Heres what I'm thinking. Since we have money, we test test test to make sure things work. Then each developed nation usa, Russia, china, India, Japan, UAE, Canada, ESA etc with a space program launches 1 a day for a total of 30 days. That would allow 30 shipping containers to arrive within days of each other. The first few are redundant life support/escape/return, the next few allow you to start building, the last few allow you to grow. In the meantime we are building and launching as fast as we can. you have to think ahead by 9 months and have everything planned out as best as you can with redundancy. So scaling, teamwork, redundancy and thinking ahead. Also money, lots of money.
