Automation of Building Permission by Integration of BIM and Geospatial Data

Abstract

Abstract:The building permission process is to a large extent an analogue process where much information is handled in paper format or as pdf files. With the ongoing digitalisation in society, there is a potential to automate this process by integrating Building Information Models (BIM) of planned buildings and geospatial data to check if a building conforms to the building permission regulations. In this study, an inventory of which regulations in the (Swedish) detailed development plans that can be automatically checked or supported by 3D visualisation was conducted. Then, two of these regulations, the building height and the building footprint area, were studied in detail to find to which extent they can be automatically checked by integration of BIM and geospatial data. In addition, a feasibility study of one visual criterion was conducted. One concern when automating the building permission process is the variability of content within the Industry Foundation Classes (IFC) data model. Variations in modelling methods and model content leads to differences in IFC models' content and structure; these differences complicate automated processes. To facilitate automated processes, requirements on the production of IFC models for building permission applications could be defined in the form of model view definitions or delivery specifications.

Requirements, Development, and Evaluation of A National Building Standard—A Swedish Case Study

“…There is a growing interest to automate the building permit process, as the current process often prolongs the construction time. Information, such as detailed development plans and building permit regulations, are still often handled in paper format or as pdf files [53][54][55]. This can make the process ineffective, both concerning time and cost.…”

“…To enable parts of this rule checking, the BIM-model of the proposed building can be converted to geodata and integrated in a 3D city model. The updated city model is then utilized both for visual inspection as well as in automated routines where the properties of the building and the surrounding environment are tested against rules in a digital detail development plan [55].…”

“…First the detailed development plan, DetailedDevPlan, was imported into FME with a script that was previously created within the project Får Jag Lov? coordinated by Boverket (the National Board of Housing, Building and Planning) (see [55]; FME script available on GitHub: github.com/TestbedLU). The dataset LotsenLOD1GML was imported into FME ( Figure 12a) using a general XML-reader.…”

“…In Sweden the around 270 regulations that can be included in a detailed development plan are listed as codes in a criteria list. Around 85% of these can be automatically checked [55]. As an example, the code DP_KM_S_For (upper regulation in Figure 14) states that the function of a building must be kindergarten (swe: Förskola).…”

Utilizing BIM and GIS for Representation and Visualization of 3D Cadastre

“…Thus, the integration of BIM and 3D city model is mutually beneficial for comprehensive 3D city modelling. The conversion of BIM data to city model data has shown a growing interest in different applications such as urban planning, construction, facilitate management, building permits, and 3D cadastre [36,[41][42][43][44]. Donkers et al [45] addressed conversion from geometry aspects and developed an automatic conversion method from IFC to CityGML LOD3.…”
