I'd be drilling a couple of 1" holes in the base of the roof and top of the wall frames and have some handy 3/4" bolts ready to drop through the holes when the university is in lock up mode or maybe put some tiedowns into the concrete slab and have some handy lengths of steel cable ready loop around the roof trusses and shackle to the cables so the roof stays put in this kind of even. Which seems to be very frequent the last few years.
Might do the second one (put some conveniently tiedowns in the slab when I get it down. Some bent reobar will do the trick.
