Demolition Contractors Sydney

Demolition is not just about smashing things down. It’s about smashing things down in the right way. If you need to ensure proper and safe demolition at any site from start to finish, you need A to Z Demolition, the Sydney demolition experts.

Bringing down buildings safely requires planning and coordination. It requires some understanding of how the building was constructed, what is contained within the building, the materials that were used, and many other factors.

A demolition company you can rely on

Not all demolition contractors in Sydney are equal. Experience and knowledge are vital attributes for a demolition company. This is how you can decide if you can trust the demolition contractors to safely undertake the task of demolition and removal from your site.

A to Z Demolition is one of the most trusted names for demolition in Sydney. Clients know they can rely on us to safely deconstruct any structure, because we have expert demolition staff who know everything there is to know about how to bring down buildings correctly.

Here’s why it matters

Imagine you were tasked with demolishing a building that was previously part of a CSIRO research facility. What would be your first step? If your idea was to jump in a crane and start swinging a wrecking ball Homer Simpson style, the scenario would not be likely to end well.

Demolishing any building professionally involves studying the plans of the building and getting an in-depth understanding of exactly how it was constructed. Furthermore it is necessary to know about chemicals, gasses, and other hazardous materials that may be present in pipes or other parts of the building.

For example, some older buildings may contain asbestos. Demolishing these buildings requires special precautions to be taken. Simply knocking them down without taking the proper care could result in a local environmental disaster.

That’s just asbestos. The kinds of gases that might be present in a CSIRO facility could cause environmental damage on much more than just a local scale. Explosions probably wouldn’t be out of the question either.

So you can see demolition is actually sometimes quite a delicate job, requiring demolition workers to operate with skill, sensitivity, and constant situational awareness.

Controlled demolition in 3… 2… 1…

When demolition experts talk about controlled demolitions, they usually mean bringing down structures with the use of strategically placed explosives.

Here again, it is not just a matter of piling in explosives and making a big bang. The explosives need to be placed and detonated in a logical sequence, allowing the building to collapse inwardly and safely, rather than blowing chunks of flying concrete, steel, and glass all over the neighbourhood.

Controlled demolitions should be timed in such a way that the key load bearing points collapse layer by layer from the top down. It should look kind of like a wedding cake collapsing in on it’s own centre.

This type of demolition is normally only used with very tall structures, to provide the most economical means of demolishing them. For ordinary structures, it would be exceptionally uneconomical to use explosives, and that’s even if the local council would allow this demolition method to be used at all for an ordinary structure.

Technically the correct name for controlled demolition is “building implosion”, and that name suggests the opposite of explosion. Thus the job of a demolition engineer during a controlled demolition is to create an implosion and prevent an explosion.

Deconstruction is the best demolition method

Although it is slower than other methods of demolition, deconstruction is the least wasteful and safest way to remove a building from a site. From an environmental perspective, this is by far the best method because it greatly reduces the amount of material that will end up in landfill. Most materials can be salvaged, and some of those that can’t be salvaged can still be recycled.

Even though it is the best method, it’s not necessarily the method everyone will choose. It really depends on your objective. If you want to remove the existing structure as rapidly as possible, deconstruction is not for you.

A to Z Demolitions is ranked in the top echelons of demolition companies in Sydney because we operate with the utmost safety no matter which method is chosen. We also can help you decide which method to choose based on your specific demolition objectives.

Don’t forget about the clean-up

Knocking things down is just the first stage of a demolition engineering job. Another crucial component is removing the shattered remains of what was once an architect’s pride and joy, now reduced to rubble and rubbish.

Responsible and swift disposal is what you want. The site should be left looking as if there never had been a pre-existing structure erected up on it. That is essentially the core of an effective demolition project. If nobody can tell that a building previously existed on the site, then the building was entirely removed, every trace of it.

You can be certain A to Z Demolitions will always provide a top notch demolition job, and will clean up the site for you so it looks brand new.
