Since the middle of last year, the 16-kilometer long section of the Ist railway corridor has been being modernized, featuring division 3. The upgrade, financed by the Blending Call EU programme, concerns tracks, technologies, crossings, and platforms. Division 3 works mainly on the reconstruction of the track substructure and superstructure in the Poříčany station.

In the winter resort of Garmisch-Partenkirche in the German Alps, division 1 and BeMo Tunnelling are excavating the one-tube Kramer Tunnel, a part of the B23 highway. From the total lenght of the tunnel, 3.6 kilometers, by February about 2 kilometers had been excavated. The works proceed from both portals, from the south the rock is crushed by explosives, from the north mechanically.

On Wednesday, February 16, Subterra made an agreement on long-term partnership with the Třebešín Secondary Technical School in Prague. The collaboration is focused mainly on engineering and air-conditioning. Subterra will offer pupils and teachers field experience, trainings, temporary jobs, lectures, and other activities supporting professional practice and promoting technical education in general.

Divison 3 has started work on the modernization of the Žilina Railway Junction in Slovakia. The large project includes four stations, a 16-kilometer-long track and many other objects. Division 3 participates mainly by reconstructing the track superstructure and constructing noise barriers. The construction site was taken over in December, and the project should take about four years.

On Tuesday, February 9, a testing volume of explosive was blasted in Žabovřeská Street in Brno, to be used for the excavation of the tramway tunnel. The half-kilometer tube under the hill of Wilson Forest will be a part of the Great Brno Ring Road. A roughly one-kilometer-long section of the road will follow the Svratka River. Division 1 will start the excavation in April, and the whole construction should be completed in 2024.

Division 2 is carrying out a general reconstruction of the secondary school in Prague-Hrdlořezy, which will result in an intelligent, energetically self-sufficient building. The innovative project features renewable resources, advanced technologies, and environmentally-friendly materials, such special wood panels on the facade. The reconstruction should be completed in less than one year.

Below the German Kramer highway tunnel in Garmisch-Partenkirchen is a one-of-a-kind ventilation shaft, 4.5 meters in diameter. In January, Division 1 and BeMo Tunneling finished the excavation, 84 meters under the terrain level. Works have been suspended in order to protect local birds; construction should resume in July with the casting of the secondary lining.

Division 1 will participate in an excavation for the revitalization of a water line crossing under the Elbe River in Obříství. On Wednesday, Ferburary 3, the christening of the microtunnelling machine took place. Representatives of contractors and guests gathered at the entry pit on the left bank.
