Since last checking in a month ago, today Duncan Sinfield gives us an update on progress at Apple’s under construction Campus 2 in his latest drone flyover video of the site.

In the video, we see Apple’s progress in recent weeks including the continuation of the installation of the giant glass panels — the largest in the world — on the main building, as well as preparations for installing the nearly 700,000 sq. ft. of rooftop solar panels that will be on the site when complete.

We also see some progress made on the structures surrounding the main circular building, including the 100,000 sq. ft fitness center, the exterior of the underground auditorium entrance, the separate R&D facility, and the two parking garage facilities that will hold around 10,980 parking spaces.

Check out the full flyover video below:

Apple is still expected to complete construction on the site by the end of the year, but it recently extended its schedule for street utilities, originally thought to be completed at the end of 2014, through 2016 in its general project schedule on the City of Cupertino’s website (below).

If Apple finishes on schedule, it could start moving in the roughly 13,000 employees the new 2.8 million sq ft headquarters will hold by early 2017. And indeed Cook said at a recent shareholders meeting that the campus should be ready within the expected timeframe.
