The present study aimed to evaluate the relative importance of risk factors for the construction of general hospital. This work was particularly framed using the evaluation methodology of analytical hierarchical process (AHP). A careful literature review along with the experts’ opinions led to the development of a total of four risk factors, including planning phase, design phase, construction phase, and maintenance phase. Four specific indexes were developed from each of the four criteria by the assessment of survey data collected from a total of fifty-five respondents who participated in the first-round study. Furthermore, five risk factors were identified corresponding to the perspective of two stakeholders of contractor and constructor, respectively. A set of pairwise-comparison data were collected from forty-nine respondents who participated in the second-round study. The result from the AHP analysis indicated that, (1) the planning phase was found to be the most important risk factor for the construction of general hospital, (2) the risk index of project scale emerged as having the greatest score in global weight, follwed by location suitability and unreasonable construction period estimation, (3) construction duration forecast, construction scale and cost forecast error, capability of construction companies, selection of contractors and poor handover were found to be the most important risk index for the data set of contractor, and (4) occurrence of safety accidents during construction, construction period delays, unreasonable shortening of construction period, safety accidents during construction as well as demand for additional construction rank in the highest priority.
