CITB TWSTC Course – Temporary Works Supervisor Training
)
The CITB TWSTC Course is a one-day course designed to develop a solid understanding of the Temporary Works Supervisor (TWS) role and its place within the temporary works management process. Created in collaboration with the Temporary Works Forum, the HSE, and Build UK, this course aligns with the guidance set out in BS 5975:2019 and BS 5975-1:2024. It focuses on how effective supervision supports safe and compliant temporary works, whether on small projects or major construction sites. Rather than providing technical design training, the course emphasises the management principles and responsibilities that underpin good temporary works practice. It explores the importance of the “4Cs” – communication, co-ordination, co-operation, and competency; as key components of safe and successful project delivery.
This one-day Site Safety Plus Temporary Works Supervisor Training Course is suitable for people with experience of being responsible for temporary works.
On completion, delegates will understand the role and
responsibilities of a Temporary Works Supervisor, the relationship with the
Temporary Works Co-ordinator (TWC), and the critical part supervision plays in
maintaining control and safety standards on site.
The qualification is recognised across the UK, endorsed
by Build UK, and valid for five years
before renewal is required.
