A memorandum published in connection with the Academic Center/Williams bond (pdf) states on A-9 and A-10 that the North Campus Academic Center will replace Gilman and Dana, is scheduled to begin during July of 2013, and is expected to be substantially complete by March of 2016.
The building is planned to house the Departments of Sociology and Anthropology (the college was mum about this in an article in The Dartmouth, and the plan might still be in flux); the Center for Healthcare Delivery Science; the Institute for Health Policy and Clinical Practice; Dana Biomedical Library; and the administration of the Geisel School.
Elsewhere, it is noted that the Academic Center is a registered LEED project.
And what about the bridge to Kellogg — will it survive? It could be hidden behind the screen visible on the left side of the image published here recently.
