Description
Helical foundation systems offer a versatile replacement of conventional deep foundations solutions. The most important differences between the helical foundations and the conventional foundation types are mainly in method of construction. Helical piles need much less construction time and could be used or loaded immediately. Helical piles could be used where conventional deep foundation cannot. Underpinning is the best example of these unique differences. This course will focus on the design, construction and field acceptance criteria’s for the helical (screw piles). The course notes, lectures and hands on design examples will compose a comprehensive reference for the state of knowledge and guidance for future use.
The fundamental mechanisms by which helical piles develop resistance to load are described in a manner consistent with basic principles of soil mechanics. Along with the thorough description of installation methods and equipment that is provided, the concepts used for design and quality control/quality assurance follow logically. The section on corrosion and life expectancy is particularly important now as applications of helical piles expand into greater use with permanent structures with longer intended service periods. Applications for helical piles are described which may prove novel to many engineers and open opportunities for innovation and development of more cost-effective solutions.
 
After Attending this course you will be able to:
  • Determine screw pile carrying capacity
  • Select best screw pile type for your projects
  • Evaluate the helical pile acceptance criteria
  • Design helical foundation system with more confidence
Target Audience
This workshop will be suitable for Structural engineers, geotechnical engineers, technicians, and technologists. Civil engineers, public works and construction department employees of federal, provincial and municipal governments and engineers responsible for large industrial, commercial or institutional facilities who must deal with different types of foundations.
The course will be of interest to a wide range of practising civil engineers at different stages in their careers. Some familiarization with soil mechanics is desirable but the knowledge is not required at a specialist level.
 
Special Features
The two-day course will consist of a series of lectures and workshops. Worked examples with numerical reference will reinforce the lectures. Case studies which illustrate the full range of problems are a feature of the course. There will be workshops on helical pile design under different types of loads; a display of DYNA 6 modelling of pump station on screw piles will be displayed.
 
Objectives
The main objective of this workshop is to enable participants to select the best helical foundation solution for different types of civil engineering problems. After completing the course participants should be able to design helical foundations and supervise their construction. Understand the acceptance criteria, and related equivalent torque design. The course philosophy is to provide the participants with the information they need to design foundations at the state of the art. The information is supplied in a simple and systematic way, discussing topics where current knowledge is lacking and more understanding is needed.
 

The PDDP Distance Education program works as follows:

  • Once you register for this course, you will be sent a login username and password for our online distance website.

  • You will receive the course notes in hard copy through the online website, you will receive a set of notes each week covering the course material.

  • A one hour video-conference session will be conducted by your instructor each week (if required). The objective of this session is to assist in solving the assignments, as well as answer student questions that should be sent to instructor early enough prior to the meeting time. In addition with being able to communicate with the instructor, you will also be able to communicate with other students in the same class and watch their questions being answered as well. (A high speed internet connection is strongly recommended for this feature).

  • Each set of exercises can be completed and submitted by the indicated date and your completed exercise will be marked online and and returned by your instructor.

  • To gain the most from your course, it is highly recommended that you participate fully in all discussions and exercises. Please remember that each course has a form of quiz or exercise at the end to test your understanding of the material. You will be informed of these dates when you receive the course schedule.

*Course commencement date is subject to instructor availability.
