Demolishing buildings in urban environments may have unintended implications and serious safety issues. Thus, planners for urban environments should take the time to carefully consider best practices and other considerations when making demolition decisions.
Alongside safety issues Demolitions are also environmental damage. Particularly, the debris from demolition can pollute local water supplies and decrease the capacity of sewers.
Challenges
Demolishing a structure may be an arduous procedure. It’s usually accomplished by taking out walls that are not load bearing or support structures that are weak and installing explosive charges. The entire process can take weeks and is a meticulous process to protect the buildings around. Furthermore, it can be difficult to remove large structural elements like columns and beams without damaging nearby buildings.
Aiming to enforce an agenda for demolition is not suitable when a large portion of the area is occupied and well-maintained, and the energy efficiency gains are feasible (Power, 2006a). Demolition is also a way of taking the existing buildings away instead of tackling specific problem houses and is not compatible with the model of incremental renewal that would benefit these neighbourhoods in the long run. A’scalpel’ approach to demolition is one that only targets the most risky and non-salvageable house, is more feasible (Mumford and Power 2002). This method of deconstruction also reduces the amount of embodied energy required in the property that will be replaced.
Safety Concerns
Workers involved in demolition and excavation have to deal with many hazards to safety, like weak structures which could fall at any time during the process. Additionally, these structures could contain dangerous substances hidden in the construction process like asbestos PCBs and asbestos and lead paints, as well as mould and even dead animals, like bats, pigeons or rats.
Apart from structural stability additional safety threats include falls from height and dust and fumes. These hazards can result in grave injuries or even death in the event that they are not taken care of.
Another concern is that demolition methods could cause damage to neighboring structures and even public places. Experts have created strategies like building explosions to minimize this risk. These methods involve using explosives to destroy the structure quickly and without causing harm to adjacent structures. It is also possible to install protection structures like debris nets and catch platforms in order to stop the falling material from hitting individuals below.
Limited Space
Many cities are turning to mass demolition as a means to improve areas and spur expansion. But, some critics say this strategy is ineffective and may lead to racial segregation. In addition, it may cause a decrease in the value of neighboring properties.
One of the most important aspects in the process of demolition involves the recycling or salvaging of building materials. It can lower costs and help save money for the city. Using material handlers, a demolition company can put the steel and other components into organized piles and then move it to another area to be processed.
This type of machine can make sure that the work is done quickly and efficiently. It does this because it is able to modify attachments according to various tasks, such as getting concrete or agglomerates. It is also able to sort and reuse steel, thereby saving the most valuable resources.
Environmental Regulations
The process of tearing down older structures could have significant ecological consequences, mua xac nha xuong particularly when it’s not done with care. As an example, vacant land usually produce huge amounts of stormwater runoff that is absorbed by nearby streams and the bodies of water, collecting contaminants in the process. It can affect local drainage and water quality, as well as decrease sewer capacity.
If asbestos-containing material are discovered in construction, they must be removed in accordance with federal and local guidelines. The result could be a significant increase in expenses for the project.
Furthermore, the emerging concept of circular construction holds the potential of providing an additional dimension to demolition plans. The process will need to be re-evaluated for demolition waste for reuse purposes and could change tendering procedures and plans for structural technology. This will be a challenge for both demolition firms as well as urban planners.
Public Relations
Skyscrapers soar high above the cities of the world. They are glittering symbols of power and prosperity. Sometimes, these gigantic structures don’t last long enough or suffer damage and are forced to be destroyed.
Instead of blasting them to pieces and smashing them using a wrecking ball engineers are working on more sophisticated methods to take down the massive buildings. In Tokyo the city that has several buildings with cheeks-in-jowls, engineers have developed what is described as secret demolition. Instead of blasting an entire construction at the same time instead, they’re removing it on the inside before taking the structure apart floor-by-floor. This technique can also be used if the structure is severely damaged and cannot explode securely. It’s much more quiet and safer than traditional wrecking ball. This is one of the easiest methods of destroying large buildings.
