I'm going to expand from 3 hives to 6 next year and where the place I'm in now is barely enough room for the three I have.
Most of the time I like moving my bees after dark. If you already have a outyard you could move them there and make your splits at that location at the same time.
It depends on the equipment and the help I have:
