IfcConstructionMaterialResource identifies a material resource type in a construction project.
HISTORY New entity in IFC2.0.
IFC4 CHANGE The attribute Suppliers has been deleted; use IfcRelAssignsToResource to assign an IfcActor to fulfill the role as a supplier. The attribute UsageRatio has been deleted; use BaseQuantityConsumed and BaseQuantityProduced to indicate material usage.
Occurrences of IfcConstructionMaterialResource are consumed (wholly or partially), or occupied during a construction work task (IfcTask).
Similar to IfcConstructionProductResource, sometimes things such as 5000kg of gravel are already instantiated as an instance of an IfcProduct subtype because it is a result of a work task (for example, ‘transporting gravel’). In this case, the instance of IfcConstructionMaterialResource can be associated with the product instance ‘5000kg of gravel’ to provide more information for resource uses. Nevertheless, IfcConstructionMaterialResource should only be used to represent resource usage, but not product substances.
NOTE This entity is not the same as IfcMaterial. One one hand, IfcConstructionMaterialResource represents usage of bulk materials such as sand, gravels, nails and so on. Physical manifestations can be instantiated from IfcProduct as well, depending on their uses in the system, and such an IfcProduct object can be assigned to the IfcConstructionMaterialResource object via IfcRelAssignsToResource. On the other hand, IfcMaterial is about physical materials that a physical building element consists of, possibly with detailed material layering information."

| IfcObject | |||||
| 5 | ObjectType | IfcLabel | ? |
The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute PredefinedType is set to USERDEFINED.
| X |
| IsDeclaredBy | IfcRelDefinesByObject @RelatedObjects | S[0:1] | Link to the relationship object pointing to the declaring object that provides the object definitions for this object occurrence. The declaring object has to be part of an object type decomposition. The associated IfcObject, or its subtypes, contains the specific information (as part of a type, or style, definition), that is common to all reflected instances of the declaring IfcObject, or its subtypes.
IFC4 CHANGE New inverse relationship, change made with upward compatibility for file based exchange. | X | |
| Declares | IfcRelDefinesByObject @RelatingObject | S[0:?] | Link to the relationship object pointing to the reflected object(s) that receives the object definitions. The reflected object has to be part of an object occurrence decomposition. The associated IfcObject, or its subtypes, provides the specific information (as part of a type, or style, definition), that is common to all reflected instances of the declaring IfcObject, or its subtypes.
IFC4 CHANGE New inverse relationship, change made with upward compatibility for file based exchange. | X | |
| IsTypedBy | IfcRelDefinesByType @RelatedObjects | S[0:1] | Set of relationships to the object type that provides the type definitions for this object occurrence. The then associated IfcTypeObject, or its subtypes, contains the specific information (or type, or style), that is common to all instances of IfcObject, or its subtypes, referring to the same type.
IFC4 CHANGE New inverse relationship, the link to IfcRelDefinesByType had previously be included in the inverse relationship IfcRelDefines. Change made with upward compatibility for file based exchange. | X | |
| IsDefinedBy | IfcRelDefinesByProperties @RelatedObjects | S[0:?] | Set of relationships to property set definitions attached to this object. Those statically or dynamically defined properties contain alphanumeric information content that further defines the object.
IFC4 CHANGE The data type has been changed from IfcRelDefines to IfcRelDefinesByProperties with upward compatibility for file based exchange. | X | |
| IfcResource | |||||
| 6 | Identification | IfcIdentifier | ? |
An identifying designation given to a resource.
It is the identifier at the occurrence level.
IFC4 CHANGE Attribute promoted from subtype IfcConstructionResource. | X |
| 7 | LongDescription | IfcText | ? |
A detailed description of the resource (e.g. the skillset for a labor resource).
IFC4 CHANGE The attribute LongDescription is added replacing the ResourceGroup attribute at subtype IfcConstructionResource. | X |
| ResourceOf | IfcRelAssignsToResource @RelatingResource | S[0:?] | Set of relationships to other objects, e.g. products, processes, controls, resources or actors, for which this resource object is a resource. | X | |
| IfcConstructionResource | |||||
| 8 | Usage | IfcResourceTime | ? |
Indicates the work, usage, and times scheduled and completed. Some attributes on this object may have associated constraints or time series; see documentation of IfcResourceTime for specific usage. If the resource is nested, then certain values may be calculated based on the component resources as indicated at IfcResourceTime.
IFC4 CHANGE New attribute. | X |
| 9 | BaseCosts | IfcAppliedValue | ? L[1:?] |
Indicates the unit costs for which accrued amounts should be calculated. Such unit costs may be split into Name designations (for example, 'Standard', 'Overtime'), and may contain a hierarchy of cost values that apply at different dates (using IfcCostValue.ApplicableDate and IfcCostValue.FixedUntilDate).
IFC4 CHANGE New attribute. | X |
| 10 | BaseQuantity | IfcPhysicalQuantity | ? |
Identifies the base quantity consumed of the resource relative to assignments.
For crew, labour, subcontract, and equipment resources, this refers to IfcQuantityTime.
For material resources, this refers to IfcQuantityVolume.
For product resources, this refers to IfcQuantityCount.
