What is the purpose of submittals and shop drawings in CD phase?

• A. Submittals confirm products meet specs; shop drawings provide manufacturer details for fabrication and installation
• B. Submittals replace the need for shop drawings
• C. Submittals are optional and do not affect the construction
• D. Shop drawings describe site logistics only

Answer: (B)

Submittals and shop drawings in the Construction Documents phase establish alignment between design intent and actual built work. Submittals verify that proposed products and materials meet the contract specs and provide the information the design team needs to approve them before they are used. Shop drawings, produced by contractors or fabricators, translate the design into exact fabrication and installation details—showing precise dimensions, connections, tolerances, mounting methods, and installation sequencing.

Together, they let the architect/engineer review for conformity and coordinate interfaces before construction begins, helping prevent clashes and costly changes later on. These documents are required by the contract and are not interchangeable or optional. Submittals aren’t about site logistics; they focus on products and methods, while shop drawings provide the detailed fabrication and installation guidance that the field uses.
