Beijing International Airport Daxing Grasshopper script

I am needing help with modeling the Beijing international airport. I am new to grasshopper and am needing help finding a place to being this project. I have found this project: Beijing international airport with grasshopper-parametric modeling in architecture - YouTube however I still don’t know where to begin. If someone has a script I could follow that would be very helpful.

You can just reach to the person who posted the video asking her if she can share her script.

People here are willing to help , unless someone already had a similar script. I don’t think many of us got the time to make one from scratch.
