IfcRailing.PredefinedType #13

Open RickBrice opened 4 months ago

In the IFC mapping spreadsheet, the predefined type of IfcRailing is GUARDRAIL. I wonder if it should be BALUSTRADE.

https://standards.buildingsmart.org/IFC/RELEASE/IFC4_3/HTML/lexical/IfcRailingTypeEnum.htm

BALUSTRADE Guardrail located at the edge of a floor, rather then a stair or ramp. Examples are balustrades at roof-tops or balconies, or along a bridge or on top of a retaining wall.

GUARDRAIL A type of railing designed to guard human or vehicle occupants from falling off a stair, ramp or landing where there is a vertical drop at the edge of such floors/landings, or to provide restraint to an errant road vehicle, installed on the central reserve of or alongside a road.

lt seems GUARDRAIL is more appropriately used to defined roadside railing, not on a bridge.

So, the opposite of the American Heritage and Webster’s dictionaries… oh boy.

From https://www.merriam-webster.com/dictionary/balustrade

balustrade - a row of balusters topped by a rail image

It could also be IfcWall.PredefinedType = PARAPET

A wall-like barrier to protect human or vehicle from falling, or to prevent the spread of fires. Often designed at the edge of balconies, terraces or roofs, or along edges of bridges.
