Dewey Modelit and Howe: BIM for Existing Structures
Collapse Expand


Capitalizing on Building Information Modeling (BIM) for new buildings is easy—you get to start with a fresh, clean file, and you can lay out everything you need precisely where it’s supposed to be. But what if you’re doing an addition, a renovation, or a historic preservation? Maybe you have existing drawings. (Maybe they’re accurate!) Maybe you have some reality capture data. But most of what is important to a structural engineer is probably hidden behind an existing facade or finish. And yet the model must go on. Join this session to see how one firm has dealt with the challenges of managing uncertainty and balancing precision with usability in models of existing buildings.
