Gensler, CH2M HILL, and AECOM Technology Corp., have been named the top three architecture firms in the world, according to Engineering News-Record. For the third consecutive year, Gensler grabbed the No. 1 spot. CEO Andy Cohen says 2013’s success can be attributed to the consistent designs the firm provides to an increasingly interconnected and global world. And consider this nugget: The combined total architectural revenue from the Top 300 firms jumped from $10.01 billion to $11.20 billion, according to writer Zachary Edelson.
