Abstract
The New York Harbor Siphon project involves construction of a 1.8 mile long 12-foot diameter tunnel beneath the New York Harbor, using a pressurized face tunnel boring machine. This subaqueous crossing will be the first of its kind using pressurized face tunneling technology in New York City. A steel water main inside the tunnel will connect water distribution systems on Staten Island with Brooklyn. The project is being managed by the New York City Economic Development Corporation on behalf of the owner, the New York City Department of Environmental Protection, and the Port Authority of New York and New Jersey. This paper outlines the complex geological conditions and highlights key design and construction considerations.
