Coping after deck pour?

[trophft]

Had some quality control issues with our batch of pre-cast concrete coping (major chipping and coming loose from bond beam), so they are ripping out and re-ordering. But in the meantime they want to pour the concrete decking, then come back and re-install the new coping. Is that an ill advised sequence that's going to cause issues?

It is easy to pour a deck and make it level with existing coping. It is not easy to install coping and get it level to a deck. It will be tough for the deck pour to know what level it should be.

The coping sets the elevation for the deck.

Why would you want the coping crew to work on top of your nice finished concrete deck if you don't have to?

PB agreed that there's only one right way. They've ripped up all coping, re-ordered all new coping, and pushed deck pour until coping is finished. They said they will make it right, so I'm feeling pretty good!

New coping installed today. Much better quality, still a few minor chips (I guess that's to be expected?), but only 3 or 4 spots versus 20 spots on the first batch.
