Commercial Demolition In Melbourne
A commercial demolition project is any commercial building marked for removal. It can range from anything from an old cinema house to a multi-story building of flats to a bank. Demolition in Melbourne is an ongoing process over the decades because there is not a lot of room for city expansion besides up or over the top of old and abandoned excavation sites. Hence, any commercial building In Melbourne that is about to be demolished can be big news. If you are planning to demolish a commercial building in Melbourne, there are lots of things to consider before starting the process. First, a demolition expert must walk through as much of the building as possible to see how and where the wrecking ball and/or explosives should hit or be placed, assuming the building cannot be saved and/or is too dangerous for others. The demolition expert is may advise you that it would cost far too much to save and renovate. It would be better financially to tear it down, rebuild and even remake a new building to look like an old one than it would to salvage a run-down building.
For commercial demolition projects a demolition expert has to obtain a permit to remove the building. The city council must approve the demolition in Melbourne based on structural findings and the need to remove the building. Following this they would then approve the permit so that the demolition company can move forward with the project. All power and gas lines to the building are turned off before the project begins. The demolition company will then attempt to tear down the building with the least disturbance, least danger to people in the immediate surroundings, and minimal debris. If the building is so unsound that many of its floors would result in harm to the demolition crew, it might be demolished using some explosives. These explosives are commercial grade, placed at key points within the first floor or sub-floor of the building. Charges are set and set off, dropping the building into a pile of rubble within minutes. Then the crew begins removing the rubble.
If the building is structurally sound enough, and/or it may not come down easily with explosives, then the demolition crew will tear it down using wrecking balls and backhoes with claw attachments. As chunks fall, they are scooped up and dumped into waiting tipper lorries. The tipper lorries haul the waste away to dispose of it elsewhere. If there is a sub-floor, then excavation of that sub-floor occurs last, removing all traces of the building and preparing the excavated hole to be filled in with dirt.
What Influences The Cost Of Demolishing A Commercial Building?
Several factors can affect the cost of the demolition of a commercial building in Melbourne. One major factor is whether asbestos is present. The older the commercial building, the more likely asbestos is present. Before such a demolition project can begin and the building can be removed, asbestos abatement crews have to enter to determine if the asbestos can be fully removed first. Once the asbestos can be removed, then the project continues. If the asbestos can't be removed fully, additional costs can be incurred because extra special precautions have to be taken to remove the building and preserve the health of everyone on the crew and everyone within miles of the building itself. As it stands, any of this dangerous material present means that the cost of the project can increase.
The size of the building is another important factor affecting overall costs. The larger the building in any one dimension increases the cost because it will take more time to break it down and remove. An old bank that takes up less than a city corner in terms of space is less costly to remove than an office building forty stories high and takes up nearly the length of an entire city street. Excavation may also be required to remove the foundation of a building if the foundation goes below ground, very common with large basement structures. An alternative to excavation is to just bury the foundation, but if the property owner intends to rebuild on that spot, then the buried foundation can become a problem therefore it is often best to remove it from the ground entirely, the whole exercise is costs dependent.
