Surge IV is actually a series of temporary buildings (TB 200 - TB 203). They are located across the parking lot from the Silo and across the street from Hutchison Hall. The Engineering Dean's Office (Scholars' Center) and Vet Med dean's office are here.
Surge IV is recognizable from its very 70's style covered courtyard and wooden deck. The cover is by no means waterproof, which makes it rather interesting when it rains since it has all sorts of random slippery deck locations and localized downpours.
