Determiners of Schedule Delay Risk of the Highway Project in Vietnam: Based On the SEM model

With the economic development of Vietnam in recent years, the highway construction develops rapidly and brings the international construction companies a good opportunity, but the phenomenon of schedule delays has a serious impact on the project investment efficiency, cost and reputation. In this paper, on the basis of former study and combining with interviews of Vietnam expert, we investigated the influential factors of highway construction schedule in Vietnam by the questionnaire survey in 2014, and evaluated the mutual influence of the above factors by using structural equation model (SEM). The empirical results showed that the 7 factors had significant impacts on the construction schedule delay. Finally, we propose the specific management sugges- tions to improve the international construction companies' ability of risk management when partic- ipating in the highway project contract in Vietnam.
