Abstract
The location of one of a series of construction points at an indoor construction site is established using a robotic total station and a handheld device. Construction data is inputted into the handheld device with the construction data defining a plurality of construction points at the construction site. One of the plurality of construction points is selected with the handheld device. Data regarding the selected construction point is then transmitted wirelessly from the handheld device to a robotic total station. The robotic total station generates a beam of laser light, and directs the beam of laser light from the robotic total station to the construction point. The construction point is defined by x and y coordinates, and by an assumed z coordinate. The actual z coordinate is that of a point on a horizontal surface, such as a ceiling or floor, having the same x and y coordinates. Through an iterative process, the location of the construction point is established.
