Would someone be able to estimate unit costs for a sheet pile design i have? This is a permanent retaining structure on a lake where i would backfill behind the wall with gravel and construct a concrete walkway over the gravel (walkway is for pedestrians so not load bearing). The calculations were done with assumptions about piles driven in sand with granular backfill. I designed a 14' total height sheet pile with 6' depth of penetration. wall length is about 450 linear feet. i calculated the maximum moment to be about 5 kip-ft and then a section modulus around 2.05 cubic inches. Was afraid the section modulus was too low (sheet pile might face problems with bending?) so i increased it to 10 cubic inches (the thickness of the wall would also increase which would improve resistance against rusting). Based on this i chose a SZ-15 section (I am using cold rolled sheet pile). Would anyone know approximate unit costs for the sheet pile and maybe delivery costs? I'm finding $40/linear ft in places but wanted to make sure. Also, does anyone have recommendations about type of gravel i would use and then maybe unit costs for that?
