Description

Use of IfcBuiltSystem/TUNNEL_PRESUPPORT, is good

But a pipe umbrella consists of an "assembly" of pipes, the individual pipes are modelled, the properties of the pipe umbrella apply more to the combined pipes
Propose we add:
IfcElementAssembly/TUNNEL_PRESUPPORT
For the pipe umbrella, properties such as spacing, length, overlap, offset, basic geometry etc apply to the assembly, pipe properties to the individual pipes

Example pre-support
