The area where i am supervising was sloped and we had to cut at upper slope and fill at the lower slope in order to make a leveled area. during the excavation of trenches the trenches at the filled area was dug deeper compared to the upper trenches to meet the hard strata. Now my question is, is it really necessary to increase the length of foundation column or can we increase the depth of RRM layer below the foundation pad to maintain the same length of the foundation column?
