Apple's new Campus 2, also known as the "Spaceship" campus, is an expensive and complex undertaking. When the project was first announced, Apple budgeted around $3 billion. On a project of this magnitude, cost overruns are to be expected, but maybe not as large as Apple's.
New estimates put the cost of the new Spaceship campus at around $5 billion. That's around 66 percent more than what was originally budgeted. Adding insult to injury, the projected move-in date has been pushed back from 2015 to 2016. But Apple can't cancel the project as it is a monument to the late Steve Jobs.
However, Apple is looking to save some cash. They want to reduce the cost by around $1 billion by reducing the fit and finish of the building. This means being less detail oriented and not building it to the same iPhone-level quality standards.
The question is should Apple be focusing its energy on building new products rather than a new campus? After all, stock price has suffered in the past year.
