Earthquake in Paris - Destruction of the Arch of Triumph

I repurposed a shot from Carlos G. Tinoco (https://instagram.com/carlito.nyc and youtube.com/watch?v=7m-Ql_zOB6E), around 2:30. 
The Arch was rebuilt using photogrammetry (RealityCapture) and Maya. It was then decomposed by cubic blocks in Houdini in order to get a more realistic destruction. 
RBD and Smoke simulations done in Houdini, rendered with Mantra. 
Surrounding buildings were built using NukeX and Maya. 
Camera was tracked in PFtrack. 
Trees were made in Speedtree and instanced in Houdini (packed disk primitives). Cars are very detailed models instanced in Houdini using point instancing. 
Cleaning of the plate was done in NukeX, as well as the compositing.
