Introduction:

Structures like people never get younger. Structures, like people can maintain their good health with age, if properly inspected, cared for, examined when ill, maintained, and repaired when needed. 



It may be said that a concrete structure that has withstood the combined effects of use, abuse, loads, and environmental conditions over time has, in fact, proven itself. However, buildings and other structures do deteriorate with time because of repeated loadings, exposure to the elements, aging of materials, wear and tear from normal use, abuse, inadequate maintenance, and other factors.



Engineers and managers working in the field of inspection, construction and maintenance of concrete structures often feel the lack of a comprehensive practical guide on the practice, needs and effective programs of good maintenance. Few practical references are available that bridge the gap between theoretical, technical, practical and managerial matters in this regard.

This course is planned to answer technical questions frequently asked by the experienced engineer and executive. It includes information about the significance of applicable codes and standards, critical characteristics of a given structure, and causes of common deficiencies of structures, workable preventive measures for the decay and deterioration of concrete structures, maintenance work types, root cause analysis, comprehensive check list library and the use of innovative technology and new materials.

Who should attend:

This course is designed to meet the needs primarily of managers, engineers and technicians, working in the area of construction engineering, and facing the challenges of maintaining and preserving good, sound concrete buildings. It is also useful for quality assurance experts, construction and supervision engineers and technicians, owners and managers of constructed facilities. 

It is expected that a number of the attendees will find the information beneficial and a useful addition to their reference library even though they are not directly practicing in the field. 

Engineers involved in design, supervision, construction or planning will find many direct links with their practice and requirements and can put the information provided to use immediately.
