What You Need to Know About Temporary Works in Demolition Projects

Temporary works can include but are not limited to: scaffolding – used to create a temporary structure that is used to provide access to work at height; or hoardings – which are temporary barriers or fencing used to enclose a demolition site and to protect the public.

On more complex structures, and particularly where façade retention or shoring of basement walls is required, other systems such as RMD may be the most appropriate solution.

All temporary works are designed to be removed once the project is complete however it is important consider their design, location and the space they take up during the course of the project. Engaging the demolition contractor as early as possible, even during the design stage of a project can reap benefits. Installation of the wrong solution or system can alter the demolition and subsequent construction methodologies, which can result in both increases in cost and programme.

In this blog, we look at the key things you need to know about Temporary Works used in demolition projects:

1. Legal Requirements: Depending on your location, there may be legal requirements and regulations regarding temporary works. Ensure that you comply with all relevant legislation, obtain the necessary permits, and follow local guidelines to avoid any legal issues. The regulations that apply to temporary works will vary depending on the type of demolition or remediation to be carried out and the site conditions.

2. Temporary Works Design: Temporary works can be complex and require specialist knowledge to design and install and it is therefore important to work with competent professionals. They will assess the specific requirements of your demolition project and design appropriate temporary structures, such as scaffolding, propping, shoring, or falsework to ensure that the temporary works are safe and fit for purpose.

When designing and constructing temporary works, it is important to consider the following factors:

• The type of demolition project: this will determine the type of temporary works that are needed. For example, demolition of a high-rise building will require different temporary works than a low-rise building.

• The site conditions: such as the ground conditions and the weather, will also affect the type of temporary works that are needed.

3. Risk Assessment: You will need to conduct a thorough risk assessment to identify potential hazards and risks associated with the demolition project. Temporary works should be designed to mitigate these risks and ensure the safety of workers, the public, nearby structures, and the environment. Working with a professional contractor will ensure you help conduct a detailed and methodical risk assessment.

4. Monitoring and Inspections: Temporary works must be regularly inspected to ensure that they remain safe and fit for purpose. This includes visual inspections, as well as more detailed inspections by a competent person. Any defects or issues must be addressed promptly to ensure the safety of workers and the public. Establish a schedule for inspections and maintenance, and document all findings and actions taken.

5. Communication and Collaboration: Effective communication and collaboration between all parties involved in the demolition project are essential. This includes contractors, engineers, designers, and temporary works coordinators. Clear communication channels will help address any issues promptly and ensure everyone is aware of their responsibilities.

6. Documentation: Keep detailed records of all temporary works design, inspections, maintenance, and any modifications made during the project. This documentation will be valuable for future reference, audits, and potential legal requirements.

7. Training and Competence: Ensure that all personnel involved in the demolition project, including workers and supervisors, are adequately trained and competent in working with temporary works. This will help prevent accidents and ensure the project’s smooth execution.

8. Review and Adaptation: Regularly review the effectiveness of your temporary works and adapt them as necessary. As the demolition project progresses, the requirements may change, and adjustments may be needed to maintain safety and efficiency.

In conclusion, temporary works are an essential part of almost any construction project. They are a legal requirement and must be properly designed, installed, and maintained to ensure the safety of workers and the public. By working with a specialist temporary works designer and keeping detailed records, you can ensure that your temporary works are safe, fit for purpose, and compliant with all relevant regulations.
