ABSTRACT: Water is one of the developments
that Vietnamese government has already committed and this sector always plays
an important role in socio-economic life of Vietnam. The Government and
Vietnamese people have been trying to improve infrastructure, enhance living
standards for people and national socio-economic development. However, in terms
of water, Vietnam still has to face many challenges that require a lot of
efforts to deal with. Now, in Hanoi, especially the outskirts of the city,
there is a huge lack of water works, causing negative impacts on community’s
life and the quality of environment. Water distribution systems play a critical
role in supplying sufficient water to users with acceptable quantity, pressure,
and quality. Risk assessment has been recognized as a useful tool to identify
the hazard, analyse vulnerabilities, and risks, and select proper mitigation
measures. A questionnaire has been designed including 51 factors that create
risk events that can occur during construction works implementation. Risk
matrix was used as basis for quantitative risk analysis to determine the most
critical risks which were a great impact on project and also to indicate
moderate risks that must be taken into consideration. The study analysis and
assessment of risks are based on survey questionnaires, which achieved the
following findings: 1) there are 26 main risks influencing schedule delays; 2) scientifically
ranks influence every single risk on schedule delays; 3) making recommendations
can reduce or eliminate influencing factors. This study provides a valuable
reference which helps investors and contractors finish on schedule to ensure
the benefits when building the Water Supply Projects.
