I have a site that will have 7-feet of dense gravel fill over 6-feet of soft sands (liquefiable) over native gravel at about 15-feet total. It may be hard to auger through the fill as it has cobbles. I'm considering micropiles, drilled shafts, geopiers, CFA piers, or whatever else would work best. I have had a hard time finding any comparative cost guidelines. For example, I suspect micropiles are more expensive than geopiers (in general) but just don't know. Does anybody have anything? Also, any thoughts on what concept would work best would be appreciated.
