ICF form/wall question

[JStructsteel]

When detailing ICF forms and slabs. Do you have them remove the insulation to pour a slab up against it? I have some locations the slab is bracing the wall, so that seems like a no brainer. At other locations, any issue just pouring up to the form insulation?

We have detailed leaving the foam a number of times. Some complain about the work, others have told me it is a minor task. The EPS foam used is between 10-15psi. At the rated load it will only compress 0.26" if your insulation is the typical 2 5/8" thick.

Is there a creep component to that deflection?
