I'm going to have to guess that this project is moving that much faster than Fan Pier, basically because this is being built in the middle of an already developed street grid. Whereas Fan Pier is a 100% new development. On top of all new site utilities, Fan Pier is also excavating right on the waterfront to throw down some underground parking. The time for excavation is greater than normal underground parking based on the need for water containment slurry walls to go in before pouring for garages.
2 Financial doesn't seem like it went down far at all, just a typical basement or 2. And, as for utilities, all they had to do was tap into the street utilities and they are done.
Hopefully this spring/summer will give us some actual "development" over at Fan Pier though. It'll give me something to look at on my lunchtime walks. Or something to pretend I'm looking at instead of all the girls dressed for the weather.
