Integration of Lean Con. and Building Information Modelling
The first and most obvious way in which this was
tackled in the Crusell Bridge project was by all major participants client, designers, general contractor and major
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
