The Hyatt Regency McCormick Place in Chicago has begun work on a $110 million expansion and renovation project. The first phase, which began yesterday, will include construction of a new 460-room tower that is expected to be completed in mid-2013. The second phase, beginning this spring, will include a redesign of the property's coffee shop. Phase three, to begin late this year, will include the expansion and renovation of the main lobby, the existing 800 guest rooms and the hotel's 25,000-square-foot conference center. Phase three also will feature an expansion of the hotel's fine-dining restaurant and the addition of three boardrooms. The property's function space currently totals 55,000 square feet.
