| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 101 === Construction is a risky industry and there is no other industry that requires proper application of business practices much as construction industry. The main objective of this research is to gain understanding of 35 risk factors that could be faced in multiple usage and commercial building projects in Vietnam. The study aims also to investigate the effectiveness of risk preventive and remedial methods. Moreover, the usage of risk analysis techniques is addressed.
The objectives of this research have been achieved through a comparative study of closed-ended questionnaires and a case study in Vietnam. The results of analyzing the questionnaire that were directed to contractor respondents concluded that the most important risk factors are: occurrence of accidents, contractor’s financial failure, unqualified designer, incorrect design and delayed disputes resolution. The results show that there are many risk factors contractors could not allocate them on the party that should bear these factors’ consequences. The study findings show that the contractors suffer from lack of innovative methods to prevent or mitigate risks. Contractors – according to results – do not utilize risk analysis techniques but depend widely on direct judgment in estimating time and cost.
The results of this study recommended that there is an essential need for more standardization and effective forms of contract, which address issues of clarity, fairness, roles and responsibilities, allocation of risks, dispute resolution and payment. Contractors need to identify possible risk factors that could be faced and to allocate them contractually. There is a need to keep a computerized historical data of finished projects to help in rights reservation and to be an information source for future comparison. A standard form of contracts which address issues of clarity, fairness, roles and responsibilities, allocation of risks, dispute resolution and payment should be adopted for all the construction projects in Vietnam instead of the consequential disorder that was a result of applying different types of contracts. More effort should be made to properly apply risk management in the construction industry.
