6.4.4.16.1 Semantic definition

A property agreement is an agreement that enables the occupation of a property for a period of time.

The objective is to capture the information within an agreement that is relevant to a facilities manager. Design and construction information associated with the property is not considered. A property agreement may be applied to an instance of IfcSpatialStructureElement including to compositions defined through the IfcSpatialStructureElement.Element.CompositionEnum.

Note that the associated actors are captured by the IfcOccupant class.
