I spent so many years as a child imagining how they did this! It’s good to finally know how it’s really done.who else watches these videos not because you do this for work or because you need to know it but because you are actually interested in it.Human ingenuity has never failed to amaze me, I mean everything from thinking of a solution to building the pile driver.This is so complex. Thank you to the civil engineers who do this work.This is the best engineering channel by far. Straight to the point, very educational, clear explanations and graphics. Well done my friend
