The Henry W. Bloch Executive Hall for Entrepreneurship and Innovation, just north of the existing Henry W. Bloch School of Management, will open for classes Monday on the University of Missouri-Kansas City campus. J.E. Dunn was the lead contractor for the $32 million, 68,000-square-foot building with four floors of classrooms, meeting spaces, administrative offices and a 200-seat auditorium. The older business school building could accommodate a maximum of 80 people in its largest space, which limited the functions that could be held there. The school has about 1,800 students enrolled, up 70 percent from 2007.
