A construction apparatus (12) and method of controlling a construction apparatus from a laser source (38) made up of a substantially non-rotating beam (56). The construction apparatus includes a body (14), a construction tool (16) adapted to move material, a support moveably supporting the construction tool from the body and a control for guiding movement of the construction tool. A control is provided including a camera (28) that is adapted to capture an illuminated image that is derived from the laser source. The control determines direction information of the illuminated image with respect to the apparatus at least in part from an output of the camera. The control is further adapted to determine separation information of the spot with respect to the body and a physical relationship between the construction tool and the illuminated image. The construction tool (16) can be guided with respect to the illuminated image as a function of the direction and separation information and the physical relationship between the construction tool and the illuminated image.
