Demolition workers are construction workers that tear down buildings or old structures. They clean away the old material and ensure that the area is safe and ready for new construction. As a demolition worker, the duties involve operating heavy equipment, using large tools such as wrecking balls and bulldozers and essentially demolishing buildings.
In some cases, smaller parts of the structure are taken down by hand. When this occurs, the team will need to survey and find out the best possible way of salvaging any materials. Then the demolition begins. Rock Tools breaks down more about demolition.
What Does Demolition Work Involve?
Demolition is arguably the most interesting aspect of construction. When new structures are built, the old ones need to be demolished to make way. This can be due to being old, or simply to build something better.
In the process of demolition, you are dismantling a building by pre-planned or controlled methods. Although it may seem like demolition is swinging wrecking balls and knocking things down, there are specific protocols in place to work with debris, weather conditions, materials, mass, and physics.
There are a few variables and steps involved before demolition is executed. These include:
- Survey: Experts examine the different parts of a building and survey the situation. This might include the materials, building usage, method of construction, condition of the building, traffic around the area, neighboring communities.
- Removal of hazardous materials: It is essential that any dangerous materials from the building are removed prior to demolition. This might include asbestos minerals, radioactive substances, even flammable materials, or petroleum. This ensures there will be no explosion or release of chemicals into the air.
- Plan: The plan is then made by experts to know exactly what will be involved and how it will be carried out.
- Safety measures: All site workers, supervisors, operators, and engineers will be briefed of any possible danger, and the demo company must have the correct permits.
Types of Demolitions
The Implosion Demolition
Known to be the most impressive or “fun” part of demolition is the implosion. These are usually less than 1% of demolition projects. Implosion is the process of blowing out the building’s supports using explosives. This can be dangerous and must be taken with extreme caution.
The Excavator Demolition
When it comes to smaller buildings like homes and offices, an excavator may be used to take down the structure. This is considered a cleaner, and safer way to dismantle structures. It is better for reducing dust and debris, as well as noise.
Wrecking Ball Demolition
An iconic picture in your head may be the wrecking ball demolition. These balls of steel usually weigh up to 12,000 pounds. It is placed suspending on a crane and swung into buildings. The precision is essential as it cannot be controlled once released. They are inexpensive but somewhat dangerous.
