A construction equipment includes a work machine which includes a boom, an arm, and a bucket operated by their respective hydraulic cylinder. The construction equipment also includes a control valve for controlling the hydraulic cylinder; an operation lever for outputting an operation signal corresponding to an operation amount of a driver; a work setting unit for setting a work area; a location information providing unit; and an electronic control unit. The electronic control unit is for outputting a control signal for the control valve according to the signal inputted from at least one of the operation lever, the work setting unit, and the location information providing unit. The electronic control unit calculates an angle between the work area and the work machine, and controls a speed of the work machine based on the calculated angle.
