From 2000 to 2015 I believe most of the other buildings on campus were refurbish. Funding for those buildings was always "found" somehow. No one I talked to on campus at the time could figure out how that was happening every year. The athletics department for sure was not thrilled about the funding allocations going on. I knew a few good people who left UNI because of those "games" to go to work for other schools. UNI couldn't afford $1000 for practice jerseys but could afford a $40 million renovation to some administrative building.
In the end, I think Price Lab and one other staff office building were the only ones torn down. The gym was 15-20 years old when they tore the rest of the school down (2014?). Price lab was torn down for politics. I was told back in 2005ish that Cedar Falls City Govt and UNI officials wanted to build a new CF HS and move it onto UNI's campus and basically create a new lab school that tax payers would have to pay for and support. Uni would still get to run its weird teaching experiments, teacher development programs, and have majority administrative control over the school. It turned out 15 years later that that was actually true. The new CF HS is being built by the UNI Dome on the old soccer fields.
Back on topic, Price Lab's gym, locker rooms, pool, training/fitness area, bathrooms, concession area are still intact and very usable. UNI has repurposed the gym 2 or 3 times now since Price lab closed and was torn down. They easily could have pushed volleyball and wrestling to there. The track and field team likely still uses the running track and field next to the gym.
UNI has always been run by morons and narcissists. It is an open joke on campus amongst "rank and file" staff.
