The project reaches a milestone—Substantial Completion—as the contractor officially turns over the building to the Museum. Landscaping begins but is interrupted due to extreme conditions of heat and drought.

As exterior construction nears completion, East Building gallery finishes are installed. In the Main Building, 18 reimagined galleries have opened. The St. Louis community anticipates a mid-2013 grand opening of the new Museum Campus.
