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.

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). Visit www.bav.admin.ch and www.alptransit.ch/pages/img/aktuell/Info_Ceneri_f.pdf 26/05.On 30th April, 2007, AlpTransit San Gottardo and CMC (Consorzio Monte Ceneri), a consortium whose partners are Swiss contractors CSC, Frutiger, and Rothpletz, Lienhard + Cie, signed a contract for the first underground works at the Ceneri base tunnel. 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.

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.

3.3 m pilot bore followed by 1.2 km roadheader excavation as top heading and bench. For completion end-2001. August 1998.

Three contracts awarded worth over $160 million: Teerag-Asdag/Baresel/Locher for two caverns and two shafts; Dragados/SELI for two caverns; and Taylor Woodrow/Amec/Spie Batignolles for two tunnels total length 5 km and several caverns. Completion for 2005. February 1998. Work progressing well at three projects involving six shafts, 32 caverns and 6 km of tunnels. At point 1, the larger of two new experimental halls is UX15 with a span of 35 m. The second is USA15 with a span of 23 m which will be supported by 36 anchor tendons, each with 235 t breaking strain. At point 5, the 70 m-deep shafts are being sunk through 45 m of waterbearing moraine by freezing using recirculating brine at -25 degrees C. There are also two large caverns of widths 26.5 and 18 m with 250 m of connecting tunnels. In the vicinity of point 1 the first of two 2.5 km-long, 12 sq m tunnels is under construction as part of package 3 using an Alpine Westfalia WAV 50 roadheader with 100 t/h conveyor with best day performance of 12.5 m and average of 6 m. The second tunnel will be driven using a 3.8 m-diameter TBM. The rest of package 3 work is spread throughout the 27 km-long circular LEP ring and includes 700 m of minor tunnels, two shafts and 15 chambers. Total value $220 million. The existing LEP collider will close in October, 2000 to facilitate the upgrading work and will reopen as LHC in 2005. The new ring will then carry out some of the experiments for which the ill-fated Supercollider in the U.S. and the Protvino collider in Russia had been designed. Visit the world's first website, opened in 1989 at www.cern.ch May 2000.  Spie Batignolles/Sotrabas has purchased a SM 130-C roadheader from IBS of Germany with cutting performance 150kW, machine-integral slewing belt conveyor, and attachments for rockbolting. The machine will join the two modified AM 50 roadheaders already supplied. Visit www.cern.com July 2000.
