The reusability of informative content throughout the building life cycle is a current issue in the AEC sector.

Abstract

The reusability of informative content throughout the building life cycle is a current issue in the AEC sector. One of the cornerstones of BIM is to guarantee the availability and portability of data which, against a greater initial investment for the construction of the model, will offer a multidisciplinary and integrated tool to support all possible operations on the building. The issue becomes even more complicated in the case of cultural heritage or existing structures where the information process starts directly from the operation stage (management and maintenance phases) and provides, through reverse engineering methodology, an Asset Information Model. It is therefore essential to keep track of the levels of accuracy of this content, in relation to the geometric and informative attributes of all the objects that make up the model. Starting from a careful analysis of the state of the art related to these issues, this paper proposes a possible approach to the statistical treatment of uncertainties related to geometric attributes in case of Historic or Existing BIM, differentiating between the products of the survey and those of the subsequent parametric modelling.
