Demolition Work

Site Safety during Demolitions-Part E

If you have to do some demolition work before you build, Part E is the section of the National Building Regulations that you need to familiarise yourself with. But really all it states is common sense and caution. There are only three elements that are covered: 1 – demolition itself, 2 – making sure basements are safe during and after demolitions, and 3 – prohibition of dangerous methods of demolition. And if you contravene any of these, or ignore any notices, conditions, or orders that relate to the demolitions, you will be considered to be guilty of an offense.

Demolition of a Building

First and foremost you have to get permission from your local authority before you can demolish a building or solid structure on your property.

Very often the local authority will give permission, but at the same time impose specific conditions that must be adhered to according to Part F of the National Building Regulations – Site Operations.

Essentially the sub-regulations they normally refer to are those that relate to the safety, health, and convenience of the public, and those that aim to prevent damage to property, which might include neighboring buildings, not just the structure that you are wanting to pull down.

The building regulations state categorically that nobody is allowed to leave any building that is in the process of being demolished, or which has been demolished, in a dangerous condition. Again this is primarily to protect members of the public as well as neighboring properties.

If the local authority finds that the site is dangerous in any way, they can serve a notice requiring you to immediately make it safe, and if you don’t, they can do the necessary work and then hold you liable for costs.

Safeguarding Basements

Basements can cause great challenges during and after demolition, particularly when a building is flattened to ground level. In this event the owner of the property must ensure that there is safe lateral support for the sides of the basement.

Prohibition of Dangerous Methods

Safety is paramount, and the local authority will decide whether or not you may use a particular method of razing. For instance, blasting in a built-up suburb may be considered a danger to either other buildings or people, or both. If they do not allow a particular method to be used, the owner of the property is entitled to a relevant reason, in writing.

The Dangers Of Any Demolition Work

Building demolitions can be a dangerous activity that is often underestimated or overlooked. Demolitions involve a range of hazardous activities such as the use of explosives, heavy machinery, and other hazardous materials that can place workers and the public at risk. Building demolitions can cause serious injuries, death, and damage to property if not executed correctly.

The use of explosives is one of the most common and dangerous aspects of demolition work. If used incorrectly, explosives can cause serious injury or death due to the force of the blast and the risk of flying debris. It is essential to properly plan and execute clearance activities involving explosives to ensure the safety of workers and the public.

Another significant risk during building demolitions is the use of heavy machinery. This includes the use of cranes, bulldozers, and other specialized equipment for the levelling process. These machines can cause serious injury or death if handled incorrectly or if the operator is not properly trained. Additionally, certain machines used during demolitions can create hazardous dust or fumes, which can be dangerous to workers and the public if not managed properly.

Aside from these risks, demolitions can also cause environmental damage. The release of hazardous materials such as lead, asbestos, and other contaminants from the flattening process can be harmful to the environment and human health. It is important to take proper safety precautions and dispose of hazardous materials properly to avoid environmental damage.

In addition, pulling down of any structure can cause safety concerns for nearby buildings and structures. Flying debris from the tearing down process can cause damage to neighboring structures, and the vibrations from the leveling

can cause damage to underground utilities. It is essential to take proper safety precautions and plan the tearing down process to minimize the risk of damage to nearby buildings or structures.

Overall, the dangers of building leveling should not be underestimated. It is essential to take proper safety precautions and plan the demolition process to minimize the risk of injury, death, property damage, and environmental damage. Proper training of workers involved in demolitions and proper disposal of hazardous materials should also be taken into consideration to ensure the safety of workers and the public.
