Seven consortia have expressed interest for a road scheme, a part of which requires an undersea tunnel in the harbour. They are: Siragga Thermaikou (Vinci, JNP, Avax, and Etaria Teknikon Thessaloniki); Transport Thessaloniki (Strabag, Bilfinger Berger and Aegek); Thermaiki Odos (Helliniki Teknodomiki, Aktor, Boskalis International, Archirodon, and Themeliodomi); an unnamed consortium (Bouygues, Autoroutes du Sud de la France, Alte, and Volker Stevin); Possidon (Hochtief, Dragados, Ballast Nedam, and Athena); Philippos (Impregilo, GEK, Terna, Avete, Ampedos, and NCC); and finally Thescros (FCC, E. Pihl & Sí¸n, Cl Sarantopoulos, Pantexniki, Attikat, Macquarie International, Peiraios Bank, and Cowi). The winning bidder will design, build, finance, maintain and operate the road under concession. The project is budgeted at €320 million. The Greek government is to contribute up to €60 million. 41/02.Six out of seven candidates have been prequalified for the harbour tunnel. Consortium Philippos led by Impregilo is the only eliminated. The remaining candidates will be invited to collect the design plans this week and the invitation to tender, technical documents and draft concession agreement will be sent in August. A three-month period will then open for the candidates to submit their offer, which is planned in November 2003. A committee will assess the bids and recommend a preferred bidder, which is planned by year-end or in early 2004. Then, the client should close a financial deal and assign the contract, which is estimated to take another four months. Finally, the project will be submitted to Parliament approval. The tunnel will comprise an immersed section (2 x 1,240 m) with two connecting land tunnels at each side (2 x 1,086 m and 594 m + 1,072 m). 29/03.Five consortia have submitted technical and economical offers for the concession contract for the harbour tunnel which includes an immersed section (2 x 1,240 m) and two connecting tunnels at each end (2 x 1,086 m and 594 m + 1,072 m). They are Tunnel Thermaikou (Vinci SA / Vinci Construction Grands Projets / J&P-Avax / Etheth / Cofiroute); Poseidon (Hochtief Projektentwicklung GmbH / Hochtief Construction / Dragados Concesiones de Infraestructuras / Dragados Obras y Proyectos / Ballast Nedam / Athena); Trans Port Thessaloniki (Strabag / Bilfinger Berger / Aegek); Thermaiki Odos (Elliniki Technodomiki / Aktor / Boskalis International / Archirodon Group / Themeliodomi); and Bouygues TP / ASF / Alte / Volker Stevin. The preferred bidder is expected to be announced in March 2005. Estimated cost is EUR322.8 million. 49/04.Thermaiki Odos, a Greek-Dutch consortium including Elliniki Technodomiki, Aktor, Archirodon Group, Themeliodomi and Boskalis International, won the tender for a 30-year concession contract for the Thessaloniki harbour tunnel including an immersed section (2 x 1,240 m) and two connecting tunnels at each end (2 x 1,086 m and 594 m + 1,072 m). The offer submitted by the consortium puts the contribution of the Greek government to construction and operation at EUR66.5 million. Construction will take four years once the contract is signed. The estimated cost of the tunnel is EUR322.8 million. 20/05.Following unprecedented delays, the concession agreement for the Thessaloinki submerged tunnel was signed on 31st October, 2006. The agreement ties in the Greek Ministry of Public Works, the concession company Thermaiki Odos, and the initial shareholders to the completion of the deal. The project cost is EUR472 million, of which about EUR100 million will be funded by the Greek State, EUR60 million from the sponsors, whilst the remainder is put up by the commercial bank and EIB loans. Hellenic Technodomiki has a 50% stake in the venture while Archirodon and Boskalis control 32.5% and 17.5% respectively. The consortium will build a 6.5 km underwater tunnel and operate the concession for 30 years. The project must still be ratified by parliament and construction is expected to begin by March 2007 and complete in four years. Click gr/23. 45/06.

October 1999.Open call for bids, deadline 28th July, 2004 for completion of the Kallidromo tunnel on the Tithorea-Lianokladi section of the Athens-Thessaloniki line. A length of 2 x 6 km remains to be bored. To date, 3 km has been excavated but construction was stopped last year due to geological difficulties. Tender budget: EUR239 million. Visit http://ted.publications.eu.int/udl?request=Seek-Deliver&language=en&docid=093335-2004, OJ S 111, or contact Erga Ose, Athens, fax +30 2105283392. E-mail pakoukou@ergose.gr 25/04.Open call for bids, deadline 21st April, 2005 for completion of the Kallidromo tunnel on the Tithorea-Lianokladi section of the Athens-Thessaloniki line. The tunnel has two single track tubes, each approximately 9,260 m long. The Thessaloniki-bound right tube is 9,259.5 long while the Athens-bound left tube is 9,261 m long. The distance between both tubes ranges from 35 m to 65 m. Crosscuts are constructed every 500 m. Each cross section is 8.9 m wide and 9.2 m high. The height over the railtracks is 7.6 m. Every 25 m safety niches will be constructed on either side of the tunnel. Under a previous contract, 5,841.6 m of the tunnel has already been driven, 2,809.54 m of which from the south portal (1,437.99 m in the right tube and 1,371.55 m in the left tube) and 3,032.07 m from the north portal (1,589.68 m in the right tube and 1,442.39 m in the left tube), but construction was stopped in 2003 due to geological difficulties. The total remaining tunnel length to be excavated is approximately 12,230 m long, whereof 6,007.5 m in the right tube and 6,222.5 m in the left one. The remaining tunnel length where the final lining is to be installed is 13,025 m long (6,512.5 m in each tube). Six crosscuts were excavated, three of which from the south drive and three from the north. Cut-and-cover sections already built both at the south and north ends (south drive: 39.04 m in right tube and 37.86 m in left tube / north drive: 100.79 m in right tube and 138.2 m in left tube). To save construction time, the inner lining will be installed concurrently with excavation and support. Spoil removal (by loaders and trucks) and transport of construction materials through the crosscuts. Within the scope of the geological investigations, 14 sample boreholes were drilled and a detailed geological mapping of the project area was performed. The expected geological formations are a mix of clay and marl from km 6+625 to km 7+000 and conglomerate breccia from km 7+000 to km 7+090. The overburden is 150-220 m. To the south, at km 7+090 - 8+385 (right tube) and to the north at km 10+860 - 12+687 (right tube), limestone is expected. The overburden ranges between 160 and 360 m approximately. In the central section, between km 8+385 and 10+860 (right tube), the tunnel runs in a complex consisting of ophiolite layers. Serpentinite (SE) and schist serpentinite (SES) is mainly expected. In this section the overburden ranges from 300 to 530 m approximately. The Kallidromo tunnel will be excavated using the NATM method, according to the approved design. In the tunnel central section, advanced investigative drillings will be performed to identify zones with very low rock mass strength. During construction, the owner will implement an extended monitoring programme together with back analysis, to develop a comprehensive database to correctly select the suitable excavation and support methods. The tunnel will be excavated from four drives, simultaneously from the north and south faces. In the clay, conventional tunnelling in cross section of approximately 130 sq m, with support by means of fibre-reinforced shotcrete, approximately 40 cm thick, wiremesh, self-drilling anchors and fully grouted bolting, and fibre glass nails as temporary support at the face. In the limestone, drill/blast method in one or two phases in cross section of approximately 100 sq m, support by fibre-reinforced shotcrete, approximately 10 cm thick, and fully grouted sporadic bolting. In the serpentinite, drill/blast method or conventional tunnelling in one or two phases in cross section of approximately 110 sq m, with fibre-reinforced shotcrete, approximately 20-30 cm thick, wiremesh, steel arches, self-drilling anchors and fully grouted bolting, and fibre glass nails as temporary support at the face. Final reinforced concrete lining with a 25-60 cm thick metal formwork. Contractors are required to have constructed NATM tunnels (temporary support plus final lining) with minimum length of 2,300 m and cross section larger than 50 sq m. This is a rebid. Tender budget: EUR239 million, of which EUR188.1 million for the tunnel itself.
