What can cause a building to collapse?
Unfortunately, errors on the part of architects can lead to devastating failures of the building after construction is complete. Some collapses can be attributed to a failure to account for real-world conditions, such as high winds, the effects of icing and thawing, and the high salinity of sea air.
Is this the most effective way of demolition building?
Implosion is by far the most impressive method of demolishing a building. However, due to their specialized nature, implosions are used in less than 1% of demolition projects. Implosion is the process of using explosives to knock out a building’s main supports, causing the building to collapse from the inside out.
How does Controlled Demolition work?
In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings.
What are the different types of demolition?
