You may couched your delight at someone tragedy with polite word but that is beside the point
The truth is building or bridge failure happen all the time. Let me remind you of last year Minnesota bridge failure
Learning from bridge failure
Collapses such as the I-35W in Minneapolis give engineers the best clues about what not to do. Let's hope the lessons are remembered.

The collapse of an interstate highway bridge over the Mississippi River in Minneapolis took everyone, including engineers, by surprise.
We do not expect our bridges to drop out from beneath us, and their designers take great pains to ensure that they do not. Among the surest ways to obviate the failure of any structure is to anticipate all the different ways in which it can fail. Thus, in designing the Minneapolis bridge, engineers had to consider the consequence of a single steel member breaking, buckling or otherwise failing to carry its intended load.

Airport Roof Failure Blamed on Process
Report on fatal collapse of novel concourse at Paris airport charges systemic flaws in design 2/21/2005
By Peter Reina in Paris
In what amounts to a harsh indictment of the French process for executing complex public projects, investigators have identified two likely reasons for the partial roof collapse at the 650-meter-long concourse at Paris Charles de Gaulle airport last May 23. Systemic flaws in designing the technically difficult building contributed to deficiencies that led to the early morning failure that caused four deaths.
The government-appointed team identified two key failure mechanisms but cannot say which was the primary trigger. The design process was insufficiently rigorous for so complex a structure, investigators said at a press conference on Feb. 15. No detailed, independent analysis was done to check design models
