Though I haven't jetted concrete sheet pile in dense sand, I have jetted concrete piles into dense sand on Extended Island, N.Y. The primary difficulty we seasoned was from more than jetting to try and reach the required suggestion elevation. The jetting process in sand forces the supplies to segregate among the sand and stone which makes up the stratum.

Columns may not be constructed on shallow foundations Foundation reinforcement with micro piles subject to undermining by nearby scour and erosion (2021 IRC 322.three).
I'm unfamiliar with the expression "study system" to work out plumb. My experience is similar to that of your geotechnical engineer, the place a four-foot degree is employed to determine plumb deviation from vertical (on H-piles). The extent is ready in opposition to the pile and plumbed vertically, plus the hole concerning the pile and the tip of the level not touching the pile is calculated and claimed, alongside with the compass path from the lean (e.
