I gave up at about 11am and left for the day – the noise and vibrations were horrible.
As I understand the max vibration today was 1.15mm/s. They tell me that 5 mm/s would damage buildings and 3.5 mm/s would trigger an alert to tell them to stop
Noise levels peaked at 76dB, well under their predictions.
They expect 5 more days of it.
They had told us that the jackhammer would have a noise shroud but they now have discovered that the shroud does not work with this jackhammer
