If you making your mind to undertake the procedure of Demolition, then you must know whole a lot about the process. This article will tell you all in detail.

What is Demolition?

Throughout the world, people encounter constructions built by man: buildings, works of art and civil engineering, traces of the past preserved or protected, but also modern works. Today, for any structure, you speak easily of "lifetime". Introduced in recent decades, especially with insurance obligations, this concept is clearly displayed with the concepts of sustainable development and the "life cycle". If the lifetimes of the works, it is noted and must be satisfied, can be measured in centuries, the guarantees provided by builders in a building do not generally exceed 30 years when they reach more than 100 years for some works of art. Demolition Services in Melbourne in needed in many cases.

The end of life of construction can intervene either by "natural" aging, because of the degradation of the constituent materials, or because of a weakening of its structure (lack of design, lack of maintenance, accident, natural disaster); the work becomes unsuitable for its use, even dangerous.

But the end of life can also be the object of a decision without relation to the state of the work, for example during urban renewal operations or equipment modernization. In one case as in the other, it is necessary to resort to the demolition of the structure.

Demolition, deconstruction, what is it?

Demolition is the process of dismantling or destroying a structure, using planned and controlled methods. The technical term used today is "deconstruction", which integrates not only the demolition but also the selective sorting of the components of the structure. The principle of deconstruction is written which obliges the building owners to take into account the management of the waste of which they are at the origin. This circular has allowed in recent years to redirect the demolition sector to deconstruction. The concept of demolition only covered the landfilling of waste; now, with the deconstruction, you can value the waste by their possible reuse.

Taking into account the entire life cycle of materials and allows to give a second life to the waste that represented in the country. Demolishing a building is not easy, and requires, after selection of the most suitable methodology, preparation and provisions rigorous operating.

You can also distinguish:

  1. Total demolition,
  2. Partial or selective demolition, internal and/or external, with the preservation constraints of the conserved parts.

In all the cases, the subjections are numerous:

  1. Preliminary diagnoses for specific treatments (asbestos, lead, wood pests, etc.)
  2. Securing the surroundings and the neighborhood,
  3. Operator safety,
  4. Prevention of pollution (noise, dust, effluents),
  5. Sorting and recovery of waste in the approved sectors.

What regulations for demolition?

The permit to demolish: Before starting a project of deconstruction (total or partial), it is generally necessary to file an application for a demolition permit with the municipal administration on which the site concerned depends. The permit to demolish has a validity period of 3 years; it can be extended by two times a year.

It is mandatory in two situations:

a)If the land is within the perimeter of a "protected area" (according to PLU or building listed as a "Historic Monument"),

b)Or when the municipality established it by deliberation.

If the demolition is followed by construction on the same site, then it is called a building permit worth demolishing.

A)Only a few people can apply for the permit to demolish:

B)The owner of the land (or co-indivisaries),

C)A person who has received authorization from the owner,

D)The leader of the exploration of the land for public purposes.

Before the works, it is necessary to know the state of the various networks present at the right of the work and inside the work (electricity strong currents and weak currents, gases, water), and to ensure neutralization. During deconstruction work, the area concerned must be closed in order to prevent any intrusion, the external road must be protected and the inhabitants and passers-by must be informed.

Different methods of demolition/deconstruction:

Demolition Company Melbourne provides different methods of demolition, chosen in function of the characteristics structure's demolition:

  1. Its location and its environment (urban site or other),
  2. Its structural composition and its state of stability,
  3. It's volumetry.

And you will not talk here about explosive demolition, which requires very specific skills and know-how.

Manual demolition: During a manual demolition the building is felled starting with its high parts. The demolition is done as and when, from top to bottom. This method is used when the object is to reduce the height of the building without demolishing the foundations, or if one seeks to make a partial restoration rather than a reconstruction. To carry out a manual demolition, in addition to the appropriate hand and mechanical tools, scaffolding and tarpaulins must be installed in particular. Another method of manual demolition is undermining, which involves demolishing from the bottom up. The building is destroyed by attacking the foundations first. Too dangerous, sapping is no longer practiced.

Mechanical demolition:

Demolition with a shovel: Demolish a hydraulic excavator building can be done either:

a)By pulling the work, and then we talk about demolition by shovel pulling,

b)By cutting (and/or clipping), by "crunching" the concrete as it goes.

A shovel bucket is ideal for demolishing load-bearing walls and any building blocks or bricks. The bucket not only plays the role of demolisher but also allows to load the bucket with the waste produced. For security reasons, the demolition is done from top to bottom. In other cases, the excavator is equipped with a concrete crusher. A scrap shear can replace the concrete crusher to cut metal structures. A sorting clamp completes these specific tools and allows a more precise deconstruction and refined sorting.

The brokk: The brokk, named after the company that invented it, is a very powerful remote-controlled demolition machine on tracks and stabilizing feet.

The "brokk" is usually equipped with an electric motor, guaranteeing work without exhaust fumes and reducing noise. The operator who controls the remote is positioned outside the scope of action of the machine. This equipment makes it possible to carry out demolitions when the accesses are complicated or present particular constraints.

Cutting demolition: Cutting is a very accurate method of demolition, which mimics rubble projections, and prevents vibration up to neighboring buildings. Cutting demolition can be carried out by sawing the structure or making close perforations. Synthetic diamond tools are used to cut hard and thick materials; diamond-set tools are adapted to softer materials. The cutting can also be done by projecting a jet of water under very high pressure; this is called hydrodemolition.
