Cornell has a handy FAQ page for this project, and there’s now a project schedule to go along with it (embedded below). Bids are due in September with contractor mobilization in early November. It says the windows on Goldwin will be boarded up to protect them from rock blasting, so I imagine this is the major component of excavation to get the land along East Ave. lowered to the proper grade. The concrete retaining wall along East Ave should follow the excavation.
