We are working on an existing warehouse building in San Francisco area. The building was built in 1930s and founded on timber piles. So far reviewing of as-built information does not provide us with pile length/pile tip elevation. Pile quality is another issue. A majority portion of each pile is under water, and about 3 feet of the pile length is within the water fluctuation zone. The portion within the fluctuation zone raises our concern on the quality of piles. To provide the geotechnical capacities of the piles, we have to find the pile tip elevation and if the piles are structurally sound. Anyone has worked on the similar project? Any good idea or technology to do so? We are considering exposing certain piles to observe the pile conditions, but maybe limited by access and the extent that we can go. Responses are appreciated.
I did not figure out how to reply to your response. So I am trying to write this message by folloing up to my own posting. Hope you will read it and get my message.
Thank you so much for your information and your nice offer. Surely I will appreciate if you can provide me with the key elements to access time pile quality. MY email address is firstname.lastname@example.org. I haven't got the chance to check out the website you mentioned, but do that asap.
