ALARKO

What ALARKO does

Alsim Alarko Sanayi Tesisleri ve Ticaret A.Ş. (Alarko Contracting Group) is a privately held Turkish EPC general contractor founded in 1954 and operating as a subsidiary of diversified conglomerate Alarko Holding. Headquartered in Beşiktaş, Istanbul, the company delivers large-scale infrastructure and industrial projects across seven service categories: refineries/chemical/petrochemical plants, oil/gas and pipelines, transportation (metros, railways, highways), housing and buildings, power plants, industrial plants, and water/wastewater treatment facilities. Its project footprint spans Turkey, Kazakhstan, and Romania, with historical execution in Iran, Russia, CIS states, Ukraine, and Turkmenistan, totaling 350+ projects across three continents. The company has been continuously listed in the ENR World's 250 Largest International Contractors since 2004.

Technically, ALARKO's core capability centers on complex heavy-civil and industrial construction, exemplified by tunnel boring machine operations (the St. Maria TBM with a 6.6-meter cutterhead, 600-ton weight, and 1.5 meters/hour continuous excavation used on the Bucharest M6 Metro) and the construction of Istanbul's deepest metro station (Yıldız at 75 meters). It holds ISO 9001, ISO 14001, and ISO 45001 certifications and operates under a stated net-zero carbon target by 2050, with active digital transformation initiatives covering robotic process automation, AI, and IoT tools.

The business model is project-based EPC contracting won through competitive public tendering with national governments, municipal authorities, and international development institutions (EBRD, EDB, IsDB, JICA). Revenue is recognized via multi-year design-build contracts structured in distinct design and construction phases. The customer set is concentrated in sovereign counterparties (Metrorex, National Road Administration Company SA Romania, Kazakhstan Government, Istanbul Metropolitan Municipality), with the BAKAD ring road representing the company's first build-operate-transfer concession and a transition into recurring operational revenue.
