What is the Difference Between Temporary Works Supervisor and Coordinator?

In the construction industry, temporary works are a critical part of ensuring projects are completed safely and efficiently. To manage these effectively, the CITB has established clear roles for Temporary Works Supervisors (TWS) and Temporary Works Coordinators (TWC).

Both roles are essential, but they carry different responsibilities. Understanding these differences is key to ensuring the right people are trained and competent.

Temporary Works Coordinator (TWC)

The Temporary Works Coordinator is the central figure responsible for the overall management of temporary works on site. They are appointed by the designated individual in the company and have a duty to ensure that all procedures, checks, and approvals are carried out correctly.

Key Responsibilities:

• Coordinating all aspects of temporary works design, checking, and implementation
• Ensuring risk assessments, method statements, and permits are in place
• Communicating with designers, contractors, and supervisors to ensure compliance
• Making sure temporary works are removed safely when no longer required

The TWC course is designed for those who have overall responsibility for managing temporary works, usually site or project managers.

Temporary Works Supervisor (TWS)

The Temporary Works Supervisor works under the direction of the Coordinator but plays a vital role in monitoring and supervising temporary works on site. While they don’t carry the same level of overall responsibility as a Coordinator, they ensure that daily operations comply with the agreed designs and procedures.

Key Responsibilities:

• Supervising the implementation of temporary works as per the design and procedures
• Checking that control measures are followed correctly on site
• Reporting to the Coordinator any issues, risks, or deviations from the plan
• Assisting in maintaining safety standards and compliance with legislation

The TWS course is aimed at supervisors, foremen, and those directly overseeing site activities.

Temporary Works Supervisor vs Temporary Works Coordinator

While both roles are crucial, the difference lies in their level of responsibility:

• The Coordinator (TWC) has the overall responsibility for managing temporary works procedures and ensuring compliance.
• The Supervisor (TWS) ensures that those procedures are carried out correctly on site on a day-to-day basis.

In short, the Coordinator plans, organises, and manages, while the Supervisor ensures safe and correct execution.

Why Training Matters

Both roles are CITB-accredited courses, forming part of the Site Safety Plus scheme. They help organisations meet the legal requirement to appoint competent persons in charge of temporary works.

By training staff in either or both courses, companies can:

• Reduce the risk of accidents and costly mistakes
• Ensure compliance with UK legislation
• Improve communication between supervisors, coordinators, and contractors
• Build safer and more efficient working environments
