📋 Tender Overview
In the tunnel between Lodz Fabryczna and Zabieniec and Kaliska stations apart from the Polesie and Srodmiescie stops under construction there will be a third one - Lodz Koziny. PKP Polskie Linie Kolejowe SA signed the contract and in the place of the junction chamber at ul. Wokniarzy will build an additional stop for nearly PLN 188 million. The investment carried out with the use of OPI E funds will increase the role of railways in agglomeration and long-distance connections.The third stop Lodz Koziny will be built at the intersection of al. Wokniarzy and ul. Drewnowska at the junction of single-track tunnels two towards the Lodz Kaliska station and two towards the Lodz abieniec station. The stop will have three underground levels. Communication level - 1. On level - 2 there will be platforms for trains in the direction of Lodz Kaliska and abieniec and on level - 3 towards the d Fabryczna station. The contract for approximately PLN 188 million will be carried out by PBDiM Minsk Mazowiecki a contractor for a cross-city railway tunnel. The construction of a branch chamber with platforms for the third stop has been underway since June. Heavy equipment prepares the terrain. Then diaphragm walls - they will protect the excavation which will reach a depth of 30 m. The structure of the stop will be built - slabs bottom intermediate and ceiling.We are building the third stop Lodz Koziny which was additionally created during the design of the investment. The construction of tunnels connecting the d Fabryczna d Kaliska and Lodz abieniec stations is a great and necessary investment for d the region and Poland. It also connects the railway network and at the same time creates a kind of metro for d - said Piotr Gliski deputy prime minister minister of culture national heritage and sport.We invest domestic and EU funds in the development of railways in the d Voivodeship. The implemented projects will increase the comfort and safety of travel as well as improve the accessibility of railways. All these investments are carried out within the framework of the National Railway Program. This is the largest railway investment program in history emphasized Waldemar Buda Deputy Minister of Funds and Regional Policy.Investments implemented by PKP Polskie Linie Kolejowe SA in the area of the agglomeration and the d Province significantly increase the accessibility and role of railways as an ecological and attractive means of transport. We use the OPI E EU funds for the continuation of works - construction of connections between d Fabryczna and d Kaliska incl. d Koziny stop will be built. Thanks to budgetary funds we will provide passengers with the expected standard of service at the d Kaliska station and we will improve the efficiency of railway traffic - said Ireneusz Merchel President of the Management Board of PKP Polskie Linie Kolejowe SAPolesie and rdmiecie stops are under constructionDiaphragm walls are being built at the d Polesie stop in the area of Ogrodowa and Karskiego streets. A construction protecting the 30 m excavation is being created. At the same time collisions with external infrastructure are removed. Then the bottom intermediate and ceiling slabs will be built.At the d rdmiecie stop in the area of the intersection of Zielona Street with Zachodnia Street and Kociuszki Avenue the contractor is preparing the area. Unnecessary objects are dismantled. The structures of two buildings have been strengthened. The networks of external operators will be postponed. Specialized equipment will start work on the prepared and secured area.Katarzyna and Faustyna build tunnels for underground routesThe TBM Katarzyna machine with a disc with a diameter of more than 13 meters is boring a two-track tunnel from Stolarska Street to the d Fabryczna underground station. TBM Faustina with a diameter of approx. 8.5 m constructs the first in the area of Dugosza Street of 4 single-track tunnels that will connect the main tunnel with the d Kaliska and d abieniec stations. All segments of Faustina are already underground. TBM traveled over 200 meters and assembled 139 rings. Katarzyna drilled about 70 meters of the tunnel. She beat the water lens which influenced the pace of work. As the work progresses the so-called gantries and elements of the machine back-up.Safety is the priorityDrilling progress depends on geotechnical conditions. Machines have to go through among others waterlogged ground hard and large erratic boulders or sands. There are monitoring and control devices along the route to maintain the exact course of the tunnel. The operation of the machines is supervised by specialized personnel. The information is monitored on the monitors in the cabin inside the TBM. The special design of the TBM prevents for example subsidence of land buildings landslides and vibrations. Interference and collisions with the municipal infrastructure power heating gas water networks etc. are limited. The contractor monitors the area on an ongoing basis and performs vibration measurements . In order to increase the safety of the inhabitants of some real estates - after prior arrangements - several-day stays away from their place of residence are organized.The tunnel connects PolandThe cross-city tunnel is a continuation of the construction of the d Fabryczna station which will become a transit station from the end station. Regional and long-distance trains will be able to travel through the very center of d - on the east-west axis via d Widzew Fabryczna and Kaliska stations and on the north-south axis via d Widzew Fabryczna abieniec stations. As part of the project new stops d Polesie d rdmiecie and d Koziny will be built which will be integrated with public transport and will facilitate everyday travel for residents.
