The last unfinished floor of Building 303 at the Brooklyn Navy Yard is set for a major overhaul — one officials say is poised to shape the future of deep tech jobs in New York City. The Navy Yard Development Corporation (BNYDC), in partnership with the New York City Economic Development Corporation (NYCEDC), announced Sept. 23 that it is seeking design firms to redevelop the ninth floor of Building 303. The organizations are encouraging locally based enterprises as well as minority- and women-owned businesses to apply for the project. The 9th floor of Building 303 was once intended for a single office tenant, but will now be adapted to host multiple growing businesses. The Navy Yard said submissions “should include a brief project approach, proposed timeline and subcontractor list.”
