I watched it a number of times and I am far from sure but there seems to be a couple of questions in my mind:
1. All the exposed rebar is clean---I did not see any that had pieces of concrete attached---that makes me question the concrete.
2. The erection technique they were using is mostly passe. That can put undue stress on members during the erection process---but there is no way we can tell that.
3. Cable-stayed bridges are a balancing act during construction. Clearly this thing lost its balance.
