• participation on the FIG Standards Network on standardisation policy, support the standardisation activities at the international, local and national level, and development of standards and method statements
• participation on regional FIG events, and events organised in co-operation with sister organisations.

General

This Working Plan covers a wide scale of survey disciplines related to plants, installations and constructions of any kind. Commission 6 wants to promote:

• development of international standards and qualifications,
• development of best practice guides in Engineering Surveys,

Commission 6 will consist of three Working Groups and one joint working group with Commission 5. Commission 6 has study groups on specific issues and these could also be used for the FIG contribution to respond to global warming and disaster management.

The Council has requested Commission 6 to consider establishing a Memorandum of Understanding with the Institution of Civil Engineers (ICE).

Working Group 6.1 - Deformation Measurements and Analysis

Policy Issues

Deformation studies in Engineering Surveying are based on a broad knowledge of suitable sensors and their potential, modern data storage and communication solutions and advanced processing and analysis methods. Additionally a thorough understanding of the behaviour of monitoring objects (large scale structure or landslide effected area), is essential to set-up and operate an optimum monitoring system. Nowadays deformation tasks are more and more oriented towards real-time systems, which require automation of data capture and new concepts in data processing, analysis and interpretation.

WG6.1’s main goals will be to support specialists in deformation studies with state-of-the art solutions and provide latest developments and future oriented concepts:

• Promoting studies on the potential of existing and new sensors to determine geometric deformation quantities from surveying and adjacent fields such as geotechnics;
• Promoting the development of concepts for automated data storage, data transfer and data pre-processing;
• Promoting the adaptation of numerical algorithms to derive relevant deformation quantities in real-time, including concepts from time series analysis;
• Promoting a multidisciplinary collaboration between surveying, structural and geotechnical engineers to understand the behaviour of structures and geotechnical objects;
• Study of most modern concepts for data analysis like artificial neural networks, fuzzy logics and generic algorithms;
• Initiate investigations to extend the range of deformation studies to higher frequencies, which are important in Structural Health Monitoring, i.e. to be able to study oscillations and vibrations and their effects on critical structures;

Chair

Specific project(s)

• Prepare reports on State-of-the-Art for typical deformation tasks (e.g. dams, bridges, high buildings, landslides, rock-fall, …);
• Comparison of most modern instrumentation for automated deformation measurements;
• Comparison of concepts from artificial intelligence for deformation analysis;
• Case studies: For a typical data set of continuous observations, which has to be defined, different analysis concepts and tools have to be applied.

Workshop(s)

• 14th International Symposium on Deformation Measurements, Hong Kong, Nov. 2011
• 15th International Symposium on Deformation Measurements, Europe (Hamburg ?), 2014

These symposia will continuously be organised as joint symposia with IAG/ WG 4.2, Publication(s)

• Study the use of embedded sensor arrays and the role of advanced surveying techniques for structural monitoring;
• Creating an awareness of surveyors through a task force “Fibre optic sensors” of the rapidly emerging technology of fibre optic sensors as "non-geodetic" sensors to measure deformations (strain) and temperatures in civil engineering structures
• Promoting the use of Terrestrial based RF positioning system in engineering surveying;
• Creating an awareness of surveyors through a task force “Geotechnical sensors” as the trend today is going for an integration of those sensors in the geodetic deformation analysis.
