Need suggestions for possible friction piles
(OP)
Hello, I have a job in Kearny, NJ with deep loose sands and silts. Traditional wood timber timber don't provide enough capacity for this heavily loaded building of over 1000 PSF. Does anyone have any suggestions for other friction types of piles?

I don't have any information posted on my website on concrete piling, but see Section 4 of "Bethlehem Steel H Piles" on this page http://www.slideruleera.net/Steel-Piling.html

The electrode can also be lifted to create multiple "bulbs" to give more skin friction further increasing its capacity.
Think of it as a Franki Pile on steroids!
I can forward you the name of the company that has imported this technology for further reference if you are interested.
This is an extremely cost effective solution.

GBIDS - I would definitely be interested in the name of the company for more information.

I don't have the phone number handy but you can most likely find it on the web or by calling directory assistance.
Having seen the technology first hand it is really exciting - it is actually written into the Russian Building Code and has even been used for underpinning of historic landmarks in St. Petersburg.
Jerry will have more info I am sure.

Based on their preliminary chart, you should be able to get capacities in the range of 7000 psf with granular soils at 7BPF.
You may also want to price out removal and recompaction to a depth below footings. I have found that to be economical in some instances, where space permits.

The site includes loose sandy and silty soil, yet several of the methods suggested may cause vibrations that could result in settlement damage to nearby utilities or structures.
Steel H-piles don't seem to be a good idea because as low-displacement piles, sometimes they "run" during driving. It seems obvious that if there are no vibration issues, using a displacement pile to maximize the end bearing resistance would be appropriate.
I have to get on the soapbox for the final comment. This site is an excellent place to get a variety of opinions on geotechnical issues, but an open-ended post like this always makes me wonder if these discussions pages are really a good idea after all. Presumably, Mahlegreco is working with a geotechnical engineer with the appropriate experience to direct this work, and is simply looking for more information to support the process. However, without some statement confirming this to be true, I have to wonder if it is even appropriate to even respond. Geotechnical engineering can't and shouldn't be done anonymously without knowing all of the facts. Site conditions like those described really require someone with the right local experience, not just for technical reasons, but also to understand local contractor issues etc.
