Development of building information modelling for dredging process has been studied. In dredging area different 3-D guidance and control systems have been used already over 15 years. However, the information transfer process from early initial data acquirement phase through design and further to construction phase has suffered from information delivery gaps, undetermined modelling and information delivery methods. In the paper, a new specification for initial data modelling, BIM based design process and BIM based as-built measurement and quality control procedures are to be introduced. Most essential in the process model is to transfer the information, which is binding the parties. This will be done electrically using 3D information models throughout the total operation chain. An important result of the project is also the documentation of the current dredging work process in Finland that has not been done in the past. The new models were tested using Novapoint software as a BIM design tool and two different construction projects (Rauma and Helsinki, Finland) were used for the experiments. Future work will be also described.
