How are you able to build it so fast?

We are able to construct so rapidly because of 3 reasons.
The first is we don't use concrete so we don't have to wait for it to cure. That saves a lot of time because it takes a month on average for concrete to cure.
The second reason is our construction technology is like a giant lego made out of prefabricated parts. Building a lego is much cleaner and more efficient process than building a “sand castle”.
And finally the third reason is geodesic domes can be very simple. Simple in a sense of how just a few parts are needed. Though the process of designing such simplicity is anything but simple.
