IfcCostValue

IfcCostValue

实体定义

IfcCostValue是一个金额或影响金额的值。

IfcCostValue的每个实例也可能有一个类别。可以识别出许多可能类型的成本价值。虽然人们对可能分配给不同类型成本的名称的含义有着广泛的理解，但对成本类型的命名没有通用标准，也没有任何广义的分类。

以下定义了一些可能应用于“类别”属性的成本类别：

 

• 年收益率
• 奖金
• 批量采购折扣
• 合同
• 咨询
• 传送
• 估计成本
• 租用
• 安装
• 利率
• 劳动
• 租赁
• 标价
• 维修
• 布料
• 开销
• 邮寄和包装
• 利润
• 购买
• 租金
• 修理
• 替换
• 出售
• 少量附加费
• 备件
• 存储
• 分包合同
• 贸易折扣
• 运输
• 废弃物津贴
• 全生命周期

 

注：在没有任何明确定义的标准的情况下，建议制定当地协议，以定义项目或地区内允许和可理解的成本价值类型。

Attribute inheritance

#	Attribute	Type	Cardinality	Description	C
IfcAppliedValue
1	Name	IfcLabel	[0:1]	A name or additional clarification given to a cost value.	X
2	Description	IfcText	[0:1]	The description that may apply additional information about a cost value.	X
3	AppliedValue	IfcAppliedValueSelect	[0:1]	The extent or quantity or amount of an applied value.	X
4	UnitBasis	IfcMeasureWithUnit	[0:1]	The number and unit of measure on which the unit cost is based. Note: As well as the normally expected units of measure such as length, area, volume etc., costs may be based on units of measure which need to be defined e.g. sack, drum, pallet, item etc. Unit costs may be based on quantities greater (or lesser) than a unitary value of the basis measure. For instance, timber may have a unit cost rate per X meters where X > 1; similarly for cable, piping and many other items. The basis number may be either an integer or a real value. Note: This attribute should be asserted for all circumstances where the cost to be applied is per unit quantity. It may be asserted even for circumstances where an item price is used, in which case the unit cost basis should be by item (or equivalent definition).	X
5	ApplicableDate	IfcDate	[0:1]	The date on or from which an applied value is applicable.	X
6	FixedUntilDate	IfcDate	[0:1]	The date until which applied value is applicable.	X
7	Category	IfcLabel	[0:1]	Specification of the type of cost used. NOTE  There are many possible types of cost value that may be identified. Whilst there is a broad understanding of the meaning of names that may be assigned to different types of costs, there is no general standard for naming cost types nor are there any broadly defined classifications. To allow for any type of cost value, the IfcLabel datatype is assigned. In the absence of any well defined standard, it is recommended that local agreements should be made to define allowable and understandable cost value types within a project or region.	X
8	Condition	IfcLabel	[0:1]	The condition under which a cost value applies. For example, within the context of a bid submission, this may refer to an option that may or may not be elected.	X
9	ArithmeticOperator	IfcArithmeticOperatorEnum	[0:1]	The arithmetic operator applied to component values.	X
10	Components	IfcAppliedValue	L[1:?]	Optional component values from which AppliedValue is calculated.	X
	HasExternalReference	IfcExternalReferenceRelationship @RelatedResourceObjects	S[0:?]	Reference to an external reference, e.g. library, classification, or document information, that is associated to the IfcAppliedValue.	X
