W hat you need to know about demolishing a building.

Demolition of a building is a process that requirescareful planning, specialized personnel and compliance with legislation. It is considered necessary when a buildinghas been deemed dangerous, is unsuitable for use, space is required for new construction or when part of the building must be removed for renovation.

However, demolition is not a simple matter. It involves multiple challengessuch as:

  • The choice of the appropriate method (mechanical demolition, demolition with explosives, gradual dismantling). 
  • The management of the waste produced. 
  • Compliance with environmental regulations. 
  • Ensuring the safety of personnel and the surrounding area. 

One ​​of the most critical factors influencing the decision to demolish is the cost. Let's see what it depends on and how it is formed.

Factors affecting the cost of building demolition

The cost of demolishing a building is not fixed. Many factors affect the total cost, and a correct estimate is crucial for the project budget.

Size and type of building.

The larger and heavier the building, the higher the cost. A small single-family home has different requirements than a multi-story building or an industrial building.

Demolition method.

Mechanical demolition with excavators and hydraulic shears is the most common and economical method. On the other hand, the use of explosivesincreases the cost due to the expertise required and the additional safety measures.

Access and area.

If the building is located in an urban environment, the process becomes more complicated due to neighboring buildings, traffic regulations, and stricter regulations. Conversely, in remote areas the cost may be lower.

Construction materials.

The type of materials determines whether demolition will be quick or demanding. For example, a building made of reinforced concreterequires heavy machinery and more time than a wooden or metal one.

Waste management and disposal.

The removal and management of demolition products significantly affects costs. In many cases, special licensing is required to transport the debris to licensed disposal or recycling sites.

Special conditions and additional costs

If the building contains hazardous materials (e.g. asbestos), special demolition and safe disposal measures are required, increasing costs.

Demolition permits. What you need to know?

In order for the demolition of a building to proceed, a demolition permitis usually required, which is issued by the competent urban planning authorities.

When is a demolition permit necessary?

  • For most buildings, whether residential or commercial.
  • When demolition may affect neighboring structures.
  • If the area is designated as conserved or protected.

Are there cases where a permit is not required?

There are some exceptions, such as small demolitions within private plots, which do not affect the statics of the rest of the building. However, even in these cases, it is necessary to consult an engineer.

Supporting documents for issuing a demolition permit

The basic documents required include:

  • Property titles and topographic map.
  • Static study of the building.
  • Approval from the Urban Planning Department.
  • Waste management plan (according to legislation).

Waste management and recycling

The management of demolition products is mandatory and regulated by environmental regulations. Rubble cannot simply be dumped in uncontrolled areas.

What materials can be recycled?

  • Concrete and bricks, reused in construction work.
  • Metals, which are sent for melting and recasting.
  • Wooden materials, which can be processed or used as fuel.

How is waste disposed of?

The work must comply with the prescribed procedures. Exorixi undertakes the complete management of waste, from collection and transportto disposal or recycling in licensed facilities.

Demolition of a buildingis not a simple process. The cost depends on many factors, such as the size of the building, construction materials, area and management of the debris. In addition, proper legal compliance and environmental responsibilityare essential for a safe and efficient execution of the project.
