A worksheet provides the designer a representation of a measure that allows for input of specific design criteria. The plan designer will be required to assess field conditions and apply engineering principles to determine dimensions and specifications. An exhibit is a representa-tive view of a measure. An exhibit often includes standardized dimensions and specifications. Several exhibits are only a representative view of the measure, and will require the designer to assess field conditions and input dimensions and specifications for the measure. These exhibits have been identified with a note.
