Make progress by relocation of part of hospital? (4,7)

'make progress' is the definition.
'move forward' can be an answer for 'progress' (thesaurus). I am not certain of the 'make' bit.

'relocation of part of hospital?' is the wordplay.
I cannot really see how this works, but
'relocation' could be 'move' (I've seen this in another clue) and 'move' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
'part' could be 'ward' (I have seen 'Part of hospital ' mean 'ward' so perhaps 'part' could also mean 'ward') and 'ward' is found within the answer.
This explanation may well be incorrect...

'by' is the link.
