Miscellaneous Musing #53: MM #52 Follow-Up

I've another question about Newtown's plan to raze the Sandy Hook school and raise a new one upon its ruins. (Yes: There is a pun on "raze" and "raise".)  Where will the children who would have gone to the current edifice get their education while its replacement is under construction?  Except for igloos, tents, and the occasional lean-to, no building that I've ever heard of has gone up in the under-three-months that the town has left before the onset of the next academic year.
