Cleveland Harbor East Breakwater Repair

Cleveland, Ohio


The U.S. Army Corps of Engineers has contracted Great Lakes Dock & Materials, located in Muskegon, Michigan, for the Cleveland Harbor East Breakwater Repair Project in Cleveland, Ohio. For this project, Anthony Allega Cement Contractor, Inc. is a material supplier for Great Lakes providing the manufacturing of their dolosse. These dolosse are manufactured in Allega's yard and delivered to the dock for the structural repair of the breakwall.

DolosseA dolos is an interlocking concrete erosion control structure placed along the bottom of the lake and the side of the breakwall in order to prevent erosion of the wall. Allega commenced pouring dolosse on March 30, 2015 and discontinued production on November 18, 2015 due to weather. As of now, Allega has poured 9,038 out of 16,813 dolosse (53.76% complete), and it is estimated that the project should conclude in October of 2016.

Allega pours 52 dolosse each day, which are formed in custom made molds, using its on-site batch plant and concrete mixer trucks. A Grove RT Crane is used, along with an attached side load concrete bucket, to pour the concrete into each mold with care. Allega lets the concrete set overnight before moving the dolosse with two Komatsu PC-490 excavators to store in our yard before transporting them to the dock. After the dolosse are delivered to the dock, Allega then utilizes a Komatsu PC-1100 to load them onto the barge for Great Lakes Dock & Materials where they will then be transported to the appropriate location to be placed in the water on the breakwall.Dolosse

What is unique about this project is that dolosse have not been manufactured in Cleveland or the Northeast United States since the 1970s. The reason behind this repair is to stop the erosion of the breakwall and keep Cleveland’s harbor safe for the public from storms and rough water.
