GAMA History

3 friends who graduated from the Civil Engineering Department of Istanbul Technical University; Erol Üçer, Yüksel Erimtan and Uğurhan Tunçata and the contractor businessman Raif Mumcu’s paths merged with the tender of Yeşilırmak and Mertırmak Bridges in 1958. The foundation of GAMA, which has made a name for itself among the biggest construction companies of our country and in the international arena, was laid in 1959 by these partners with the establishment of GAMA Construction Limited Company in Ankara. In 1962, Fenni and GAMA Construction Group Limited Company was founded to enter the fields of mechanical, electrical and instrumentation installation, which were performed only by foreign companies at the time. With the participation of Erol Özman, who was educated at the States as a mechanical engineer, GAMA became the representative in Turkey of Babcock and Wilcox, a company considered the inventor of steam boilers. Due to the cooperation with Babcock and Wilcox, a need for young mechanical engineers who were fluent in English and equipped with engineering knowledge appeared. Today, METU graduates, partners of GAMA; Ergil Ersu, Engin Inanc, Ugur Yurdakul, Ercan Davudoglu, Gurhan Tureli, Celasin Egel and Yucel Aksoy have joined the GAMA family. Fenni and GAMA Construction Group Limited Company has successfully completed the design, material supply, manufacturing, installation, operation and service of many steam boilers and accessories.The company has aimed to turn to technology-based industrial plant construction, especially power plants that were not built by Turkish firms at that time, and within the scope of energy contracting as a subcontractor of Babcock Wilcox has successfully completed the boiler installation of the Mersin Thermal Power Plant in 1966.GAMA immediately after this success became the first Turkish company to obtain a qualification in industrial plant construction from the World Bank and with this qualification undertook the general installation of the 4 × 25 MW Mersin Thermal Power Plant in 1968 and started the era of turnkey industrial plant construction in Turkey and became the first energy contractor of Turkey. Each day, with its increasing experience, GAMA has built power plants, oil, cement, petrochemical and gas plants, factories, high-rise buildings, water treatment plants and transmission lines, bridges and various infrastructure constructions and has made important contributions to Turkey’s development and industrialization efforts and continues to do so.
