CIP Conc piles are normally cast to the required 'cut-off' elevation. Precast and steel can be cut off at time of installation, except they can be checked prior to cut off if there are adjacent piles to be driven.

Except for micropiles and odd installations, it is not common to do an integrity test in these locales.

Pile caps can be installed within a couple of days of pile installation.

I usually have the contractor loosen the forms after a day and allow removal after 3 days.

Pile cap loading can occur within a week. Care to make sure anchor rods are not damaged by early loading.

Full design load should be after 28 days... longer time the better for long term movements.
