| Note | This research focuses on the identification of major risk factors faced by parties involved in hydropower tunnel construction in Vietnam and investigates into the risk allocation opinion among the involved parties. The data collections were carried out by structured interviews at two hydropower tunnel construction projects in Vietnam. Beside, the research also investigated into the risk allocation practices at the two projects to find out whether the risks in these projects are allocated properly or not. The results of risk identification obtained at the two tunnel projects indicated that, in general, the two tunnel project facing the same risks; however, some of the risks are somewhat different in rank between these tunnel projects because they used different methods of construction. Tunneling by TBM, which is more mechanized than tunneling by drill and blast method (D&B method), faces more risk about equipment productivity and ingress of ground water but less risk about overbreak. Opinions on risk allocation were also obtained at the two projects. Hypothesis tests pointed out that there is no conflict of opinion about risk allocation between the owner and the contractor in tunnel construction in Vietnam. Furthermore, risk allocation practices at the two projects have been investigated. Although there are some conflicts about policy perception for risk allocation between participants in the projects, majority of participants are satisfied with the current risk allocation arrangement in their projects. |
