What specific 3D model formats need to be supported?
The topic description mentions that the solution should be “agnostic to any specific authoring tool or 3D model format”. How central is IFC to this topic and should our solution be able to view file formats other than IFC?

IFC is critical as the American Association of State Highway and Transportation Officials (AASHTO) has adopted the IFC Schema as the national standard for AASHTO States and is a "Principle Member" of BuildingSMART. It may take further deployment efforts before a majority of designs are exported in IFC, yet model as the legal document (MALD) projects are already being deployed. See links below.
