After spending more than half a billion dollars on construction in Foggy Bottom, GW could now be a major player in development projects across the city.

Two real estate firms have included GW medical and biological science facilities in their pitches to rebuild a more than 60-acre site in Northwest D.C.

Those companies are among three developers vying for the former Walter Reed Army Medical Center property, which sits between Georgia Avenue and 16th Street. The teams presented their ideas Thursday, and Mayor Vincent Gray will have a final say on who develops the site, the Washington Post reported.

One proposal, called “The Parks at Walter Reed,” would include GW and the Massachusetts Institute of Technology lab facilities as well as Hyatt hotel and conference center and an arts center. Also called the Hines-Urban Atlantic proposal, it would take about 10 years to complete.

The second was pitched by Roadside Development, and includes a partnership between GW and Howard University. It would also include retail, housing and a hotel.

Associate Vice President of Operations Administration John Ralls said he could not immediately provide information about the plans.
