IfcBudget

IfcBudget

Definition from IAI: An IfcBudget represents a cost budget (i.e. an amount of money available from a source) available for projects. This class also allows tracking the history of the budget uses. The details of budget assignment and usage for multiple projects or plans are not handled in this class.

An IfcBudget can be made of other IfcBudget's using the general IfcRelNests relationship to establish a nesting structure.
