If you ever need up-to-the-minutes status reports on the progress of Alta Roosevelt (801 South Financial Place) in the South Loop, look no further than Alta’s own Twitter account. They’re on top of all things constructive as Walsh Construction continues to work on the future 33-story apartment tower. Designed by Pappageorge Haymes Architects for developer Wood Partners, Alta Roosevelt will sport 496 rental units, 348 parking spaces, and zero square feet of retail.

There’s a lot of work happening at ground level. Here are a few pictures of the first floor taking shape, though I can’t get as close (nor as high in the tower crane) as the Alta Twitter account.
