How Demolition Crews Carry Out The Risky Exercise Safely
Posted by: Matthew G Smyth / Category: EnvironmentEvery once in a while it seems that city officials get their act together long enough to pass judgment on beyond decayed beyond repair. Once the verdict is out there is usually no turning back and the demolition crews are sent in to clear the eyesore off the face of the earth. Sometimes the building might be structurally sound but might have violated some zoning or other law. In some instances the proprietors might have a grander vision for the lot than earlier imagined and additions to the already existing building are not an option.
The why is not really the concern of this article but the how is what we are interested in. Demolishing a small structure or wall might only require a sledgehammer and a little brawn but bringing down a skyscraper in the middle of a city is a totally different issue. These operations usually require intense planning and impeccable execution.
There are architectural plans to be pored over with a fine tooth comb and a physical examination of the building to be carried out. In most cases these assessments are carried out more than once just to be on the safe side. This process alone takes a couple of weeks at best.
Effectively leaving only rubble that is then easily carted off leaving not a single trace of the edifice that once stood at that spot.
The easiest job is usually where there is an empty lot next to the building onto which it can be toppled. This is sort of like felling a tree. Explosives are placed strategically on the side of the building it should topple onto once this side is compromised the rest of the building leans in that direction and comes tumbling down. This is usually done in phases depending on the size of the building.
The planning phase of these operations is usually months in the making. Especially if the area is heavily populated and there are sensitive installations in the vicinity. All manner of permits have to be obtained and the time of the explosions have to be specified down to the last second so as not to raise the wrong alarms.
The day of the demolition is one of the most nerve-wracking for any demolition crews who have to once more go through the motions of double checking to ensure everything goes according to plan. The most exciting part of any of these exercises is the anticipatory feeling during the countdown before the building crumbles in a cloud of rubble and dust. The whoops of accomplishment are usually well earned!
Asbestos Removal These have to be followed strictly in order to maintain the health and safety standards. Your average person should not tackle the job of asbestos removal alone. This is to prevent any lawsuits from people that are exposed without prior knowledge of the work being done.
