^^^I heard it's actually due to complete in 2021, but you're close.
Site work is being done for both towers, so I would assume structural foundation work will begin for both towers simultaneously as well. As for the towers, I believe it is possible to construct them simultaneously. The shorter tower may go up quicker, since it is much less complex.
