Notes

(1)This subclass covers underground structures made by foundation engineering, i.e. involving disturbance of the ground surface.  [6]

(2)This subclass does not cover underground spaces, made by underground mining methods only, i.e. not involving disturbance of the ground surface, which are covered by subclass E21D.  [6]
