Integration of Lean Con. and Building Information Modelling

subcontractors ­ agreeing to use the same primary BIM tool. Data exchange between these partners was thus reduced to a question of data synchronization, which is discussed later in this case study. Nevertheless, data also had to be exchanged with other applications, such as Trimble Realworks, Vico Control, PERICad, Reinforcement List v3.1 and fabricators' ERP systems. Where this required only geometry exchange, such as between TrimbleWorks and the Tekla model, the DWG file format was used. Where richer information exchange was needed, such as between the Tekla Model and PERICad, IFC files were used. Where alphanumeric data sufficed, or where geometry could be described parametrically rather than explicitly, such as for defining rebar shapes for fabrication, simple ASCII file formats were generated from the Tekla model. These exchanges are shown in figure 9.8.5.
