Abstract
Hazard evaluation is a critical task in safety management of construction projects because of their characteristics and dynamics. This study provides a framework to evaluate the project hazard index (PHI), which represents the hazard level of a construction project by using the possibility approach (fuzzy set theory). To achieve this objective, the study has been conducted in two phases. In the first phase, 10 hazardous trades and their physical attributes have been shortlisted and a three-level hierarchical structure has been constructed to evaluate the PHI. In the second phase, the methodology of evaluation and determination of the weight of each hazardous trade with its attributes were carried out using tools such as fuzzy measures, fuzzy integrals, fuzzy analytical hierarchy process (FAHP), and the weighted sum method (WSM). Correlation between the PHI and safety budget of several project sites owned by the Delhi Metro rail project validates this study. The PHI will be useful to differentiate the projects based on their project hazard level and accordingly, decisions can be made to improve safety management in construction projects. Application of fuzzy measure and nonadditive fuzzy integral, nonprobability (possibility) approach, and considerations of trades instead of activities are some of the key highlights and contributions of this study.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
