ABSTRACT

Elpa Project is a joint effort of Elpa and Rina Consulting S.p.A (appointed by NTA Ltd that is the responsible for the design and construction of a mass transit system for Tel Aviv) to establish a clear classification of the findings of Red Line Metro in Tel Aviv and clearly communicate them. The tunnel extends from Bat Yam to Petach Tikva in Tel Aviv and is one of the most heavily used traffic corridors in that Metropolitan area. 8 TBMs of internal diameter of 6,50 m will complete the underground Metro excavations adopting EPB methodologies in calcareous sandstone under sea water table in a very urbanized area. Elpa effort produced a novel approach to the analysis and the communication of findings and corrective actions to Contractor and Engineer during excavation monitoring. This method merges a strong expertise in TBM analysis with state of art tools for Big Data management.
