I have researched the technology required for GBT. However, I cannot find GBT in build options. Then, I clicked on different builders, still I could not find GBT. I am in an online base on Win 10. Version V0.63.0.
You can find all requirements here:

Builder is the Megabot.
It also will not show up if you do not have all of the required resources. One requirement is Wood, which you may not have yet at lower atmosphere levels.
