- AO Bamtonnelstroy (MOEX: BTSTP) is a Russia-based specialized infrastructure construction and engineering company engaged in the design, development, and construction of complex underground, transport, and hydraulic facilities. Founded in 1975 and headquartered in Krasnoyarsk, Russia, the company operates as a core engineering and tunneling division within the Bamtonnelstroy-Most (GC BTS-MOST) holding group.
The company operates across multiple specialized segments, including Underground Tunneling, Urban Rail Transit, Bridge Construction, and Geotechnical and Marine Engineering. Its comprehensive portfolio of products and services comprises the construction of large-diameter railway and highway tunnels using mechanized tunnel boring machines (TBMs), drill-and-blast techniques, and cut-and-cover methods; the development of subway systems, including subterranean stations, running tunnels, ventilation shafts, and maintenance depots; the engineering and assembly of long-span railway bridges, road viaducts, overpasses, and river crossings; the execution of complex geotechnical solutions, including ground freezing, jet grouting, diaphragm wall installation, soil anchoring, and slope stabilization in permafrost and high-seismic zones; and the construction of hydrotechnical tunnels, port berths, water conduits, and drainage networks. AO Bamtonnelstroy primarily serves federal transportation authorities, state-owned railway enterprises, regional municipalities, and energy infrastructure developers across the Russian Federation, with significant operational focus in Siberia, the Far East, and major metropolitan centers.
In recent developments, the company has significantly expanded its role in the modernization of Russia's Eastern Operating Domain (Vostochny Polygon) to increase the freight capacity of the Baikal-Amur Mainline (BAM) and Trans-Siberian Railway. Major operational milestones include construction works on the second Dusse-Alin Tunnel in Khabarovsk Krai and preparatory engineering initiatives for the second Severomuysky Tunnel. In urban transit, AO Bamtonnelstroy has secured and initiated major construction works on the Krasnoyarsk subterranean rail network, deploying advanced mechanized tunneling shields. Additionally, the company has upgraded its specialized heavy machinery fleet with low-temperature tunneling equipment, enhanced strategic collaboration with domestic engineering partners for component fabrication, and streamlined operational management within the unified BTS-MOST corporate structure to accelerate delivery on critical national transport corridors.
