[8] The company has been involved in the construction of power plants,[2] airports,[9] bridges,[8] pipelines,[8] motorways,[10] business towers[11] and shopping centers.

[3] The company has carried out around 500 projects in more than 30 countries including Albania, Algeria, Cameroon, Kazakhstan, Libya, the Netherlands, Nepal, Oman, Romania, Russia, Saudi Arabia, Sierra Leone, Tajikistan, and Ukraine.

[17] After the breakup of the Soviet Union, Enka delivered goods and services, ultimately building a strong business relationship with Russia.

[18] In the mid-1990s, Enka built a second investment company, Moskva Krasnye Holmy, building offices, shopping centers, and recreation facilities across Russia.

[23] In the early 1970s, Enka, in a partnership with German company Wayss and Freytag, built the Ortaköy viaducts and the Bosphorus Bridge.

[23] Enka continued to expand internationally in the 1980s with the award of the 1981 housing development contract in Al Medinah, Saudi Arabia, in a joint venture with the company Kutlutas.

[28] Enka undertook various construction projects in the late 1980s and the beginning of the 1990s, including the Bekhme Dam in Iraq,[29] the Petrovsky Passage in Russia,[30] and the Ankara-Gerede Motorway, in a partnership with Bechtel.

[32] In 1997, Enka and Bechtel were awarded the rights to build and operate the Gebze, Adapazarı, and Izmir gas power plants.

[40] In April 2010, the Enka-Bechtel partnership was awarded a contract for the construction of the 78 kilometre Route 7 four-lane motorway from Morine to the north of Pristina in Kosovo, and finished a year ahead of schedule in November 2013.

[9] Enka was awarded an engineering, procurement and construction (EPC) contract to convert the Erbil Independent Power Project from simple-cycle to combined-cycle technology and began work in summer 2012.

The structural design of this project is comparable to the first two generators at the Berezovskaya power plant, but features an upgrade to increase efficiency and reduce nitrogen oxide emissions.

[44] Enka was the lead contractor for the engineering, procurement and construction of the Sulaymaniyah 1,500 MW Combined Cycle Power Plant Project in Iraq that began in 2013.
