FIG Commission 6 - Engineering Surveys


"Surveying engineering deals with the production of data on the geometry and location, from large structures to small objects, either man-made or natural. In the domain of construction - the area that involves the majority of surveying engineers - it is present in the development of new buildings or facilities and during their life cycle: it’s vital for the planning, the setting out of the design, the dimensional control and the monitoring of deformations. The skills and the accuracy of the work presented, involved these professionals in projects assigned to other areas, ranging from mechanical and industrial engineering to environmental safety. "

FIG Working (from home) Week 2020 - Proceedings

May 2020

During the conference days a range of articles highlighting the hot-topics, the ground breaking research, and the hidden gems in the proceedings was published.

The diversity and quality of the communications gathered at FIG Working Week 2020 prove, once again, the event’s importance for the community of professionals. The six technical sessions of commission 6, are no exception and showcase the diversity of domains in which the professionals work, domains which generate many varied problems, yet which also present techniques that allow for an advance in quality, efficiency, and productivity.   Read the article

FIG publication 25: “Models and Terminology for the Analysis of Geodetic Monitoring Observations” is the result of the growing interest in the interdisciplinary approach to physical interpretation and modelling of the relationship between causative factors (loads) and deformation. It gives surveying engineers a solid basis for a unification of terms used in deformation modelling and helps to better understand the finesses of the modelling processes. 

Since its creation, Commission 6 has been involved in the organization, or supports the organization, of events for the presentation of the latest techniques and methodologies applied by surveying engineers. From these is important to highlight the FIG symposia on the overall theme of deformations monitoring, with almost 20 editions.
