The below grade work is usually so slow because the concrete work is so complex and non-typical. Speed comes from repetition, when you can pull a form off of one pour and stand it up at the next one and pour again. The underground is usually filled with slopes, beams, stepped and thickened slab areas, etc. so you're literally custom building every form, then starting from scratch again on the next pour.
