The paper aims at quantifying the human errors in the construction work and analysing theirpotential impact on the construction accident. It proposes to analysis the risks in the construction safetywith the human reliability analysis (HRA) method. The paper adopted a fuzzy Bayesian network (BNN)approach to incorporate the cognitive reliability and error analysis method (CREAM), which is one of therepresentative HRA method, into the construction safety analysis. This fuzzy BNN was developed into ahuman-centered
risk model. The model used the intuitionistic fuzzy sets (IFS) to represent the expert’sjudgment and generated the probability distribution by the mass assignment theory. A case study on thefireaccidentintheconstructionofXiamenMetroLine2inChinawasprovided.Themodelhasprovedto be able to analysis the construction accident from the human factor perspective and elicit meaningfulquantificationresults.
