Construction of Tunnels, Bridges, Yard and Formation Works From

Chainage 33+097 to 47+360 (14.263 km) Under Pakage-3 in Connection

With New BG Line Between Rishikesh and Karnprayag (125 km) in State of Uttarakhand, india. (The tunnel T5 length under my responsibility is 9700 m. two tubes total length of excavation is more than 20000 m. including cross passages.)

I worked at Polatyol Construction Company in Kuwait for government road project (RA243). My aim was to gain new experiences in earthworks, highway roads and infrastructure projects. I have done large scale excavation, filling works, super-structure for bridge intersection construction and management planning.

Project: Silifke / Mut / Ermenek Highway Tunnels Total 8000 m. double tube 5 sections tunnel. (I finished total length of 6000 m in my term.)

Mahmutbey - Mecidiyekoy metro project, which has a length of 24.5 kilometers and consists of 19 stations and the distance between the start and end stops will be covered in 26 minutes. I worked as a Besiktas station construction chief. I did 35 m. deep shaft excavation and curvet/slopes stair tunnel excavation around 1500 m. in sand strata, near by the Marmara Sea at under the sea level.

Ozgun Construction is a leading company ofKRK Holding, operates in fields of tunnelling, transportation, infrastructure, superstructure, mining, and energy. Soner Temel Engineering (STM) is among the leading Tunnelling and Infrastructure contractors in Turkey.

Responsibilities: Worked at Marmaray Project (Istanbul) as a Tunnel Engineer and Geotechnical Engineer. Marmaray Project is one of the most important project of the world due to connect Asia and Europe from below the sea. This experience let me learn how to deal with water in my tunnel excavations. Towards end of the project, I moved to Algeria with the same company for the below projects.

- Bejai La Gorge RN43 Highway Tunnel (3 tunnels - 880 m. / 635 m. 268 m.) — NATM Tunnel Chief

Responsibilities: Worked as a site - NATM tunnel engineer, following up all tunnel excavation, fortification and insulation. I generated database and prepared design accordingly. While working in this project, I have gained geotechnical experience; coordinating subsurface geotechnical site investigations including geological mapping, test pits, borehole logging, soil and rock sampling, geophysics, and laboratory testing. Projects:

Salmankas Tunnel is a road tunnel project in north-eastern Turkey. It was built to bypass the Salmankas Pass Tunnel lenght 4000m. (Altitude 8000 ft), which is on the ancient Silk Road.
