I live in a townhouse with 5 apartments, now they have started excavating for a house on my neighboring lot to prepare for piling next week.
These damages have occurred after the excavation:
Post that holds the roof. Other side of the post, you can clearly see that the plaster is indented here. Here you can see that the outer wall has moved outwards 5-6mm.
A different room on the upper floor.
There are more issues, cracks in walls, silicone in the shower room that is coming loose, etc.
Vibration meter mounted outside on 16mm frogolit with threaded rod into the foundation.
It has recorded, if I remember correctly, a maximum of 2.2mm/s, as they have made a risk assessment that sets the limit value to a maximum of 3.5mm/s, it feels like they are not taking my concerns seriously as they are far from the limit values.
I would have been worried if the outer wall moved 5 mm. Then regardless of what their threshold says, I would have ignored it if that happens in your house.
I informed them about this today, they have been to look at new damage that has occurred this week three times, but still they proceed as if nothing has happened.
