Mostostal Warszawa SA is one of the largest construction companies in Poland.

Artur Salachna, Contract Director for the S19 Rzeszów Południe–Babica project, has been appointed by the President of the Wyższy Urząd Górniczy (Higher Mining Office) to the Team for the Development of Best Practices in Tunnel Excavation. The Team’s task is to develop and define standards for the implementation of tunnel construction projects in Poland.

At the construction site of the S19 Rzeszów Południe–Babica expressway, one of the most advanced and demanding engineering operations currently underway in Poland is in progress — the rotation of the TBM “Karpatka.” The machine has completed excavation of the first tunnel bore and is preparing to commence work on the second.

We are publishing information on changes to the process of issuing, sending and receiving invoices by Mostostal Warszawa S.A., resulting from the mandatory use of the National e-Invoicing System (KSeF) as of 1 February 2026.

The project contractors—the consortium of Mostostal Warszawa and ACCIONA—have completed a key stage in the construction of the tunnel on the S19 Rzeszów Południe–Babica section. The last, 11,020th concrete segment forming the tunnel’s internal lining has been installed.
