SC stands for which term?

• A. Site Coordinator
• B. Subcontractor
• C. System Controller
• D. Safety Compliance

Answer: (B)

In project documentation, SC is a shorthand used to identify the party responsible for a particular scope of work. The Subcontractor is the firm hired by the general contractor to perform specific trades or specialties, such as electrical, plumbing, or mechanical systems. When you see SC on schedules, drawings, or commissioning plans, it designates the Subcontractor who owns and is responsible for that portion of the work, including providing access, coordinating with the commissioning team, and ensuring readiness for testing.

The other options don’t fit as consistently in this context. Site Coordinator is a role that can exist on a site but isn’t the standard meaning of SC in typical construction and commissioning documentation. System Controller usually refers to a device or role that operates a control system, not the party responsible for a scope of work. Safety Compliance denotes a function or requirement, not a contractor entity.
