The Challenge
An environmental enclosure that was 185’ long x 100+’ high. Eight times during the project it had to be moved 185’ horizontal while at the same time raising the work decks almost 8’ vertical to match the rise of the bridge deck. On top of that, we needed to not add any additional load to the bridge structure itself.
