The most common are shears, shredders and hydraulic hammers. The arm equipped with tools pulls down and breaks the structure from top to bottom. Then, special ground equipment uses hammers, sledgehammers and shredders to reduce parts to rubble. The correct pen size will depend on the building.
You can demolish a stone wall with a mallet, and it's quite easy to level a five-story building with excavators and wrecking balls. But when you need to tear down a huge structure, for example, a 20-story skyscraper, you have to take out the big shots. Explosive demolition is the preferred method for demolishing larger structures safely and efficiently. When a building is surrounded by other buildings, it may be necessary to implode the building, that is, to cause it to collapse in its footprint.
At best, there's noise, dirt, dust, and the usual urban pests. Add to that the construction of a new building next to or near yours, and the hassle can quickly become overwhelming. Obviously, the owner of the property under construction has the right to construct his building within the parameters permitted by local zoning and other regulations. But what about the neighbors? What can they do to preserve their sense of peace and home in the midst of a process of noise, boom and noise that can easily last for months, or even years? While efforts to protect you and your neighbors are available and advisable, the reality of living next door to an active construction site is still there.
Increased noise, dirt, dust, vibrations, traffic, pests and vermin, and some level of general misery are inevitable. In addition to a licensing agreement, other plans must be made to protect you and your property during the demolition and construction period. Perhaps the most obvious and persistent side effect of a long-term demolition and construction project is noise. In the city center, you're more used to noise to begin with, but in a more suburban environment, construction noise can become more noticeable.
Often, it all comes down to what a city's noise regulations are. In residential areas they tend to be more stringent. If the noise occurs during an acceptable period of time set out in local regulations, there is nothing you can do, as they comply with the regulations. Dust and debris are as present in demolition and construction projects as noise.
As they demolish an existing building, they continue to moisten it to minimize dust. They can also use fabrics to protect the area. Irrigation is the most efficient method.
