It appears our friends at engineering firm Buro Happold, which just moved their offices to Downtown Los Angeles, are experiencing some of their own moves. Chief engineers Greg Otto and Sanjeev Tankha have taken their talents to Walter P. Moore, a Santa Monica firm hoping to expand their design expertise and research capabilities. In other moving news, after ten years wHY Design’s founding partner Yo Hakamori has left the firm for DesignARC. And over in New York our friend Dung Ngo has announced he’s leaving Rizzoli. No word why at this point, but according to Ngo the parties are leaving “on the very best of terms.” If only all breakups were as amicable.
