How is the whole demolition process?

The demolition process is a complex and detailed procedure involving several stages, from preparation to final clean-up. Here is a step-by-step overview of how demolition usually proceeds:

1. Planning and preparation

The first step is detailed planning for the demolition, which includes:

• Assessing the building and structure - Evaluating the type and condition of the structure, determining what materials are used (concrete, steel, asbestos, etc.), what the risks may be (e.g., presence of hazardous materials), and what the overall demolition process will be.
• Securing permits - Obtaining all necessary permits (building permits, environmental permits, hazardous materials disposal permits, etc.).
• Establishing a schedule - Preparing a demolition schedule and budget.
• Safety precautions - Developing a safety plan for workers, the surrounding area and the public.

2. Site preparation

Several preparatory steps need to be taken before the actual demolition:

• Site clearance - All movable items (furniture, fixtures, equipment) are removed.
• Disconnection of utilities - Shut off or disconnect electricity, water, gas, sewer and other services to ensure safety during demolition.
• Marking and securing the area - The site and surrounding area shall be delineated with safety tape, fences, and signage. Delineation of danger zones for workers and the public.
• Removal of hazardous materials - If the structure contains hazardous materials such as asbestos or PCBs

3. Demolition itself

There are several methods to conduct demolition:

• Mechanical demolition - Using heavy machinery such as excavators, crushers, jackhammers and cranes to use force to dismantle the structure of the building.
• Controlled explosive (implosion) - Used in the demolition of tall buildings or chimneys. Explosives are used to destroy the structure of a building in a controlled manner so that it falls into its own foundation and does not damage the surrounding area.
• Manual demolition - Hand tools (hammers, chisels, saws) are used for more delicate work such as dismantling internal elements or in the case of small objects.

When demolishing, it is important to pay attention to:

• Controlled procedure - Demolition is carried out in a gradual and controlled manner to avoid accidental damage to the surrounding area or dangerous situations.
• Ensuring stability - When removing support structures, care is taken to ensure that other parts of the building do not fall or create a fall hazard.

4. Recycling and waste disposal

Once demolition is complete, the waste that has been generated must be taken care of. Many materials can be recycled, which helps to conserve natural resources and protect the environment. This step includes:

• Separation process - Separating recyclable materials (e.g. concrete, brick, metal, wood, glass) from non-recyclable materials.
• Waste Transportation - Recyclable materials are taken to recycling centers, while non-recyclable waste is safely disposed of according to applicable regulations.
• Ensuring the environmentally sound disposal of hazardous materials - If hazardous waste (e.g. asbestos) is present during demolition, it must be removed and disposed of according to legal regulations.

5. Cleaning and final inspection

Upon completion of demolition and waste disposal, the following is required:

• Site cleanup - Removal of all remaining materials, cleaning of the area, and preparation of the site for future use (e.g., new construction).
• Inspection - After cleanup, a final site inspection is conducted to verify that all safety standards and environmental requirements have been met. This ensures that the site is ready for the next phase (e.g., construction of a new building or other project).

6. Documentation and final report

After the demolition is completed, a final documentation is usually prepared which includes:

• A report on the progress of the demolition, including safety measures, equipment used and materials recycled.
• Documentation of the environmental disposal of the waste.
• Confirmation of compliance with all requirements (e.g. permits, safety standards, environmental standards).
