What ÖZKA İnşaat A.Ş. does

ÖZKA İnşaat A.Ş. is a privately held Turkish general contractor headquartered in Levent, İstanbul, with operating history extending over 40 years across infrastructure, industrial, and residential/commercial construction. The company is family-controlled by the Özkazanç family: Esat Özkazanç (Chairman and Managing Partner, founding partner since 2000, formerly at Tekfen A.Ş. and Arthur Andersen), Naim Özkazanç (Honorary Chairman, formerly a Tekfen İnşaat Board Member), and Rüştü Serhat Özkazanç (Board Member and General Manager, Boston University Industrial Engineering, formerly at Arthur Anderson).

The firm executes projects as a general contractor across three segments: infrastructure (highways, viaducts, bridges, tunnels, airports, water/wastewater systems, oil and gas pipelines, refineries), industrial facilities (turnkey factories, power generation/transmission/distribution), and residential/commercial buildings (satellite cities, office towers, shopping centers). Technical capabilities include Tunnel Boring Machine (TBM) execution demonstrated on the 9.5 km, 4,250 mm-diameter Kovanlık HES tunnel and the Ø2000 mm Istanbul International Financial Center wastewater tunnel, along with conventional bridge, viaduct, and highway construction.

ÖZKA's commercial model is competitive tendering primarily for Turkish government clients (Karayolları Genel Müdürlüğü, İSKİ, DSİ, Ministry of Transport, municipal authorities, Ministry of National Defense) with direct negotiation for private sector work. Revenue is generated through project contracts won via public bidding; pricing is not publicly disclosed. The firm has recently extended into international markets with the EBRD-financed R34 road rehabilitation project in Moldova (83 km), and operates internal systems for ERP, document management, SCM, and cloud file sharing. No public listing, no disclosed funding rounds, and no institutional equity ownership are present.
