Risk Assessment Framework to Avoid Serial Failure for New Technical Solutions Applied to the Construction of a CLT Structure Resilient to Climate

Design-build contractors are challenged with the task of minimizing failure risks when introducing new technical solutions or adapting to conditions, e.g., climate change. They seem have a disproportional trust in suppliers and their reference cases might not adequate resources methodologies for sufficient evaluation. This creates potential serial failures spread construction industry. To mitigate this, it was suggested that predefined risk assessment framework should be introduced aim providing prequalification requirements use solution. The objectives this paper develop comprehensive explore framework’s adequately support design-build contractor’s decisions. uses qualitative assessment, relying on expert workshops quantitative assessments, focus simulation probabilities.

In conclusion, chosen successful contractor context, structuring process identifying difficulties achieving functional concerning moisture. Three success factors were: documentation communication, involvement, tollgates. Recommendations CLT structure keep period short full weather protection site.
