Damages due to driving Wood piles
Damages due to driving Wood piles
(OP)
A new house is being constructed next to my client. They drove piles in the rain and crushed the pile tops. Piles were as close as 15' away. Reported damages consist of cracked concrete driveway and walkway. Both houses are on the water in a sandy location. Client's house is constructed on piles. Crawlspace slab appears to have cracked along foundation walls.
No monitoring was conducted during pile driving. Is there any literature discussing damages in order of expectations. eg glass breaks before wood before concrete. My other concern is the vibrations may cause the soil to consolidate under the driveway and crawlspace slab. Is pile driving different than blasting damages?
Thanks

Also..the rain is irrelevant.

1. The damage was not present before the pile driving occurred - can you document this?
2. The damage was noted during the pile driving process - is this documented?
3. After the pile driving was stopped, are there subsequent pictures where a progressive damage can be seen between points 2 and 3?
4. Was the pile driver or contractor notified of the damage, but kept driving pile anyway?
5. Did you ever notify the local building department of the damage during the pile driving process?
6. Could the piles have been overdriven (crushed pileheads), to the point of transmitting a different frequency to the soil matrix?
7. If there was a chance of this occurring, I have no idea other than cost, contractor expertise, or equipment availability why an augercast system was not used instead.
