P&IDs Updation

We have been facing issued with updated P&IDs actually reflecting plant build. Should there be some regular checks /audits to see existing practices?

You would not find this weitten anywhere that you need to have such a check or an audit process in place but some sites have practice of regular inspection of their PSI package. I have seen some performing detailed line walk downs every 5 years.

OSHA 29 CFR 1910.119(d) clearly states that when a change affects process safety information, the documentation (including P&IDs) must be updated accordingly. And to assure this, you may have your internal procedures, workflow, and an audit process.

Yes, the reference has to be made to OSHA however CCPS refers to availability of process safety information as well.
Regarding the regular check, I would say that a risk based approach is best to follow.
I recall a guideline document established at our place to periodically verify PSI. However, that was focusing on high hazard areas at every 3-5 years, and utilities every 5-10 years.
This is in addition to having a robust system to update the documents with each change implemented at site.
