7 feet of soft soil
7 feet of soft soil
(OP)
A 500 foot long by 50 foot wide area has approx 7 feet deep soft saturated fat clay. It is set to receive 13 ft of fill and hold up some small structures and possibly a parking lot. Our preliminary recommendation is to over excavate and replace the 7 feet of soft material. Any other cost effective ideas?

I am assuming your "soft matl." is a lower P.I. soils? If the heavy fatty clay is a big worry, you could Lime treat it about a foot thick, then begin your fill.
I have seen 10+ ft. of fill bridge a multitude of bad stuff. Once you start your fill,I would not over compact or vibrate too much until at least a few feet of new material is in place ( you might pump up some moisture etc.)Shoving a 3-5 ft lift across this area initially might be the way to go before you begin to compacting.
Good Luck

I assume the soft material is at/near the surface. What is below? Where is ground water? Is the material suitable for reuse? Can it be properly conditioned during the construction period?
