Opportunity Efficiency - Use Uncertainty Analysis to Evaluate Risks in Construction

Abstract
In central Taiwan, around the Taichung basin, the ground condition is boulders with red soils and high ground waterlevel. Local technicians have developed an unusual soil excavation method to build the so-called “soil retaining
columns”. It is cheap, practical and highly efficient. However it is fraught with risk and uncertainty.
In general, use of the injury severity method in occupational injury evaluation is a good solution. But, the method seems
unsuitable for high risk situation in construction sites. Traditionally, there are 3 excavation methods to frame the soil
retaining piles. Their risk distributions are not similar. Thus, we can’t use the same safety investment budget when we
choose different excavation method. In this study, for increase the exactness of “risk quantity”, we focus on the different
“risk distribution”. Based our risk evaluation of the “hazard uncertainty” concept and introducing the notion of
“opportunity efficiency” to modify usage of the “risk severity” analysis; this concept will increase the accuracy of
safety investment evaluations.
