This enumeration identifies different types of distribution systems. It is used to designate systems by their function as well as ports of devices within such systems to restrict connectivity to compatible connections.
HISTORY New enumeration in IFC4.
Ports for cable carriers may be connected using IfcCableCarrierSegment and IfcCableCarrierFitting. Type objects for cable carrier segments and fittings (IfcCableCarrierSegmentType and IfcCableCarrierFittingType that are not specific to a particular system type may have ports with PredefinedType of NOTDEFINED which indicates that occurrences of such objects may connect to ports of any other cable-carrier based port. Valid enumerations for cable carriers are the same as that for cables, and may be asserted if ports of the contained cables are all of the same type.
Arbitrary chemical further qualified by property set, such as for medical or industrial use.
Compressed air system.
A transport or network dedicated to control system usage.
Arbitrary supply of substances.
Arbitrary disposal of substances.
Unheated potable water distribution system.
Heated potable water distribution system.
A path for equipotential bonding, conducting current to the ground.
A circuit for delivering electrical power.
Exhaust air collection system for removing stale or noxious air from one or more spaces.
Fire protection sprinkler system.
Arbitrary supply of fuel.
Water or steam heated from a boiler and circulated through radiators.
A circuit dedicated for lighting, such as a fixture having sockets for lamps.
Items consumed and discarded, commonly known as trash or garbage.
Oil distribution system.
A path for power generation.
Rainwater resulting from precipitation which directly falls on a parcel.
Refrigerant distribution system for purposes of fulfilling all or parts of a refrigeration cycle.
A transport or network dedicated to security system usage.
Sewage collection system.
A raw analog signal, such as modulated data or measurements from sensors.
Stormwater resulting from precipitation which runs off or travels over the ground surface.
A transport or network dedicated to telephone system usage.
A transport of multiple media sources such as analog cable TV, satellite TV, or over-the-air TV.
Vacuum distribution system.
Ventilation air distribution system involved in either the exchange of air to the outside as well as circulation of air within a building.
Water adversely affected in quality by anthropogenic influence, possibly originating from sewage, drainage, or other source.
Arbitrary water supply.
A longitudinal distribution system that supports contact wires, including catenary wire droppers and stich wires.
An overhead contact line system above the upper limit of the train using an overhead contact line and a catenary system to supply current to traction units.
A distribution system which forms the intended path for the traction return current and the current under fault conditions.
Represents all wired networks that provide a data transmission channel using optical fiber cables, copper cables or both. It aggregates many technologies that are based on the multiplexing method.
A system that allows communications between operators (e.g. switchtender, traffic regulator, operational agents, etc.) in operational centers and on the infrastructure site (e.g. railway, tunnel or road).
Mobile network insures wireless communication by providing a secure platform for voice and data communication between infrastructure operators, including drivers, dispatchers, shunting team members and station controllers.
