Floor boxes - don't get me started
Oh yes, floor boxes, the most moronic architectural fad since Le Corbusier decided ugly was beautiful and concrete chairs were comfortable. But a lot more dangerous.
They're supposed to be "flexible". That means, you might be able to have them moved, if you have a large stock of spare matching carpet tiles, can afford to employ a carpet fitter, and an electrician, and a network technician. You may also need to replace the entire cat-5e or fiber run, if the original installer didn't think to leave a couple of meters of spare length under the floor in case the box needed moving a few feet.
In practice the furniture gets moved, the boxes don't, and cables are left trailing across the floor under people's feet and wheely-chair wheels. When cat-5e fly-leads get crushed, data unreliability results. Worse, when mains cables get crushed, a fire or shock hazard results. I have seen more than one instance where the insulation was melting because the underlying copper was fractured, and others where live copper was exposed. And of course there's the trip hazard. Get a cable caught around your ankle, and if you are lucky you get a sprain that develops into arthritis during your retirement and puts you in a wheelchair in your 80s. If you are unlucky you trip, bang your head on the corner of someone's desk, and are dead or a vegetable an hour later.
And when the much maligned Health and safety people spot the hazard and insist that the floor box is moved, the architect-types then tell you that it's impossible to get the box within two feet of this or that wall or pillar, so you discover that several square meters of expensive office space are effectvely unusable.
All of which happens after the architect has won some sort of award for a beautiful expanse of carpet tiles and unused desks uncluttered by visible sockets, and has moved on to fuck up someone else's workplace.
