Is it practical to precamber reinforced concrete slabs?
(OP)
I've heard some engineers say it's ok - you specify precamber into the formwork and then maintain constant slab thickness.
I've heard other engineers say forget it, it's impractical and you don't have enough control.
I tend to agree with the latter. What do you think?
For those who specify it, how do you make sure it happens?

It has no effect on the amount of movement which is what effects anything on top of the slab, such as masonry partitions or brittle finishes, glass curtain walls etc. Also has no effect on vibrations.
I would not think the objective is to maintain constant slab thickness, except possibly in a precast structure where the shoring is very widely spaced. In my experience it is used for deflection control.
