Latest aerial footage of Apple's Campus 2 shows start of work on 'spaceship's' garden & pond

Previous videos have shown the interior structure of the building, which is now shown as partially clad by the curved glass panels, measuring up to 46 feet wide, and 10.5 feet long.

Other work progression shown in the video includes near-completion of the parking structure with the buried facility in the process of being covered by dirt, the start of the security stand, and the beginning of the artificial pond creation in the open core of the headquarters.

The video also shows the start of work on satellite facilities to the main campus, such as research centers, and the maintenance structure. Additionally, more solar arrays are in the process of being installed, with a large number staged for the remainder of installation on the roof of the main headquarters, and elsewhere.

In 2011, Steve Jobs announced the project to the world, saying over 12,000 employees would work in the 2.8-million-square-foot "Spaceship" structure. Edible landscaping, walking paths, and other "green" improvements are in the process of construction, to minimize the impact the facility makes on the environment.

Apple's related Phase 2 adjacent project adds additional workspace, and includes a renewable energy-powered small data center.

Apple's microgrid is reportedly capable of handling about 75 percent of Campus 2 power requirements during work hours, supplemented by Bloom Energy-provided fuel cells. Bloom Energy provided similar cells, currently in use at Apple's North Carolina data center.

Campus 2 is expected to be completed by the end of 2016.
