It's been a while since we checked in on the construction of Apple's second campus in Cupertino, California. Aerial GoPro video depicted construction in its earliest stages back in late August of 2014. Roughly a year later, a new video uploaded by drone pilot Duncan Sinfield depicts the sprawling campus taking shape. You can now see the completed foundation of the massive 2.8 million square foot ring-shaped main building, as well as conspicuous progress on the parking structures and auditorium. Check out the video below.
