What Gap Construction does

Gap Construction (Gap İnşaat Yatırım ve Dış Ticaret A.Ş.) is an international EPC and turnkey construction contractor founded in 1996 and headquartered in Istanbul, Turkey. The company is a wholly-owned subsidiary of Çalık Holding, a diversified Turkish conglomerate, and operates across four core verticals: infrastructure (seaports, highways, airports, water treatment), industrial (power plants, fertilizer and cement plants, mining facilities), healthcare (hospitals and specialized medical centers), and superstructure (residential, commercial, and government buildings). It maintains 6,704 employees and runs 10+ country offices spanning Turkey, Turkmenistan, Iraq, Qatar, the UAE, Saudi Arabia, Libya, Kazakhstan, Kenya, and Poland, and has delivered 146+ projects across three continents with a cumulative contract value of $8.56 billion.

The company's core technology is large-scale EPC delivery, with notable flagship projects including the $1.5 billion International Turkmenbashi Seaport (the largest port on the Caspian Sea), the $1.3 billion Garabogaz Ammonia and Urea Production Plant (built with Mitsubishi Corporation), and a portfolio of large healthcare facilities in Turkmenistan such as the 500-bed International Oncology Hospital and the 400-bed International Rehabilitation Center. It has been continuously listed in the ENR Top 250 International Contractors since 2006, reaching 142nd place in 2025, and holds ISO 9001, ISO 14001, and ISO 45001 certifications with a 22 million man-hour zero-accident record.

Gap İnşaat generates revenue almost entirely through project-based EPC and turnkey contracts negotiated directly with government ministries and state-owned enterprises, primarily in Turkmenistan and Iraq. Pricing is project-specific and undisclosed, with no standardized rate card. Customers are predominantly sovereign (Turkmenistan Ministries of Health, Energy, and Transport; Iraq Baghdad Municipality; Republic of Turkey), with a small enterprise tail (e.g., Emlak Konut Gayrimenkul). Sales cycles are long-term, involving competitive bidding and direct contract negotiations, and revenue is recognized over the construction period of each contract.
