Timeline

Land clearing begins for the entire site.

2025-07-01

Building 1 is operational. This is based on the state of construction on 2025-03-02 as seen on [Google Earth](https://earth.google.com/web/@33.35450568,-111.67805903,407.02398359a,2119.1496037d,35y,-0h,0t,0r/data=ChYqEAgBEgoyMDI1LTAzLTAyGAFCAggBQgIIAEoNCP___________wEQAA), where building shell and external components seems to have been completed, but there is still a lot of construction equipment present. That equipment appears to have been cleared up by this date, 4 months later, with the 2025-09-07 satellite imagery providing an upper bound. Construction has begun on the Building 2 roof, with work beginning on the areas for cooling and generators as well.
