Load-bearing interior wall

ARC-WALL-INT-LB

Makes load transfer and space separation jointly verifiable early on and provides a reliable basis for structural, fire, and acoustic coordination.

Description

Load-bearing wall between interior spaces according to the structural concept.
Used for coordination with structural engineering, fire and acoustic verification, and component identification.

Modelling guidelines

Model storey by storey; split at component and storey boundaries.
Set IsExternal=FALSE and LoadBearing=TRUE.
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.

FireRating Pset_WallCommon	Fire resistance class of the load-bearing interior wall according to the fire protection concept - load-bearing (R) or load-bearing with integrity and insulation (REI). Allowed values `R 30` - load-bearing 30 min `R 60` - load-bearing 60 min `R 90` - load-bearing 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_WallCommon	Weighted sound reduction index Rw [dB] as laboratory/catalogue value - not R'w.
ThermalTransmittance Pset_WallCommon	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 `C02.02` - interior wall construction
CalculatedType ePset_Cost	Calculated type name for cost and quantity grouping. Logic `WandTypisierung`. Example: `Wand_Innen_Oberirdisch_Beton_200mm_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_WallBaseQuantities.NetSideArea`.

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;`.
