The vibration from the Metro Tunnel work was particularly bad over the last 48 hours. I called the 1800 number plus contacted people I knew at CYP.
I understand that they have been within the approved limits but I stressed that I felt it was extreme.
Tonight this email should have come to people who have their emails registered with CYP
Good evening Botanica Residents,
I just wanted to send a quick note to let everyone know that we are aware that vibration levels experienced today in the Botanica from 1pm until the end of shift have been particularly high.
We have a vibration monitor attached to the Botanica, which is showing some of the highest levels since we started the d-wall works in the southern box, however I can assure you that these vibration levels are still below the levels where we would be concerned about any damage to the Botanica building.
Irrespective, this evening we’ve called in our contractor to investigate options to mitigate the vibration, as we understand for those residents at home it has been particularly disruptive. They have attributed it to the ground conditions in this particular section.
From start of works tomorrow around 7:00am, you’re likely to experience similarly high vibration levels until 9am, at which point the team is going to switch from the Dwall ‘grabber’ to the Dwall ‘cutter’ for the remainder of the panel, which will generate less vibration.
Given there are still a number of panels to be completed in front of the Botanica, we’re exploring what we can do for the future panels to minimise the vibration from the grabber being used, as we cannot excavate the panel exclusively with the cutter.
If anyone has any specific concerns about these works, please respond to this email – or call the 1800 number and I’ll get in touch.
