Condition Assessment and Inspection
The main objectives of WP3 are to provide:
improved condition assessment and inspection systems,
new or optimized methods for inspection, primarily NDT,
including all materials as concrete, steel and masonry.
The results will be demonstrated in WP7 and 8 and training to delegates from the railways will be provided Oct. 2006 in WP9.
The first phase of the project was focused on getting information on the state of the art, making a proposal for a new condition assessment system (which can be used in hole or party by interested railways, but is also aimed to demonstrate the integration of other project findings) and to develop and optimize NDT tools.
Currently the results achieved so far are collected in a NDT toolbox and will be integrated into the new condition assessment system.co-ordination, definition of tasks and specifications
Damage Classification/Condition Assessment/Inspection
One of the most important outcomes of WP3 will be:
unified nomenclature and classification of damages
integration of new tools into inspection guidelines
giudance on the use of NDT (and other) tools for condition assessment
An innovative proposal for a new condition assessment system demonstrates the use of 2D modeling and expert systems.
Information on (if possible) on all available NDT methods, including fields of application and limitations, is collected on one page datasheets. This information can (and will be) linked to damage catalogues or condition assessment systems to provide the necessary information to the bridge engineers.
Sample NDT Toolbox data sheet and planned usage in NDT Toolbox
A lot of NDT methods have been developed, tested and optimized in the first two years of the project. Below you will find a fine selection:
2D scanning systems for multi sensor investigation of bridges (BAM)
Ultrasonic C-Scan: tendon ducts in 9 to 29 cm depth (BAM)
Masonry bridge investigations in Poland (PKP/WUT/BAM)
Radar tomography at Portuguese concrete bridge: two concrete qualities in one pillar! (UMINHO/BAM)
