eh, do we ever get a copy of CF?
is it during the last/final dispersement of loan?

CF - it is a condition for the 2nd final claim. So the architect will submit a copy to lawyer, and CC to you.
so we normally have it, and can request if it miss CC to us.

Achi drawing and electrical drawing - no, it is not part of SnP. From my experience with Sunway and IJM, > you can purchase it , as recall 200 Rm or so.
but is that of much use? normally not use for legal/buy sell proceeding. For renovation yes but contractor can do magic and been surviving all this while without any plan.
of course with plan will make their life much easier.
