No Qto related to IfcUndergroundExcavation

[FLR3DS]

Shall we consider that Qto_EarthworksCutBaseQuantities applies to this entity, in addition to IfcEarthworksCut?

[larswik]

We are in the middle of the work with Pset and Qto definitions for Geotech, Systems and Excavation/Support. In IFC Tunnel, we added the abstract entity IfcExcavation with IfcEarthworksCut and IfcUndergroundExcavation as subtypes. The quantities in Pset_EarthworksCutBaseQuantities are certainly applicable for all types of excavations which means that we basically need a new Qto_ExcavationBaseQuantities (deprecating Qto_EarthworksCutBaseQuantities). Alternative would be adding a Qto_UndergroundExcavationBase with essentially the same quantities.

[FLR3DS]

What do you mean exactly by the flag 'wontfix'? The standard will never propose a Qto for IfcUndergroundExcavation?

[larswik]

I think that this flag is a bit misleading. Of course there will be a Qto.

[pjanck]

The flag only means, that currently we won't fix it. It remains open and on our ToDo list - we will remove the flag as we will tackle it.

[pjanck]

Renamed to backlog to better convey our intentions.

[FLR3DS]

Since you 'are in the middle of the work', shall I wait to raise similar issues on other entities or shall I raise one issue per entity right now?

[larswik]

I would prefer that you register issues for the backlog so nothing is forgotten. Thank you in advance for any contributions!
