Interior piers in two pours?

[davidj]

My official plans call for a few piers, both inside the house to support a girder down the middle and outside the house to support the decks.  Each piers is typically a 24" x 24" footing with a 12" sonotube-formed vertical cylinder with an embedded metal post base.  I'll be putting in some horizontal rebar in the footing and vertical from the footing up through the sonotube-formed section.

So my question is - can I do these in two pours?  I'd like to do the pier footings when the concrete truck is here pouring the footings for the (block) foundation walls.  However, the vertical pier and post base would be much easier to do accurately when I've got the foundation walls built and I've got the girders, joists etc. on site (maybe 9 months later, as Winter is 5 months of downtime).  Given the number and size, I could easily mix the concrete by hand for the vertical piers.  Do I need to do anything more than just leave a few bits of rebar sticking out of the footing (with little OSHA orange caps, of course)?

Yes, you can do these in two pours - the stub of  rebar left sticking up from the footings will tie the two together when you wrap that with the bar(s) in the pier.
