| Abstract: | Collection, management and use of information is considered one of the most important aspects within the built environment management. While projects in the construction industry are becoming more challenging and complex with many disciplines involved in, efficient exchange and use of information among domain professionals is fundamental for successful results. This requirement is even more evident during preliminary phases, which are decisive for the outcomes of subsequent phases of the lifecycle. The introduction of Building Information Modelling (BIM) has been one of the most significant efforts concerning data management within the built environment. BIM, which advocates the consistent and continuous use and re-use of data in digital format throughout the entire lifecycle of a built facility, has improved information flows between stakeholders thus resulting better communication and collaboration. Nevertheless, it can be observed that despite its advantages, BIM practices are not really used in early design phases. The main reason is that current structures do not address early design phase information requirements while at the same time a common language to exchange information is absent. Shared 3D objects and models are the foundation of BIM implementation strategies, whereas not all disciplines of early phases are working in an object-based way. Additionally, in early design there are no 3D models that are needed to share and reuse data. Consequently, professionals are unable to work in a shared way using centralized data. Hence, they collect and manipulate information in isolated platforms. This practice hinders the seamless flow of information between project members and various design stages and leads to information loss. Given that context, this research intends to develop a framework and a workflow for structuring information in the early stages of a project, in such a way that project members can efficiently and consistently work with centralized data and later integrate them seamlessly into the final design phase. The engineering company ABT bv provides the context of this study. The scope covers the Early Design stages and part of the initiation of the Final Design. Moreover, in order to include a considerable part of building data six disciplines of ABT are taken into consideration namely, cost estimation, building physics, sustainability assessment, fire safety, architectural and structural engineering departments. In order to address the main research objective, the conceptual part of the research proposes an ontology that enables information integration among different disciplines during the early design stages and later on facilitates the information flow towards the final design. The proposed ontology results from the enrichment of the current IFC schema with additional concepts that particularly address the needs of preliminary phases. Furthermore, a novel workflow around this ontology is established. During the development phase, the findings of the previous step are implemented in a case study project. For that reason a working prototype tool is developed, which is a demonstration of how the ontology can be used in practice. The evaluation outcomes indicate that the proposed ontology has the potential to contribute towards an efficient and consistent use of centralized data during the early design stages. At the same time, it can enable a smooth incorporation of information in later design stages. Overall, this study concludes that BIM without a 3D and a new way of working based on centralized information in preliminary phases of the lifecycle can be accomplished. |
