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.

If I had some coin I would DYI. No permissions needed, just money.

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?

I'm a Mason and need a place to shoot. They even make sound deadening block that I've used on high school gyms to keep the sound to a minimum.

Look into box culverts, pre-cast concrete, made to be underground.

Precast pipe/culverts are probably more expensive in the end than just digging a trench and forming/pouring concrete walls and a ceiling in place.

Backstop, lighting, target mover and ventilation will add to the price.

As far as who would build it.. Pretty much any contractor could do the job if you had the design and specs laid out.

Consider water table and drainage as well.
