Many developers and building owners feel that regulatory approvals take too much time and effort. This poses a significant delay and risk for building projects. One way to speed up the building permit process is to automate it as much as possible.<\/p>\n
Because 2D PDF files are limited in their capabilities, several governments are developing BIM-based building permits. Regions leading this development include Singapore, the Nordic countries, the UK, Japan, South Korea, and Dubai.<\/p>\n
The trend is to use the open IFC standard<\/a> for model submissions instead of native BIM models. However, the standard has not yet offered universal definitions for automating compliance checking. For example, IFC has had a class for walls (IfcWall) but no standard way to distinguish between specific types of interior walls, e.g., partition walls, fire-rated walls, or sound-insulating walls. This has forced companies or authorities to define custom property sets or user-defined classifications.<\/p>\n At this year\u2019s WDBE summit,<\/a> Tomi Henttinen<\/a> (pictured) presented buildingSMART\u2019s RIR (Regulatory Information Requirements) project, which will improve model machine-readability for regulatory purposes.<\/p>\n Under Tomi\u2019s leadership, the international RIR team focused on four areas:<\/p>\n The process looked at data needed at four regulatory stages: concept approval, technical approval, construction approval, and approval to occupancy.<\/p>\n The RIR project introduced nearly 300 new IFC properties to the IFC standard and almost 200 new Types. These include the definitions for the previously mentioned interior walls, for example.<\/p>\n The project also created a use case<\/a> and a ruleset, the Regulatory Information Delivery Specification (IDS), which you can download.<\/a><\/p>\n Tomi concluded that the RIR project\u2019s results will improve communication between applicants and regulators. Design and model-checking apps can use the new definitions to pre-check designs before they are submitted to authorities. Overall, automation will make building approval more streamlined and faster.<\/p>\n<\/div>\nThe RIR project<\/h3>\n
