    Foundation Works

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.

Silent Piling by Press-in Method

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. For the Silent Press-in Method, a sheet pile is clipped andpressed underground. Even for harder ground, noise and vibration can also be minimized by pressing-in sheet piles with simultaneous augering, by the Gyropress Method.Construction work can also be completed in shorter duration by using this method so that the noise impact to nearby NSRs can also be further alleviated.
