we excavated to 5 feet and remove the loose fill and the strata at this elevation is a virgin ground with single digit blow counts. the game plan is to fill it in 12 inch lifts with RCA and compact it to 95% of maximum dry density. how you determine the bearing capacity of the compacted recycled material and how far below the surface the load will impact the fill.

After you do all this you would then consider the settlement response of the "safe" bearing pressure. Unlikely that the settlement in the newly-placed fill will amount to much, but the soft clay may be a different matter. If settlement is too great, then you'd have to further limit the bearing pressure. Bear in mind that you would want to consider settlement via soil modulus and ALSO one-dimensional consolidation coefficients.
Hope these ramblings help.
