Concrete Slab - Integrity Reinforcement Cut
Concrete Slab - Integrity Reinforcement Cut
(OP)
On a two-way concrete slab (w/ drops at columns) contractor forgot to add some piping sleeves near a column and has decided it would be okay to core without scanning for rebar.
I looked in the hole and they cut 1 of the 3 bottom integrity bars.
Anyone have recommended repair details?

The fix approaches are numerous.....you might try to chip back the concrete and try a splice. Or (as I alluded to before) possibly slip some sub framing (steel perhaps) underneath the floor that would re-direct the load to elsewhere in the floor framing.

My first stop would be to recalculate the demand as tight as possible and compare that to the total number of bars going both directions. One bar in, say, six isn’t so bad. I’d probably let that go. Integrity reinforcing is hardly an exact science. Most reinforcement strategies would probably just weaken the connection anyhow.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
