The 400,000-square-foot addition includes two multi-story masonry structures on both the east and west sides of the stadium; the end zones will remain open. The structures, which will stand 10 feet higher than the current scoreboards at their highest point, include 83 suites and 3,000 club seats.
When the renovations are complete, the capacity of the Big House will top 108,000.
The plans call for buildings to be constructed on the concourse at the north and south end zones. These buildings will house additional restrooms and concessions, and support functions such as first-aid, police/security and will-call. The structures will be covered in the same brickwork as the new sideline buildings.
Stadium improvements will include an increase in the number and quality of restrooms; more concession stands with a greater variety of fare; wider aisles; handrails; additional entry and exit points for improved crowd circulation and safety; and additional dedicated seating for fans with impaired mobility.
Construction work will be phased over a period of three years in order not to interrupt home football games. It is expected to be completed prior to the 2010 fall football season.
