What is TWSTC?

Working on temporary works can be risky business, so construction companies often bring on a special temporary works supervisor. For this role, the worker should have a TWSTC certification or equivalent training.

What is TWSTC?

TWSTC stands for the CITB Temporary Works Supervisor Training Course, which equips those who are in charge of temporary works on construction sites with the knowledge they need to carry out their duties.

This qualification allows employers to be sure that their supervisor has a comprehensive understanding of the job and can apply their expertise in real-life settings. It is not a legal requirement, but many employers will not permit supervisors to work full-time on their site without it.

The course runs for one day and can be taken online or in person. It is part of the Site Safety Plus (SSP) program from CITB, which all construction companies should ensure their relevant team members have completed.

By taking this course, participants will develop their skills in temporary works supervision, learn about their obligations under BS 5975:2019, and understand the essentials of good safety risk management and their responsibilities as a supervisor. This can help to ensure that all temporary works are completed safely and effectively.

What does a temporary works supervisor do?

A temporary works supervisor is responsible for overseeing the day-to-day operations of temporary works on site. Their primary goal is to ensure that any equipment being used is safe and suitable for the task at hand, while also promoting a safe working environment.

As part of their role, they will regularly assess the equipment and working environment, identifying any potential hazards that may cause harm to workers. This includes assessing the setup and dismantling of temporary works equipment, as the incorrect use of such equipment can lead to serious consequences.

It's the responsibility of the supervisor to take all necessary steps to guarantee the safety of workers, preventing any potential accidents or injuries that may arise. By doing so, they are able to ensure that temporary works are being used effectively and appropriately.

What is the difference between a co-ordinator and a supervisor?

They both need to work together to ensure a safe environment on site, but there are distinct roles to be fulfilled. Supervisors will report directly to co-ordinators, and they are more likely to be necessary on larger projects that span multiple sites. The supervisor will likely be in charge of one particular site or part of the project, while the co-ordinator will oversee the entire project.

In order to be qualified for these positions, many people start out as TWSs, then move on to the Temporary Works Co-ordinator Training Course (TWCTC) after completing their TWSTC. Both courses are vital for co-ordinators to have a full understanding of temporary works management.

In summary, co-ordinators and supervisors must work hand-in-hand to create a secure working environment. Supervisors may manage an individual site, while co-ordinators supervise the entire project. Training is essential for these positions, and it involves completing the TWSTC, followed by the TWCTC.

How dangerous are temporary works?

The risks of temporary works can be considerable. From falling objects to personnel plummeting from height, the consequences of poor management and maintenance of temporary works can be dire. Common causes of failure include incorrect setup, inadequate upkeep of equipment, unauthorized changes, and misuse of the structures. It is paramount that anyone working at height is appropriately equipped with safety harnesses or fall restraints to mitigate potential injury or even death.

To ensure the safety of workers, it is essential that temporary works are correctly set up and maintained. All changes must be approved and recorded by the appropriate staff member. It is also essential that the equipment is used correctly and not overloaded. Furthermore, temporary works must be dismantled and stored correctly.

It is clear that temporary works can be dangerous, and the consequences of inadequate management and maintenance can be dire. With this in mind, it is essential that correct safety protocols are followed and necessary equipment is available to protect workers. By doing so, the likelihood of serious injury or death occurring can be greatly reduced.
