In the design phase a "reinforcement instruction" may be constructed as in the attached images. (See also attached doc). image image This is very similar to what is described in the issue about mapped zones (https://github.com/bSI-InfraRoom/IFC-Specification/issues/358). What is described here is a "screen" with longitudinal and lateral (roof/wall) extensions with a couple of design parameters:

Compare this with the modelling of individual bolts in an as-built model.

Do we cover this in the current IFC Tunnel proposal or do we e.g. need an Entity for this "screen" to which the design properties may be assigned?

358 : Similar way of describing/mapping zonal features

484 : Design vs as-built information for injection

485 : general issue about design vs as-built properties

In the discussion with the Excavation team, it was decided that IfcTunnelSection/SUPPORTSECTION could be used for this (see #482)
