1. An excavator comprising:
a lower traveling body;
an upper turning body turnably mounted to the lower traveling body;
an actuator configured to change an orientation of the upper turning body; and
a control apparatus configured to perform front-face control to operate the actuator such that the upper turning body is caused to front-face a target surface, based on information regarding the target surface and information regarding the orientation of the upper turning body, wherein
the control apparatus performs the front-face control such that the upper turning body maintains a state of front-facing the target surface, while the lower traveling body moves along a direction in which the target surface extends.
