A pair of landlords in New York and Washington, D.C., are turning to Am Law 100 firms to serve as key tenants for two buildings now under construction.

Morrison & Foerster and Covington & Burling are poised to move into the new office towers; MoFo in a 40-story building being developed by Boston Properties at 250 West 55th Street in midtown Manhattan, and Covington in a massive mixed-use project called CityCenterDC being developed in downtown D.C. by Hines, Archstone, and The First Investor U.S. Real Estate Fund.
