Deep Foundations Institute’s (DFI) Helical Piles and Tiebacks Committee is hosting a one-day seminar on the detailed design, application and installation of helical piles and tiebacks for new construction and rehabilitation. The seminar is being held in Montreal, Que. in mid-September.
Seminar topics include axial, lateral, uplift, seismic, cyclic and dynamic loading, settlement analyses, materials, construction and testing procedures for helical projects.
Specific presentations will focus on a number of topics:
- Design and construction of helical piles and helical tiebacks.
- Seismic performance of helical piles.
- Building codes related to the design of helical pile elements.
- History and evolution of helical pile systems.
- Quality control, load testing and inspection.
- Developments and innovations in design, construction processes and equipment.
- Research advancements.
- Innovative and challenging case studies on the design and use of helical piles systems and helical tiebacks on new and retrofitted projects.
Keynote speakers for the event are Dr. Hesham El Naggar of University of Western Ontario and Dr. Amy Cerato with University of Oklahoma.
Hesham El Naggar, Ph.D., P.Eng., is a professor of geotechnical engineering and associate dean of engineering at Western University and the associate editor of the Canadian Geotechnical Journal. He has 30 years of experience in analysis and design of foundations and soil-structure interaction; and has published more than 270 technical papers in this field. Dr. El Naggar is a fellow of the Engineering Institute of Canada and has won several awards including the 2007 A.G. Stermac Award, 2002 G.G. Meyerhof Award and 2002 Canadian Geotechnical Colloquium Speaker.
Amy Cerato, Ph.D., P.E., is a Rapp Foundation presidential professor in the School of Civil Engineering and Environmental Science at the University of Oklahoma, and a recipient of the 2009 Presidential Early Career Award for Scientists and Engineers (PECASE). Dr. Cerato is a geotechnical engineer whose research includes predicting expansive soil behavior using microscale properties and foundation design for alternative energy. An active member of DFI’s Helical Pile and Tiebacks Committee, Dr. Cerato and her graduate students have been spearheading a Helical (Screw) Pile Seismic Research Study, which is partially funded through DFI’S Committee Project Fund.
The event chair is Dr. Yasser Abdelghany, P.E., a geotechnical engineer and the construction standards and contracts engineer of the British Columbia Ministry of Transportation and Infrastructure. Dr. Abdelghany is a visiting professor at University of Victoria (UVIC) New Civil Engineering Department (Geotechnical Engineering) and at Western University (UWO) Civil and Environmental Engineering Department.
The DFI Helical and Tiebacks Committee is meeting before the event, and encourages participation from seminar attendees and industry professionals in Quebec. The committee includes manufacturers, engineers, academics, suppliers and experienced contractors who constitute a forum for advancing the applications, understanding and use of helical pile and tieback foundation elements.
The committee will be discussing its new Helical Pile Design Guide, the development of a Helical Piles and Tiebacks Certification Course, and a new research project led by Dr. Ramin Motamed, assistant professor with the department of Civil and Environmental Engineering, University of Nevada, Reno. The project, funded by DFI’s Committee Project Fund and Ram Jack, involves conducting scaled liquefaction tests on helical piles and driven piles to experimentally evaluate the performance of the piles as an alternative solution in mitigating the settlement of shallow foundations in liquefiable soils.
