1. Maintenance Management of Existing Building Supported on BIM

The management of building maintenance has changed significantly since the advent of Building Information Modelling (BIM) in architecture, engineering, construction, and operations. However, developing and managing predictive maintenance plans that rely on software remains a difficult and time-consuming task. Therefore, the objective of this work is to demonstrate the advantages of the BIM method for maintaining the condition of buildings during their life cycle. To this end, the methodology developed aims to implement the BIM method in maintenance management by exploring the interoperability between the Revit software and the Excel database, which allows the synchronisation of preventive maintenance plans between these two platforms. The methodology developed and applied to a case study consists of modelling the case study in Revit and introducing the corresponding parametric information. Then, Table 13 of the Omniclass standard was applied, which classifies spaces according to their use. Then, a maintenance plan was developed for some elements of the case study. Finally, a bidirectional interaction between Revit and Excel was established through a Dynamo routine for Revit and through a commercial add-in. This work demonstrates a method to avoid fragmentation of information during the life cycle of a building. This allows for efficient management and thus cost reduction in future interventions. This work summarises all building information in a unified model and aims to develop a methodology that can be applied to other building typologies.
