ALKE Group of Companies

What ALKE Group of Companies does

ALKE Group of Companies is a privately-held Turkish EPC (Engineering, Procurement, Construction) contractor founded in 1955 by High Civil Engineers Hazım Alakavuk and Ayhan Kemaloğlu in Antalya, now headquartered in Florya, Istanbul and led into its third generation of family ownership. The company delivers integrated design-to-turnkey construction services across infrastructure (dams, roads, tunnels, water and sewerage systems), superstructure (stadiums, hospitals, schools, residential, hotels, industrial facilities), water and wastewater treatment plants, energy production facilities including hydroelectric plants, and offshore construction. With 600+ completed projects across 10+ countries — including Kazakhstan, Oman, Russia, Romania, Ghana, Maldives, Azerbaijan, and Kyrgyzstan — and a 300+ professional staff, ALKE serves primarily government and public-sector clients through competitive tendering.

Core technical capabilities include tunnel construction via drill-and-blast methods (most notably the Istanbul Melen Project, a 13,586m cross-continental subsea water transmission tunnel between Asia and Europe), advanced biological wastewater treatment with EU Urban Wastewater Directive-compliant dual-line nitrogen and phosphorus removal systems (up to 105,000 m³/day capacity at Samsun East), and in-house manufacturing of prestressed concrete pipes (ÖG.B.B) and prefabricated products through dedicated İzmir facilities. The company also built Europe's largest integrated wastewater treatment plant (Ambarlı) and delivered landmark facilities such as the 30,000-seat Astana Arena stadium.

Revenue is generated through one-time EPC project contracts obtained via competitive government and international development tenders, supplemented by hardware sales from manufacturing operations. Pricing is project-based and not publicly disclosed. The company divested its wind turbine tower manufacturing business (Ege Kule A.Ş.) to South Korea-listed CSWIND Corp. in 2018, exiting that vertical to refocus on core EPC delivery. ALKE maintains no public listing, no disclosed institutional investors, and no public revenue figures.
