TRAINING.

Overview

After participating in this course, you will be able to:

• Diagnose durability problems
• Apply non-destructive testing methods
• Design surface repair strategies
• Identify the best materials for repair
• Achieve cost-effectiveness in restoration projects

Description
Despite the costly and tragic failures of some North American concrete structures, there is currently a lack of guidelines and procedures for assessing, testing, classifying, and prioritizing preventive and corrective action for these structures. This course focuses on training participants to properly diagnose the root causes of damage in concrete structures, develop effective repair strategies, and select the right repair materials.

Case studies and observations of existing structures will enhance the learning process, and participants will have the opportunity to discuss actual cases that they have been exposed to in their professional practice.

Who Should Attend
Designers, Construction and Structural Engineers • Project Managers • Technicians and Technologists • Engineers in Training • Construction Inspectors • Inspection Officials • Facility Managers • Architects

Instructor

Moncef L. Nehdi, Ph.D, P.Eng., FCAE, FEIC, FACI, FCSCE, FAAIA

Dean, College of Engineering and Physical Sciences

Moncef received his BASc from Laval University, MASc from Sherbrooke University, and Ph.D. from the University of British Columbia, all in civil engineering. He is currently dean of the College of Engineering and Physical Sciences at the University of Guelph. He was previously professor and chair of the Department of Civil Engineering at McMaster University and professor of Civil and Environmental Engineering at Western University, where he also served as associate director for Environmental Research Western.

His industrial experience includes serving as technical manager for three different companies. He was licensed as a professional engineer in British Columbia in 1998 and in Ontario in 1999. He is the past chair of the ACI committee 555 on recycled materials, past chair of the CSCE sub-committee on cement and concrete, past chair of the CSCE Materials and Mechanics Division, is deputy chair of the RILEM committee on concrete data science, and was co-chair of the Infrastructure Division of NSERC’s Discovery Grant Committee 1509. He has provided consulting services for some world landmark projects, including some of the world's tallest buildings, the world’s largest airport, the world’s most venerated pedestrian bridge, and the world’s deepest and second-largest water treatment plant.
