Total Station Setup and Operation - University of South.
A theodolite or total station is set up over a control point which has known co-ordinates. The instrument is then pointed at another control point in order to orientate the instrument to north. If a conventional theodolite is being used it normal to turn the instrument to north and reset the horizontal angle to zero.

Total station consists of an electronic theodolite, an electronic distance measuring device (EDM) and a micro processor having a memory unit. By using this instrument it is possible to find out the coordinates of a reflector adjusting the cross hair of the instrument and at the same time measuring the vertical angles, horizontal angles, and slope distances.
A 'permit to work' is a formal, written, safe system of work to control potentially hazardous activities. The permit details the work to be done and the precautions to be taken (for instance, they may involve limiting the movement of overhead cranes, the precautions needed for high voltage work or they might detail rescue arrangements for certain types of work).
Another method, which furnishes a check when work is plotted is shown as in Fig (b) and consists of reading the bearing to any prominent point P from each of the consecutive stations. The check-in plotting consists in laying off the lines AP, BP, CP, etc and noting whether the lines pass through one point. Plotting a Traverse Survey.
Tacheometric surveying is a method of angular surveying in which the horizontal distance from the instrument to the staff stations are determined from instrumental observations only. Thus the chaining operations are eliminated. Field Work can be completed very rapidly Tacheometry is mainly used for preparing the contour plans of areas.
Setting-out procedures for the modern built environmentis an entirely revised and updated publication which includes modern instrumentation and techniques and describes recommendations for setting-out of building and civil engineering works. These are based on the practical experience of practising engineers and are applicable to most.
