Question ID: 602138
I am looking for information on how to size corporate space. Ideally,
the answers to this question will come from the airline industry
(Southwest, American, United, Continental, Frontier, etc, etc).
Barring that, any industry would do.

It is a two part question - part one focuses on employee specifics,
and part two on "common areas"

1. What kind of space (cubicle/office) does one typically assign
differing levels of an organization? Obviously, its hard to tie a
specific job title to another, so I've made it reasonably generic -
hopefully this will help. I am trying to determine appropriate cubicle
or office sizes for: General Managers, Managers, Supervisors and Admin

This question is more important than the second. 

- A General Manager should have _____ SQ FT (This would typically be
an individual responsible for all day to day operations across all
- A Manager should have ______ SQ FT  (This would typically be an
individual responsible for day to day operations of a specific group)
- A Supervisor should have ______ SQ FT
- An Admin Assistant should have ______ SQ FT

2. Common areas - How large should common areas such as: bathrooms,
locker rooms, conference rooms, break rooms (i.e. a lunch room).
Ideally, these numbers would be presented based on total employees -
that is "X SQ FT / employee". For example, if you have 100 employees
and the bathroom is 300 SQ FT, the "metric" would be 3 SQ FT /
employee - so that if you try and look at the size of a bathroom at
another office with 150 employees, you can extrapolate out and come up
with an estimated size for the bathroom.

Bathroom: ______ SQ FT / employee
Locker room: ______ SQ FT / employee
Break Room: ________ SQ FT / employee
Conference Room: ________ SQ FT / employee

***All answers must be sourced*** 

Ideally, I'm looking for answers by Dec 9th.
