Controlled demolition is a type of demolition work that is carried out in a controlled and safe manner.
Demolition work refers to the process of tearing down buildings or other structures. There are different types of demolition work, each with its own specific purpose. All demolition work should be carried out by professional contractors who have the necessary experience and expertise to conduct safe and efficient demolition.
If you are considering demolition work, always get in touch with a professional such as DES Holdings.
What is Controlled Demolition?
The first step in any demolition project is to create a demolition plan. This plan will detail the steps that need to be taken in order to safely and effectively carry out the demolition work. The type of demolition work that is required will dictate the specific steps that need to be included in the demolition.
There are different types of demolition, such as:
Total demolition
Controlled demolition
Selective demolition
Interior demolition
This blog will discuss controlled demolition, which is explained below.
Controlled Demolition
Controlled demolition is a type of demolition work that is carried out in a controlled and safe manner. Generally speaking, a controlled demolition can involve the use of explosives and bulldozers, and other specialist equipment. However, owing to the importance of safety and the spread of dust and debris, explosives are not often used.
The process of using explosives is called ‘implosion’ and ensures the strategic collapse of a structure or building by placing explosives in a pre-determined sequence for a controlled collapse.
Controlled demolition that does not use explosives is typically used for larger buildings or structures where precautions should be taken to ensure the utmost safety of everyone involved in the demolition process.
Why Is Controlled Demolition Used?
For tall buildings and structures such as bridges, a controlled demolition will ensure the most effective demolition method, while also ensuring minimum disruption to the general public.
Controlled demolition is also used when a building or structure contains hazardous materials such as asbestos. The use of explosives in a controlled demolition will ensure that any asbestos is properly contained and does not pose a risk to the public.
Controlled Demolition Requirements
In order to carry out a controlled demolition, the contractor will need to obtain a permit from the local authorities. The contractor will also need to create a detailed demolition plan, which outlines the specific steps that need to be taken in order to safely carry out the demolition work. You can read about the planning requirements for demolition here.
Once the demolition plan has been approved, the contractor will begin preparations for the controlled demolition. This may involve setting up scaffolding or other support structures around the perimeter of the building. The contractor will also need to secure any loose debris that could potentially fall from the building during the demolition process.
Once all preparations have been made, the contractor will begin the controlled demolition by carefully breaking down the structure of the building. This is typically done using heavy machineries such as excavators or cranes. The contractor will need to take care to avoid damaging any nearby buildings or structures. Once the demolition is complete, it is the job of the contractor to clear away any debris and ensure that the area is safe for everyone to use.
The contractor will also need to submit a final report to the local authorities detailing the demolition work that has been carried out. This report will include information such as the type of demolition, the date of the demolition, and the contact details of the contractor.
Controlled Demolition Techniques
Diamond drilling – this is a type of drilling that uses a diamond-tipped drill bit to create holes in concrete and other hard materials to create flawless holes measured to precision. The diamond drill is a strong, resilient material that can effectively cut through glass, metal, and concrete.
Hydraulic bursting and crunching – this method involves using high-pressure water jets to break down concrete and other hard materials in a safe way. The hydraulic bursting heads will be placed in the drilled holes. This creates a splitting force of a maximum of 500 tonnes to crack the material. Once the material has been cracked, the ‘crunch’ will begin to demolish the material further.
Brokk robot demolition – the Brokk robot is a remote-controlled demolition machine that can enter small spaces and carry out demolition work in a safe and controlled manner via the use of a remote. The machine is fitted with a hydraulic breaker attachment, which can break down concrete, brickwork, and metal. The machine is precise and can complete the job quickly, while also being able to fit into hard-to-reach spaces and even climb stairs. The Brokk robot is incredibly useful for demolition work, as it negates human error and does not require a person to do the dangerous work themselves.
What Are the Benefits of Controlled Demolition?
It is a safe and effective way to demolish a building or structure.
It minimises the risk of damage to nearby buildings or structures.
It reduces the amount of dust and debris that is produced during the demolition process.
It ensures that any hazardous materials are properly contained and disposed of.
What Are the Disadvantages of Controlled Demolition?
It can be a more expensive option than traditional demolition methods.
It requires a permit from the local authorities.
It can be a more time-consuming process than traditional demolition methods.
Demolition work is incredibly dangerous and should be carried out in accordance with the necessary guidelines. If you would like to know more about our demolition services or the other services we provide, please get in touch with us directly.
