What Nurol Construction does

Nurol İnşaat ve Ticaret A.Ş. (Nurol Construction) is a privately-held Turkish general contracting firm founded in 1966 and operating as the flagship entity of Nurol Holding. The company delivers large-scale infrastructure projects under Engineering-Procurement-Construction (EPC) contracts, spanning highways, bridges, viaducts, tunnels, dams and hydroelectric power plants, urban metro systems, and industrial facilities. Core technical capabilities include balanced cantilever bridge construction, tunnel boring machine operations, and immersed tube tunnel work, exemplified by the Osmangazi Bridge (world's 4th largest suspension bridge), Ilisu Dam (1,200 MW), and Marmaray BC1 (world's deepest immersed tube tunnel). The company maintains wholly-owned regional operating subsidiaries in nine countries — Romania, Algeria, Georgia, UAE, Libya, Iraq, Saudi Arabia, and Slovakia — in addition to its Istanbul (Maslak) headquarters, and is ranked 132nd in ENR's 2025 Top 250 International Contractors.

The business model is project-based: revenue is generated through competitive international tenders issued by government agencies and state-owned enterprises, with a mix of lump-sum turnkey and cost-plus arrangements. Customer concentration is overwhelmingly on public sector clients, including Turkey's KGM (General Directorate of Highways) and DSI (State Hydraulic Works), the Istanbul Metropolitan Municipality, and Romania's CNAIR. Notable joint ventures include Gülermak-Nurol-Makyol (Ümraniye-Ataşehir-Göztepe Metro), Nurol-Cengiz (Dicle River bridge), and Nurol-Yüksel (Ordu Ring Road). The company employs 8,000+ staff including direct employees and subcontractors, and has cumulatively delivered $30B+ in project value, 1,600+ km of roads, 3.6M+ m² of building area, and 1,900+ MW of hydroelectric capacity.

The go-to-market is purely enterprise sales-led, with no retail or indirect channels. Distribution is executed through direct registration and bidding on government tenders, supported by country-level business development teams and a multilingual corporate website (Turkish, English, French, German). Financing capacity is a critical operational driver: in December 2025, Nurol closed a US$300 million syndicated term loan facility arranged in the Gulf bank market by Emirates NBD and First Abu Dhabi Bank, one of the largest syndicated corporate loans for a Turkish corporate in recent history. The company is led by CEO Nurettin Akdeniz and CFO Nurdogan Topuz, and is certified under ISO 9001, 14001, 45001, and 39001.
