old 150mm foundation in sub base

Hi
Just poured the foundation for a new extension. Inside the foundation perimeter are some old strip footings for an outbuilding. These sit just below the level i am bringing my sub base/ hardcore level up to! About 20mm below. Should i remove them or just cover them over with hardcore??
cheers
