To my understand you would need at least two dynamic ropes as the swing and two additional dynamic or static lines. One static line would be packed away in a backpack that the person swinging would carry with them and would be attached to the two ropes via a prusik in order to rappel down once the swing was concluded. Another rope would be used to hoist the two dynamic ropes and rope for descending back to the jump site.
From what I recall in the video, they used every single bolt available and a lot of webbing. I think it was something like 16 individual anchors.
Finally you would need something that weighs about 160-200lbs to throw off the edge in order to test the length and stretch. I imagine you would want to throw it a couple dozen times at different weights just to make sure.
