Quality Control Assurance for Barrier Systems

Completion inspection. Once completed, each block of work is submitted to the completion inspection of the QCA personnel. QCA inspection personnel should first carry out a visual check of the completed facility component to ensure that it meets the design specification. The visual check can be integrated by tests in order to detect any defect, which could lead to the failure of the facility component. Selection of appropriate test methods should be based on site-specific conditions and on material types.

Test methods are based on generally acceptable practices for the technologies employed in similar products, such as compendia methods (e.g., ASTM, IEC, IEEE, NIST). Test methods include defined conditions for testing. The test equipment used for verification must be calibrated and controlled according to quality system requirements. Repeatability and reproducibility of test procedures are determined. Technical comments about any deviations or other events that occur during testing shall be documented.
3-D frame behaviour and load rating of truss bridges in railway infrastructure

It is worth noting that railway bridge testing has also been generally examined with regard to its uncertainty by Olaszek and Casas (2019). Both static and dynamic testing was covered in this work. Some of the critical errors were identified, such as those with the equipment, test method, model, environment, and analysis. Two examples of railway bridge testing were used to illustrate the importance of filter selection and quasi-static displacement identification in dynamic testing. On the other hand, few research efforts have been reported on load rating steel railway truss bridge using both load test and 3-D analysis, given that it is a very typical span type in railway infrastructure systems around the world. This is not to say that there have been few efforts on load testing truss railroad bridges. Actually, there have been many but not necessarily for code-specified load rating. They also have contributed to the body of relevant knowledge, for example, Caglayan, Ozakgul, and Tezer (2012), Moen, Shapiro, and Hart (2013), Ding, Zhao, and Li (2017), Tao, Wang, Hu, and Zhao (2018), Rakoczy, Otter, and Basye (2016), and Rakoczy and Otter (2018).
