With the precedent for coups in Turkey I don’t think there’s that much planning involved for the strengthening of control afterwards. Erdogan purged the army ruthlessly and declared a state of emergency, pretty par for the course after an attempted coup.

He definitely widened the net of his purge and take out some political enemies, but I don’t think Erdogan reacting fairly predictably to an attempted coup is proof that he knew of it before hand, or planned it.
