Ok, seriously now. This kind of work is done every day. A CG is not "our trade" otherwise he would know how to do this and wouldn't be dreaming about remote controlled cars and such. The fact that he or his company took on this contract with little knowledge of how to do the work, the codes involved and insufficient manpower speaks for itself.
This is what we have become accustomed to from CGs and it's one reason we complain about them all the time. Best advice I can give is to stick to what you do best and leave the rest to the professionals who know how to handle it.
