Quick assessment tool for assurance of structural safety in the building process

From forensic investigation it is known that many structural failures can be attributed to human errors and organizational factors. To provide project leaders with information on the current state of factors in the building process influencing structural safety, we developed a quick assessment tool. Logistic regression was used, based on data of influencing factors from a national questionnaire, to derive a function that predicts the probability of a successful outcome, regarding structural safety. The results show that a function with only the factors collaboration, risk analysis and control could predict a successful project correctly in 85% of cases, with collaboration as most determining factor. Although this method has limitations, it gives a quick indication of the degree in which problems regarding structural safety are to be expected. We believe that this tool has the potential to develop into a risk management tool.
