87 Adjacent Structure Technical and Legal Risks

PRESIDENT'S MESSAGE

Scott J. DiFiore, P.E., Gregory R. Meeder, James P. Chivilo and Matthew H. Johnson, P.E.
Heavy civil construction in urban
environments can damage existing,
adjacent structures through ground
movement and vibration. Owners of
new construction projects and their
team must be aware of legal and
technical risks posed by excavation,
dewatering and demolition to navigate
and allocate those risks. This article
discusses approaches to early and
frequent communication among project
participants that are necessary to
manage risks, regardless of local
regulations that may or may not exist to
drive risk-related processes.

95 Micropiles to Improve Stability of Factory
Machining Centers
Glenn Patterson
Modern manufacturing facilities employ a quick production
pace and precision machines that work with few interruptions. The large machining centers involved require an
independent foundation that is free from vibrations of all
other shop machinery and equipment. As a result, micropiles
can improve installation of machinery due to their minimal
impact on factory schedules, speed of installation, small
footprint of installation equipment, and ability to create
lasting, competent foundations for machinery.

103 Improving Helical Pile-to-Foundation Connections
Serhan Guner, Ph.D., P.Eng., and Sundar Chiluwal
Many structures are subjected to sequential applications of compression and tension
loads due to events such as windstorms. Tall and light structures that are particularly
vulnerable to the tensile components of cyclic loads can be developed with helical pile
foundations as part of addressing this. DFI's Helical Pile and Tiebacks Committee
funded a research study to help evaluate current helical pile designs and inform the
development of more robust helical pile-to-foundation connections.
