Therefore, it is the primary responsibility of any contractor to check that no neighboring building or infrastructure is affected. Building demolition service includes single family homes, large apartment buildings and others.
- Scrap Metal: As recycling is a part of several projects they will haul steel structures, process them onsite and haul away for recycling. This process is known as scrapping metal.

The Demolition Methods
Demolition is a process which requires a good knowledge about buildings and its construction process backed by the technicality of using equipment required in the procedure. These methods vary according to building material, location, disposal requirement and techniques and most importantly your ultimate demolition goal.
- Mechanical demolition: This method is used frequently for any average demolition. This process involves knocking down the building using different mechanical tools like: cranes, rams, bulldozers, excavators or a wrecking ball. The ideal objective is to break down the entire structure into smaller pieces. These pieces are then sorted to be recycled or discarded. It sometimes involves undermining and weakening the internal supports of a structure to encourage collapse.
- Implosion: This method involves wiring structural supports. These are strategically planted so that after explosion the weight of the building while falling causes its own end. This process is extensively followed where buildings are in packed condition. It is also used to demolish massive structure to cut down time. These structures include smokestacks, tunnels, towers and bridges.
- Deconstruction: This is another method that is done manually and often takes as much time as to construct a building. This process is followed only when the materials obtained will be repurposed in future for other projects. This process is considered eco-friendly.
This is another specific type of demolition service provided by the contractors. For this monolithic hammer, extended booms, swing wrecking balls and crushers are used to break down the walls. These structures are often more than 20 meters tall for which a telescopic boom is required to reach to those heights. A lot of planning is required to ensure success in such demolition. Inspections and surveys must be done for asbestos, reinforced concrete and any other exotic materials. A lot of large refuse collecting skips are also required by the company to clear the material waste that is considerable in such cases.
Plaster wall removal service is another type of demolition service is implemented when multiple rooms are present, and the building is to be demolished partially. The structural shell must be preserved though every floor, wall and window frame are on the way to refuse skip. The contractor must consider asbestos insulation, utility lines that must be disabled, sewage lines and lots more.
Therefore, demolition procedures are to be carried out entirely by professionals and safety protocols are to be strictly followed to avoid hazards and risk for both workers and the society.
