Use Definitions

Actor attributes such as the organization to which the order is sent, issuing organization, person responsible atc. are handled by assigning instances of IfcActor through IfcRelAssignsToProjectOrder. The IfcActorRole must be asserted with the value of the role set when used in this context.

A work plan (acting as a service) may be assigned to a project order (acting as a client) to describe how the project order should be fulfilled. This is handled by assigning instances of IfcWorkPlan through IfcRelAssignsToProjectOrder.

The reverse of this situation may be true whereby the work plan (acting as a client) may have project orders (acting as a service). This is handled by assigning instances of IfcProjectOrder to an IfcWorkPlan through IfcRelAssignsToControl.

Approvals including signoff, authorization etc. are handled using the the IfcRelAssociatesApproval relationship class.

A cost schedule may be assigned to a project order are handled through the IfcRelAssignsToProjectOrder relationship.
