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. Visit www.alptransit.ch and www.blsalptransit.ch 15/03.Following an out-of-court agreement between the project owner AlpTransit Gotthard and Schweizer Bahntechnik Konsortium and once the contract is signed, which is scheduled for spring 2008, Transtec Gotthard will draw up the implementation plans to begin installing railway technology in the Gotthard base tunnel in 2009. On 4th May, 2007, Transtec Gotthard was awarded the contract for railway technology but the decision was attacked in justice by the defeated consortium Schweizer Bahntechnik. Read E-News Weekly 24/2007. The order is worth CHF1.69 billion and construction is scheduled to last until 2016.

Visit www.kuma.ch, www.ewi.ch or www.poyry.com and www.scheuchzer.chOnce the federal office of transport has granted its approval, work on installation of the railway technology systems is scheduled to begin at the south portal in Biasca around the beginning of 2009, and at the north portal in Erstfeld around 2012. The construction period is around seven years. The Gotthard base tunnel is scheduled to go into commercial operation in 2017. The work covers installation of railway technology facilities in the two one-track tunnel tubes, each 57 kilometres in length, and the outdoor routes connecting the existing rail network. The railway technology to be installed includes the track, power supply and cabling, lighting and power installations, overhead lines and switching stations, tunnel instrumentation and controls, data networks and operational communications, tunnel communication systems and signal boxes, process control systems and a new signalling and train security system.Before these systems can be installed in the tunnel, extensive systems for logistics and transport such as construction railway, workshops, storage depots, accommodation, ventilation and air conditioning systems, power supply, radio and telephone systems need to temporarily set up. Visit www.alptransit.ch 03/08.Pöyry has been awarded an engineering services contract in the Gotthard base tunnel project by the Swiss Transtec Gotthard consortium.

May 1998.  North tube breakthrough by Herrenknecht 11.7 m-diameter TBM achieved May, 1999 by contractors GTG, a jv of Marti, CSC, Comina and Pierre Freiburghaus. TBM dismantled and taken back to start for south tube to complete by October, 2000. Maximum daily advance 21.6 m with average of 13 m. Steelcord muck conveyor from TBM to portal with 400 m cassette. Korfmann fans and Grindex Matador pumps. Segment prefabrication at site produces six 1.8 m rings/day using forms supplied by Bernold and CBE. 28 cm-thick ring comprises 5 x 9 t segments plus key. Sept 1999.

Will drive 3.1 km over next three years to explore geological conditions for the 15 km Mt Ceneri base tunnel. Has advanced more than 2 km at 6 m/day. April 1999.   Mt Ceneri is on southern access to Gotthard base tunnel. Sigrino exploration drive underway on a 30 sq m single face to one side of the main tunnel alignment and should be completed end-2000. Contractor LGU using Tamrock drillrig for drill/blast with rockbolt support and steel arches in places. Main drive should start in 2005. Visit www.alptransit.ch April 2000.  Public hearings into the 2 x 15.4 km Ceneri base tunnel will be held from 2nd April to 16th May, 2003. The main worksite will start in Sigirino where a launch cavern for each tube is planned to start tunnelling. The full lengths of both tubes will be driven with two TBMs except a section in the Valcolla area to be blasted. The alignment on the north side bifurcates from the Bellinzona-Locarno line shortly after the Giubiasco station to enter in tunnel in Vigana between Camorino and San Antonino. On the south side, connection to the existing line will be in Vezia. Around 4 millions cubic metres of spoil will be removed and recycled. The CHF2.2 billion tunnel is part of the second phase of AlpTransit. Work to commence in 2006 for opening in 2016. Visit www.alptransit.ch 14/03.CHF1.3 billion has been allocated to the 15.4 km Ceneri base tunnel, which will be constructed as two single-track tubes, fully equipped. A scheduled building in phases has been discarted because, although this would have saved CHF155 million in the short term, extra costs of CHF334 million would have been necessary later to equip the second tube. Also, a building in phases would have reduced the capacity of the tunnel by 60%. The federal department for environment, transport, energy and communication (DETEC) is expected to approve the designs in mid August. Preliminary works could start next fall and the main works in 2006-2007. The Ceneri tunnel is part of the Gotthard AlpTransit line, since its approval at a referendum vote in 1992 confirmed in 1998. The cost is estimated at CHF2 billion (1998 price).

The contract is worth CHF85 million (VAT not included) and encompasses tunnelling of the Sigirino access adit and an operating cavern. The contract has been signed slightly less than one year after the first stone of the Ceneri tunnel was laid on 2nd June, 2006 and further to 12 months of preparatory work for the Ceneri base tunnel, at Camorino and Sigirino construction sites. Tunnelling will commence next autumn and will last a bit more than two years. The 15.4 km-long Ceneri base tunnel connects Camorino with Vezia and is one of the key links of the plain line. It is scheduled to open in 2019. Read E-News Weekly 18/2003. Visit www.alptransit.ch, www.csc-sa.ch, www.frutiger.ch and www.rothpletz.ch 19/07.The contract for the construction of the Ceneri base tunnel from the northern portal, in Camerino, has been awarded to the Matro sud consortium headed by Pizzarotti teaming up with Ennio Ferrari, LGV, Cossi Costruzioni and Rodio Geotechnik. The consortium presented an offer of CHF103 million for the main northern lot consisting of a tunnel that will emerge on the Vigana hill under highway A2 where a double portal for three tracks will be constructed (two tracks for the new Alptransit railroad and one for the Locarno-Lugano line). Construction is programmed to commence on 6th October, 2008. Visit www.pizzarotti.it, www.ennio-ferrari.ch, www.lgv-sa.ch, www.cossi.com and www.rodio.chThe project will take place in three phases. First, an approach trench will be built in the slope that, from the valley, will lead to the tunnel site. Then, once the portal area is ready, some 50 metres will be excavated in soft ground just under the A2. From that point, crews will cut the rock through Mount Ceneri on an overall length of about 700 metres consisting of two tubes and a cavern system. The three large caverns, with width up to 23 m and height of 14 m, will be excavated by traditional methods. They will accommodate tracks for the south-north line, the north-south line and the Vigana connection that will be the interchange between north-south high speed lines and the local traffic. Click here for more details. Excavation will take place in soft soil using jet grouting and in rock using explosives. The supports will mainly consist of anchoring bolts, shotcrete, welded mash and steel arches. The final lining will be an inner concrete ring. Visit www.alptransit.ch 29/08.

The CPV consortium, formed by CSC SA (Lugano) and Pizzarotti SA (Bellinzona), signed the EUR43 million contract for the construction of Lot 854 at Vezia, the main lot of Ceneri Base Tunnel, including the south portal, 200 m of cut-and-cover tunnel, as well as drilling, blasting and lining both tunnels along a length of 300 m. Works at Vezia will continue until 2016. Commercial operation of the Ceneri Base Tunnel with scheduled train services is planned to start at the end of 2019. Of the total of 40.19 km of the Ceneri Base Tunnel, at the end of February 2010, 7,673 m, or 19.1%, had been excavated. Visit www.alptransit.ch, www.csc-sa.ch and www.pizzarotti.ch. 10/10.

To be driven in opposite directions from two shafts by 12.3 m-diameter Herrenknecht TBMs: one a hard rock, the other a dual-mode Mixshield slurry machine. First machine launched at Allmend Brunau shaft towards Thalwil, Sept 1998. 9.4 km long to connect with proposed Gotthard AlpTransit tunnel at Nidelbad. Contracting jv of Prader, Locher, Wayss & Freytag. Nov 1998.   Two TBMs now at work, with 12.29 m-diameter south drive machine 3 km into its 5.6 km drive having recorded a best day of 39.1 m or 23 rings while completing 673.2 m of tunnel in June, 1999. First 330 m of north drive being undertaken by second TBM in rock mode using disc cutters and conveyor belt. Following 150 m will be in slurry mode using hydraulic spoil pipelines to surface separation plant. Machine will then complete the bulk of the 2.7 km drive in rock mode in molasse. The final 700 m will be in soft mixed ground with extra drag picks on the cutterhead. Lining comprises seven bolted segments and key, 12.04 m outside diameter and 11.44 m internal diameter. Aliva pumps are used at both TBMs to pump pea gravel into the annulus. Segments are transported by converted Kiruna trucks. There are vehicle turntables behind each TBM. Zimmerberg will connect with AlpTransit Gotthard in a continuous tunnel, possibly using the same machines. Sept 1999.   South section TBM driving 5.6 km from Allmend Brunau to Nidelbad in typical Sweetwater molasse has passed the halfway point and completed 673.2 m in June, 1999 with a best day of 39.1 m or 23 rings. Conveyor capacity is 1,100 t/h using 1 m-wide belt at 2.2 m/sec. Major constraint is the rate at which spoil can be removed from site because only 13 trains/day can be handled. However, 100,000 t surface stockpile will smooth rockflow. First 330 m of 2.7 km north drive was in hard rock, then TBM was converted to slurry mode for 150 m following which it will revert to hardrock configuration. Visit www.herrenknecht.com November 1999.  Rail 2000 Thalwil junction and 900m/1,300m branch tunnels completed using drill/blast to connect with advancing cut and cover. TBM face in main tunnel left ready for AlpTransit drive to Nidelbad when finances are available. Herrenknecht TBMs completed drives in both directions from Allmend Brunau shafts and removed for storage. 27/02.
