If you're not an engineer some of the calculations may escape you, but don’t worry the video explains all the calculations in one go!!

Something to cheer up the Engineer in you. Just to put you in the picture and keep you up to date with the latest developments.
Below is a link to a short video of a Pakistani pile driving construction technique!

The chant is also catchy!
Now, let's analyse the Engineering here:
6 men x 180 lbs = 1080 lbs static force.
Jumping up and down will create a 3 times dynamic effect = 3240 lbs/jump = 1.6 ton thumps if the pile is tapered to 2 in x 2 in, cross section at the tip = 4 sq. in. So, dynamic pressure/thump at pile tip = 3240/4 = 800 psi.
"Add a man" feature will increase to 950 psi, so buy the option!
Increase the chant and dynamic force goes up to 5 times to bring max.
pressure / thump to 1600 psi for a 7 man team.
Quite good, and will penetrate hard clay and sandy soil (but not hard or rocky ground!) Pretty ingenious.

Oh, the foreman is the guy on the tambourine.

Fantastic.

This one's higher still. All I can say is they must have good balance - I'd fall off

Gotta forward this one to our project engineer at work

He'll say "Wow! What a cool idea. This will save us on safety boots, PPE, expensive hiring of mechanical devices!"

The ground must be very soft. No wonder they need all these piles, and I'd still worry about subsidence.
I guess they dig a hole to get the pole started so it is straight and able to support them to start with.

Second one is Thailand

Do they use spiked pogo sticks for roadworks, instead of jackhammers?

Very clever, them Thais'

Just when you thought it couldn't get cornier!!

You think that's bad?... check out what I did to Brock here...

Yep saw that. I stayed out of that thread once it went down the gurgler.

I wonder..... Do they get paid stamp duty?
