Structural Drawing — Shop drawings include detailed drawings of members and connections that show exactly how parts are to be fabricated and assembled; they complement, not replace, design drawings.

Introduction / Context:
Shop drawings translate design intent into buildable instructions for the fabricator. They specify sizes, lengths, hole locations, weld symbols, piece marks, and material grades, ensuring parts are produced to fit in the field.

Given Data / Assumptions:

• Design drawings indicate member sizes and overall intent.
• Shop drawings provide fabrication-level details.
• Erection drawings coordinate field assembly.

Concept / Approach:
By documenting “how to make it,” shop drawings bridge the gap between design and production. They include dimensions, tolerances, and processes (cut, drill, weld). They do not redo design calculations but must reflect design requirements accurately.

Step-by-Step Solution:
1) Start from design drawings and connection notes.2) Prepare member details with exact dimensions and hole patterns.3) Add weld symbols, piece marks, and material specs.4) Coordinate with erection drawings for sequencing and fit-up.

Verification / Alternative check:
QC checks confirm every fabricated piece can be identified, sized, and connected exactly as shown.

Why Other Options Are Wrong:
Listing only bolt counts omits critical geometry; replacing design calculations misunderstands responsibilities; showing appearance without dimensions defeats the purpose.

Common Pitfalls:
Omitting tolerances, inconsistent piece marks, or missing weld/process details.

Final Answer:
Correct
