After the collapse of Can Tho Bridge, a severe accident with 54 people dead and 80 injured, the risk assessment of sustainable concrete structures for Vietnam construction industry becomes an extremely important subject. In spite of many accidents in construction, there is still no research in the risk management of construction industry in Vietnam. Based on the situation, "Development of Risk assessment system for Sustainable Concrete Structures with Construction Management in Vietnam" has been conducted. The first survey was conducted with the cooperation of experienced person who has responsibility in construction-related companies in Vietnam. In order to collect actual data concerning the cause, the type and the probability of various incidents, the repair cost after the failure occurrence and the proactive cost with purpose of incident prevention to prolong the life of concrete structures and reduce the life cycle cost in Vietnam. As a result of this investigation, Event Tree Analysis (ETA) is used to classify and evaluate the damage form, identifying the occurrence probability and the cost of loss. This research estimates 26 types of failure (hazards) which might be occurred in concrete construction, based on the assumption that hazard occurred dependently. Based on ETA, each failure is disposed into 4 cases. Some case of risk curves are used to identify and evaluate the sequence of events in the failures. By this result, construction companies in Vietnam have been aware of preventing construction failure that might be occurred. Comparison was made between the results in Vietnam and those in Japan to find out appropriate measures to minimize the risk in concrete construction.
