41. Are the 18” PSC pile battered at 4:12 (legend on drawing S-100) or 5:12 (drawing S-301)?

With a pile cut off elevation minus the tip elevation there’s a vertical difference of 103.95’ and the pile length appears to be 109.57’L for 4:12 batter or 112.61’L for 5:12 batter. Can you confirm the pile lengths on drawing S-601 with the correct batter?

The 18” PSC piles are to be installed on a 5:12 batter. Refer to revised Sheet 601 for the updated pile schedule.
