After pushing / pushed the factory, the goods will be ready for inspection on 22 April.
I imagine emsr2d2's problem in guessing what 'pushing the factory' may have arisen from the fact that the participle's dangling. It can be silly to ban all dangling participles everywhere (though it's a safe poilcy ito avoid them in an exam!) - but there are times when they hinder communication; and I think this is one.
