Hey all – we are a team that is in the process of adding IFC4.3 support for our bridge modeling/analysis program, a large portion of which deals with soil-structure interaction. As a result, our program offers users the ability to specify a wide range of soil properties. However, the property set Pset_SolidStratumCapacity, which is associated with the element type IFCSolidStratum, does not support many of the soil parameters that users are able to specify for a soil layer within our program. Some of these parameters are the subgrade modulus, mass modulus, and unconfined compressive strength of the soil layer.
We wanted to know if anyone has been successful in adding such properties to an IFC model. Is there perhaps another property set that we should be using? We checked all seven property sets associated with IFCSolidStratum and none of them contain the parameters that we need to add.
If there truly is no built-in support for these parameters, is there some kind of work around short of requesting that these properties be added to the schema? For instance, would we be able to create a custom property set?
