We know that South Carolina has been updating the video board at Williams-Brice Stadium.
Apparently South Carolina has also been working on improving the field at Williams-Brice stadium. The past few days they have been adding sand to the natural grass field.
Honestly I have never seen sand added to a grass field before, but I assume it is to help with drainage.
Here is a photo:

South Carolina is also working on a large 52 acre tailgating area, which will be landscaped with over 650 trees and will feature a 100 foot wide pathway that the team, band, and cheerleaders will walk through as they enter the stadium called the “Garnet Way.”
