Thanks Michael for your opinion. Your definitely right, vendor will always ask for extra payment in cases these things slip through from FEED to EPC without noticing this type of requirements. It's sometime disappointing to see this kind of requirement in bid and quote.


Anyway, just sharing my experience. I have seen this twice already from two different EPC company. They will just say engineering judgment will come into play.

Any other opinion is highly appreciated.

Cheers!!
