Demolition is defined as the set of operations aimed at reducing a structure or apparatus from its initial function and size to a reduced set of its component parts. The resulting materials can then be recycled and reused or given to centers and disposed of as waste.
Each building under the project has its own service life. When the period of operation comes to an end, it must be dismantled. Demolition of buildings is a kind of science, a complex technological process that requires certain experience and knowledge. The safety of people and surrounding buildings depends on the technology for dismantling buildings.
Reasons why demolition is necessary
Emergency condition of the object.
An old task whose supporting structures have lost their strength may collapse at any moment. Moreover, it can no longer be restored. That is why it is necessary to demolish the emergency building using diamond cutting as soon as possible.
Liquidation.
Liquidation is also necessary if the performance characteristics of the building have deteriorated and do not meet the standards.
Liberation of territory.
Often it is necessary to demolish old buildings in order to make room for construction. There are also secondary reasons why this type of work is carried out. For example, the house does not correspond to the urban planning concept.
The procedure for performing work on dismantling buildings
The process of liquidating buildings within the city is associated with the risk of damage to nearby infrastructure and the risk of injury to others. For this reason, technical documentation is developed and agreed upon. The very first step is to obtain permission from local authorities to demolish the building. Next, you need to find performers who have experience in performing similar work and special equipment. Some owners believe they can handle the demolition themselves. This is not recommended. Professionals should be involved in such work, as this process is complex and dangerous. Specialists will be able to carry out liquidation taking into account all factors and ensure the safety of people, nearby houses and equipment. The work is carried out in several stages: planning; preparation; destruction; garbage removal.
Stages of Emergency Dismantling
Due to the complexity of dismantling work, a plan for its implementation and technical documentation are prepared in advance. Permitting documentation from local authorities is also collected
The first stage is studying the construction site
Each construction site has its own characteristics, so before demolition it must be studied so that the work proceeds quickly and without difficulties. Experts evaluate the condition of the building, find out when it was built and from what materials. The results of the survey are necessarily recorded in a technical report, on the basis of which an engineering project is developed.
The second stage is preparation
Before the demolition of an emergency facility, must consider emergency demolition requirements and preparatory measures. They boil down to the following:
- installation of fencing in the form of a grid around the perimeter of the structure;
- turning off gas, electricity and other communications;
- conducting a preliminary inspection of the premises;
- clearing the area of debris.
- Only after completing the preparation can you move on to the main stage.
The third stage – dismantling the building
The building structures are carefully cut into individual slabs. They retain their properties, so after transportation from the site they can be used for other purposes.
During dismantling, various diamond cutting technologies can be combined. For example, demolition of internal walls is carried out using wall saws, and external walls – using rope systems. The foundation is most often dismantled using the rope method.
Stage four – removal of construction waste
During dismantling work, construction waste is generated, so after its completion, the area is cleaned. Construction waste is removed by special transport and disposed of. In some cases, it is sorted for reuse.
Conclusion
Emphasizing the importance of safety protocols and coordination among relevant authorities is paramount. Effective communication and collaboration between emergency responders, demolition experts, and local government agencies play a pivotal role in orchestrating a well-executed emergency demolition operation.
