The cost of making shop or working drawings for steel structures is usually figured by the:

• A. Number of sheets required for layout, details, erection diagrams, etc.
• B. Total weight of steel
• C. Project duration
• D. Labor hours

Answer: (A)

Shop drawings are the drafting work needed to turn design intent into precise fabrication and erection information. The amount of drawing effort scales with how much documentation must be produced, and that is best represented by the number of sheets required for layouts, details, and erection diagrams. Each sheet involves time to create views, dimensions, callouts, notes, and revisions, so more sheets mean more drafting hours and coordination. That’s why pricing is typically done on a per-sheet basis. Basing cost on the total weight of steel would reflect fabrication, not drawing effort, and project duration doesn’t directly measure the amount of drawing work. Occasionally drafting may be billed by hours, but standard practice is to price by sheet, with complexity potentially increasing the effort per sheet.
