AbstractThe increasing application of BIM processes and technologies has facilitated an increase in the use of 4D (3D+Time) simulations of construction projects. Numerous studies have acknowledged the benefit of 4D models in project planning and construction phases, enhancing communication between construction teams and avoiding unforeseen conflicts during the build process. The development of BIM has prompted a deeper understanding of the issue surrounding Level of Development (LODt), Level of Information (LOI) and Level of Detail (LOD) relating to the graphical detail and non-graphical information of the static geometric design model. However, up to now there is limited research methodically investigating the issue of LOD within 4D BIM applications. This research aims to develop a framework for specifying the LOD of 4D BIM to enhance communication and planning at various stages of the construction process. A 4D simulation needs more dynamic elements to alter the current 4D static image in order to provide more realistic simulation and more accurate results. A mixed research methods approach was developed to address the needs for successful framework development. A combination quantitative and qualitative survey was undertaken to gather data from professionals engaged in the development of 4D BIM simulations on construction projects. A framework was developed to provide professionals with an approach to develop LOD for 4D simulations (LOD4d) and following this the framework was validated through qualitative interview with experts in the field. The uniqueness of the work required the invention of new terminology. The developed framework incorporates terms for Level of Graphical Detail (LODg) the graphical information of the model. Level of Detail of object geometry “granulated” (LODgran) into segments showing how the object was constructed over the time. The framework comprises a time period required between state changes in the model during the simulation which is Temporal Level of Detail (LODti). The outcome of the work is the generation of a framework which supports the development of 4D simulations at a range of LOD. This can then be utilised as part of the BIM process to support the generation of 4D simulations at levels of detail suitable to the operations being undertaken. This could then lead to the development of an additional protocol within the BIM suite. Beside the construction industry specialists have provided suggestions to further support approach of communication during the construction process.
