Yale has begun the construction of two residential colleges ahead of schedule, according to the Yale Daily News.
Though the project is scheduled to break ground in February 2015, workers have been on site for at least the last three weeks, said a construction worker on conditions of anonymity given contractual constraints to the Yale Daily News.
The project is funded by $500 million Yale received in donations, according to the Yale University website.
A single alumnus, Charles B. Johnson, donated $250 million to the project, the largest single donation the university has ever received, the press release added.
The expansion is scheduled for completion in 2017, and will allow Yale to accept 200 more students per year, said the Yale Provost Benjamin Polak.
Yale spokesperson Tom Conroy stated that the work currently being done is preparatory and does not constitute an official groundbreaking of the construction project.
