Summary: Irrigation and hydroelectric works have many characteristics compared to other types of works because they are greatly affected by weather, climate, hydrology conditions, etc. Many irrigation works are delayed in construction, affecting expense and wasting to investment budget A survey of 310 samples was collected and analyzed to assess the impact of risk factors on construction schedule and was presented in the relevant articles by the author. The research results have shown that there are 6 groups of risk factors that cause construction schedule: (1) Group of technical-related factors, (2) group of factors related to abnormal impacts on the construction site, (3) group of factors related to people, (4) group of factors related to the process.
(5) group of factors related to design, (6) group of factors related to legal. Based on those studies.
Ihe paper aims to assess and rank risk factors to propose risk management measures in managing the construction schedule of irrigation and hydropower projects in Vietnam.
