A lot of foundation works involved noisy activities, such as excavation/site formation, rock breaking and piling works. Typically, sound power levels of excavator/loader, bulldozer, excavator mounted breaker and piling machines can reach about 112 dB(A). Quieter equipment or methods are commercially available, which can significantly reduce the noise emission from the foundation works.
Noise reduction for some mitigation measures for reference.
Foundation Works
Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.
An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.
Unlike explosive chemicals or expansive compounds, soundless chemical demolition agents do not produce vibrations, and hence, they are completely quiet and safe to use.
Silent Piling by Press-in Method : Traditional massive augering and piling machines for sheet piling work at hard ground condition would create significant noise and vibration impacts to neighbours.
QPME or Quality Powered Mechanical Equipment items, are construction equipment items that are new, notably quieter, more environmentally friendly and efficient.
Bursting system can be used for concrete breaking to replace traditional handheld percussive breakers.
