This paper presents on-site applications of two innovative monitoring tools, based on 3D MEMS sensors and specifically designed and intended to be installed in underground excavations. The first one (Cir Array) is designed for near-real time monitoring of convergence phenomena and localized deformations taking place in a specific tunnel section. The second one is called Rad Array and it is designed to be installed in radial directions with respect to the tunnel section, in order to identify deformations some meters inside the rock mass surrounding the underground excavation. The satisfactory results obtained from sites highlighted the importance of a well-designed and efficient monitoring system in tunnelling operations. The monitoring sys-tem allowed to investigate the accuracy and precision of the measure on site, collecting useful data regarding the structure conditions for both cases presented in this study.
