5. Research: “Ontology based model of underground cables” Management tool and a way to improve the interoperability of multidisciplinary approach toward practical challenges Communication is possible if the model include some kind of common knowledge and the way to share it Actors are surveyor, designer of the project and civil engineer They manage different data and have different roles, perception and responsibilities

6. Research: Ontological modelling of an Archeological project, (archaeologist, European Center in Archeometry) of “Development and use of a 4D GIS to support the conservation of the Calakmul site (Mexico)”. Modelling framework for better communication between actors -aspects of problematic Identification of the problems that are happening in reality -various model Integrate the lonely islands of information and to create a river of information or reality that could connect all data of everyone involved with utilities… -Avoidance of duplication of data and widening of the spatial perception -Improvement of the performance of the utilities during their full life cycle -planning and better decision making during construction phase and afterwards for emergency planning, urban planning and response Single interactive model supporting 3d visualisation communication capability of 3D simulations -Model for a multidisciplinary approach

7. Way how to model it: Important facts: relative depth came before geometry and coordinated in most of the application communication model takes into account implicitly responsibility over the data interconnection of various existing models in order to have a more global view of the impacts of decision-makings at the construction scene multidisciplinary approach is mandatory to perform such models

8. Further research: Communication model Way how to design it Testing the improvement- feeding the improved model with some data (structured as cityGML or IFC or …) and checking if it improves communication between users Ontology as the end of the modelling to reach common understanding between actors 3D models enriched with ontologies

9. Research at TU Delft:  The purpose of the visit is to create model that defines different perception over one object different geometric representations ;  design the information  showing how such information could be obtained (from data structures used by the different users)  Work/study on interactive visualization of underground cables from CAD or IFC data model through CityGML  Investigation of the level of interactivity  Creation of model based on relations among different networks.  Giving an answer on research direction Use of CityGML extension, IMKL New model based on UML/ontologies
