Technical Aspects On The Demolition Of Buildings

Demolition is a story made of passion for earth moving operations, excavations, demolitions and transport of materials for third parties. The demolitions company has been working to better meet the needs of customers, regardless of whether it is a company, a private individual or a public body to request our services.

Relying on specialized companies because?

The demolition of civil and industrial buildings (Office Strip Out Melbourne  ) is among the activities of the construction sector with the highest level of risk. This is why it is important to rely on companies specialized in carrying out this work.

In the last 30 years there has been a considerable increase in the renovation work, with more or less extensive demolitions, of the building park. The factors that determine this situation are numerous and the following can be identified as having the most relevance: – aging of buildings; – less availability of building areas in the city center; – social and technological progress that renders many existing buildings obsolete; – disposal of previously industrial areas; – renovation of industrial plants; – building renovation projects.

Environmental regulatory constraints

It is the case of the vibrations induced by the demolition operations (Office Strip Out Melbourne ), the control issues of the emissions in the surrounding environment of dust and noise that disturb the environmental quiet of the neighboring area.

Demolition methods of civil buildings or industrial buildings

Selective progressive demolition

It proceeds with the controlled removal of parts of structure, keeping the remaining parts statically efficient. This methodology is typically used in cases where the space of operations is very limited. This is the case of the removal of internal partitions, false ceilings, structural portions, internal service networks.

Deliberate collapse

It proceeds with the removal of key elements at a static level in order to cause complete or partial collapse of the structure. The latter must therefore be statically disconnected from the part that is free of demolition. The technique is used when the space surrounding the structure is sufficient to allow such operation safely.

Removal of elements

The demolition of structural parts is carried out for deconstruction and disassembly.

Executive aspects of the demolition of buildings:

Demolition of buildings for the whole structure or partial demolition of buildings.

The demolition is carried out mechanically with:

  • Demolishing presses (for cement and / or metal)
  • Crushing pliers
  • Hydraulic hammers mounted on excavator arms.

Mechanical demolition

Most of the demolitions occur with the use of specialized machines: from small ones suitable for indoor environments, often radio-controlled if in hostile environments, up to large machines equipped with special crushing or cutting tools. The choice of machines takes place in relation to access availability and maneuvering spaces. In large spaces it is often the use of high-reach excavators for the demolition of structures of considerable height, or of demolition excavators for structures that are less vertically extended. For particularly high structures, a technique known as flying demolition is often used, which involves the use of a demolition insert suspended from the arm of a crane.

When demolitions (Office Strip Out Melbourne) are to be performed in urban areas, a technique called top-down or floor-by-floor is used, which consists of the use of small and medium-sized machines and manual tools for the controlled demolition of structural portions, floor to floor on the ground or at a level suitable for ground demolition machines, typically demolition excavators. Some structures can be easily demolished by cutting into segments and cutlery on the ground by using cranes or loaded on transport vehicles. This is the case of metal pylons, overhead tanks, prefabricated or steel lattice structures. In hostile environments, such as for example in industrial furnaces or in the presence of highly dangerous materials, it is common to use radio-controlled machines equipped with special demolition tools.
