Resumen
This study evaluated the BIM Maturity Levels of architecture offices in Porto Alegre (Brazil) by adapting the method developed by Succar [1]. Capacity maturity models, such as the one proposed by Succar [4] identify a set of improvements, of processes that allow implementers to achieve significant business benefits. This methodology proves to be relevant for case studies, as it has the advantage of proposing an assessment of the maturity degree of organizations in the adoption and performance of BIM in its processes, operations and relations with other organizations. To achieve the objectives, theoretical research, case studies and analysis were performed. It was carried out by applying a questionary in face-to-face interviews and converting the qualitative data obtained into quantitative, ultimately generating the BIM Maturity Index: a percentage number that can be classified and compared. For example, with the BIM transition, there was a significant increase of the preliminary design phase, mainly due to the large amount of information that must be provided in the initial modeling stage. This leads to the resolution of a large part of the project in this phase and, consequently, the reduction of the time spent in the? final phases, such as executive project, documentation, budgets and etc., corroborating with the exposed by the MacLeamy Curve, which indicates how BIM workflow works in contrast to the traditional workflow. The results indicate a significant discrepancy in BIM competences between the case studies while reasserting challenges faced by them in a regional scope: the scarcity of external stakeholders appropriately inserted on the BIM process and the undersupplied BIM knowledge offered in academic courses. It is possible to trace similar characteristics and conditions in all case studies.
