The builders are KMW (Kombinatie Middelplaat Westerschelde), a JV of Philipp Holzmann, Wayss & Freytag, Franki, BAM Infrabouw, Heijmans and Voormolen. 'Sara' and 'Suzanna', two Herrenknecht Mixshields, 11.3 m in diameter, started from an artificial polder at Terneuzen and bored through to 20 m-deep concrete caissons at Ellewoutsdijk. The bulk of the tunnel is running at up to 60 m below sea level, making it the deepest ever to be driven. Both tubes have a concrete lining of 53,000 segments. The €726 million tunnel is open to road users since 15th March. Visit www.westerscheldetunnel.nl and www.herrenknecht.com 12/03.

Part of Betuwe line. Tubecon consortium will start construction in April, 2000 using Herrenknecht 10 m-diameter EPB for 2 x 4 km bores in clays and peaty layers. Overall length of tunnel 8 km to include 2 km-long cut-and-cover sections at each end. Slightly heavier segments than elsewhere on Betuwe line, but 8.65 m inside diameter similar to Botlek to accommodate stacked container traffic. Visit www.herrenknecht.com February 2000.

Herrenknecht advises that its 9.785 m-diameter Mixshield S-150 will be equipped with the revolutionary sonic software probing (SSP) system, a seismic forecasting process that uses sensors installed to the cutting wheel to emit soundwaves into the strata ahead of the machine and receive the reflected signals. The sensors are countersunk into the steel of the spokes and are designed to withstand pressures of up to 6 bar. The data is processed onboard by three high-performance PCs which reproduce a 3-D screen image of the ground up to 40 m ahead. The TBM is being assembled at the launch shaft and boring is scheduled to start in May, 2000. The reception shaft at Hendrik-Ido-Ambacht is still under construction.

Unity is strength. ACS, Comsa, Dragados, FCC, Ferrovial-Agromán, Hochtief, Necso, OHL, Sacyr, and Tecsa, the ten contractors appointed to drive two 25 km tunnels through granite under the Guadarrama mountain on the high speed railway between Madrid and Valladolid, joined their forces to buy four 8.5 m-diameter TBMs needed for this mammoth job. The coordinated negotiation made it possible to pay Ptas12 billion for the four machines, two Herrenknecht and two Wirth, with a 10% discount, and to cut delivery periods from 19 to 14 months. Both Herrenknecht and Wirth agreed to deliver the TBMs completely mounted, ready for tunnelling. The FCC-Ferrovial-ACS jv will receive two TBMs, one Herrenknecht and one Wirth, to excavate from the northern portals (contracts 3 and 4). The Dragados-Necso-Tecsa jv will use a Wirth TBM to drive the tunnel from one of the south portals (contract 1), while OHL, Sacyr, Comsa and Hochtief will use the second Herrenknecht TBM, from the second south portal (contract 2). The muck will be removed using a conveyor belt. It is expected excavation will start in August, 2002. Engineers estimate the TBMs will bore at an average daily speed of 25 metres or 500 metres a month. Meanwhile, FCC, Ferrovial, and ACS have started the preparatory works from the north portals on the Segovia side. The total cost for both tunnels is €179.6 million. Visit www.herrenknecht.com 50/01.

TBM progress at the Guadarrama tunnels, the greatest civil engineering project ever built in Spain, reached a milestone with a best day of 80 metres. The average daily progress is fourty metres. Benigno Blanco, the infrastructure state secretary, is confident that the 28,377 m-long twin tunnels on the Madrid-Segovia-Valladolid high speed line will be concluded towards the end of 2006 or in early 2007. Tunnelling began in mid-October 2002 in the north drive on the Segovia side. To date, progress has reached 1,800 m on the west tube and 1,500 m on the east tube, both Segovia side. On the south drives (Madrid side), the TBMs drill at the same speed so that about 6 km of tunnel has already been bored out of the 56.7 km. Breakthough is programmed in 30 months. The 9.5 m-diameter tunnels are spaced at a 25 m interval and will be connected by branches every 250 m. Up to 120 tunnellers work in four shifts of six hours. The total investment required is €1.1 billion. Visit www.wirth-europe.com and www.herrenknecht.com 14/03.
