The project involved the construction of approximately 8 miles of a new steel 54-inch transmission main for the Great Lakes Water Authority to connect their Eight Mile Road transmission system with their Fourteen Mile Road system. Major project components included:

Approximately 42,000 linear feet of 54-inch steel pipe installed by open cut and welded in place.
Over 15,000 feet of pipe was installed in tight right of way areas along the I-275, I-96 and M-5 freeways at a depth of over 17 feet. At some locations, the work area was less than 30 feet wide and had to be constructed along a highway sound wall.

Approximately 2,450 linear feet of 54-inch steel pipe installed on concrete capped piles.

Installation of 54-inch pipe via micro-tunneling under I-96, M-5, 12-Mile Road and Haggerty Road. The longest tunnel was approximately 700 linear feet.

Performing a hot tap on the existing 48” PCCP water main pipe along 8-Mile Road to connect the new 54-Inch steel pipe.

The installation of one new 50’ span and one new 60’ span concrete arch bridge for MDOT drains.

Removal and replacement of approximately 22,400 feet of bike path in the MDOT right of way.

The installation of 5 48-inch gate valves and valve vaults.

Installation of a complete cathodic protection system for the new pipe.

Careful planning and significant communication during construction was required with the local regulating communities, MDOT and GLWA in order facilitate this construction project. The work was performed along and under major Michigan highways and required the shut-down of Meadowbrook Road in Novi which affected traffic to a local school. This comprehensive project aimed to enhance water transmission efficiency and infrastructure integrity for the GLWA system. The project was completed on schedule with final testing and commissioning being completed in mid-2024.
