RE: Requisition No. 2401015/REQ-0000333
Design Build for 96-Inch Water Transmission Main
Relocation Phase 3
Vendor: Ric-Man/Clark Joint Venture
Status: New Contract/PO
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 Requisition No. 2401015/REQ-0000333, “Design Build for 96-Inch Water Transmission Main Relocation Phase 3” with Ric-Man/Clark Joint Venture, at a cost not to exceed $138,611,881.17 for a duration of four (4) years; 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, Michigan. The construction has been sequenced to occur in three phases.
• 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 construction was completed under Contract No. 2004825 in December 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. This phase is currently in progress under Contract No. 2300600 and has an anticipated completion date in Fall 2025.
• Phase III scope of work includes 2,900 lineal feet of 96-inch WTM installation along the Macomb Orchard Trail between Dequindre Road and 24 Mile Road including a new isolation valve and vault. Phase III will also include isolation valve at North Service Center (NSC), additional 300 feet of 96-inch WTM installation and final connection at NSC, double line stop installation for connections at Rochester Booster Station, final connections at the intersection of Dequindre/Hamlin Road, backup pumping system at M-59 and Snover Road, temporary discharge facility, existing 96-inch WTM appurtenances replacement, Dorsey Dickinson Valve rehabilitation, and NSC I-Valve Train No. 3 replacement.
Once all three phases are complete, the relocated 96-inch WTM will be connected to GLWA’s existing WTM system between 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 decommissioned G&H Industrial Landfill site will be decommissioned and abandoned in place.
JUSTIFICATION
This Proposed Requisition No. 2401015 is for Phase III of the 96-Inch Water Transmission Main Relocation Project as described in the background section of this document. This project is the final phase that allows GLWA to place the new section of WTM into service. The continuation of this relocation project is essential in providing improved access for future operations and maintenance of the 96-inch WTM. In addition, the completion of this project will increase resiliency of the water transmission main system with the installation of isolation valves allowing for operational flexibility and redundancy in the future.
FINANCIAL PLAN IMPACT

Fiscal Year
FY 2026 Plan $ 12,563,000.00
FY 2027 Plan 39,931,000.00
FY 2028 Plan 33,862,000.00

Proposed Contract Award 138,611,881.17
Estimating Variance $ (48,610,881.17)
The award of this contract provides a negative variance of $48,610,881.17. Consequently, the forecasted spend per fiscal year (FY) has been revised accordingly. The revised plan ensures that the CIP financial plan aligns with the project requirements for FY2027 - FY2031.
Additionally, FY2026 has sufficient funds allocated within the CIP; therefore, a budget amendment will be processed to transfer funds from capital reserves. Please note that there will be opportunities for value engineering (VE) once the design-build team is onboard, which will assist in managing expenditures for FY2027 and FY2028.
