This exchange provides a structural analysis model for a bridge design. It may be generated as part of the design and review process for original construction, or may be generated later in evaluating or maintaining existing bridges.

Information captured within this exchange includes the following:

NOTE  This exchange currently provides minimal information to be useful for the downstream Design Plans exchange; it is anticipated to be elaborated in a future extension.
