Quite a lot.  The shelters must go up fast, withstand high winds.  Should be tall enough to stand up in and have insulation from the heat.

Here is a series of UTOOB videos showing Constuction and erection of these shelters.   All would apply in a disaster situation.

Dunno

Burning Man has quite the sharing community when it comes to shelter, cooking, gray water management etc.  The festival has been around a long time.

Just thought the shelter stuff would be of interest to some folks here.
