Which acronym stands for Subcontractor?

• A. SC
• B. QC
• C. QA
• D. RFI

Answer: (A)

Understanding common acronyms for project roles helps you read docs quickly. SC stands for Subcontractor, the party hired by the main contractor to perform a portion of the work. In many project and commissioning contexts, you’ll see a list of participants or trades labeled with abbreviations, and Subcontractor is typically abbreviated as SC.

The other terms refer to different concepts: Quality Control (QC) is the procedures that check whether work meets requirements, Quality Assurance (QA) covers the overall process to prevent defects, and a Request For Information (RFI) is a formal inquiry to clarify design or contract details. These are not people or roles, which is why they don’t fit if you’re asked to identify who the Subcontractor is.
