5.4.2.6 IfcBuiltSystemTypeEnum
5.4.2.6.1 Semantic definition
This enumeration identifies different types of built systems.
5.4.2.6.2 Type values
| Type | Description |
|---|---|
EROSIONPREVENTION
|
A grouping of elements into a built system for preventing unwanted relocation of material particles in earthworks slopes or rock faces. Typical types of erosion prevention include: * Planting * Solid * Framework * Anchored framework * Shotcrete * Screening * Geosynthetics (geotextiles) |
FENESTRATION
|
System of doors, windows, and other fillings in openings in a built envelope that are designed to permit the passage of air or light. |
FOUNDATION
|
System of shallow and deep foundation elements that transmit forces to the supporting ground. |
LOADBEARING
|
System of built elements that transmit forces and stiffen the construction. |
MOORING
|
System of components and elements responsible for keeping or holding an element (a vessel, platform or set of catenary lines) in a desired position. |
OUTERSHELL
|
System of built elements that provide the outer skin to protect the construction (such as the facade). |
PRESTRESSING
|
System of elements providing pre-stressing to the structure, including typically manufactured products such as tendons, anchorages (active, dead, coupling), ducts, vents and deviators, and in-situ concrete segments, tendon spacers, blisters and additional reinforcements. |
RAILWAYLINE
|
A set of functional tracks with explicit terminals. It is usually composed of a set of tracks with continuous track parts and alignments. |
RAILWAYTRACK
|
Railway track system. It is usually composed of continuous sequences of track parts and alignments. |
REINFORCING
|
System of elements providing reinforcing to the structure. |
SHADING
|
System of shading elements (external or internal) that permits the limitation or control of impact of natural sun light. |
TRACKCIRCUIT
|
A track circuit is an electric circuit of which the rails of a track section form a part, with usually a source of current connected at one end and a detection device at the other end for detecting whether this track section is clear or occupied by a vehicle. In a continuous signalling system, the track circuit can be used to transmit information between the ground and the train. Note: definition from IEC 60050-82. |
TRANSPORT
|
System of all transport elements in a facility that enable the transport of people or goods. |
USERDEFINED
|
User-defined type |
NOTDEFINED
|
Undefined type. |
