In AEC practices multifold digital models exist to support various design and analysis tasks (e.g. architectural or HVAC design, structural or thermal analysis). Information models need to satisfy the particular and varying domain-specific needs. Despite the great efforts to create open standards for data exchange, digital data exchange between domains is still burdened with numerous difficulties, such as loss or wrong interpretation of information. The seamless data exchange between actors in the process would reduce communication-based errors and planning time, and it is a requirement for achieving a full potential of BIM.
This work focuses on the automation of interpretation steps between architectural and structural analysis models with intermediary data available in software independent storage. Previously conducted research identified the need for standardisation of interpretation in order to improve the software-independent data exchange.
Thereby we first review relevant software tools, standards and data exchange processes, where the architectural and structural analysis representations were analysed and the relations between them were identified.
Next, a new framework for data handling in the AEC planning process was created. The data-handling framework is based on domain-specific classification, interpretation and automation procedures that can support interdisciplinary exchange. Classification is needed for systematic arrangement of data in groups or categories according to established criteria, so the data would remain machine readable, and it is based on the IFC taxonomy. Interpretation between architectural and structural analysis models was proposed based on the previously conducted state-of-the-art review. The proposed domain-specific classification and interpretation procedures are developed for the exchange between architecture and structural engineering domains. However, the proposed central data handling framework is generic, so it could be used for other domains in the AEC industry as well. Finally, in the automation procedure, the framework is implemented with the system architecture that can support it. The data is available on a software independent storage, and the domain specific model communicates with the software independent storage. The interpretation is automated with the help of a programming language.
The innovative contribution are primarily the procedural steps defining the interpretation, followed by the proposed framework for the data exchange involving domain-specific classification and interpretation procedures, and finally the automation where a semi-structured database is used for the data storage and interpretations are automated with a programming language. Automating the central storage-based interpretation steps is a crucial feature of a new framework allowing communication between various domain-specific models within software independent storage.
