Rem Koolhaas’s Office for Metropolitan Architecture and Thom Mayne’s Morphosis Architects are among the six firms that Cornell University is considering to design its high-tech graduate school on Roosevelt Island.

The finalists for the engineering and applied science campus, first reported by The Wall Street Journal, also include Skidmore, Owings & Merrill; Diller Scofidio + Renfro; Steven Holl Architects; and Bohlin Cywinski Jackson. Skidmore, which helped Cornell develop its initial proposal, will continue to work on the master plan.

The university expects to select a winner by April and to begin construction in 2015, with a tentative opening date of 2017.
