Noise and dust from demolition sites can disrupt neighbors. However, there are many solutions to reduce the nuisances to ensure that the workers and residents can have a an enjoyable working space.
LEV stands for local exhaust. (LEV) Systems can help reduce the noise generated by demolition and masonry work through the filtering of dust and other pollutants that are breathed in.

Demolition works can be noisy and noisy, however there are a variety of ways to minimize noise to minimize the effect on neighbouring residents. In particular using the work daytime and restricting the use of noisy machinery to certain times of the day can assist in keeping noise out of the way.
Announcing to residents the schedule of demolishment can let the residents know prior to demolition about what is to be expected. An experienced contractor with experienced compliance records can assist in reducing complaints. Also, employing quieter equipment will significantly reduce the amount of noise produced by demolition. Obayashi’s Bubble Silencer, for example it covers the chisel used on huge breakers (heavy machines that crush cement) using bubbles to lessen the noise. It reduces the noise up to 5 decibels and removes up to 90% of the dust that is generated during demolition.
Dust suppression in demolition
The suppression of dust is a fundamental aspect of demolition as it can contain dangerous materials such asbestos, aluminium, and silicon crystals. These materials are hazardous to both the workers and those living nearby.
Prior to the start of work an area for demolition will be thoroughly watered down in order to stop dust becoming suspended in air. It is a good method, but it takes many workers to move the area and move hoses.
Some solutions are safer and better than others, such as making use of spray cannons to collect dust. Bubble Silencers cut down the sound of breakers by up to 5dBA. It is beneficial to the health of workers.
Acoustic Barriers in Demolition
Noise barriers reduce or block sound waves and help mitigate demolition noise pollution. They work best in areas that are near to the source of noise, or in areas that are sensitive to sound.
Also, you can reduce background noise using noise-reducing equipment or scheduling work to periods of quiet. In addition, it’s essential to check the level of noise regularly and make adjustments if necessary.
Hydrodemolition machines, such as the one above, could significantly minimize dust and noise during demolition of concrete. The hammers in the hydrodemolition equipment don’t have to be as powerful on concrete, unlike traditional breakers. The result is that they are quieter.
Dust Control in Construction
Dust is a normal and a challenging complication from construction work, particularly in the dry months. It not only irritates employees but also poses a serious health risk, leading to lung problems and even death in the event of frequent exposure. Dust poses a risk for biodiversity and wildlife if it is inhaled and makes its way into the waterways.
Teams have a myriad ways to reduce dust that is generated during construction. They can be grouped in three categories: engineering controls, administrative control, and personal protective equipment (PPE).
Controls in engineering include the use of sprays of water to reduce dust or the installation of local exhaust ventilation equipment. Administrative controls may involve changing plans for work, as well as limiting the duration and frequency of activities that generate high levels of dust. PPE is the ultimate line of defense against dust. It is comprised of respiratory protection and eyewear.
Deconstruction Site Pollution Control
Even though demolition projects generate huge amount of dust and sound, minimizing the impact on residents nearby can make sure that you are in line with local environmental regulations. You can measure the condition of the air continuously and adapt the work area according to it using the portable monitoring equipment that includes a dust and noise sensor.
Also, you should collaborate with a professional contractor. You will be less likely of your neighbor complaining.
It has been discovered that many of the pollutant levels aren’t measured in demolition areas, meaning it is impossible to assess them on a continuous basis. The latest IMS is a monitoring system for air pollution and vibration and noise pollution at demolition sites to make sure they are in compliance with regulations.
