Demolition is the process of tearing down a building. Deconstruction, on the other hand, is the process of reconstructing buildings. If you compare demolition vs. deconstruction, deconstruction is not a popular practice and costs approximately twice as much as demolition. However, homeowners can offset this expense by donating salvaged building materials. Still, the extra time and expense can be a deterrent for some. Learn to know about Demolition and Deconstruction Different.
What is a demolition?
Demolition is the process of removing a building. You can do it for many reasons, such as health or safety. It can also be done to eliminate toxic materials. For instance, a building could be made of asbestos, which is carcinogenic when disturbed. Consequently, an arbitrary demolition of an asbestos-filled building would have adverse effects on the environment and people nearby.
There are legal requirements to follow when demolishing a building. The first of these is to secure a demolition permit. You can get one from your local government. If you are not experienced, you can hire a demolition contractor. These professionals have the training and experience needed to safely and correctly perform demolition projects.
When looking for demolition contractors in Pheonix, AZ, it is important to choose a company with a solid reputation. You should check out their previous projects and see if they are certified or licensed. In addition, you should check if they are insured. Having the right insurance coverage is essential when removing buildings.
Demolition vs. Deconstruction
Demolition and deconstruction are two very different methods of tearing down structures. While demolition is the faster, less expensive option, deconstruction can take up to twice as long and cost more. Some homeowners offset the cost of deconstruction by donating salvaged materials, but the extra time required can discourage some people.
Both processes can be dangerous, and they come with their own set of risks. Demolition dust is a common source of respiratory problems, and workers with asthma may even end up in the hospital. Deconstruction is a better option because it prevents the accumulation of hazardous materials, which can spread and affect workers. Additionally, deconstruction rather than demolition offers many benefits, including the potential for workforce development and improved safety.
While demolition may seem like a better option for a smaller-scale project, deconstruction is still a good choice for a large-scale project. Not only does it keep materials from landfill, but it also reduces the carbon footprint. While it’s a better option for the environment, deconstruction is often time-consuming and expensive.
Why choose deconstruction rather than demolition?
Deconstruction has a number of benefits. For example, it helps to keep the building’s contents and structure in good shape. Deconstruction also helps to reduce the amount of waste. There is also much less effort required on the part of builders. In addition, deconstruction can help increase the brand value of a building.
Another advantage of choosing deconstruction rather than demolition is that the materials used to build the structure can be reused. These materials can be used for home renovations or donated to non-profit organizations. Furthermore, you can use deconstructed materials to construct new buildings or houses, or they can be sold for profit as building materials.
The other main advantage of deconstruction is that it helps reduce the construction waste that goes to landfills. According to the National Waste Report 2020, construction and demolition contributed 27 million tonnes of waste in 2018-19, which is 44% of the core waste stream.
Deconstruction can reduce greenhouse gas emissions from construction sites by diverting materials from landfills. For example, a typical single-family residence contains about 6,000 board feet of lumber, which is equivalent to 23 million BTUs of embodied energy. This amount is equal to the energy needed to drive an SUV five and a half times around the world. This waste can be reduced or reused by reusing materials, extending the life of these materials.
Regulations for Deconstruction
In cities and towns, regulations for choosing deconstruction rather than demolition can help encourage recycling, prevent hazardous materials from ending up in landfills, and prevent the unnecessary destruction of historic buildings. Some jurisdictions have deconstruction ordinances that require certified contractors to dismantle structures. Historic deconstruction may also require special permits.
Before deconstruction, a duty holder must assess the risk of falls from heights. The presence of microbes and bacteria is another potential hazard. A premature collapse of a structure may result in injuries to workers. The deconstruction process must follow a specific sequence to avoid this. Electricity, gas, and water must be disconnected before demolition work begins. Also, they must clearly label telecommunications cables to prevent disruption.
Conclusion
The EPA defines deconstruction as the process of dismantling a building to maximize the number of salvageable materials. Deconstruction contractors adhere to the same health and safety regulations as demolition contractors, but their demolition vs. deconstruction methodology varies. They must ensure that materials are source separated because co-mingling building materials can cause environmental problems and pollute landfills.
