Młociny transport junction according to schedule
In accord with agreement clauses, the PeBeKa S.A. Mine Building Company will submit the B23 metro track and A 23 station for reception no later than August 31 this year. Until the end of September, the Warsaw Metro is supposed to receive the investment.
The Młociny junction is currently the largest transport investment in Europe. It consists of a two-track tunnel, nearly 700 meters long, a metro station over 3,500 m2 in total volume, sidetracks – a three-bay tunnel 295 meters long and the Młociny transport junction itself. The latter is a modern structure with enough surface to ensure an uninterrupted flow of passengers from the metro station to the city and suburban busses, trams and private vehicles. It consists of a 3-floor parking lot with over 700 spots, a bus station complete with terminus, tram terminus with roof, commercial venues, passenger service and maintenance. Total surface of the junction is 400,000 square meters. Its construction is connected to the modernization of outlying roads. The Młociny junction will be the first transport center in Warsaw to be this modern, integrated and to link different modes of transport. Daily over 20,000 passengers will use the junction and metro station.
- Works conclusion is not equal to station opening nor the final word in contract realization. August 31st is just the beginning of the reception and permit acquisition procedure. Perhaps the media’s doubts concerning works completion schedules were caused by a flawed understanding of construction procedures – explains Jacek Kulicki, vice-president of PeBeKa company management.
The long extent of timed scheduled for reception procedures is necessary due to the investment’s sheer size, constructional complication of the metro and the necessity to meet safety regulations. Reception will include all aspects: construction, ventilation, sanitation, electricity, every tele-technical system, toll system (gates), elevators, escalators, gas fire extinguishing in chosen rooms, tracks, train disposition, station equipment controls from the traffic officer’s room and the Ist line Central Dispatching to STP Kabaty. 72-hour trial traffic will be conducted along with fire trials. Reception schedule is mainly determined by the proper authorities, that, as external entities do not fall into the execution agreement schedule. But even the completion of final receptions is not a green light for structure opening. Coordinated efforts of many entities and acquisition of use permit are necessary for that to occur.
The PeBeKa Mine Building Company has been a part of the Warsaw metro construction for over twenty years. For a long time in the XXth century ‘80s the General Metro Construction Directorate could not find a contractor willing to take on the realization of track tunnel passage under the Łazienkowska Street. The shield drilling technology proposed by PeBeKa for the track tunnels eliminated the threat to freeze traffic on the main transport artery in the east-west line for at least two years. This was the time predicted for open dig works schedule. Drilling two track tunnels and a technical communication tunnel, each of which was 88 meters long, was executed without interruption in a way that was unnoticeable for street users. The Lubin company executed seven eastern track tunnels between the Politechnika and Marymont stations. Their total length is 5,400 meters. PeBeKa has also built the Politechnika station and the underground gallery under Bankowy Square. It has also participated in the realization of Racławicka Center.
