I am putting back together a ceiling where the sheetrock was cut away due to burst pipes and all the ensuing mess. The people who saved the day by arriving a few hours after the mishap and dried everything nicely, cut two 16″ wide strips (18′ long). These two strips are separated by approximately 4′ of sheetrock. This is in a garage with living space above, so it is doubled up 5/8″ rock for the firebreak. My question is how concerned do I need to be with offsetting seams? The joists are perpendicular to the cuts so can I get away with filling the gaps with 16″ doubled up rock, tape and mud and call it a day? Or do I need to pull the rest of the rock down, start from scratch, offset the seams, etc?

How about this
If you arre concerned with the seams could you just widen the strips in the first layer of rock enough so you could tape the upper layer.
After that is done patch your now 20" inch strip mud and tape VOILA!
Are both layers taped or just the exposed layer, that should answer your concerns as well.

I like it!
It is just the exposed layer that is taped. I guess my concern was more about the firestop and having both layers lined up. It is an insurance job, and I didn't want to step into something that looks straight forward and turns out to be something more than just filling the hole.
Insurance job? I'd touch base w/ the local BO and see what he has to say. You may need to get a permit anyway and since it is insurance work, better to have the loose ends addressed than not ... plus you will be that much smarter!!
Common sense suggests that you would cut the outer opening several inches wider than the inner one, so that there is some overlap of the rock.
