Costs to build hangar?

[SoloEqs]

I think anyone with the least bit of welding knowledge and/or metallurgical processing experience and/or metal failure analysis would have to agree that doing such a thing is a scary proposition.

If it was actually done just right, then that was pure luck.

It has held up against gusts over 75 MPH and an earthquake centered 1.3 miles away. I'll take that kind of luck!

Not to mention the Portland Cement Association recommends a minimum of 7 - 14 days cure time for a slab

You're mistaking working days for calendar days.

Once again, I am talking about a 2,500 SF pre-engineered metal building with a concrete slab having a perimeter beam, not a pole barn type structure.

I'm talking about a hangar.

The question was whether a hangar could be built in a short amount of time, by a few unskilled workers. It can, whether you "buy it" or not.
