Summary, in English

The management of construction tolerances is a necessary and routine part of the construction activity and is normally brought to our attention only when failures are reported. In a study of tolerance management, the authors found widespread evidence of the same failures and the reasons for them. There seems to be no shortage of experience of the effects of failures in tolerances or of knowledge about how to avoid them. The situation is frustrating for all involved, especially the owner, end-users, designers and operatives. In questioning practitioner experts in this field, the authors identified a misalignment in the perception of ‘problem, cause and effect’. In workshops involving experts from various construction backgrounds, the issue of tolerance management and, in particular, failures and their causes were examined. The experts were introduced to the concept of fault diagnosis using backwards-chaining ‘cause and effect’ analysis. Experts were then asked to undertake several analyses of their own of preselected failures using a cognitive mapping tool. The purpose of the study is to see how useful the method is among the experts and later be able to identify the root causes to the issues of tolerance management. The preliminary results showed that the experts were initially reluctant to break with discussing the effects and what they saw as the solutions, but gradually began to trace the causes backwards until they believed they had identified the root causes. The results show a possibility to reach beyond the obvious problems and therefore as a consequence be able to find a new approach in the following steps of the research process. This is a proven working method for research problems where the interaction with partners in the industry is of great importance.
