Earlier research works on fire risk evaluation indicated that an objective,reliable, comprehensive, and practical fire risk evaluation model is essentialfor mitigating fire occurrence in building construction sites. Nevertheless,real empirical studies in this research area are quite limited. This journalpaper gives an account of the second stage of a research study aiming atdeveloping a fuzzy fire risk evaluation model for building construction sitesin Hong Kong. The empirical research findings showed that the overall firerisk level of building construction sites is 3.6427, which can be interpretedas “moderate risk”. Also, the survey respondents perceived that “Restrictionsfor On-Site Personnel” is the most vital fire risk factor; with “Storage ofFlammable Liquids or Dangerous Goods” being the second; and “Attitudeof Main Contractor” the third. The proposed fuzzy fire risk evaluationmodel for building construction sites can be used to assess the overall firerisk level for a building construction site, and to identify improvementareas needed. Although the fuzzy fire risk evaluation model was developeddomestically in Hong Kong, the research could be reproduced in othernations to develop similar models for international comparisons. Suchan extension would provide a deeper understanding of the fire riskmanagement on building construction sites
