The Howland Hook Terminal Facility located in Staten Island, New York is one of the most active container terminals in the Northeast United States. Due to the high capacity of the facility, the Port Authority of New York and New Jersey (PANYNJ) recently acquired the adjacent 37-acre Port Ivory Facility. Expansion of this Site facilities the additional transfer of goods for rail transport, where formerly the facility was solely highway transport. Upon completion, the facility will have the ability to transfer containers directly to a freight rail line onsite by crossing from Howland Hook Site to the Port Ivory Sit via a proposed bridge over Bridge Creek. The geology of the Port Ivory Site consists of shallow glacial deposits left by the leading edge of the last advance of the Wisconsin Glacier. Glacial and marine action over the millennia and the modifications of the past construction combined to form a challenging site geologically. Prior to the PANYNJ acquiring the site, the Port Ivory Facility was occupied by Proctor and Gamble for nearly 100 years. Over the course of time, the site has had a variety of structures constructed and demolished at the site. The earliest structures were often supported on shallow foundations and the foundation types used progressed over the years transitioning from low capacity timber piles, steel piles with concrete cores, precast piles and cast in place foundations. Currently, we are designing 4-foot diameter high capacity drilled shafts to support a new bridge over Bridge Creek to connect the two sites. Drilled shafts proved to be a very economical solution from both a design and construction point of view to carry the axial load of the bridge of approximately 400 tons per shaft. The paper will present a historical evolution of the progress of deep foundation types used at the Port Ivory Site; from low capacity timber piles to high capacity large diameter drilled shafts. The paper will also present changes and modifications of geotechnical design criteria over time that affects the type of deep foundations used. For instance, utilizing new seismic design criteria requires selecting a deep foundation system that withstands seismic loading conditions and overcomes the effects of liquefaction.
