Developing a Versatile Subway Construction Incident Database for Safety Management

It is very difficult to implement quantitative risk assessment (QRA) for safety management in subway construction because of to the shortage of sufficient information about accidents happening in subway construction. QRA contains, for example, the statistical analysis of incidents, the calculation of safety precursors, and a foundation of precursor early warning systems. To enhance the possibility of QRA and further the safety management in subway construction, a versatile subway construction incident database (SCID) was developed. SCID is composed of three kinds of incidents—inclusive of accidents, near-misses, and unsafe behaviors/conditions. First, this paper researched in-depth on the relationship and differentiation among incident, accident, near-miss, and unsafe behavior/condition, and the methodology of data collection about subway construction incident was represented. Second, Microsoft…
