In 2012, a client reached me to get to a shoring solution for an excavation.
'Shoring' is a civil engineering technique to retain the earth in deep excavation.
The Client requested a cost effective solution to support 7 m of earth in a deep excavation. I provided two options with cost comparison.
1. Driving of steel sheet pile
2. Soldier piles.
Option -2 was economical and technically feasible. owing to existence of deep sandy layer in the sub soil profile , the driving of sheet piles predicted to be difficult.
