I have a bridge footing supported on 24" diameter steel pipe piles. The bridge is a grade crossing (no water) and the footing is below finish grade, so the piles will have lateral support from the soils for their full height. The piles do not experience any tension.
Is it typical practice to provide a reinforced concrete plug at the top of the pile? Or just sand fill?
