Flexible & Rigid Retaining Wall Systems Design Workshop (1.2 CEUs)

Daily Schedule:

12:00pm MST - Session begins
3:00pm MST - Adjournment
This course is divided into four sessions. Each session will be 3 hours in duration. The sessions will be held on April 12, 13, 19 & 20.
If you are unable to attend any of the sessions a recording will be made available.


To present an in-depth review of design, application and construction of flexible and rigid retaining walls systems.
The goal of this course is to provide participants with state-of-the-practice design tools and construction techniques to expand implementation of safe and cost-effective earth retention technologies. This course addresses the selection, design, construction, and performance of earth retaining structures used for support of earth fills and excavations or cut slopes. The instructor covers factors that affect wall selection. Class discussions will include design procedures and case histories, demonstrating the selection, design, and performance of various earth retaining structures. Detailed information on subsurface investigation, soil and rock property design, parameter selection, lateral earth pressures for wall system design, and load and resistance factor design (LRFD) for retaining walls is provided.
After Attending This Workshop You Will Be Able To:
Recognize potential applications for retention structures used in civil engineering practice
Select the most technically appropriate and cost-effective type of retaining wall for the application, based on a thorough knowledge of available systems
Examine and select appropriate material properties, soil design parameters, and earth pressure diagrams
Prepare conceptual and basic (i.e., for simple geometry) designs using appropriate design methods, factors of safety, earth pressure diagrams, and field verification methods, and be able to appraise contractor-submitted designs
Demonstrate a clear understanding of retaining wall construction and maintenance design rigid and flexible retaining walls systems
Analyze retaining wall failure and understand reasons behind it
Design simple reinforced slopes using geosynthetics
Have a better understanding of retaining structures in terms of design, applications, development limitations and construction
Be able to compare different retaining systems and make an informed decision based on the technical and economic feasibility of each system

Dr. Gamal Abdel Aziz

Dr. Gamal Abdelaziz, P.Eng, MSc. has a Ph.D. in Geotechnical Engineering from Concordia University, Montreal, Canada.

Dr. Abdelaziz has served as a senior geotechnical engineer at DST Consulting engineers, Sarafinchin Consulting engineers, Trow Consulting and EBA engineering. Currently he is the managing director of SAGA Engineering, Edmonton, AB, Canada. 

Dr. Abdelaziz has over 32 years of experience in geotechnical and structural engineering, foundation design, teaching, research and consulting in Canada and overseas.

Dr. Gamal has designed and delivered over one hundred geotechnical engineering workshops which are very well received by practitioners engineers in Canada and globally.

Currently he is a senior geotechnical engineer with SAGA Engineering, Edmonton, Alberta. His duties include revision of geotechnical design, including slope stability, foundation and machine foundation design, soil investigation, design of cuts and earthfills, evaluation of stability of existing slopes, slope reinforcement using geotextiles, geogrids, soil nails, base reinforcement to support earthfills on soft subgrade soils, Erosion protection using geocells matting, rip rap, stabilization of unstable slopes, evaluation of soil bearing capacity to support footing foundations, Settlement studies, deep foundations including driven piles, auger injected (CFA) piles, additional support to existing foundations by underpinning utilizing concrete panels, grouting, micropiles, evaluation of earth pressures on retaining walls, security of excavation base, tieback support, etc.

Dr. Abdelaziz is a former adjunct professor at University of Western Ontario, London, Ontario, Canada, visiting professor at Ryerson University, Toronto, Canada and part time professor at Seneca College, Toronto, Canada.

Dr. Abdelaziz is specialized in numerical modeling for solving sophisticated geotechnical engineering problems with respect to pile foundation and the linear and nonlinear analysis of soil-structure interaction. He designed charts to predict pressures acting on tunnels, and developed an analytical model for pile bearing capacity prediction.

Dr. Abdelaziz authored a number of technical papers and delivered numerous internal and external workshops on various geotechnical and Municipal engineering topics. Dr. Abdelaziz has been involved in a number of projects in Canada and overseas, such as tunneling, silos, buildings, retaining structures, siphons, irrigation networks and many other civil engineering projects in terms of design and construction.

Education @ Your Desk. A Live Webinar Class means that you will attend the class via the web using your computer. There are scheduled breaks for coffee and lunch. You use a microphone, headset, or your phone and are able to interact with the instructor and other students while following notes while watching the presentation slides online just as you would in a live classroom. Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at info@tlnt-training.com for Special Group & Corporate Rates for one or more participants.

We could offer any of our courses at a location of your choice and customized contents according to your needs, please contact us at : inhouse@tlnt-training.com or click here  to submit an online request.
