In my area, the sequence is to drill the soldier piles, drill the dewatering wells, draw down the water, then excavate.

I suppose in some areas, it may be preferable to draw down the water and then drill the soldier piles, but where I am the contractors are content to drill in wet ground with segmental casing.
