Significant progress is seen each time we see new video updates.
Another update from the Tesla Gigafactory 3 construction zone comes in. After we just watched a video of the skeleton of the roof, now it seems it's mostly done.
Chao Zhou, who shared the recording on May 3, 2019, wrote that the first main building will be completed by the end of May.
"27 days due to complete, it's solid progress by the plan. Tesla will finish the building by May and begin the production before September"
