The growth of many of today’s megacities has been unplanned, spontaneous and uncoordinated. The aim is to improve the living conditions and quality of life. Mechanized tunnelling technology can assist with the rapid implementation of major projects to develop the infrastructure necessary to achieve these improvements. The Grand Paris Express currently ongoing in Paris is an example of a large-scale infrastructure project that illustrates the benefits with a focus on tunnel construction using the TBM technology with hydraulic muck transport. The paper highlights tunnelling sections where the innovative Variable Density TBM technology is used. The focus is not only on its advance strategy in respect of flexible adaptation of operation principle but mainly on the benefits for the overall workflow at the working shaft where less installation area is required with hydraulic material conveying than using EPB shields with dry mucking out via tunnel belt or even muck skips.
