What do you do when there are not enough emergency exits/fire exits for a large rally? Add more! Big Ten Rentals supplied two sets of double glass doors to increase the capacity of the U of I Field House by 500 people. Usually these doors are offered as an option on our clearspan tents. We had to get a little creative. The biggest challenge was not being allowed to bolt or screw into the facility. We utilized the bollards that were already in places and added several thousand pounds of concrete ballast.
