Type definition

This container defines the different predefined types of earthworks fill elements that can specify an IfcEarthworksFill.

Enumeration definition

Constant	Description
BACKFILL	Fill behind retaining walls or other structures such as quays, behind abutments and bridges.
COUNTERWEIGHT	Embankment built on the side of the main road structure to reduce the settlement of the road.
SUBGRADE	Type of earthworks element forming the structure below pavement and above natural soil. NOTE Definition from ISO 6707-1: upper part of the soil, natural or constructed, that supports the loads transmitted by the overlying structure of a road, runway, or similar hard surface. NOTE Definition from PIARC: Upper layer of the natural ground upon which the pavement is constructed.
EMBANKMENT	Predominantly longitudinal type of earthworks element with no other particular assigned type according to its role in Pavement or Subgrade. NOTE Definition from ISO6707-1: section of earthworks, often formed by cut or fill, where the finished ground level is above or below original ground level and whose length usually greatly exceeds its width.
TRANSITIONSECTION	Section of subgrade to ensure the consistency of stiffness and prevent uneven settlement. Transition section may appear e.g. between: embankment and bridge abutment; embankment and transverse structure; cutting and tunnel; embankment and cutting.
SUBGRADEBED	Upper part of the soil, natural or constructed, that supports the loads transmitted by the overlying structure of a road, runway, or similar hard surface.
SLOPEFILL	Side slope (batter) fill abutting the road structure or back slope fill.
USERDEFINED	User-defined type
NOTDEFINED	Undefined type.
