Deconstruction
One of the services we offer is ‘quiet’ demolition. In other words – element-by-element taking down of buildings and construction structures.

In order to ensure correct deconstruction of concrete and reinforced concrete buildings and structures without causing environmental damage a comprehensive approach must be employed. One also can’t do without help of dismantling professionals and specialized machinery. One has to calculate required load, determine deconstruction timeframe, and allocate workforce. The main task of deconstruction is not only to break regular and reinforced concrete and also to clean up the area and remove huge quantity of waste left after deconstruction.

Deconstruction can be broken down in several phases. First, ruberoid and linoleum products, heating pipes, plumbing fixtures, and metal structures are taken away from the building which will be taken down. Then, the building is taken down using manual or mechanized method depending on building type. The final phase is waste management (the waste is sorted out, loaded onto dump trucks, and taken to recycling sites).

Mechanized takedown is one of the most widely used deconstruction methods which involves use of specialized heavy machinery. It is the most civilized method of tearing down when buildings are dismantled, one may say, ‘without much noise and dust’. Mechanized teardown also involves removal of demolition waste. Of course, specialized machinery is required for deconstruction projects. If we are talking about reinforced concrete structures (i.e. concrete with durable rebars incorporated in it), hydraulic shears will be simply indispensable. These shears can not only cut steel reinforcement but also carry it to another place. Shears will gripe the demolished object by opening their jaws. The wider opening is, the larger piece shears can grab. These shears are usually of compact size for manipulation convenience. Also, all materials simply must be highly durable and wear-resistant. Pneumatic and electric tools are used in the case of semi-mechanized deconstruction method: rock breakers, crowbar shovels, concrete breakers.

An element-by-element deconstruction method is also used for dismantling projects (which involves manual labor). This is the slowest method but ecologically the safest. Deconstruction of reinforced concrete structures may be broken down in the following phases: block-by-block separation begins with opening up of reinforcement, then blocks are fixed in place, reinforcement is being cut, and the block is crushed. Metal elements are cut off immediately after unfastening. If reinforced concrete structure cannot be separated by elements, it will be taken apart as a monolith.

Implosion is also used for demolition purposes. However, this method is seldom used, which is understandable: any miscalculation during implosion may cause irreparable damage to the environment. Use of this method is prohibited in the immediate proximity of residential buildings.

Diamond sawing/diamond drilling is a very expensive method. It is used for partial or complete deconstruction of reinforced concrete structures. Currently, a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings is no longer used for dismantlement purposes.

Apparently, selection of dismantlement method and specialized machinery depends on the number of factors: building type, gas supply system, engineering networks, water supply lines. But one thing is obvious: a comprehensive approach must be used for deconstruction.
