It was mentioned that the contract states that the construction on the east side of Elwood/University can start any time the contractor wants (after July 1, the start of the fiscal year, I assume).
The work on the west side has to wait until after the season.
I’m no construction engineer, but if it’s me I’d want to get as much work done before students arrive, and then having to start planning around fan traffic in September, as possible.
I would guess that at the very least, they'll want to get footings poured on either side of University before winter.
