The study aimed to asscess the influence of factors on the delay construction. The study has conducted analysis to identify the risk factors that cause delay in construction, thereby conducting surveys of individual involved in the design, construction, supervision and management project. After 310 valid samples, the statistical analysis software was used to quantify the influence of factors. Through quantitative analysis showed abnormal factors on construction site such as labor accidents, hydrological factor, flow, extreme weather, etc and technical factors related to the contractor such as unreasonable schedule, outdated construction technology, unprofessional wokers, etc that have the greatest impact on delay construction of irrigation and hydropower projects in Vietnam.
