Founded by the Honorary President Mr. Mete Bora and presently managed by the Chairman of the Board of Directors Mr. Selim Bora and board member, CEO Mr. Fatih Bora, Summa Turizm Yatirimciligi A.S. was established in 1989 in Ankara to undertake international construction projects as General Contractor. The company started its construction activities abroad in 1990 with "Gara Altin” Presidential Guest House Project in Ashgabat, the capital of Turkmenistan, which was completed in less than 11 months period. Throughout 21 years of its operation, Summa has successfully completed more than 70 turn-key projects in 5 different countries and delivered more than 1 million m2 of closed area. 

Onur company which has overcome important projects on highway construction, road reconstruction and rehabilitation started in the sector in the name of
Çetin Enterprises. Çetin Enterprises Company has became successful completing several projects in various district regions of Turkish Republic General Directorate of Highways, between the years 1981-1990. Afterward,considering the increasing demand for the infrastructure Works, Onur Contracting Transportation and Trading Ltd. Company (Onur) was established in 1991.

Onur Company has carried out large scale, very important construction works not only in Turkey but in countries such as Croatia, Ukraine, Turkmenistan, Tunisia and Saudi Arabia. Construction activities of our company still continue at countries such as Saudi Arabia, Umman, Ukraine, Turkmenistan and Equatorial Guinea.

Onur Company’s major goal is to complete the works on time and in good quality. For this reason, we always prefer to work with qualified and experienced staff, with the help of the most modern and powerful equipment. Since quality is one of the most important criteria for us, we have Quality Control Laboratories in the Main site as well as in every Project site. We perform any kind of experiment and test such as Soil Test, Concrete, Bitumen and the Mixtures with Bitumen Tests. Moreover, the prepared mixture design has been observed carefully in the production phase.

Onur Taahhüt, Taşımacılık ve Ticaret Limited Şirketi, having TS-EN-ISO 9001 and ISO 14001 Quality and Environment System Certificates, works successfully in the sector of Highway Construction and is one of the leading companies in Turkey in terms of qualitative works. As a result of the quality works and the timely completion of contracts, Onur Taahhüt, Taşımacılık ve Ticaret Limited Şirketi has been well recognized abroad and was awarded with an ‘’Outstanding Service Award‘’ by the President of Ukraine.

Here are some current projects in other countries:

Reconstruction and rehabilitation of highways, state roads, bridges, interchanges and crossroads, with construction machines located in three different
Project sites, in Ukraine. Excavation, filling and hot mix bituminous asphalt paving Works of Enfidha Airport Runway-Apron-Taxiway (RAT) construction in Tunisia. Infrastructure Works of King Abdullah University and King Abdullah Economic City in Kingdom of Saudi Arabia.

Onur has enough number of Machine and Equipment which enables itself to perform many infrastructure works at different locations at the same time. All
the Machine and Equipment have been repaired and maintained by qualified personnel located in the main worksite of the company.

What the important thing about our Machine and Equipment is the renewal of the old and overused machines with new brand and multifunctional ones. Onur Contracting, Transportation and Trading Ltd. being a young, dynamic, innovative and ambitious company is a member of Turkish Contractors Association (TMB), Turkish Asphalt Contractors Association (ASMUD) and the Foreign Economical Relations Board (DEİK).

Onur Company has been ranked 12th among Turkish contractors and 150th according to the Engineering News Record (ENR) ranking of the Top 225 International Contractors in 2010.

Onur is always eager to follow the tenders and does its best in order to take part in such tenders regarding infrastructure projects both in Turkey and in other countries.

It all began on 29th of November 2010 on a shiny day of Tripoli, on the Terrace of Radisson Blu Al Mahary Hotel in Libya.

Me and Mr. Onur Çetinceviz were looking at the beautiful bay area from the 15th floor of the hotel when the General Manager Mr. Chauve stepped in and said that the President of Equatorial Guinea wants to meet with the owner of the hotel.

We noticed that His Excellency Teodoro Obiang Nguema Mbasogo was our guest who just checked-in to the Presidential Suite in order to participate African Union Summit 2010 with his delegation.

We asked from the head of his protocol Mr. Evuna for a proper time to see him during his stay with us. The same day he gave us an appointment at 10:00 pm at the executive lounge of the hotel where we had the pleasure to meet him in person for the first time.

The meeting which took about one hour gave us the opportunity to present both companies SUMMA and ONUR to His Excellency .

During the meeting I mentioned to His Excellency President about Hotel, Towers, and other construction projects we have completed in Libya by showing him from the terrace of the hotel while he was mentioning about the satisfaction and the good words he heard from Libyan officials about SUMMA for quality and speed of construction projects the company undertook so far.

We mentioned that although ONUR does not work in Libya, it is a worldwide known road and Infrastructure Company capable of executing fast track projects.

At the end of the meeting the President asked both companies to visit his home country as soon as possible to discuss construction project of a conference halland airport infrastructure whereas both projects were supposed to be done in fast track manner.

After having received such an invitation from thehighest level of a State, we did not even think twice and accepted immediately the invitation to make this first visit which demonstrated typical reflex shown by Turkish contractors which later on turned into a world record fast track design and build construction project from scratch.

On the 6th of December exactly 1 week after our meeting in Tripoli, Me, Mr. Onur Cetinceviz, Mr. Hakan Caka, Mr. Faruk Yıldırım and Mrs. Melkan Tabanlioglu flew to Malabo, Capital of Equatorial Guinea to find out the details about what was needed to be done. On the same day we were asked to visit the job site together with the President.

The moment we were at job site we realized that His Excellency President had concerns about the design and capacity of the existing facilities thus wanted us to tell him what kind of a more proper annex building we could build in 5 months.

He gave us only two parameters;

a. To build a conference hall in such a way that it could be capable to host 60 Heads of States and 5 delegates of each.

b. To finish the building on turn-key basis by the 5th of June 2011.

The next day we returned back to Turkey in order to prepare a concept design for further approval of His Excellency President who asked to meet again on 15th of December 2010.

In 9 days we completed the concept drawings and flew back to Malabo on 16th of December the date when His Excellency President approved all the architectural design works completely.

Then we started thinking about how to build such a huge conference center without having any idea about availability of local goods and services.

Then we found out that the availability of local goods and services necessary to build this project were limited (considering the time constraint we had while we were promising H.E. President) to deliver the project on time with desired quality.

We realized the complexity of the logistics andtook immediate measures to catch the deadline. All departments worked in harmony. 1600 tons of structural steel has been manufactured in a record short timeand shipped to job site for further installation. No need to mention about all other disciplines doing the same where otherwise would be impossible to reach this result.
