The latest issue of Deep Foundations Magazine is available online from the Deep Foundations Institute (DFI). The September/October 2017 issue cover story is about the 2017 OPA Winning Project – The Expansion and Preservation of the Andrew Mellon Building in Washington D.C. This project involved adding a basement beneath the existing foundations of the National Historic Landmark. Berkel & Company Contractors designed micropiles to serve as the shoring system and the permanent deep foundation elements.
DFI Announces the 2012 Outstanding Project Award Winner – The Route 9A Pedestrian Tunnel at the World Trade Center
Hawthorne, NJ (December 1, 2012): The Deep Foundations Institute (DFI) presented the 2012 Outstanding Project Award (OPA) to the Port Authority of New York and New Jersey for the design and construction of the Route 9A Pedestrian Tunnel at the World Trade Center in New York City. The award was presented to Robert Yin of the Port Authority of New York and New Jersey at the Awards Banquet during DFI’s 37th Annual Conference on Deep Foundations in Houston.

This has to be one of the most complex geotechnical engineering problems I’ve heard of for a building, if not for any kind of project. For starters, beneath the proposed 10-story office building referred to as Cannon Place lies the Cannon Street Train Station built in 1868. Also beneath the site are walls and foundations of a Roman Governor’s palace. In order to accommodate these features, the building has 21-m cantilevers at each end, with the load bearing happening over two groupings of columns at the 1/3 points. In section it looks quite like a 3-span bridge…without the abutments and stacked 10-stories tall! More after the break. (Images by New Civil Engineer) […]
Hawthorne, NJ (May 28, 2014): DFI announces the formation of a new, 16th technical committee focusing on site investigation for deep foundation design and construction.
The Subsurface Characterization for Deep Foundations Committee was formed to increase awareness of the importance of complete and competent site investigation in deep foundation practices. The specific goals of the committee will be defined by the committee members, however, initially the committee will discuss and define subsurface characterization needs from the point of view of the entire geotechnical/foundation industry. This will facilitate getting correct and comprehensive information to the end users (designers and contractors) and minimize change condition issues/debates. The committee will liaise with associated committees from other organizations and agencies to broaden the discussion within the engineering community. The objective is to find the common ground that allows the entire geotechnical industry and all project participants to minimize disagreement during construction, align expectations, and improve communication and understanding among related parties.
