Guides / Roles

TWC or TWS: who does what?

Two roles come up again and again.

Temporary Works Coordinator (TWC)

The person who looks after the temporary works process for a project. They keep the register, make sure designs are briefed and checked, and issue the permits. They coordinate. They do not have to do the designing.

Temporary Works Supervisor (TWS)

The person who supervises a particular piece of temporary works being built, used and taken down, and who makes sure it is built as designed. Think of them as the person on the ground who answers for that item.

Who else is involved

• Designer (TWD): designs the temporary works.
• Design checker (TWDC): checks the design. Must be independent of the designer at the right level.
• Permanent works designer and principal designer: make sure temporary works fit with the permanent design.

Which role is held by whom is for the company to decide, and the people appointed must be competent for it. Appointment forms are in the shop.
