They are deep tunnels in rock (mainly gneiss) below the groundwater level. The new tunnel is not allowed to cause sinking of the groundwater level due to existing buildings at the surface and crossing tunnels above the new tunnel. The tunnel is planned to be built by conventional driving by jumbo and explosives in full section, but alternative solutions may be accepted. To stop groundwater, mainly drilling and concrete injection is planned. To support the rock, mainly bolts and shotcrete with and without fibres will be used. Concrete formwork at the tunnel ends.

Negotiated procedure, deadline 18th February, 2002 for the construction of a double tunnel, 2.3 km for the west tube and 1.2 km for the east tube, on the northern line between Gothenburg and Norway.

NCC has been commissioned by Banverket, the Swedish railway administration, to build a tunnel in the bedrock between Oxnered and Trollhattan, western Sweden. The order is worth SEK355 million.
The assignment will involve the construction of a 3.6 km double-track bedrock tunnel and two parallel evacuation tunnels with separate exits that will have a combined length of 2 km. A total of approximately 500,000 cubic metres of rock will be blasted. The rock quality in the area is such that a portion of the excavated rock will be used as macadam for the railway tracks. The selected method is drill-and-blast. Continuous pre-injection will be conducted to reduce leakage of groundwater into the tunnel. Cement-based substances will be used for this process. Work to begin in October 2002 with an estimated construction period is about 2.5 years. Visit www.ncc.info and www.banverket.se 44/02.

The 108 sq m single-tube, twin-track running tunnel is being excavated by NCC using drill/blast on a north-south alignment in granite gneiss from four faces, using three Atlas Copco three-boom drillrigs. Full-circle cement pregrouting is being carried out from 30 off 20 m-long holes drilled ahead of each face, under the protection of which 15 m increments are advanced using Dyno emulsion. One complete cycle/week/face is being achieved. Water ingress limit of 3.5-2.5 lit/min/100 m of tunnel imposed by client Banverket. The 2.2 km-long x 27 sq m rescue tunnel is being excavated simultaneously. More from goran.manell@ncc.se or visit www.boomer-rig.com 10/04.

Banverket, the Swedish rail administration, has awarded Bergab a SEK6.1 million contract to act as chief manager for the 7.6 km Hede-Älvängen railway section on the line from Göteborg to Trollhättan (75 km) and to Norway, a project named the Väner rail line, which includes the 1.8 km Kattleberg twin track tunnel. Banverket Projektering will be the deputy chief manager for SEK5.8 million. The Vänern rail route to Norway is being expanded to a two-track railway dimensioned for speeds of up to 250 km/h. The entire route from Göteborg to Trollhättan will be completed by 2012. Visit www.bergab.se and www.banverket.se/sv/Banverket-projektering.aspx 41/08.

Halland and Scania - se/26
Railway

Negotiated contract for technical consulting to complete the 16 km Hallandsås tunnel. Work was stopped in 1997 while 5.5 km had been bored. Tunnelling planned to resume in autumn 2002 and to last 5 years. Banverket considers TBM excavation as the best option due to less water leakage but final decision to be made by the contractor that will be chosen early 2002. Whatever the method is, Banverket demands the remaining 11.5 km to be lined. Cost estimated at SKr4-4.5 billion. Visit http://ted.eur-op.eu.int, document S 218-150308 or contact Banverket, Båstad, fax +46 431 442027. Also visit www.banverket.se/hallandsas 48/01.

Cowi has signed a DKK10 million contract to supervise the TBM which will drill under high water pressures through the Halland Ridge. Cowi will also supervise the concrete segmental lining to keep the tunnel waterproof and dry. The first attempt in 1993 ended when the TBM was stopped because it had stuck in soft rock. The second attempt, using the drill/blast method, resulted in water ingress and a serious groundwater contamination by a poisonous chemical grout used to prevent water ingress. The project expects to receive environmental approval before the summer. The tunnel will cost about SEK6.5 billion. Visit www.cowi.dk and www.banverket.se 24/02.

The Swedish Rail Administration has awarded the contract to complete construction of the 8.6 km tunnel through the Hallandsås Ridge between Båstad and Förslöv to a consortium of Skanska and Vinci. The contract is valued at approximately SEK3.7 billion (€406 million). Skanska's share is 60% and Vinci's 40%. One-third of the 8.6 km tunnel has already been built.
The contract is conditional on the Swedish environmental court approving a water leakage request and a building permission from the municipality of Båstad. Skanska began work on the tunnel in 1992 but the project was stopped in 1997 after some 2,000 tons of a caulking product containing acrylic acid leaked and contaminated the groundwater. Skanska and two of its executives were found guilty of negligence by a Swedish court in January. Since 1997 however, Skanska has worked intensely to develop its environmental expertise and quality work. This has resulted in Skanska being the first international construction group to be certified in accordance with the ISO 14001 standard. Construction will be carried out using a TBM and lining with precast concrete segments, a method not used previously in Sweden. It is expected to start in spring 2003.

The inner diameter of the Hallandsas tunnel is 9.04 m and outer diameter is 10.12 m. Very varied geology, mainly gneiss but also amphibolites and dolerites. The weathering and fracturing scales are going respectively from fresh to completely weathered and from low to highly fractured. High water inflow is expected. The maximum allowed average water inflow, during 30 days, is 100 l/sec. The Skanska / Vinci JV will use an Herrenknecht hard rock TBM with two different operating modes, open and closed mode (slurry mode). The diameter of the cutting head is 10.6 m. The shield weighs 1,200 tons and is 12 m long. The back-up is 200 m long. 19,000-ton thrust available. Designed to withstand 15 bar water pressure and to excavate under 8 bar and exceptionally under 13 bar pressure. The TBM is equipped with pre-drilling equipment to do probe drilling and grouting through the shield or the cutter head. The tunnel will be lined with 54 cm-thick concrete rings consisting of eight 2.2 m-long segments. Backfilling with mortar or pea gravel. Belt conveyor working during open mode excavation and a slurry system for the closed mode operation. The TBM will be assembled within an assembly chamber, 16 m wide x 18 m high x 30 m long, to be excavated by the drill/blast method. Cross passages at every 500 m maximum, also excavated by drill/blast. There will also be a disassembly chamber at the end of the tunnel. Half way on the alignment, there is a 900 m-long access tunnel built in the nineties by the former contractor to speed up the drill/blast progress used then. This access will be used for maintenance of the TBM. The TBM is planned to start in the late summer 2005 and completion is August 2010.

Sweco Infrastructure pocketed a contract to be TBM inspector for the Hallandsås project. Visit www.swecogroup.com 38/08.

The Skanska-led consortium Skanska-Vinci HB's contract to construct the dual-track Hallandsås railway tunnel on the west coast line has been extended. Skanska's share of the increased contract amounts to SEK600 million. The customer is Banverket, the Swedish railway administration. The new contract is due to the complicated rock structure at Hallandsås, which could not be foreseen. As a result, tunnel drilling equipment is wearing more than anticipated, while progress is taking longer. Approximately 57% of the main tunnel is now constructed and Skanska-Vinci's portion of the work is expected to be completed in 2014. The Skanska-Vinci joint venture considers to have a functioning technical solution and that the project can be executed in an environmentally safe manner. Click here.
