A research paradigm for developing a fire risk assessment model for new construction sites in Hong Kong

Abstract

In Hong Kong, the construction industry is regarded as high-risk. Amongst all types of construction accidents, however, industrial practitioners tend to give less attention to those related to construction site fires, that is, fires which occur during new construction. Fire is perceived as a significant but common risk associated with construction projects which can lead to serious damage. Although construction site fires may not be frequent, the consequences are usually severe. This paper will present an overall research framework for developing a fire risk assessment model for new construction sites in Hong Kong. The research process mainly involves the identification of key fire risk factors and their associated sub factors contributing to fire risk for a construction site, and the development of a fuzzy fire risk assessment model based on the identified fire risk factors. The research methods to be adopted include desktop literature review, Delphi survey technique, empirical questionnaire survey and fuzzy set theory. The model can be used as an objective tool for measuring and comparing the overall fire risk levels existing at different construction sites. Therefore, high-risk areas could be identified and improved. The research findings from the developed fire risk assessment model will ultimately lead to the provision of remedial measures to reduce fire risk at new construction sites. Although the research study will primarily focus on the prevailing situation in Hong Kong, the research methodology will be applicable to many other parts of the world for facilitating international comparisons.
