Estudo da compatibilização de projetos pelo método tradicional e com uso de BIM

Abstract

All civil construction endeavors begin at the design stage, from which crucial information is obtained to plan and budget the works. Incompatibilities between the projects of the disciplines involved are recurrent and directly interfere with the execution of the work if they are not resolved previously, however, making them compatible demands time and technical knowledge from different disciplines. With technological advances, the potential of Building Information Modeling – or construction information modeling (BIM) – to make compatibility more agile and rapid can be seen, in addition to, mainly, mitigating conflicts between projects through interoperability. Given this context, this work aims to present the process of project compatibility using the traditional method and using BIM. As specific objectives, look for the main incompatibilities and difficulties in implementing BIM for compatibility. To this end, a case study was carried out in which an author participated in the compatibility of two adjacent works with simultaneous execution, the first made compatible using the traditional method with overlapping 2D CAD drawings and the second using BIM. For the latter, a federated model created for three disciplines in Revit 2023 was exported to Navisworks Manage 2023, the BIM interface software chosen after carrying out comparative research between the three most widespread nationally for compatibility. For theoretical foundation, a simplified systematic mapping of the literature was carried out. Of the main results, making compatible using the traditional method in contrast to applying BIM for the same activity attest to the use of BIM as superior to the traditional method, highlighting the savings of at least 50% of the time spent and a number of conflicts detected 41 times higher . The level of updating of the company's BIM was also noted, justified by a cultural problem to be overcome, as only 33% of the projects contracted for the works were originally developed in BIM and to the detriment of the unavailability of skilled labor for hiring.
