Hey DearBorn. To answer your question, construction won’t start on 2WTC until Silverstein secures an anchor tenant such as, Duetsche Bank or Amazon. Basically they need a company to commit to a lot of space in the building so they can immediately start making a profit off of it. Once they have this tenant they can begin building.
That being said, it’s not really a matter of finishing 3wtc first and even if we get a tenant we likely won’t see boots on ground until late 2017/early 2018
