Elevator pit slab lowering
Elevator pit slab lowering
(OP)
A contractor is facing a problem with elevator pit slab poured. The slab was poured 10" higher and now he need to remediate that problem. Also note that the pit wall is already poured & 3 story cmu elevator chase wall constructed on top of the wall.
What's the best to fix that problem without undermining the cmu chase wall?. He needs to cut the slab & have it poured at 10" lower.

May have to do this in a segmented underpinning mode to preserve the integrity of the CMU wall above, as in one side at a time so the wall can span over the voids created.

You then will have relatively free reign on what to do with the pit.
