Project Details

Threats from high water levels on Lake Michigan and violent storms left the City of St. Joseph with minimal time to bolster protection for the north pump station. Water levels had risen six feet since 2013 and the low revetment was no longer enough to protect the station. Water plant supervisor, Greg Alimenti, relied on Abonmarche’s expertise which allowed for accelerated delivery utilizing the City’s direct procurement of materials and heavy construction contractors who were already on-site.

Stone began arriving in December 2019 and Abonmarche worked directly with City staff and site contractors to refine a design that would protect the pump station. From concept to completion, the project took only four months; half the time of a traditional process. Further, due to the efficiency of the design-build process, the City cut the cost by approximately 50%. The project not only repaired damage, but enhanced the level of protection by increasing the elevation and thickness of the revetment.
