5.4.2.7.2 Type values
| Type | Description | 
|---|---|
ABUTMENT
 | 
 A bridge abutment built up of walls, beams, slabs etc.  | 
ACCESSORY_ASSEMBLY
 | 
 Assembled accessories or components.  | 
ARCH
 | 
 A curved structure.  | 
BEAM_GRID
 | 
 Interconnected beams, located in one (typically horizontal) plane.  | 
BRACED_FRAME
 | 
 A rigid frame with additional bracing members.  | 
CROSS_BRACING
 | 
 A Structural linear member or assembly of members inside a box girder or between girders, typically on a pier, to resist lateral forces and transfer them to the support.  | 
DECK
 | 
 A platform (such as floor or bridge deck) built up of beams, slabs.  | 
DILATATIONPANEL
 | 
 Device which permits longitudinal relative rail movement of two adjacent rails, while maintaining correct guidance and support.  | 
ENTRANCEWORKS
 | 
 An assembly forming the support structure of a chamber (lock, dock) gate and associated elements, plus the containment of operational equipment.  | 
GIRDER
 | 
 A beam-like superstructure, such as bridge main girder extending between abutments and piers built up of beams, braces (as Members) etc. - may also be an aggregation of girder segments.  | 
GRID
 | 
 A framework of spaced cables or bars that are parallel to or cross each other.  | 
MAST
 | 
 An assembly of plates, members, cables or fasteners that form a vertical structure for the support or mounting of other equipment such as lights, sonar or wireless transmitters.  | 
PIER
 | 
 An intermediate support e.g. in a bridge, built up of walls, columns, beams etc.  | 
PYLON
 | 
 A vertical structure supporting cables in suspended or stayed structure.  | 
RAIL_MECHANICAL_EQUIPMENT_ASSEMBLY
 | 
 A complex assembly made up of several components like blocking device, speed regulator, bias loaded inspector, track scale or controllable retarder.  | 
REINFORCEMENT_UNIT
 | 
 Assembled reinforcement elements.  | 
RIGID_FRAME
 | 
 A structure built up of beams, columns, etc. with moment-resisting joints, such as gantry  | 
SHELTER
 | 
 A structure, fairly quick to setup, move or dismantle, used to give protection, especially from the weather or intrusion.  | 
SIGNALASSEMBLY
 | 
 An assembly to physically aggregate together one or more signal instances (and also sign instances) including any supporting structural elements such as a simple pole or a rigid frame gantry.  | 
SLAB_FIELD
 | 
 Slabs, laid out in one plane.  | 
SUMPBUSTER
 | 
 An obstacle (with oil catchment basin) installed typically in a bus lane to prevent other traffic with lower ground clearance from using it. Also Sump breaker or Sump trap.  | 
SUPPORTINGASSEMBLY
 | 
 An assembly intends to support Overhead Contact Line System. It includes foundation, supporting elements and suspension assembly.  | 
SUSPENSIONASSEMBLY
 | 
 A complex assembly of components used to suspend elements or cable segments.  | 
TRACKPANEL
 | 
 Trackwork ensuring the support and guidance of a vehicle along a route. It consists of assembly of rail, sleepers and fastenings.  | 
TRACTION_SWITCHING_ASSEMBLY
 | 
 A common assembly used to insure the switching function. It is composed of switches, control instruments and other components.  | 
TRAFFIC_CALMING_DEVICE
 | 
 A structure on the carriageway to control the speed of vehicles.  | 
TRUSS
 | 
 A structure built up of members with (quasi) pinned joint.  | 
TURNOUTPANEL
 | 
 Trackwork ensuring the support and guidance of a vehicle along any given route among various diverging or intersecting tracks.  | 
USERDEFINED
 | 
 User-defined element assembly.  | 
NOTDEFINED
 | 
 Undefined element assembly.  |
