Company that would build underground Shooting lane on private property?

Big trench and connex shipping containers buried.

Don't bury Conex boxes. Bad things happen. They are meant to be stacked with the pressure on the edges - not over the center.

I want to see pictures of the failure. Assume less than 10' to top.

Thanks, I assume someone was driving on it??
Either during backfill or after. I've had crew members destroy corrugated metal pipe immediately after installation, but it will hold up for thirty years if it's not point loaded. It looks like the dirt is very wet too. That would add a lot of pressure.

I doubt anyone was driving on it.

These are built to carry the load very specifically, and when the load isn't in the right places, they fail very quickly.

Did the dirt get there by itself?

Second the bad idea to bury Conex boxes. Plenty of info on the subject across the net.
Use curragated metal or plastic drain pipes, they are much cheaper and resistant to crushing forces.

Of course not, however, back filling doesn't require driving on it...

Conex shipping containers are designed to carry the weight in the corners. The only real structural metal is the very corners of them. The walls and ceiling are 14ga corrugated steel.

Without significant reinforcement, 8' spans of 14ga steel cannot support the weight of dirt, whether it's light sandy back fill or otherwise.
