The meticulously-planned ‘war effort’ to reconstruct Notre Dame

The meticulously-planned ‘war effort’ to reconstruct Notre Dame: A massive initiative to reconstruct the Notre Dame cathedral is underway, following the fire that decimated parts of it — and even with the use of cutting edge technology, it’s expected to take at least five years, this FT video shows (watch, runtime: 06:49). For the reconstruction process to begin in earnest, experts in 3D scanning are using laser scanners to create an exact digital copy of the cathedral, from which they can then create a 3D model. The whole process needs to be undertaken with meticulous care. Notre Dame’s characteristic arches are very thin, and their balance is extremely precise, meaning the whole building is at risk of disappearing forever into the annals of history if the structure is not solid enough.
