Marmaray construction bids due

01 Sep 2002

TURKEY: Prequalification bids are due by September 17 for construction of Istanbul's Marmaray tunnel. As well as the 1·8 km double-track submerged tube under the Bosporus linking Eminonu on the European shore with Uskudar on the Asian side, there will be 11·5 km of bored tunnel forming an underground route across central Istanbul with four stations.

Other parts of the contract will cover rehabilitation of the Gebze - Haydarpasa and Sirkeci - Halkali suburban lines, rebuilding 35 stations, provision of new rolling stock maintenance facilities, upgrading the electrification and renewing electro-mechanical installations. Completion is expected to take four years. Costed at US$2·5bn, the scheme will be partly financed by the Japan Bank for International Co-operation.

  • Istanbul's Electricity, Tram & Tunnel Authority (IETT) has awarded construction contracts for three sections of tramway. Transtroy-Turan Hazinedaroglu-Univar was selected to build the Eminonu - Kabatas, Vezneciler - Edirnekapi and Sultanciftligi - Edirnekapi lines. These are part of a 4000bn lire capital investment programme (RG 2.01 p82).
