This one says 27 years, and gangs of 100k labourers. 2.3 million blocks, totalling 6 million tonnes. 5.5 million tonnes of limestone, 8k tonnes of granite, and 500k tonnes of mortar.
By this, density of some local limestone is between 2250kg/m and 2700kg/m, a tonnes is 1000kg. This is a difficult size to manage, but with log rollers, and 100k workers, 27 years is absolutely doable.
I’ll agree on the why. But the how isn’t really a mystery.
Placing about one block every 3 minutes is easy to explain?
From the article you linked.
None of the things you linked say anything about the time frame for construction.
