Overview
Onur Group is a diversified Turkish business group headquartered in Ankara and operating internationally in construction, infrastructure, transportation, energy, mining, industrial production, and real estate investment. Its principal identity is that of an international contractor, with a substantial emphasis on transport infrastructure and related civil-engineering work. The group’s activities extend across Europe, the Middle East, Central Asia, Africa, and other international markets, with Ukraine, Saudi Arabia, Romania, and Moldova identified among its operating locations. The group’s origins date to 1981, when Çetin İşletmeleri began operating in construction and contracting. A further organizational development took place in 1991, when Onur Çetinceviz and İhsan Çetinceviz established ONUR Taahhüt İnşaat. That company became a central vehicle for expanding into infrastructure and transportation projects. Over time, the group developed beyond conventional contracting into energy, industrial production, mining, transportation services, renewable-energy investment, and real estate development. Transportation and infrastructure have remained the most visible parts of the group’s international business. Its project portfolio has included road and other infrastructure work in countries such as Croatia, Ukraine, Moldova, Saudi Arabia, Tunisia, Oman, Equatorial Guinea, Turkmenistan, and Venezuela. The group has also undertaken energy-related and industrial projects, reflecting a strategy of combining project construction with broader investment and production activities. Onur Group has maintained a notable presence in Ukraine. During the Russo-Ukrainian War, its Ukrainian operations continued, and the group participated in reconstruction-related infrastructure work. One publicly identified project was the reconstruction of the Irpin Bridge near Kyiv, a strategically and symbolically important transport link damaged during the war. The project placed the group within the international contractor community involved in restoring Ukrainian transport infrastructure. The group’s contracting subsidiary, ONUR Taahhüt Taşımacılık İnşaat Ticaret ve Sanayi AŞ, has appeared continuously in Engineering News-Record’s Top 250 International Contractors ranking since 2009. It reached its highest reported position, number 82, in 2022 and was ranked number 92 in 2021. It was also ranked number 240 in ENR’s Top 250 Global Contractors list in 2021. The available descriptions of its international revenue indicate that transportation and infrastructure projects account for most of its reported international business. During the 2010s and 2020s, Onur Group broadened its portfolio through infrastructure, transportation, industrial production, renewable energy, and real estate initiatives. In 2024, a photograph documenting the construction of the Irpin Bridge by Onur Group Ukraine received recognition in ENR’s Year in Construction Photo Contest. The available reference material does not establish a public stock-market listing, a current chief executive, a single controlling owner, or a formal corporate website. On that basis, the group is best characterized as an active, privately held, internationally oriented contracting and investment organization rather than as a consumer-facing product brand.
History
Onur Group traces its roots to 1981, when Çetin İşletmeleri was established and began working in construction and contracting. The early business provided the foundation for a later group focused on civil engineering and major infrastructure delivery. In 1991, Onur Çetinceviz and İhsan Çetinceviz founded ONUR Taahhüt İnşaat. This organization expanded the group’s role in infrastructure and transportation contracting. Its work subsequently developed into an international business serving multiple regions, with projects associated with roads, transport links, infrastructure systems, and energy facilities. The group’s international construction activity has included Croatia, Ukraine, Moldova, Saudi Arabia, Tunisia, Oman, Equatorial Guinea, Turkmenistan, and Venezuela. These projects established transportation and infrastructure as the core of its international contracting profile. The organization later broadened its activities into transportation, energy, mining, industrial production, renewable energy, and real estate investments. During the 2010s and 2020s, Onur Group continued to diversify while retaining construction and infrastructure as central capabilities. Its expansion included industrial production and renewable-energy projects, as well as real estate development and investment. The group’s contracting subsidiary, ONUR Taahhüt Taşımacılık İnşaat Ticaret ve Sanayi AŞ, was listed continuously in Engineering News-Record’s Top 250 International Contractors ranking from 2009 onward. It reached number 82 in 2022 and held number 92 in 2021. In 2021 it also appeared at number 240 in ENR’s Top 250 Global Contractors ranking. Ukraine became an especially visible market for the group. Despite the Russo-Ukrainian War, Onur Group continued operations and investment there. It participated in reconstruction-related infrastructure work, including reconstruction of the Irpin Bridge near Kyiv. The bridge project became one of the group’s most publicly recognizable recent activities because of the importance of the route and its connection with post-damage reconstruction. In 2024, an image documenting the construction of the Irpin Bridge by Onur Group Ukraine was recognized in ENR’s Year in Construction Photo Contest. This recognition highlighted the group’s construction work rather than a consumer product or marketing campaign. The available sources do not provide a complete account of the group’s current management structure, ownership, financial results, or formal website. Its current profile is therefore best described as an active, privately held Turkish international contractor and diversified investment group.
