Henderson Chemicals(has been building) a new refinery (in Simcoe County) now for me the first one is a Verb Phrase, but am not sure of the second one?

Sheila (has been revising) the procedures manual since she returned (from vacation) The first for me being a Verb Phrase the second I do not know ?

Thelma said (to send duplicates) (to Ms Jay and Mr. Wu). the first I belive to be an Infinitive Phrase again the second I am not sure?

Henry(has been) busy (on the Erickson account). I belive the first is a verb phrase and second is a Prepositional but am not 100% sure?

The inventory report (will have been completed) by the time we go (to Vancouver) I think this is a verb phrase and a prepositional phrase but again am not sure..

I hope you can clear this up for me and explain what makes it what..
thank you so much
