In AEC world, there is several laws and rules to control the building design, structure design and MEP design. Headroom is one of the common rule that control the emergency routes or the car parking routes of the building. In this blogger, I would like to share and useful tools which can check the headroom of building refer to the model.
Introduction of Solibri
Solibri is an open bim software which accept the IFC format. Base on some man-made ruleset, it help to check the quality of the imported model. The common usage is use to check headroom, width of access, distance between pipes, clash of elements, etc.
Workflow of checking headroom
1. Export IFC file from BIM software
From the effort of openBIM company, most of the BIM software can export IFC file. Besides use Solibri,. please ensure the coordination system and export. For example, Revit can export IFC 2.3 to IFC 4.0 base on share coordinates. Also, if different headroom checking is need for different room. Please group the related room and export IFC separately.
2. Create different rule sets base on requirements. In general, I will check the headroom between floor below vs beam, floor, ceiling above first. The minimum headroom is 2000mm. Then I will check the stair case headroom which always fail after construction. The minimum headroom will set as 2050mm while there are plastering words and defection after construction. 50mm is use to adopted the Torrance.
