Exclusive Video: Apple Campus 2 Spaceship ring rising with Lego-like interlocking slabs

Concrete void slabs are being trucked in to build an interlocking foundation and wall structure, which "serve as both the ceiling of one floor and support for the raised surface of the floor above," Apple has stated in its planning documents.

Also apparent in the latest video is a large underground area outside of the ring itself, which is now filled in with what appears to be two underground levels, likely to provide additional parking, mechanical and other uses.

The rapid progress on the Ring structure is evident when comparing the status of the project back in March (below), as viewed from the south.

Void slab construction

Emphasizing the results of working with diverse, local suppliers, Apple details on its jobs website that the concrete void slabs for Campus 2 were sourced from the family-owned firm Clark Pacific. To build the slabs, Clark Pacific was said to have "developed a unique structural design to meet the demands of Apple Campus 2."

Apple also says that Clark Pacific "now has four plants dedicated to producing products directly related to the [Campus 2] project," and has hired new workers to rapidly expand its operations.

"The innovation and manufacturing that went into Apple Campus 2 have also enabled Clark Pacific to expand to other large-scale construction projects up and down the West Coast," Apple stated.

Apple's web site states, "We have approached this [Campus 2 construction] project with the same care and attention to detail we devote to designing any Apple product. We will replace 2.65 million square feet of environmentally and operationally obsolete buildings with a 2.8-million-square-foot iconic, 21st-century research and development campus."

Expected occupation by the end of next year

Granted final approval just short of two years ago, Apple's Campus 2 project is rapidly moving toward its occupancy goal of 2016.

Apple's cofounder Steve Jobs unveiled the huge project in 2011, noting that the central 2.8-million-square-foot "Spaceship" structure would house at least 12,000 employees, surrounded by bucolic landscaping including orchards of fruit trees and other greenery, featuring open space and walking paths to reclaim most of the 150-acre plot previously covered by asphalt parking lots.

Phase 2 of Apple's Campus 2 project is also underway, which involves the removal of a series of older buildings along Tantau Avenue, the eastern edge of the initial Campus 2 project. Phase 2 buildings will reflect the minimalist style of the Ring, with large panes of glass offering engineers and other workers inspiring, unobstructed views of the surrounding landscape.

Note: Readers should be aware that Apple's Campus 2 site is extremely hazardous to photograph using an aerial drone, in part because the site is so large it is nearly impossible to fly over even one quarter of the site within constant visual or radio contact using consumer drone, and in part because the site is partially within an FAA restricted zone because of the nearby San Jose International Airport. There is constant low flying aircraft traffic over the site. We strongly encourage inexperienced aerial drone pilots not to attempt to fly in or around the site.
