One would expect an engineering firm to be able to set up doc conversion for the special people who need "proper documentation" and consider Word to be at all related to that. Every "document" I've ever gotten from an engineer has been a PDF, which should work even for special people.
in over 20 years crossing around 10 different companies, all documentation produced has been in Word format... never a single exception other than simple text files for extremely minor stuff.
Word rules the world... love it or hate it, its the truth.
