About Disciplines, System Classes and Service Types

Disciplines

Disciplines are the highest organizational elements in the program structure: examples are heating, cooling, waste water, potable water, ventilation or void planning.

Disciplines fulfill the following tasks:

• provision of the appropriate functions in the construction tab
• provision of the appropriate views in the project tab
• provision of the appropriate system classes in the construction tab
• provision of the appropriate libraries in the library tab
• Visibility control for pipes, ducts, cable trays, conduits, components and architecture in the model

System classes

System classes serve to classify pipes, ducts and components. Examples are supply, return, cold water, hot water, circulation, extract and supply air.

Example: In order to determine whether a pipe is a cold or hot water pipe requiring different dimensioning criteria, the system class is used.

Service types

Service types are used to classify cable trays, cable ladders and conduits. Examples are general supply, information and communication technology, security supply.

Application

To specify to which pipes, ducts and components the disciplines and system classes/service types belong, select the discipline and the desired system class or service type before using the design commands.

Background information

The Revit concept of the system types is used in the background. A system type is created for each combination of discipline and system class. Example: A system type with the name C_Supply is generated from the cooling discipline and the sypply system class for the supply of a cooling system. This is then assigned to the pipes created during construction. The components take this information from the pipes and ducts and are therefore also assigned to disciplines and system classes.
