Golden Drill for PeBeKa

Published 16 April 2009

The PeBeKa S.A. Mine Building Company from Lubin has been awarded the prestigious „Golden Drill”, second prize in the public buildings category, for the A-23 Młociny station, last stop on line I in the Warsaw metro. The competition was organized for the thirteenth time by Bosch-Elektronarzędzia. 60 companies from all over Poland took part.

The acknowledged A-23 Młociny station is the last station in the Bielany section of Warsaw’s metro. It was built as a monolithic construction with the use of slotted walls. It consists of one underground floor and two surface pavilions serving as platform entrances. The platforms, each 4.5 meters wide and 120 meters long, are located on the station’s sides with the tracks in the middle. In between the tracks runs a row of illuminated columns. The station lies along Kasprowicz Street, on a junction of Nocznicki and Kamiński Streets, in proximity of the foundry. The station, along with a three-bay sidetrack tunnel is 450 meters long in total and has a volume of 78,530 cubic meters in the underground part and 9,500 cubic meters in the surface part.

- Works at the Warsaw metro are an enormous endeavor in the midst of cityscape. It is a challenge on a scale hitherto unknown in Poland. The structure looks impressive, every day it is used by dozens of thousands of passengers. We are extremely proud of the awarded distinction – says Ryszard Janeczek, president of PeBeKa company. – Investments of this type are an unusual task not only for the engineers, but also for the whole staff, which has to integrate construction works with consultations at various institutions and media suppliers.

The Młociny station, designed by Metroprojekt and AMC Chołdzyński consortium, stands out thanks to its unique finishing, including elements like the wavy ceiling, chalice-like pillars between tracks, surface pavilions surrounded with stone blocks behind steel bars. Interior design is kept in shades of gray with wood-imitating details. Two escalator strands and two elevators lead to the door. North lies the supply track chamber, where trains are turned around. The station and track arrangement were built with future metro line extensions in mind.

Construction works on the last part of the Bielany metro section including the two-track 700 meter tunnel, the A-23 station, the sidetracks – three-bay 295 meter tunnel and the Młociny transport junction itself, took over 28 months. This gigantic investments was supported by nearly 190 subcontractors and supply firms. In the peak work periods as much as 500 people worked on site daily in two shifts, some even in nighttime. The construction area was over 10 hectares.

The Młociny junction is currently the largest transport investment of its kind in Poland, fusing various modes of transport: bus station with terminud, covered tram terminus, car park for almost 1,000 vehicles, and allowing for a collision-free movement of passengers between them as well as conducting services in commercial and technical venues. Total surface of the junction in 400 thousand square meters. Its construction involved complete rebuilding of outlying roads, including the future erection of the North Bridge. The whole takes up 1.5 a hectare, houses 2.3 kilometers of rail tracks, 17 train junctions and 7 criss-crosses.
- We have drawn upon previous experiences gained while realizing foreign and domestic contracts, where we have already faced investments executed in the midst of a city – emphasizes Ryszard Janeczek. – The mining experiences in underground construction at the Copper Industrial Area gave us the chances to be up to new and difficult challenges.
The PeBeKa S.A. Mine Building Company has been part of the Warsaw metro construction for over twenty years, executions including: over 6 km of track tunnels Słodowiec and Politechnika stations, Racławicka Center, gallery under Bankowy Square.
