In the structural fabrication and construction industries, the duties of a rebar detailer are to create structural drawings or project plans using AutoCAD or another computer-aided design program to describe the specifications for rebar or other steel construction materials in a project. As a rebar detailer, you develop shop drawings, which indicate what types of rebar or structural reinforcements are necessary for a project, whether it is a building construction project or sets of prefabricated components. The drawings include detailed images and explanations of how the builders plan to use rebar. In addition to design rendering responsibilities, your reports include technical specifications for the various types of rebar needed.
