The Information Delivery Manual (IDM) for the Design to Construction Data Exchange for Highway Bridges, 1st Edition, is a reference for a standardized set of information to serve one specific use case: the exchange of model-based information to execute the construction. Its goal is to support the development of a range of technical solutions for computer interoperable information exchange for highway bridges and related structures in the United States. It is designed for use by software vendors and state departments of transportation to map the information exchange requirement to version 4.3 of the Industry Foundation Classes schema.
