This means the GA drawing is derived from the 3D CAD model. 3D CAD Modelling is now the standard for steel detailing. It is common practice that a General Assembly drawing is produced first for comment and approval. The steel detailer needs to convey sufficient information on the fabrication drawings to allow the fabricator to produce the required steel without any queries. The setting out of the steel (in plan and elevation) is taken from the architects’ drawings and the sizes as well as the connections from the structural engineer’s drawings. To fabricate steel one requires Fabrication Drawings.įabrication Drawings are derived from a combination of the architectural & structural engineers drawings. Steel fabricators cannot fabricate their steel from architects or structural engineers drawings. Both of these disciplines convey this information in drawings. Structural Engineers calculate, design and specify the structural elements. In basic terms, architects design the building (size, finishes, materials etc.). Steel detailing is the process of producing a set of fabrication drawings which are relied upon for the production of steelwork.
