Helical screw piles for a pedstrian bridge foundation

[abih]

The subsurface consists of about 60 feet thick CL with isolated CH soils. We were talking about drilled shafts and recently the client is asking for helical pile recommendations. It seems to me that John Pack of IMR has compiled a quite informative guide for helical piles design. Are there any other authoritative reference available that should also be looked at as well? Thanks.

abih....About 15 years ago, I did a covered pedestrian walkway over swampy land (organic silt and sand) bearing on Chance anchors. Worked fine.
