South Breakwall Repair
- LocationSheboygan, Wisconsin
- TimelineApril 2020 - March 2021
Michels rebuilt 1,250 feet of the South Breakwater of Sheboygan Harbor. Michels encapsulated the existing breakwater in steel sheet piles with an internal bracing system and filled the annular space of the structure with 13,000 tons of clear stone. Crews also removed and installed 5,000 tons of armor stone and scour stone on the channel side of the structure. Upon completion of the project, a 30-foot-wide by 1,250-foot-long of 1-foot-thick concrete cap will be installed.
Michels was also tasked with removing several obstructions in the water that were not present in project drawings. Larger equipment was required to excavate the obstructions as deep as 30-feet below water elevation.
