Philipe, hi!
I have a rule of thumb that 10,000 sq. ft. of substantially interactive
exhibition takes 3 people to maintain. 2 - 2.5 of these people have a tool
pack on their belts; the rest is overhead - management, accounting, design
and fabrication (for those exhibits that are unmaintainable and just must
be changed), graphics (for those graphics which just must be changed) etc.
Many people think that this is a high estimate - but I think that they
haven't added up all the bits. Most science centers are open 1.6 times a
person-year of 236 days, so quite a few of these maintenance people must be
part-timers.
Good luck!
Peter Anderson
