solution at the urban site were key considerations for the project
team. DuroTerra, LLC and GeoStructures, Inc. recognized that the
ground conditions and practical construction constraints were
well-suited for a ductile iron pile (DIP) system. After initial exploration
of the foundation options, the DIP system was selected
because of the ability to work on the congested site, the modular
and self-contained nature of the operation and low vibration levels
to allow work immediately adjacent to the property lines.
DIPs, manufactured by Austrian-based Tiroler Rohre GmbH
and distributed throughout the Americas by DuroTerra, are a low
vibration, modular driven pile system. The pile sections are manufactured
in five-meter (16.4 feet) lengths that feature a unique Plugand
Drive (bell and spigot) connection. The Plug-and-Drive system
forms a rapid, moment-resisting connection when driven using a
high-frequency percussion (demolition-type) hammer mounted
on a medium-sized excavator. The combination of the connection
and high-frequency energy enables the piles to be driven efficiently
to considerable depths while also generating minimal vibrations
compared with traditional driven pile operations. The modular
nature of the system and relatively small installation equipment
makes it well-suited for constrained urban sites where material
storage and laydown are a challenge or interior renovation work
where overhead clearances are typically 18 feet or higher.
While the system has been used cost-effectively on wide-open
sites, many projects include building additions, interior retrofit
work or tight, urban development sites. DIPs are manufactured in
various sizes (diameter and wall thicknesses) to develop working
