Ambiguous set of classifications for common MEP items #192

Open Moult opened 2 years ago

Moult commented 2 years ago

In 2019 (and still now :) ) i did a lot of work going through models object by object checking their IFC classification. I found many objects I was unsure where they would belong. I made a list here of the objects I would find in a lot of models. Due to their commonplaceness, I would assume IFC should cover them. For example fire extinguisher.

List here

Edit: I've just tabulated them here.

Thing IFC Class
Electric strike IfcActuator.WHAT?
Intermediate distribution frame IDF IfcElectricDistributionBoard.WHAT?
Panic button IfcAlarm.WHAT? IfcSwitchingDevice.MOMENTARYSWITCH ?
Reed switch IfcSwitchingDevice.CONTACTOR ? IfcSensor?
Egress paths IfcBuildingElementProxy.PROVISIONFORSPACE
Load bank ?
Fire hydrant booster IfcCompressor.BOOSTER? IfcPump?
Air pressure maintenance device ?
Pipe sight glasses IfcDistributionChamberElement.WHAT?
Pipe clamps IfcDiscreteAccessory.WHAT?
Tundish IfcWasteTerminal.WHAT?
Vent cowl IfcStackTerminal.COWL?
Rainwater outlet filter cover IfcFilter.?
UV disinfection system IfcFilter.?
VAV box IfcAirTerminalBox.VARIABLEFLOWPRESSUREDEPENDANT or VARIABLEFLOWPRESSUREINDEPENDANT
Ceiling access panels IfcDoor? IfcCovering.CEILING?
ATM Machines ?
Ticketing machines ?
Signage IfcSign
Fire extinguisher IfcFireSuppressionTerminal.WHAT?
Swimming pool filter IfcFilter.WATERFILTER
Pool bottom drain ?
Skimmer ?
Pool return device ?
Pool suction device ?
Pool whirlpool device ?

Can we go through this list and figure out where they belong and whether or not any enums can / should be added?

Ping @CyrilWaechter as many of these are MEP things.

Hello everybody. Hi Dion,
