Project Details
Abonmarche designed and oversaw the reconstruction of 1,618 feet of roadway on Madison Avenue, 5th, 6th, and 7th streets. This project included reconstruction of driveways and sidewalks within the road right-of-way, upgrades to the City’s utility system, replacement of the storm sewer system, replacement of the water main and water services to homes and businesses within the project limits, and replacement of the sanitary sewer and service laterals. We designed a new sanitary sewer that relocated a major sanitary trunk sewer from beneath US-31 just south of the Grand River. This allowed better access to a critical component of the city’s wastewater collection without the need to impede traffic on this busy stretch of State Trunkline.
The water table in this area was determined to be at four feet below the ground surface. This was likely the reason that water mains were constructed very shallowly in the past. Abonmarche’s team was able to design the water and sewer improvements, including a dewatering system, to ensure proper burial depth. This also included buoyancy calculations to ensure the pipe wouldn’t “float.” As a result, the 24-inch sanitary trunk sewer was specified as concrete pipe.
