Floor slab (Rough)

ARC-SLAB-FLOOR

Defines the load-bearing separation between storeys early and provides design certainty for room heights, structure, and building services.

Description

Coarsely dimensioned floor 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 without layer build-up; split at component boundaries.
Do not model reinforcement, openings, or detail connections.
During conceptual architectural design, coordinate the dimensions of conceptual structural components with the structural engineer and adopt them in the architecture model.
Use and export the appropriate material from the authoring system.

Name	Slab designation according to the structural plan.
PredefinedType	Marks the floor slab. Allowed values `FLOOR` - floor slab
LoadBearing Pset_SlabCommon	Marks the element as a load-bearing component in the architecture model. Allowed values `TRUE` - load-bearing component
Status Pset_SlabCommon	Component status for coordinating work in existing buildings. Allowed values `NEW` - new build `EXISTING` - existing `DEMOLISH` - demolition `TEMPORARY` - temporary
FireRating Pset_SlabCommon	Fire resistance class of the floor slab according to the fire protection concept. Allowed values `R 30` - load-bearing 30 min `R 60` - load-bearing 60 min `R 90` - load-bearing 90 min `EI 30` - integrity and insulation 30 min `EI 60` - integrity and insulation 60 min `EI 90` - integrity and insulation 90 min `REI 30` - load-bearing, integrity and insulation 30 min `REI 60` - load-bearing, integrity and insulation 60 min `REI 90` - load-bearing, integrity and insulation 90 min
AcousticRating Pset_SlabCommon	Weighted sound reduction index Rw [dB] as laboratory/catalogue value - not R'w.
ThermalTransmittance Pset_SlabCommon	Thermal transmittance U [W/(m²·K)] as laboratory/catalogue value of the component.	W/(m²·K)
ElementStatus ePset_ElementStatus	Component status for coordinating work in existing buildings. Allowed values `NEW` - new build `EXISTING` - existing `DEMOLISH` - demolition `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_{TenantName}` - tenant fit-out, e.g. `MAB_TenantA`
FundingApplication ePset_Cost	Number of the funding application, so quantities and costs can be filtered by application. Separate several numbers with commas, e.g. `2024-0142, 2024-0188`. Leave empty when the component belongs to no application.
AwardInterface ePset_Cost	Procurement package of the component, so interfaces between contractor packages become visible. Allowed values See the Procurement package value list. This Swiss data package uses three-digit BKP codes, e.g. `211`, `221`, `244`.
PlanningInterface ePset_Cost	Planning interface of the component as a three-digit BKP code, so responsibilities between design disciplines become visible. Allowed values See the BKP planning package value list, e.g. `091`, `092`, `094`.
BelowTerrain ePset_Cost	Marks whether the component sits below ground level. Allowed values `TRUE` - below ground `FALSE` - above ground
eBKP ePset_Cost	eBKP-H classification according to SN 506 511 - derivable from IsExternal, LoadBearing, and BelowTerrain. Allowed values `C04.01` - floor slab
CalculatedType ePset_Cost	Calculated type name for cost and quantity grouping. Logic `PlattenTypisierung` (Prefix `Decke`). Example: `Decke_Beton_250mm_REI90_53`
ProductClass ePset_Cost	Product class for cost and tender assignment. It may be assigned manually; for consistent tender data, it should preferably be derived from component properties through deterministic automation or AI-assisted mapping. Allowed values See the Product class value list.
UnitPrice ePset_Cost	Project- or office-specific unit price per unit of the reference quantity, used to check component costs for plausibility.	CHF/m²
ReferenceQuantity ePset_Cost	Authoritative reference quantity used with UnitPrice: `Qto_SlabBaseQuantities.GrossArea`.
Connection ePset_Circularity	Connection type for detachability (Madaster). Allowed values `DryConnection` - dry connection `AddedConnection` - connection using added parts `DirectConnection` - direct integral connection `SoftChemicalConnection` - soft chemical connection `HardChemicalConnection` - hard chemical connection
Accessibility ePset_Circularity	Accessibility of the connection without destroying the component or surroundings (Madaster). Allowed values `Accessible` - freely accessible without additional actions `PartialNoDamage` - accessible with actions that cause no damage `PartialWithRepairableDamage` - accessible with fully repairable damage `PartialWithDamage` - accessible with partially repairable damage `NotAccessible` - not accessible; irreparable damage
Reuse ePset_Circularity	Share of already reused or recycled material in the component (0.01 - 1.00, e.g. 0.80 = 80 %).
MaterialOrProductId ePset_Circularity	Unique ID of the material or product in the linked database (e.g. Madaster, baubook).
WasteCodes ePset_Circularity	Waste codes for deconstruction and disposal. Code to VeVA (CH) or EWC/AVV (EU); format as used by Madaster, e.g. `17 01:0.25:Inert:60:60;`.
GlobalTradeItemNumber Pset_ManufacturerTypeInformation	GTIN (Global Trade Item Number) of the product type; 8, 12, 13, or 14 digits depending on the GS1 structure.
HazardType ePset_HazardousMaterial	Type of hazardous material found by survey on the affected existing component. Allowed values `Asbestos` - asbestos `PCB` - PCB `PAH` - PAH `PCP` - PCP `Lead` - lead `None` - no hazardous material `Unknown` - unknown / not investigated
RemovalCategory ePset_HazardousMaterial	Remediation urgency and action required, as determined by the survey. Allowed values `Immediate` - remediate immediately `PriorToDemolition` - remediate before demolition or alteration `InSitu` - may remain in place, under monitoring `None` - no action required
SerialNumber Pset_ManufacturerOccurrence	Serial number the manufacturer assigns to an individual product; with the GTIN it identifies the product passport for that specific item.
Width Qto_SlabBaseQuantities	Thickness of the modelled slab.	m
