Difference Between Temporary Works Coordinator and Supervisor

11 September 2025

2 min read

Temporary works are essential on construction projects: scaffolding, formwork, excavation supports and other structures that enable permanent works. Managing these operations safely and efficiently requires skilled oversight. Two key roles ensure this happens: the Temporary Works Coordinator (TWC) and the Temporary Works Supervisor (TWS).

Key Responsibilities

RoleMain Duties
Temporary Works CoordinatorHas overall responsibility for planning, design checks and approvals, risk assessments and compliance with BS 5975. The coordinator liaises with designers, contractors and clients and is accountable for ensuring procedures are followed from start to finish.
Temporary Works SupervisorWorks on site to make sure the approved designs and procedures are implemented correctly. The supervisor monitors daily activities, identifies hazards, and reports back to the coordinator.

Training Focus

CourseWhat You Will Learn

Temporary Works Supervisor Online CourseFocuses on practical site supervision, daily checks, communication with the coordinator and ensuring all work follows the agreed design and safety plan.

Deciding Which Course Fits Your Role

  • Choose the Coordinator course if you will approve designs, manage risk assessments, and coordinate all parties involved.
  • Choose the Supervisor course if your primary role is day-to-day site supervision, ensuring all temporary works are built and maintained safely.
  • Consider both courses if you expect to cover both responsibilities on smaller projects or want to broaden your competence.

Why the Difference Matters

Clear separation of duties ensures legal compliance, better safety management and smoother project delivery. Coordinators focus on the big picture and formal approvals, while supervisors make sure plans are followed on site every day. Both roles are essential for meeting BS 5975 and CDM regulations.
