Build, construct (3,2)
I believe the answer is:
set up
This clue is a double definition.
'build' is the first definition.
(I know this)
'construct' is the second definition.

(Other definitions for set up that I've seen before include "Erect; fix" , "Contrived situation" , "Exalt - arrange - begin" , "a useful situation at tennis?" , "Assemble - design - establish" .)
