Fitting UPVC Doors before or after screed?

Hi, sorry in advance if my terminology is incorrect, We are having an old side building revamped and floor is being raised slightly. We need to order new UPVC doors. A concrete sub-base has been laid to raise the floor and I'm told a layer of around 3 inch screed will do the finer adjustment. What I would like to know is do we fit the doors first and make some sort of allowance for the amount of screed to be laid or do we need to measure the doors to sit on top of the screed layer as such? (As therefore better to wait until screed is laid?)
