Dive Brief:

• A construction insider who has been involved with the building of Apple's $5 billion new campus in Cupertino, CA, said this week the computer giant "has raised the bar for construction standards," according to an exclusive interview published in Business Insider.

• Every detail of the building, dubbed "the spaceship" because of its circular shape, "has been looked at and vetted and measured and mocked up, from concrete to joints to rebar placements," the contractor said. "Stuff you wouldn't even see when the building's done, so it's pretty amazing."

• Apple supervisors routinely referred to the iPhone when explaining the level of attention to detail expected during construction. Holding the phone,one rep said: "That’s what we're building," the source reported. "What that means is: If you look at the phone, there's the sheen on the phone, there's the bevel on the phone, there's how much shine they have. … Every piece of that phone is engineered, and the building is the same way."

Dive Insight:

The contractor told Business Insider that subcontractors and trades involved with the project often wondered how any future buildings could top this one when it comes to Apples' exacting standards.

"If Apple now has raised the bar for construction standards," he asked, "what's the next project? Is it going to be higher than that? Is it going to be an Apple standard?"
