BIM och informationsöverföring - En studie om IFC-baserad teknik i förvaltningsskedet

Sammanfattning: Building information modelling, BIM, is a well-known and established conception within the construction business. In the building industry BIM technology is used as a tool and a work method by different occupational groups within planning, production and facility management. Due to the usage of BIM differs between the fields, so does the software’s as well. The software’s are using different types of file-formats causing a gap in the information flow between the programs. Meaning, there is a chance for information being lost when switching between different software’s. BIM therefore loses a part of its purpose if the different software’s cannot collaborate. A solution to the problem is to use an open, international and standardized file format, IFC, to make it possible to exchange and share data among the different software’s. There are mixed opinions on the reliability of IFC which will be investigated further in this bachelor thesis. The purpose of this bachelor thesis, is to review the information flow between different software’s. The matter being studied is the IFC and Fi2xml export and import in the following software’s: Autodesk Revit Architecture, Solibri Model Viewer and FME. The information being reviewed is the one created during the planning and are required by facility managers. In this bachelor thesis, literature and previous studies has been reviewed to form the basis of the interviews and simulations leading to the result. The interviews were conducted with facility managers to find out what information is required in the business. Consultants from various professions in IT, BIM and information coordination has contributed with their expertise knowledge that has formed the basis of the simulations performed. The stimulations has been conducted on models from offices spaces under reconstruction (Västgötagatan 5) and the research center ESS in Lund were the BIM technology has been paying an important role in the project. The result shows that the information that facility managers are asking for is information about area. The result imply that IFC have some weaknesses but when it comes to the information, as area and surface area etc. that facility managers are asking for there isn’t any significant problem and the information presides well.
