Land Surveyor

plumbing down from a height point

Plumbing down from a height point, plumbing up from a ground point, and inspecting a vertical line on a structure, can be carried out exactly in just one tele- scope face, but only if the telescope describes a pre- cisely-vertical plane when it is tilted. To ascertain that this is so, proceed as follows: 1. Target a high point A, then tilt the telescope downwards and mark the ground point B. 2. Transit the telescope, and repeat the procedure in the second face. Mark the point C. The mid-point between the points B and C is the exact plumbing point. The reason why these two points do not coincide can be a tilting-axis error and/or an inclined vertical axis. For work of this type, make sure that the total station has been levelled up pre- cisely, so that the influence of vertical-axis tilt on steep sights is minimized.
