From April, division 1 has been working for the Swedish daughter company SBT Sverige on the concreting of the secondary lining of the Skärholmen highway tunnel in the complicated section under Mälaren Lake. Two 40-meter-long tubes will have concrete structures up to 4.5 meters thick, the casting is divided into walls and a vault. The tunnel on the Stockholm road bypass should be completed next year.
Work is continuing on the two-track railway Milochov Tunnel, which is located on the Púchov – Považská Teplá line in Slovakia. Division 1 is working on both portals, realizing the overfilled section and gabion walls at the western portal, while the front wall at the eastern one has been fully concreted. The total length of the Milochov Tunnel is 1,861 meters.
In the Prague city centre, division 2 is carrying on the revitalization of the Clam-Gallas Palace, a significant baroque monument originating in 18th century. In the stables, above a fountain, a fresco was recently discovered, and after restoration it will become a part of the renovated interior. The large palace will serve for cultural and social events, and the project should be finalized next year.
Construction of the Žabovřeská Great Brno Ring Road will feature division 4 in the delivery of technological equipment. Works on the one-kilometer-long communication will be divided into two parts, the tramway tunnel and the tunnel gallery. Both phases include high-current installations, ventilation, and television and control system.
Construction of German Spitzenberg Tunnel on the A44 highway, on which division 1 and BeMo Tunnelling participate, is nearing its conclusion. In April, the upper vaults of both tunnel tubes were completed. Concreting of other parts of the tunnel, including the separating walls in the tunnel cross passages, are in progress, as well as works on both portals. The almost 600-meter-long tunnel is scheduled to go into operation next year.
Division 1 will be building a 500-meter-long tramway tunnel in Žabovřeská Street in Brno, part of another section of the Great Brno Ring Road. In February, the construction of the covered section, 163 meters in length, had started at the northern portal, on the opposite side. The overfilled section will measure 5 meters. Also, the rock has been protected by steel mesh. Excavation is planned from May.
On Monday, April 19, divison 2 signed a contract for the construction of the Villa Pod Menhirem Residential House in Dolní Chabry, Prague.

Construction will start in April and should last one year and a half.
Division 3 is reconstructing a section of rails at the Prague Main Station due to the lengthening of the northern underpass to Žižkov, to the new Churchill Square complex. On a subgrade reinforced by cement stabilization, a sub-ballast layer is laid, and subsequently, after a structural test, a ballast shoulder and track superstructure are built. Construction of the underpass should be completed this summer.
On Wednesday, April 7, a grant by the Technology Agency of the Czech Republic was confirmed, supporting the project Monitoring of Parameters of Small and Large Extent Blasts by Optical Fibre Sensors. With the Safibra company and the schools CTU and VSB – TUO, division 1 will be participating in three-year research and development of new technologies for monitoring blasting works.
