What is a shop drawing?

A shop drawing is a detailed drawing or set of drawings that are produced by the manufacturer, contractor, or subcontractor for construction purposes. It shows the construction and installation requirements of the products and materials specified in the project design and provides additional details that are not included in the design drawings. Shop drawings typically include dimensions, materials and finishes, fabrication and installation instructions, and other important information necessary for the construction process. They are an essential element of the construction process as they help to ensure that the design specifications are accurately realized.
