Drilled Shaft Foundations for the Float-in Dam on the Monongahela River at Braddock, PA (6c19e969-5f09-43f8-9e6e-1837d4537e5e)

The new gated dam on the Monongahela River at Braddock, Pennsylvania, was built for the US Army Corps of Engineers using an innovative "In-the-Wef' technology. A key feature of this technology involves construction of the foundations through the water and later mating the completed structure or a shell of the structure to the pre-installed foundation. This paper presents a description of the structure, its foundation, construction sequence and design details required to successfully Implement this technology.
