S19: The Most Advanced Engineering Project in Poland

The S19 Rzeszów Południe–Babica contract is one of the most demanding infrastructure projects in Poland. It includes the excavation of two single-bore tunnel tubes, each 2.2 km long, with a diameter exceeding 15 meters, under challenging geological conditions of the Carpathian flysch formation and in the presence of methane. The project requires the use of state-of-the-art TBM technology as well as an innovative approach to safety, logistics, and geotechnical risk management.

The investment is being carried out by a consortium of Mostostal Warszawa S.A. and ACCIONA. The contract value exceeds PLN 2 billion.
