To ensure rapid and sustainable economic growth, strong support from the energy sector is required. Governments in Vietnam have invested in numerous hydropower projects, many of which employ the EPC (Engineering, Procurement and Construction) contract. However, the EPC general contractors are facing many difficulties, resulting in schedule delays and considerable losses. This research is conducted to highlight the main risk factors in the delays of hydropower construction projects in Vietnam. The research employs the method of statistical calculations and risk analysis to obtain feedback from experts participating in similar projects. The research outcomes are as follows: identifying the risks that can cause delays in EPC hydroelectric construction projects in Vietnam;calculating and classifying the degree of impact of each risk to the progress of the construction. The practical significance of this study is to ensure the timely completion of projects, benefits for the investors, and the EPC general contractors.展开更多

It has explored how clients, consultants and contractors prioritize causes of cost overrun in building projects in Tanzania and measured the statistical variance in their order of rank. A total of 55 respondents were selected from public projects that had experienced cost overruns. The results show an inclination of the top 4 causes of cost overrun being technical and originate from internal sources. The Spearman correlation coefficient established a strong positive correlation in the ranking of causes of cost overrun in construction project by clients, consultants and contractors, suggesting a shared cognition is in place for the project team. The outcome provides a good base for contemplating success of mitigation measures for cost overruns and reiterates the significance for a shared cognition for project team success.展开更多
