Kyrgyzstan, Taldyk Pass - kg/11


A 2,000 m tunnel alternative under the Taldyk Pass at an altitude of 3,000 metres is under study by Finnroad as part of the improvement of the Silk Road between Osh and Erkesh Tam. The tunnel will not be feasible before the volume of traffic is sufficient. It would be a single tube, 11 m-wide including pedestrian sideways. Expected geology is limestone. Drill/blast method. Support with rockbolts, shotcrete and steel arches, if needed. The timing of the project depends on political decisions yet to be made by China, Uzbekistan and Kyrgyzstan. Excavation is roughly estimated at $20 million. Financing by loans from Chinese international financial institutions. The client will be the Kyrgyz ministry of transport and communications.

Laos, Bolikhamxai and Khammouan Provinces - la/11


Completion of first project on the Nam Theun river, largest tributary of the Mekong river. Located 100 km above the confluence. 210 MW power station and headstocks are above ground. Recchi-CMC, a consortium of Italian construction companies, excavated 5.5 km-long, 45 sq m-section low pressure headrace tunnel between the upper Nam Theun and the lower Nam Hinboun reservoirs where the difference in elevation is 240 m. Tunnel will transfer 110 cu m/sec of water. Three identical 12 m-long self-propelled steel forms with hydraulic winches to enable the equipment to tackle 14 % gradients were supplied by CIFA Spa along with 5 cu m concrete mixers mounted on Astra 4WD dumpers and trailer-mounted concrete pumps. Average 28 m/day of lining completed over five-month period. Visit www.cifa.com for more information. December 1999.CMC signed a EUR180 million construction contract for the Theun Hinboun expansion project. The project is the expansion from 220 to 440 MW of the installed capacity of the existing hydroelectric power plant originally built by Recchi-CMC JV in 1995-1998.

Lebanon, Mount Lebanon Governorate - lb/13


The Government of Lebanon (GoL) intends to build an Expressway from Khaldeh to Nahr Ibrahim on a PPP basis. Total length of the expressway is 38 km divided into a tunnel section of 12 km and a dual 3-4 lane expressway of total length approximately 20 km, Interchanges, service roads and bridges.  GoL might consider splitting the execution of this expressway into different standalone sections for ease of implementation and for securing the funds for the expropriation.

Starts at the town of Khaldeh South of the city of Beirut and heads northward through Choueifat, Hadath, Hazmieh, then Dikwaneh, Baouchrieh, Jal El dib, Antelias before it connects to the existing Northern Highway at Dbayeh north of Beirut. A new tunnel from Dbayeh to Nahr Ibrahim.
