IFCPROCESSEXTENSION
The data model consists of the following:
Introduction
The IfcProcessExtension schema provides the primary information
that expands one of the key ideas of the IFC Model. This is the idea of
'process' which captures ideas about the planning and scheduling of work and
the tasks and procedures required for its completion. It is important to
understand that process information can be expressed by classes in exactly the
same way as product information. A process can also have state and identity,
the state being determined by the values of various attributes of the
processes.
Scope
The IfcProcessExtension schema extends the primary idea of the
IfcProcess outlined in the IfcKernel schema. The objective of the
IfcProcessExtension schema is to capture information that supports the
planning and scheduling of work and the procedures and resources required to
carry out work. The aim is to provide support for information exchange and
sharing within commonly used scheduling applications; the extent of the model
will not support the more detailed ideas found in more specialized scheduling
applications.
The following are within the scope of this part of the
specifications:
- definition of work plans including the tasks that are included within
the plan and identification of the resources required by the plan,
- definition of work schedules together with the elements that make up
the schedule, the time constraints and durations applicable to the
elements,
- identification of work tasks included in plans and schedules,
- identification of procedures that are considered to not consume time
in their accomplishment,
- identification of the relationship between a process and the
resources that are consumed by the process,
- allocation of resources to work plans, work schedules and work
tasks.
