About the course

This course will provide tools to assess the serviceability and the life span of concrete structures, to evaluate the actual capacity of the structure versus life span and life cost, and define the best strategy for assessment and rehabilitation of concrete structures as well as the maintenance or repair through practical applications. The structural dysfunction and failure is the result of human error originating from oversight, negligence, ignorance or the lack of knowledge.

Structural malfunction may be characterized as the unacceptable difference between intended and actual structural performance. A better knowledge and a deeper consciousness of our professional, human and social responsibilities can lead to the construction of safer and better performance buildings.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Identify the critical characteristics of a given structure, types and causes of common deficiencies (even failures) of structures
  • Explain the methods of observation, instrumentation and testing
  • Apply preventive measures to counteract deterioration of structures
  • Comprehend workable temporary and permanent repairs for any particular structure
  • Use a comprehensive practical guide on the practice and business of assessment of site conditions and evaluation and repair strategies and techniques of concrete structures, or others structures
  • Understand the nature of innovative technology and provide an overview for the role of effective management
  • Recognize the important role of the designer, the contractor and the supervision in producing sound structures
