Progress is reaching only one metre a day instead of the planned 10 metres, or 30 metres a month instead of 300. A few weeks ago, on the site of the Faido multi-functional station, tunnellers encountered a tricky gneissic area consisting of Leventine gneiss and Lukmanier gneiss. The rock yields under the pressure of the 1,400 m mountain cover above, literally transforming the rock into sand. Special support measures have been adopted to install centimetre after centimetre a kind of steel corset at the tunnel crown. The AlpTransit management reckons that a reliable estimate of the cost overruns and delay will not be possible until the summer. To date, progress at Bodio has reached 14% on the east tube and 9% on the west tube. 15/03.

BASF MEYCO Fireshield 1350 fire protection mortar was used on this project   Sinking of 800 m-deep Sedrun shaft commenced February, 1999 by jv of Murer, Shaft Sinkers, Locher, Marti, Zschokke and CSC. April 1999.   Tenders invited for 2,646 m-long Faido access tunnel at Mairengo and Amsteg access tunnel. Also Bodio service tunnel 3,162 m-long and 5 m-diameter with two cut-and-cover tunnels at 380 m each. May 1999.   North portal to Sedrun is 21 km; Sedrun to Faido is 19 km; Faido to south portal is 16 km. Sedrun and Faido are construction accesses and will be retained as emergency exits during operation of the railway. At Sedrun there will be two crossovers together with passenger unloading facilities in separately-ventilated galleries to be excavated off-line. Amsteg access is for construction and maintenance purposes only. At this stage it is anticipated that the Sedrun section will be advanced by drill/blast on four faces off the shaft starting February, 2000. Two TBMs will drive from the north portal position towards Sedrun and another two TBMs will drive from the south portal; two TBMs will drive south from Amsteg commencing early-2002 and another TBM will drive from Bodio following on 400 m of preparatory cut-and-cover in blocky alluvial ground and 420 m drill/blast with grouting; two TBMs will drive north from Faido starting end-2002; and the final launch should be from Erstfeld in mid-2003. The south end of the tunnels will be segmentally or concrete lined, and elsewhere shotcrete, waterprooof membrane and in-situ concrete will be standard. The invert will be concreted in-situ throughout. Rock temperature will be 45 degrees C, provoking maximum air temperature of 35 degrees C and humidity of 70 %. Working temperature will be reduced by circulating cooling water to the faces from refrigeration plants on surface. Sedrun already has a 10 MW plant. Project has been divided into five main contract lots. Each of the three central lots will employ 500 men; the south lot 400 men; and the north lot 300 men. See also ch/20 – 22 below. October 1999. Shaft Sinkers of South Africa reported completion of a 800-metre vertical shaft at Sedrun. The contract also included a ventilation shaft and a cavern more than 2,000 metres below the surface. A new phase in the construction of the world's longest railway tunnel is about to begin now with the drill-and-blast of two pairs of tunnels from the cavern in both directions between the middle of next year to the end of 2007. Visit www.alptransit.ch 42/01. Click ch/19 and ch/22 To complete the first stage of AlpTransit and finance the second stage, further investment will be necessary for a total of CHF600 to 800 million. The Swiss Parliament has to approve the new funding next summer. The cost estimate for the first stage of AlpTransit - which includes a first phase with the Lötschberg and Gotthard base tunnels and a second phase with the Mount Ceneri and Zimmerberg tunnels - is CHF14.7 billion. However, unforeseen geological conditions in Faido at the Gotthard base tunnel and the decision to build a twin tube instead of a bidirectional tunnel under Mount Ceneri or safety improvements in the tunnels will cost an extra CHF520 million. Consequently, reserves dropped to CHF249 million as of 31st December, 2002. Another CHF50 million will also be submitted in Parliament for the second stage, which includes the underground crossing of the Uri valley. This stage, programmed for the 2010-2020 decade, will consist in lengthening the Gotthard base tunnel so that the line will run in tunnel on 75 km instead of 57, from Brunnen to Bodio. A final decision will be made in 2007. The Lötschberg base tunnel is 75% complete while the Gotthard base tunnel is 20% complete.
