Charleroi Locks and Dam Facility

Pittsburgh, Pennsylvania

DLZ was contracted by the U.S. Army Corps of Engineers, Pittsburgh District for the stabilization of the existing Middle Wall at Charleroi (Mon 4) Locks and Dam. This delivery order consisted of performing design level investigations, calculations, and other analyses required to develop various options for stabilizing the existing middle wall.  Once stabilized, the existing middle wall was used as part of the cofferdam for constructing the new locks; the new project name will be the Charleroi Locks and Dam.

This stabilization ensured uninterrupted operation of the existing land chamber for transport of commerce while work commenced for the new locks within the existing river chamber.  When work is completed, the entire project will be one of the most efficient waterways in the world. The narrow and antiquated existing locks at Charleroi, which are located just south of Pittsburgh, are more than 70 years old and are the last major bottleneck in the U.S. Army Corps of Engineers nearly $1 billion plan to improve navigation on the river.
