Is this a problem ?
I once saw a large (900mm dia ?) aircon duct installed immediately in front of a switchboard's doors. Don't remember if it was a weekend job or a case of no 'local' staff visiting the job. Contractors organised by external consultants, perhaps they thought it was not being used anymore, well, it was !
Trouble is, consultants have no skin in the game, if something goes badly wrong, its another contract for them to fix it. And the guy who made the mistake, and hopefully learnt something, is elsewhere.
