For whatever reason this ceiling is no longer attached to its battens. The only thing holding it up is the cove around the edges.

We considered ripping it down and putting up new but after talking it over with client we decided it was worth trying to lift it up and screw it back to the battens. If it worked it would save about 50% of the cost of pulling it down and if it didn't it would add 25%. Fortunately it worked, so good call.
