Base slab (Rough)

ARC-SLAB-BASE

Rough dimensions according to structural engineering for base slabs in design development and permitting stages.

Description

Coarsely dimensioned base or raft slab according to the structural concept.
Used for coordination between architecture and structural engineering, not for execution planning.

Modelling guidelines

Model as a simplified volume; split at component boundaries.
Do not model reinforcement, foundation details, or layer build-ups.
Early: concept via sketches as structural sketch in the architecture model; verify exclusion zones from the structural engineer.
Later: align the same components with Reference in the structural model as well.
Use an IfcMaterial that corresponds to the actual material class.

Attributes

Name	Description	Unit
ObjectType	Marks the base slab. Allowed values `BASESLAB` - base slab
PredefinedType	Marks the base slab. Allowed values `BASESLAB` - base slab
LoadBearing Pset_SlabCommon	Marks the element as a load-bearing component in the architecture model. Allowed values `TRUE` - load-bearing element
GrossVolume Qto_SlabBaseQuantities	Gross volume of the modelled base slab.	m³
Status Pset_SlabCommon	Element status for coordination on existing buildings. Allowed values `NEW` - new `EXISTING` - existing `DEMOLISH` - to demolish `TEMPORARY` - temporary
ElementStatus ePset_ElementStatus	Element status for coordination on existing buildings. Allowed values `NEW` - new `EXISTING` - existing `DEMOLISH` - to demolish `TEMPORARY` - temporary Note IFC2x3 substitute for Status.
CostInterface ePset_Cost	Cost interface of the component - base building or tenant fit-out. Allowed values `GAB` - base building (client / landlord) `MAB_{Mietername}` - tenant fit-out, e.g. `MAB_Migros`
AwardInterface ePset_Cost	Award package of the component by three-digit BKP code - so interfaces between contractor packages become visible. Allowed values See value list BKP award package - e.g. `211`, `221`, `244`.
PlanningInterface ePset_Cost	Planning interface of the component by three-digit BKP code - so responsibilities between planning disciplines become visible. Allowed values See value list BKP planning package - e.g. `091`, `092`, `094`.
BelowTerrain ePset_Cost	Marks whether the component is below terrain. Allowed values `TRUE` - below terrain `FALSE` - above terrain
EbkpH ePset_Cost	eBKP-H classification according to SN 506 511 - derivable from IsExternal, LoadBearing, and BelowTerrain. Allowed values `C01.03` - base slab
