This course on shop drawings in the FHWA Steel Bridges Handbook covers the importance of detailed and accurate shop drawings for steel bridge construction. Shop drawings are used to communicate the design intent to the fabricator, erector, and contractor, and include a range of drawings such as general arrangement drawings, camber diagrams, cross-frame and diaphragm details, and field bolt lists.

The course explains the purpose and content of each type of drawing, as well as the specific details and requirements that need to be included for the proper construction and assembly of the bridge. Also discussed are the unique challenges that arise with skewed bearing lines and staged construction and guides on how to address these challenges in the shop drawings. Finally, the course stresses the importance of collaboration between the detailer, fabricator, erector, and engineer to ensure a successful project outcome.
