PART 3: UNDERGROUND ACTIVITY.
3ème PARTIE : ACTIVITÉ DES TRAVAUX EN SOUTERRAIN.
- The construction of 6.3 km long central part of underground line in Warsaw started in march 2010.The stations are built using the cut and cover method, two single-track tunnels - with the use of 3 TBMs. The constructions of Rondo Daszyńskiego station and Powisle station, used as TBM starting shaft started in 2011.The first TBM EPB named “Maria” was assembled in Warsaw in September 2011. The second and third TBM will start I summer 2012.The most difficult part is drilling the tunnels under Vistula River The station are constructed using diaphragm walls (20 m to 40 m deep and 1,0 m to 1,50 thick) and jet grouting bottom plague. The price is approx. 1 billion EUR ; end of works - 27th October 2013.

- A construction of a tunnel under the river Vistula in Warsaw has been finish. The tunnel will be used to transport wastewater from the left-bank part of the city to the currently modernized wastewater treatment plant situated on the right river bank. The total length of the tunnel is 1300 m. It is situated approx. 10 m below the bottom of the river. The 5.35m was used for the construction of this tunnel. The drilling started on 8.04.2011, ended 22.11.2011. The work progress was varying from 8 to 25 m per day (3 shifts, 24/7). The price of this investment was 176 mln PLN (approx. 42 million EURO).
- The construction of 1350 m long railway tunnel in Warsaw, connection line between Warsaw Central Station and Airport Terminal 2 is completed. The tunnel was constructed using cut & cover method with diaphragm walls. The price was 209 mln PLN (50 million EURO)

- The tender has been completed for the road tunnel under the Martwa Wisła river in Gdańsk. The TBM method was accepted. Two independent 950 m long tunnels will be built with internal diameter of 13.50 m, containing two-lane roadways with a 3.5 m wide emergency lane. The total length of the passage will be 1970 m including the sections to be built using the cut and cover method – 680 m as well as open approach ramps with length of 340 m.
