Description

The deterioration of concrete structures is a very serious problem. 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 to initially mitigate the deterioration and ultimately restore concrete structures to safe, serviceable conditions.
 
In many cases, the evaluation of existing concrete structures is done by visual inspection.  However, many defects are not evident either because they are physically concealed, as in underground components, or lie beneath surfaces as in corrosion damage or cracking.  Likewise, once located, the impact of these defects on service life is difficult to determine.  Selecting appropriate and cost-effective rehabilitation measures is often hampered by limited information on the structural defects.

Engineers and other professionals need to keep abreast with the latest advances and recent successful experiences gained in the diagnostic methods, new materials and methods for the rehabilitation and upgrading of concrete structures. This course explains the mechanisms responsible for the deterioration of concrete structures, the methodology to inspect such concrete structures, as well as the materials and techniques that can be used for their protection, rehabilitation and repair. Participants will learn how to identify the causes behind the degradation of concrete structures, how to assess the risks associated, and how to mitigate those risks using informed decision making and sound repair and rehabilitation techniques. Case studies and observations from real world structures will enforce the learning process and participants will have opportunity to discuss real cases they have been exposed to in their professional practice.

Objectives

To provide the information needed to identify the deterioration mechanisms, design and implement a professional Condition Assessment Program by identifying the tests that complement visual inspection, the concrete condition information that can be obtained from the tests, and how this information should be interpreted for protection and rehabilitation of concrete structures.

Who Should Attend

Construction and structural engineers, designers, owners, consulting engineers, architects, technicians and technologists, contractors, facility managers, construction inspectors, inspection agency officials or building managers with responsibility for maintenance or rehabilitation of both public and private concrete structures, as well as manufacturers and suppliers of speciality products and those who need to know what testing methods best apply.

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
