Project Description

The European Investment Bank has provided a fund for the Government of Turkey, a portion of which is to be utilized in the reconstruction of the urban roads in Düzce, Çilimli, Gölyaka, Cumayeri, Kaynaşlı, Gümüşova, Yığılca, Beyköy, Konuralp, Boğaziçi and Akçakoca which have been damaged during the 1999 earthquake. The total length of roads to be reconstructed is approximately 100 km.

The reconstruction of the roads will begin with the excavation to the necessary depth. This depth will be determined such that it will accommodate the new pavement thickness, consisting of sub-base, binder course and wearing course. In case the soil at the bottom of excavation is found to be unsuitable on which to construct the pavement, then an additional excavation is to be performed and the excavated material is to be replaced with such material whose properties are suitable and allows the construction of the pavement.

This project is executed according to the FIDIC Red Book.

Services Provided

• Monitoring and Inspection of the construction
• Quality Control of the Works
• Supervision of Cut-fill Works
• Supervision of Asphalt Pavement Works
• Final Accounts and Payment Certificates

Project Description

Project Description

This project connects the city of Çankırı to capital Ankara. The 84 km long state highway was designed as two lane dual carriage highway. The Project is implemented to provide more efficient land transport of cargo between Çankırı and Ankara. Ankara is the largest city in the middle of Turkey and is commercial social center of the region. To cope with the rapidly deteriorating traffic conditions due to ever increasing population in urban areas of Ankara the construction of the İskilip Highway Road became a definite requirement.

Project Description

The project purpose was for the preparation of preliminary and final design of 2 major interchanges and (2×3) connecting roads. The pre-existing state highway was a two lane dual carriageway intersecting the city through these two interchanges. The upgrade was for these two major intersections and related roads enhanced provide of a smoother traffic flow pattern through rush-hours during serious traffic congestion.

All of the technical studies, field investigations and related services for the detailed design stage of the project were perform finalized by BOTEK.

Estimated Construction Cost: 20 Million US $
