7 The work is organised according the proposal, in particular this contribution is related to work package 4 - Certification . The objectives of this task in the proposal stage have been: To create a Certification agency to help overcoming duplication and costly parallel development. To enable calibration of methodologies and hardware components. To fulfil the targets of Certification as proposed, the following work should be conducted. This report should serve as draft for implementation of the following tasks: Setting up a Procedure for Certification To carry out Certification benchmarks To contribute to the codes and recommendation of WP 3 Consequently this report is starting point for developing a Certification Procedure in the post SAMCO time. The main focus should be on Certification of the hardware as well as the methodology, because both are an important factor of successful structural assessment and in particular structural health monitoring.

8 Using vibration analysis to monitor, which means detect and localize damages in civil engineering structures has become yet a key maintenance activity for some structures or structural components. In mechanical engineering, these techniques are representing the current state of the art since several years. There is no machine, car or aircraft developed without excessive analysis of the dynamic structural response. In this field, usually well known and recognised technology is used, due to the fact, that the tasks and the objects under investigations are much more simpler compared to civil engineering structures. Mainly identification of natural frequencies is sometimes sufficient only, to compare a large number of serial products or to maintain the quality of mechanical components which is represented by the modal parameters.

9 Certification of methodology and hardware components is not from importance, because ready to use solutions are implemented. The individuals who are performing these tests however, are following a strong trend to training and Certification in order to improve their knowledge and quality of work. The civil engineering situation is different. The structures are usually prototypes, with very inhomogeneous material composition. The sizes are much bigger and testing therefore is much more effort compared to mechanical engineering. From this point of view, structural assessment and in particular health monitoring is a complex Procedure . Black-box systems which can be installed on structures are not existing currently, due to the different nature of the given problems and structures.

10 If a monitoring program is required, it must be adapted to the specific structure and the problems to be solved. Thus, quality control and Certification during all steps of measurement, data evaluation and data interpretation are from major importance. The effectiveness of monitoring programs in civil engineering strongly depends on three factors which are: the capabilities of the individuals who acquire vibration measurements, interpret the data and manage the programs. the hardware which is used for the different tasks. the implemented software solution, the evaluation method, which is base for determination of the modal parameters. The results are starting point for interpretation of the health condition of the investigated structure.
