The west expansion of the McCormick Place Convention Center featured Epstein leading a 25-member design team, which delivered this 2.5 million-square-foot, $882 million facility on-time and on-budget.

Epstein directed the design and engineering team and ensured that the design intent documents developed by TVS Design was executed accurately in the construction documents produced.

Additionally, numerous design and/or engineering concepts were developed during an intense value engineering consolation with the MPEA in which Epstein's architects and engineers were able to design modifications to TVS' conceptual intent, resulting in over $300M in savings for the MPEA.

Specifically, the west expansion is bordered by Martin Luther King Drive to the east, the Stevenson Expressway to the south, Cermak Road to the north and Indiana Avenue to the west

The West Expansion includes approximately 459,000 square feet of exhibition space, 140,750 square feet of meeting/banquet space, a 103,750-square-foot ballroom, as well as associated food and support service spaces.

This expansion enabled the McCormick Place Convention Center to remain the largest exhibition facility in the United States.
