What is the process of surveying

Engineering and industrial surveying

Engineering surveying

The main fields of activity of engineering surveying are in construction as well as in mechanical and plant engineering. The control and quality assurance of complex construction and manufacturing processes requires the provision of high-precision geometric information about the current status of the components involved in the process. Practical examples for participation in construction processes are e.g. the control of driving machines in tunnel construction, the monitoring of the stability of buildings and geotechnical objects as well as the precision marking out of bridge structures and high-speed roads. In the area of ​​industrial production, quality control in the automotive and aircraft industries is particularly important. By using the most modern measuring systems (including robot total stations, laser scanners and laser trackers), the engineering survey records and evaluates the relevant information in real time. It accompanies the entire process from planning through technical implementation to further monitoring to avoid damage. Engineering geodesists are therefore all-round talents who develop tailor-made solutions for the efficient processing of metrological problems in a highly dynamic environment.

The fields of activity of engineering geodesists are very diverse. The area of ​​construction includes the generation of as-built plans as a planning basis for building projects, the creation of highly precise engineering networks as a basis for the implementation of buildings, the entire construction-accompanying survey (building staking out and mapping) and building monitoring to avoid building damage or to clarify the causes of damage. The latter task in particular goes far beyond surveying and requires detailed deformation analyzes and interpretations, which are carried out in close cooperation with civil engineers, geotechnicians, geologists and geophysicists. Here, engineering geodesy is heavily involved in the development of early warning systems. The area of ​​industrial surveying includes the development, calibration and application of mechanical, electrical and electro-optical measuring systems, which are able to carry out measurements at high frequencies (sometimes several thousand measurements per second), extremely precisely (sometimes in the μm range) and as automated as possible. The measuring systems are integrated into existing industrial production processes and provide the basis for quality control of the products produced (e.g. shape control of vehicle components). Industrial surveying is also involved in the planning, precision staking out and monitoring of technical systems. This includes production facilities of all kinds, but also power plants (e.g. wind and hydropower plants) and research facilities such as particle accelerators.

Engineering surveying is therefore a strongly interdisciplinary scientific discipline. Engineering geodesists work closely with civil engineers, geologists and geotechnical engineers, geophysicists, mechanical engineers and electrical engineers. In addition to geodetic knowledge, this cooperation also requires well-founded, interdisciplinary knowledge in the above-mentioned areas and great social skills. Engineering geodesists are not only able to measure, but also to intervene in complex construction and manufacturing processes.
