Guys, here's my situation.

Draftsman has already sent me the drawings, signed and got the commissioner to chop and all.

Recently got a call from an engineer who says that needs his approval as well. I find that strange cos we didn't do anything for 1st floor. All works was for G floor only (extend front and back by 5ft each)

Is the engineer approval legit?

OK this one was cos of a mis-communication between me and the draftsman. All good now
