Shop Drawings.
Very often the consultant will request shop drawings for certain components during the construction
process. These are normally prepared by the contractor, subcontractor, manufacturer, or fabricator, de-

components such as windows, precast components, elevators, structural steel, trusses, or millwork. The
drawings represent the manufacturer’s or contractor’s interpretation of the consultant’s drawing and are
thus expected to show more specific detail than normally provided by the construction documents. They
are drawn to explain the fabrication and/or installation of the required product. The primary emphasis of
a shop drawing always relates to the particular product to be manufactured or its installation and ex-
cludes information regarding other products unless integration with another product is necessary.
Shop drawings should include information for the consultant to compare to the specifications and
contract documents. They should also include dimensions, manufacturing conventions, and special fab-
