BIM model content checking: short and long term strategies for large building portfolio owners

Companies define modelling methodology via Building Information Modelling (BIM) protocols. BIM modelling protocols are detailed and documented methods of model production, exchange, and delivery (i.e., a set of modelling step, methodologies and, workflows). Validate and check the compliance between BIM models and modelling protocols is crucial to ensure deliverables are according to expected outcomes. Validation refers to the process of checking models for incompatibility with the defined modelling specifications. Model checking can be a manual or an automated task. The study describes, in the context of a real case study, a model content checking procedure and proposes a comparative analysis between a manual and an automated validation, quantifying the differences in terms of effectiveness and efficiency. Data about time and extent of the two different checking processes are provided. The study aims to identify and measure advantages and limitations of the two procedures in a short- and long-term scenario.
