered a priority project under the Michigan Department of Environment, Great Lakes, and Energy (EGLE) Drinking Water State Revolving Fund (DWSRF). In order to maintain the EGLE funding fiscal year loan schedule and priority status, approval of Contract No. 2300600 is required. The continuation of the 96-inch WTM relocation project is essential in providing improved access for future operations and maintenance of the 96-inch WTM. In addition, it will increase resiliency of the water transmission main system with the installation of isolation valves allowing for operational flexibility and redundancy in the future.
