BIM interoperability in the maintenance planning process for existing buildings

Abstract

One of the main di culties inherent to the process of maintenance and management of existing assets is the lack of plans and project documents that allow a study and even an understanding of how the structure of the building works, in addition to the lack of records of the changes made that may have altered the structure of the heritage building over time. This makes it di cult to analyze interventions to treat possible problems that may evolve to more worrying pathologies and that put at risk the useful life of the property. Older buildings require more frequent inspections to carry out interventions that can extend their service life. Having all records of maintenance and inspections carried out is essential for better planning of future interventions. This work aims to develop a work ow methodology to facilitate the process of maintenance and management of existing buildings, uniting facility management concepts and using BIM interoperability, through IFC (Industry Foundation Classes), integrated with online forms for collection and documentation of visual inspection data of the structure. To perform this dialogue, the Software Navisworks Manage 2022 was used for the visualization and documentation of the 3D model referring to the as-built of the SG-12, part of the set of General Services Sheds of the University of Brasília, which besides being an old building and being in the process of being listed as cultural heritage, has undergone several changes over time. The methodology developed and the result of the documentation of the data are presented in detail.

“…Models of building structures, engineering pipelines, architectural details are usually developed by different groups of designers using different software. For the integrated digital model to contain relevant information updated in furtherance of changes made in one of its sections, the interoperability of all models, containing information about structural and other solutions, is needed [23,24].…”
