Interior spaces

SPACE-INT

Enclosed, walkable room volumes within the building.

Description

Usable interior spaces modelled as continuous volumes.
Room use is carried in LongName; Name may carry the room number.

Modelling guidelines

Model as a volume with the space tool, storey by storey.
From top of finished floor to underside of the structural ceiling - not a suspended ceiling. Only then can the space be reused by other trades.
No overlaps or duplicates.

Attributes

Name	Description	Unit
PredefinedType	Marks the space as interior. Allowed values `INTERNAL` - interior space
InteriorOrExteriorSpace	Marks the space as interior. Allowed values `INTERNAL` - interior space Note IFC2x3 substitute for PredefinedType and IsExternal.
LongName	Normalized room use for interior spaces according to Pragmatic BIM Building Space Name Classification v0.2.0. Source https://schema.pragmaticbim.ch/classification/room-name.html Allowed values See value list Room name interior space v0.2.0 - RN notation.
Name	Unique technical room number for planning. It should stay stable as long as: the room size does not change substantially (e.g. from 12 m² office to 25 m² open-plan office) the function does not change substantially (e.g. from office to meeting room) and the orientation does not change (e.g. from south to east facing) Do not use for signage - signage room numbers change often and belong in SignageRoomNumber.
SignageRoomNumber ePset_SpaceSignage	Room number for wayfinding signage (labelling, orientation). Separate from the technical planning room number (Name), because signage numbers often change and frequently differ from the planning number.
Reference Pset_SpaceCommon	Area class of the space according to SIA 416 or SIA D0165. Source SIA 416: https://schema.pragmaticbim.ch/classification/mapping-room-activity-to-sia416.html SIA D0165: https://schema.pragmaticbim.ch/classification/mapping-room-activity-to-d0165.html Allowed values See value list Space reference interior SIA 416 / D0165 - e.g. `HNF`, `NNF`, `VF` (SIA 416) or `HNF-1`, `NNF-7`, `VF-9` (D0165).
IsExternal Pset_SpaceCommon	Marks an interior space. Allowed values `FALSE` - interior space
NetFloorArea Qto_SpaceBaseQuantities	Net floor area of the modelled space.	m²
NetVolume Qto_SpaceBaseQuantities	Net volume of the modelled space.	m³
Height Qto_SpaceBaseQuantities	Height of the modelled space volume.	m
FinishCeilingHeight Qto_SpaceBaseQuantities	Suspended ceiling height - clear height from top of finished floor to underside of the suspended ceiling. Note For an uneven suspended ceiling, pick the worst case for use: the deepest underside (smallest clear height).	m
FloorCovering Pset_SpaceCoveringRequirements	Floor covering type for early planning - as a space property only, without a modelled floor build-up. Allowed values See value list Space floor covering type.
DesignAreaLoad ePset_SpaceUsageAgreement	Agreed design area load for the usage agreement (SIA 260).	kN/m²
DesignPointLoad ePset_SpaceUsageAgreement	Agreed design point load for the usage agreement (SIA 260).	kN
VibrationRequirements ePset_SpaceUsageAgreement	Agreed vibration requirements for the usage agreement (SIA 260) as Vibration Criterion (VC). Allowed values See value list Vibration criterion VC.
Checkliste ePset_SpaceFitOut	Free-text description of fit-out work in the room including sequence - so contractors on site can see what needs to be done.
