Completed on a fast-track schedule, the existing Baltimore Convention Center was kept fully operational during construction of the new expansion. The $160-million expansion consists of a 750,000-sf (70,000-sm) addition that tripled the size of the original building. The new facility includes a below grade, 300,000-sf (28,000-sm) exhibit hall, the addition of 45,000-sf (4,200-sm) of meeting rooms, and a new 36,000-sf (3,300-sm) ballroom, plus accompanying mechanical public spaces.  An innovative three-chord truss system created a 180-ft x 600-ft (55-m x 180-m) column free exhibit space in the exhibition hall.  

The project was awarded the 1998 Grand Award for Engineering Excellence by the American Consulting Engineers Council and the 1998 Diamond Award for Engineering Excellence by the New York Association of Consulting Engineers.
