For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector’s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process. The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities. One step towards BIM is the use of their visualization software Novapoint Virtual Map in a better way. They lack a good system to show which pipes belongs to different documents, i.e. some kind of status management. Another step towards BIM is to be able to change and revise Water and Sewage 3D-models with HVAC 3D-models, and to be able to detect possible errors in the connection nodes early in the designing stage. In this thesis work, a CAD-model has been created in Novapoint VA, the CAD software used to design pipe and sewage systems at WSP. The designed model is divided into many stages which creates many parallel documents at the same time. The model is visualized in Novapoint Virtual Map where functions for status management are created. With the help of grouping functions in the software it is possible to show pipes that belong to different documents at the same time. The more documents there are in the same model the longer it takes to create the model, which is something that could be improved in later editions of the software. In this paper, seven tests were carried on to examine how water and sewage pipes CAD-models created in Novapoint VA can be jointly revised with HVAC CAD-models created in MagiCAD. The result of the test shows that four of these tests can be used to revise the models. To use one of these methods, according to the BIM model, for changes and revisions of models can help avoid mistakes in connection points already at design stage.
