Chicago-based engineering firm Sargent & Lundy has expanded the massive anchor-tenant lease it signed at 77 W. Wacker Drive last fall.  The company leased an additional three floors in the office tower, about 66K SF of space, on top of the 380K SF it had formally agreed to lease last December, Crain's Chicago Business reported. Sargent & Lundy's total footprint in the tower is now almost 448K SF, or about 60% more space than its previous home at 55 E. Monroe St.
