At a time when most contractors are wondering where they will find work for 2009, McHugh Construction's schedule is full, as long as their projects can secure the funding they need. David Alexander is the senior vice president and Dale Hendrix is the senior vice president of concrete field operations for Chicago-based McHugh. Together, they have helped to make the company the biggest builder of super-tall buildings in the U.S, building five of the top 12 on the list maintained by the Council on Tall Buildings and Urban Habitat.
