The former describes the dimensioned plans and explains the geographic location of each of the steel components within the whole structure in an exact and detailed manner. It includes specific information about the installation requirements, each component’s position, and all other important considerations such as wedge anchors, bolt installation and welding spots.
The latter shows every little detail of each piece of the steel structure, for instance joints, beams, braces, and columns. It also details the manner in which each of these components should be made by a steel fabricator.
Shop drawings entail material specifications, component sizes and dimensions, surface specifications, bolting, welding, painting details, and other details that pertain to each component’s fabrication. This drawing is only necessary for fabrication purposes. It doesn’t contain any details about the setting up or installation of these steel components.
The steel structure’s design, soundness, as well as strength are the exclusive responsibility of the structural engineer. These should be looked at while complying with the major building and dimension codes that were set by the architect. On the other hand, it is the responsibility of the detailer to get the steel detailing drawings approved by the structural engineer and architect before releasing it for fabrication.
