Unbroken Digital Data Flow In The Built Environment Process : A Case Study In Sweden
Author
Summary, in English
An unbroken digital data flow would save substantial resources in the built environment process. In this study, which is part of a larger Swedish project, data delivery specifications and methods to integrate BIM and geodata are developed and tested with the aim to facilitate such an unbroken data flow. The main focus areas of the study are: (1) specifications that enables building permission applications based on BIM data to automate the building permission process, (2) reuse of as-built BIM models to update geodata when a building is constructed and (3) a national Swedish CityGML ADE for buildings. The study shows that building permission applications can be partly automated even though the delivery specifications were in the early stages of development at the time of a performed test case. With fully implemented delivery specifications more regulations can be checked. Furthermore, the study demonstrates how a BIM model can be georeferenced with a standard deviation of the transformation of 3 cm compared to field measurements performed with a total station. The georeferenced BIM model can then be converted to a LOD2 geodata building model to update existing geodata. Finally, a proposal for a national Swedish CityGML ADE for buildings is presented.
