What Is The Procedure For Building Demolition?

Buildings and structures must be demolished for a variety of reasons. Building and other structure demolition methods and processes are detailed. Every design of a building or structure, as we all know, has a lifespan known as design life. The structure is designed to last for at least 80 to 100 years. When the building’s design life is up, it is no longer safe for people to live in or for adjoining structures to be in. So, what is the procedure for building demolition?

 

There may be other causes for a building’s demolition, such as the need to replace existing structures with new ones. The structure has lost its stability or has been damaged structurally. Small constructions are dismantled to make way for larger structures, and so on. Demolition is a term that refers to the act of destroying, breaking down, or removing anything. Building demolition is the process of dismantling or destroying a structure after it has served its useful life by pre-planned and controlled techniques. Implosion is the term for when explosives are employed in the demolition of a structure.

 

Building Demolition Process

 

# 1 Surveying of Buildings for Demolition

The term “surveying” refers to the examination of several parameters of a construction and its surroundings. There are primarily two forms of surveys that are carried out.

 

A. Building Surveying

The following procedures are followed while surveying structures for demolition:

 

Materials used in construction

Prior to demolition, the structure was in use.

 

The presence of wastewater, hazardous materials, toxic chemicals, combustible or explosive materials, and radioactive materials, among other things.

Conditions of drainage, as well as potential issues with water pollution, flooding, and erosion.

Facilities shared with next building, including common stairwells and partition walls.

Traffic conditions for pedestrians and vehicles in close proximity

The neighborhood’s sensitivity to noise, dust, vibration, and traffic effect.

 

B. Structural Surveying

The following processes are involved in demolition in structural survey:

The construction method

Basements, subsurface tanks, and underground vaults have structural systems and conditions.

The structural system that was used in the initial design.

The state of the structure.

 

# 2 Removal of Hazardous Materials

If hazardous materials such as asbestos minerals, petroleum contamination, or radioactive metals are discovered during the site investigation for destruction, the site will be demolished. Hazardous materials must be removed from the site before the structure can be demolished, which necessitates the use of specialized personnel.

 

# 3 Safety Measures during Demolition of Building Structures

The possible risks and demolition procedure are explained to all personnel, site supervisors, and engineers, as well as plant and equipment operators. All flammable items are removed from the site unless they are required for the work. All flammable goods, such as wood, timber, and fuels, are kept in secure storage areas. Until the demolition is finished, firefighting equipment is stationed at the site. Workers encounter numerous issues as a result of the destruction of structures, including dust exposure, chemical exposure, heat stress and ventilation, noise exposure, medical and first-aid facilities, sanitation, and occupational diseases. Appropriate efforts are taken to address these issues.

 

# 4 Building and other Structure Demolition Methods

A. Non-Explosive Demolition Method

It refers to the deconstruction of a structure using only equipment and no explosives. The following are some of the several types of demolition equipment that are employed: sledge hammer, excavators and bulldozers, wrecking balls, and high reach excavators.

 

B. Implosion Method of Building Demolition

The building is made to fall like a tree to the side in this sort of implosion. This is the most prevalent form of implosion. This sort of demolition is recommended when there is free space adjacent to the building. If there is open space on the building’s left side, the explosives are placed on the lower level of the building’s left side columns. As the bombs detonate, the columns burst, and the structure begins to topple to the left. To restrict the direction of the building’s fall, steel wires are fastened to it.

 

As you can see, demolition is not an easy task and requires planning and equipment. For professional demolition of buildings, you can contact Farache.
