When it comes to managing temporary works on a construction site, clear roles and responsibilities are essential. Whether you're supervising excavation support or coordinating scaffold design checks, proper training ensures that everyone involved understands their legal duties and risk management procedures.
In this blog, we break down the difference between Temporary Works Supervisors (TWS) and Temporary Works Coordinators (TWC) — and guide you to the right training for each role.
What Are Temporary Works?
Temporary works are structures or systems needed to support the permanent works during construction, such as:
- Scaffold towers
- Formwork and falsework
- Excavation supports
- Temporary access roads or bridges
Because failures in temporary works can lead to serious injuries, delays, and legal consequences, the CITB recommends formal training for those managing or coordinating these operations.
The Two Key Roles: Supervisor vs Coordinator
Temporary Works Supervisor (TWS)
The Temporary Works Supervisor is responsible for:
- Ensuring temporary works are implemented on-site safely and correctly
- Checking that all risk controls and design instructions are followed
- Liaising with the Temporary Works Coordinator
This role is usually suited for site supervisors, foremen, or experienced operatives involved directly with implementation.

Temporary Works Coordinator (TWC)
The Temporary Works Coordinator has a more strategic and administrative role:
- Approving temporary works designs before they are implemented
- Coordinating between designers, contractors, and site staff
- Ensuring all procedures align with BS 5975 and company policy
This role is typically held by site managers, engineers, or anyone overseeing temporary works across multiple projects or subcontractors.
