With four months to go until the scheduled completion of Apple's second campus, work is progressing at a steady pace. Based on a new drone video posted this week, the main ring-shaped building at the center of the campus is nearly complete, as are many of the auxillary buildings.

Now that construction is getting to the end stages, workers at the campus have started the landscaping process. The giant pile of dirt that's been visible since the early stages of the campus is now dwindling down as its used for various landscaping projects.

Apple plans to add more than 7,000 trees to the campus, spread across 300 species, including many fruit trees. Steve Jobs envisioned replicating some of the California landscape that was around when he was a child, which includes sprawling orchards.

Along with 80 percent green space, the campus will feature employee amenities like easily traversable jogging and cycling trails and basketball and tennis courts.

Apple plans to have the campus completed by the end of 2016 and employees are set to begin moving in at the beginning of 2017.
