REdsy:
Been there, done that. Harold's method works once or twice, unless it's areal dumb GC (doubt it)
Arseege's tactic works very well....as long as you can talk to the HO.
IMHO, unless you have a great relationship with a good GC, deal with the HO. Paperwork (contract; change order, etc) up to date, and you should be good.
