Not even they necessarily have the experience to do it! Intel has a policy called "Copy EXACTLY!" for fab construction where they make every irrelevant detail the same as their last fab, because they don't actually know which of the details matter.
After spending a lot of time studying the problem what they finally realized is they built the building too close to the interstate and vibrations from the interstate were ultimately making their way into the factory causing errors.
To combat this problem, they spent millions retrofitting shock absorbers onto the building.
It's not shocking that intel would do the same because even the slightest movements and vibrations can spoil the chips. Putting a restroom in the wrong spot might spoil a batch when someone flushes the toilet.
