Matrisk developed a software that allows risk analyzes for tunnel systems to be carried out in accordance with FEDRO guidelines 19004 89005. This software was used to perform the example calculations published in the supplement (FEDRO 89007) to the FEDRO guideline and can therefore be regarded as a validated standard. The software enables Matrisk to carry out calculations quickly and cost-effectively, allowing many scenarios to be analyzed and evaluated in a short time. Due to the large number of practical projects as a result of the development and the methodology, Matrisk has special and almost unique expertise in this area. With this software, tunnel risk analyzes can be carried out both in Switzerland and internationally.
