Temporary works
The Temporary Works Supervisor (TWSTC) and Temporary Works Co-ordinator (TWCTC) training courses equip site professionals with the skills to manage and supervise temporary works safely, focusing on co-ordination, communication and regulatory best practice.
CITB has developed three temporary works training courses for the construction industry. These include:
TWSTC is designed to help those on site with responsibility for supervising temporary works in all its forms, while TWCTC and TWCTC-R are focused on those with responsibility for managing temporary works. All three courses aims to improve knowledge of processes, the need for and duties of a temporary works supervisor or co-ordinator, the roles of others, and of the relevant British Standard, BS 5975.
Temporary works document templates
These templates are designed to support the exercises from the training courses and represent what is typically required from such documents:
It can be helpful to see forms used ‘in action’ to understand the level and type of information that is expected. These forms are completed examples based on the blank templates above. They are based on a scenario that is outlined in the first document in this list.
Simplified temporary works flowchart
A simplified temporary works flowchart has been developed with the support of Andun Engineering Consultants, the flowchart breaks the project steps down into:
