The term demolition is used when a structure has to be torn down. This is done for a variety of reasons. Often people will need to tear down a structure to make way for a new one, or to improve the quality of the space that the old one took up. When this is the case, it’s important to understand what demolition is and how it works. In this article, you’ll learn about the different types of demolition, how they are done, and how you can take precautions to avoid accidents during the process.
Methods of demolition
A demolition is a process of dismantling a building. This is usually done to make space for a new building. However, it can also be done for recycling.
Demolition methods differ depending on the type of structure being demolished. Typically, tall structures are demolished from the top down. But some shorter buildings can be dismantled from the bottom up.
Wrecking ball demolition is a common method of demolishing concrete buildings. A wrecking ball is suspended on a crane’s cable and is swung into the structure. It weighs about 13,500 pounds and can crush a building’s structure with repeated blows.
There are three other demolition methods. The most common is mechanical demolition. Using hydraulic excavators, heavy machinery or hand tools, steel and other metals are broken apart. Steel debris is then placed in separate piles.
Mechanical demolition is typically used for commercial demolition projects. This type of demolition is relatively quick, but can be expensive.
Implosion is a more dramatic technique for large, high-rise buildings. It uses explosives to destroy primary vertical supports of a structure. Depending on the size of the structure, the process may take weeks or even months.
Other methods of demolition include demolition with lances and non-explosive demolition. Both methods require careful consideration to ensure safe demolition.
Interior demolition involves removing certain portions of the building’s interior. Typical interior demolition includes removal of walls, ceilings and pipes. Selective demolition allows builders to reuse building materials.
In a building that contains asbestos, demolition can be dangerous. Before beginning a demolition project, asbestos abatement or remediation may be necessary.
To avoid damage to surrounding structures, demolition crews investigate construction details. They are then able to prevent accidents and avoid causing additional damage to the demolition site.
In areas with a high population density, a more environmentally friendly method of demolition has been developed. This method uses computer controlled hydraulic jacks.
In the case of an old retail center, it could be reused as a housing estate. However, it would need to be dismantled first.
Costs versus benefits of demolition vs deconstruction
Deconstruction is the practice of salvaging building materials from a destroyed structure for reuse or resale. This process can have some serious environmental benefits.
The deconstruction industry is relatively new. It is estimated that deconstruction could replace residential demolition in the US. In addition to saving money, it can also be a green way to build a house.
Demolition, on the other hand, is a less labor intensive process. To perform a traditional demolition, you need to hire a contractor. You’ll need to shut off utilities and prepare the site. A professional contractor will be able to check electrical outlets, HVAC units, and plumbing pipes.
However, demolition is more expensive than its predecessor, deconstruction. A study by the U.S. Environmental Protection Agency found that the total cost of deconstruction for a 2,000 square foot home was between $4.50 and $5.40.
While there is no hard and fast rule, deconstruction is generally more environmentally friendly than demolition. Materials such as roofing, siding, windows, and concrete can be salvaged. Salvaged items are more valuable than their original price because they can be used again.
Although there are some disadvantages, it’s difficult to deny the environmental, social, and financial benefits of deconstruction. For example, it can help reduce construction and demolition waste and help keep your community a more livable place to live.
Also, deconstruction offers many tax benefits. These include a tax credit of up to $100,000. And, the IRS allows you to carry these deductions over five years.
There are many other advantages to deconstruction, including the creation of jobs and the ability to recycle and repurpose used building materials. By selecting the right buildings and materials, you can even save yourself some money demolition contractors Atlanta GA.
If you’re thinking of renovating or rebuilding your home, consult with an architect to determine whether or not deconstruction is a wise investment. Some people prefer to combine demolition and deconstruction to maximize savings.
Regardless of your choice, there’s a good chance you’ll be able to reuse the materials that are left over from the demolition. Not only can you repurpose the materials, but you can also resell them for a profit.
Safety precautions to take during demolition
If you are working on a demolition project, there are many safety precautions to take. You must follow statutory regulations and the best practices. This can reduce the likelihood of injury and a flash fire.
A few of the common hazards include material falls, dust and noise. Proper equipment, training and communication are essential to ensure a safe job. The safety precautions to take during demolition are not always obvious. However, knowing the best practices and following them is the first step to preventing accidents.
It’s important to wear the appropriate PPE, such as hard hats, gloves and respirators. Noise reduction headphones are also useful. When you are inside a structure, brace for falling debris and use safety devices such as ladders.
Before demolition can begin, it is important to secure the site. All floors should be marked and guardrails to a height of 42 inches must be installed. There should also be a clear pedestrian path.
You may need to provide special equipment for workers to perform the job safely. They might need bracing for ceilings, walkways or other structural components.
Another good safety measure is to install warning devices that notify the public of danger. The most effective warnings will be displayed clearly and in a well-lit area. Ensure the safety measures you implement are backed up by regular inspections.
Safety should always be your number one concern. During demolition, you might encounter hazardous materials such as asbestos and lead. Make sure to inform the Occupational Safety and Health Administration (OSHA) about any of these materials.
If possible, avoid demolition work during storms. During the demolition process, you should use wet methods to control dust and other harmful substances. Also, don’t conduct your demolition at night.
The best way to protect yourself during a demolition is to hire competent employees. An experienced worker will know which safety procedures to implement.
Demolition is an extremely dangerous job. To reduce the risk of injuries, it is important to have a comprehensive demolition plan. In addition, a site manager must monitor the workforce to ensure they are following the rules.
Demolition insurance
If you are a demolition contractor, then it is important to get the right insurance to protect yourself and your business. Insurance companies have developed special products and programs designed specifically for the demolition industry. A professional will be able to help you decide what type of coverage you need and find the best deal.
Demolition work involves the use of explosives, heavy equipment, and cranes. These can all be dangerous. Workers are at risk of injury and even death. In addition, the work can expose them to serious fire and explosion risks.
Demolition contractors should have both general liability and workers’ compensation insurance to protect their business and their employees. Both policies can cover the cost of legal fees and medical expenses incurred during an accident or injury. The cost of these policies will depend on the contractor’s business needs, the amount of coverage the contractor wants, and the financial strength of the insurer.
While the standard public liability policy will only cover claims resulting from negligence, demolition and deconstruction insurance is designed to provide protection against common claims. Policies will also cover property damage, including repair and replacement costs. It may also pay for the costs of hauling away debris.
The most common claims are property damage, injuries, and personal injury. Property insurance will cover damages to the building and its contents. Injury claims will cover medical bills, hospital bills, and legal expenses.
Worker’s compensation insurance covers the medical expenses and lost wages of an employee who is injured on the job. This coverage can be used for short-term or long-term conditions.
Some insurance companies may require the local authorities to declare a property unsafe for use or repair. Before finalizing a demolition project, most contracts include inspections of the structure. If a structure is declared unsafe, the insurer will pay to remove the property.
In addition to public liability and workers’ compensation insurance, demolition companies can also obtain a comprehensive commercial property insurance policy. This coverage is designed to cover everything from the use of heavy equipment to the damage resulting from the operation of these devices.
