In just over 18 seconds the three-wing, 220,000-square-foot residence hall will become a pile of rubble.

Opened in 1965, McCollum initially housed 910 students. It has been the king — at least in size — of KU’s Daisy Hill dorms ever since.

Demolition preparations began last month. The work has included removing and hauling off all soft material such as wood and sheet rock, and removing tons of metals for recycling.
