Apple's Campus 2 construction is still well underway, and a new flyover video from drone pilot Duncan Sinfield shows that the exterior walls are starting to come together nicely. In Sinfield's February update video, we can see that workers are beginning to lift pieces of the roof into place, while glass panels continue to be installed around the exterior.

Sinfield's video also peruses other portions of the the under-construction campus, including the roof of the underground auditorium. We can also see that the solar panels on the western parking garage are also fully in place.

In all, the video is a fascinating look at Apple's progress, and it's much easier to see just how massive Campus 2 is in this latest flyover. The project is expected to be completed in early 2017, at which point it will house around 13,000 employees.
