The new Food Sciences Building has completed a substantial amount of exterior work, although the glass facade has yet to be installed. The $105 million renovation is to be completely done in early 2014, with the new Dairy Bar sometime earlier than that.
Site prep is underway at Gates Hall (the new Computer Science building). The $60 million, 103,000 sq ft building is targeting a December 2013 completion date.
It’ll be a happy day when these plain beige boxes are removed. Unfortunately, the $51 million renovation of Warren Hall that necessitated their construction will not be complete until early 2015 (with the Dyson School portion complete by mid-2013 – and it annoys me to refer to the AEM Department as the Dyson School, as if the perceived pedigree was needed to remove themselves from the stigma of CALS).
Not the most telling image, but Rice and Fernow Halls are currently in the middle of their renovations.
This Bradfield-based photo of Fernow shows the partially-subterranean classroom being built on the east side of the building.

Great news on the Dairy bar- I will be able to come back a year after I graduate from Grad school and try it out- its been continuously closed since I got here. :*(
