Core Drills

What would happen of you cut one of the cables in a post tensioned floor in a building?

I am an electrician by trade and I do a lot of core drilling to penetrate floors between levels in a building. Someone suggested to me that I should always check with the building engineer before I drill to be sure it is not a post tensioned floor I am drilling through. They explained that if I cut a cable in the post tensioned floor, the cable could come flying out of the side of the building... any truth to this???

practically nothing , i mean the floor won't collapse , what will happen is that the Bending moment will increase & a deflection occures , it won't collapse just because we take a large factor of safety almost 2 times when we design such slabs.

about the cable coming flying , actually i don't know i wasn't told so , besides i didn't have a training with a post tensioned beams or slabs.
but in order to make such a cable tensioned it'l pulled by a hydraulic jack & then wedged so that it won't loose it's tension.

so it's under tension & when u cut through it when it's like that , i just don't know .... it may fly as they told u , but frankly i don't think it will .......that doesn't mean u can cut it anyway.
