The typical structural plan is divided into the following sections: General Notes, Plans, Elevations, Sections, and Details. General Notes are included with structural drawings and cover the codes used in the design and the building's bylaws. Typically, these drawings do not have any details. Structural notes describe general material properties (such as steel or wood grade, concrete strength, and so on) or construction requirements (soil compaction, weld procedures, etc.). The structural notes also include design criteria information (gravity, seismic, and wind loading). The typical structural plan drawings depict the building's foundation, floor plan, and roof plan. These plans include details such as the size and location of the structural elements defined.
