Duration:

This course is approximately 3 weeks in duration.

Learning Method:

The PDDP program is more of a self-guided learning style.
You are required to read the notes and materials given, complete the follow-up assignments on your own, send in your questions prior to your 1 hour webinar meeting (if required) and be involved in live discussion via the internet.
Once you have completed the course, you will receive a certificate of completion

Course Description:

Strengthening and stabilizing soil and rock masses, and resisting structural movements are achieved by anchoring via prestressed reinforcement. To withstand lateral forces, temporary tie-backs in soil are also necessary for successful construction of shallow foundations.

Ground and Rock Anchors have vast engineering applications and could be used in many projects either within the new design phase or after construction to strengthen components.

Ground and Rock Anchors are important components of ground support, soil improvements, foundation underpinning, wall support and endless other applications. This course is focused on the design, construction and protection of Ground and Rock Anchors.

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.
