Mostostal Warszawa signed a PLN93.4 million contract with a consortium of PRG Metro and PeBeKa to build Slodowiec metro station (A20) and a manoeuvring side track (B21) on Line 1 of the Warsaw metro. The scope of the works encompasses comprehensive execution of the Slodowiec station and a crossover section behind it with switches and a 207 m-long siding (B21). This will allow for the trains to turn back and the Slodowiec stop to be fully operational even when the works on the remaining sections of the northern extension of Line 1 between the station and the future terminus at Mlociny (A23) are still in progress. The 155 m-long station will be built in 60 cm-thick structural slurry walls utilizing the "top down" method. Mostostal will build the three consecutive stations for Warsaw's metro system: Slodowiec (A20), Stare Bielany (A21) and Wawrzyszew (A22), including the track tunnels in between. This represents a total of about 2 km.

Both stations and the connecting tunnels comprise the longest segment through the Bielany district, which is the northern, terminal segment of the first metro line in Warsaw. The route will pass through areas free of immediate buildings, characterised by a much lower concentration of infrastructure than in the centre of the capital, which is why the whole stretch of the line will be executed in slurry walls using the cut-and-cover method. The double-track tunnel B21 between Slodowiec and Stare Bielany stations, which is 773 m long and 9.8 m wide, has been designed as a two-aisle monolithic reinforced concrete box, with a row of dividing columns in the middle, to be executed in an open trench. The B22 tunnel between Stare Bielany and Wawrzyszew stations, with internal dimensions of 4.8 m by 8.85 m and length of 655 m, will be built using the "top down" method with 60 cm-thick structural slurry walls. The tracks will be located at depths ranging from 4.5 to 9 metres below the surface. The Stare Bielany station (A21), comprising three 182.5 m-long aisles, will be built by the "roof first" technique. The 149 m-long Wawrzyszew station (A22) will be executed in steel anchor shoring with cut-and-cover method. The assignment will be executed in the record time of fifteen and a half months and will be completed by October 2007.
