How much time do they expect the seats to take to install.. in theory you could remove the east seats once fball is over? What do we have like 40 rows in a section? This isnt really an issue of time, its one of effort? if the plan was to have 3 guys working 4 hrs every other evening, then re think the plan.
I would assume that cranes have to go in? But you can for sure take out the benches without need cranes you could walk those things out the concourse.
We dont really even know of the new seats get installed, it could be a strip goes down they bolt into? or each seat could require some drilling ?
Are they doing it on the cheap so the crew size is small?
