I am sure when they architected this building, they did not set out to melt cars with the power of the sun. But, that is exactly what they did. The unique design of the building is producing enough heat in a concentrated area to burn carpets and melt parts of cars bodywork. The architect has stated that he knew this could happen but he did not have the tools to properly model, predict and prevent the effect. As a result, the ultimate bandaid solution has been applied (scaffolding to block the deathray) while design changes are implemented.
No one wants to compromise a design, but having to apply workarounds and to make design changes in the field are much worse. Ultimately, preventing design failures is the goal of every engineer.
This is not an isolated incident and this articles gives a nice history of other buildings that melt things!
