We recently completed a Revit Model of Boston City Hall for Utile. The Revit model was built from historical construction documents in PDF and CAD formats. The model scope included the exterior with some site context, as well as the interior core areas. The project was delivered over a period of 8 weeks. We think the model turned out great!
We tested various modelling approaches for the exterior, and reviewed and discussed the pros and cons of each approach before deciding upon using curtain walls.
With multiple floor level changes and exposed structure, the interiors are just as complex as the exterior.
