Excavate a 5m x 5m x 5m pit with a mini excavator

I suspect that it will be a cistern or a gas/oil tank. Given the size, putting it in will be quite a challenge.

Mistake... the pool for a diving tower.

I suspect that it will be a cistern or a gas/oil tank. With that size, putting it in will be quite a challenge though.

he can borrow a small pallet truck... it has already been paid off anyway

if it's really just a cistern: wider and shallower and the garden shed is done a 5-meter deep hole is probably not at all proportional to storing water... or the thing will just be smaller...

Hi,

Even though the OP most likely won't respond anymore, because he simply wants to build *THE PROJECT* exactly like that and was also unwilling to be questioned.

I could go crazy every time,

I'll add to that: Anyone who believes that such work can be learned without accidents in a home cinema or with a note (quote from the first post)

Maybe there's a video that I haven't found, or some kind of instructions??

has a serious problem with self-assessment and overestimation. But that can't be solved in a forum. Either he gets the "Darwin Award" (Google helps), or someone knowledgeable helps him on site and prevents worse for the OP or his environment.

my 2 cents, Kermit

from the police report around the corner from me

What happened? The incident commander described the scene as follows: Currently, a construction company is building a biogas plant on an agricultural property. After an excavator had dug a trench about 3.50 m deep, a 25-year-old and a 39-year-old worker entered the trench to lay pipes there. During these works, the walls of the trench collapsed and the two men were buried by the earth. One was completely buried under the heavy clay soil, the other was stuck in the soil up to about nipple height.
