All of the structural components are prefab and made to order. Think about all of the giant overhead beams for the NW Corridor project. They've been working on that for a couple of years now, and they're just getting all of the structural pieces in place.
And that's with planning.
Don't they just need to replace like 6 concrete columns? I know I'm missing something but it just doesn't seem like it would need to take that long.

The columns have to be formed and poured, then they have to cure. The weight of the concrete on itself strengthens it many times over as it compresses and contracts. Putting excess weight on it prematurely weakens the integrity of the columns.
