In the current digital era, a construction filed becoming more complex and cost-effective we have ever seen before, due to fact that innovative methodologies and information technologies such as Building Information Modelling are developing rapidly. Any contraction design project involves different disciplines like structural, architectural, mechanical, electrical etc. A coordination between them is most important requirement, to achieving this aim a BIM methodology is a key. This thesis aims at enhancing comprehension of mono-disciplined BIM model by means performing clash detection. As a case study parking area of the Piedmont Region Service Centre building research project were considered. Starting from an existing structural and architectural model of parking area of the building an electrical BIM model was created to perform clash detection of between firefighting and electrical systems.
