MACHANG BRIDGE KOREAPlace: Masan – Changwon, SouthKorea Project: The 1.7km long bridge will join the cities of Masan and Changwon in the southern province of Gyeongsangnam-do. This will shorten the distance by 5.73km (from 16.20 km to 10.47km) and reduce the distance time by 28 minutes (from 37 min. to 7 min.) Client: Arup Detail of the Work: After the pouring of the foundation concrete for the first shell (consisting of 2,100 m3 of cement!) and installation of the second, 735-tonne, prefabricated shell, work on the Masan Bay bridge continues for Bouygues Travaux Publics. Located at the mouth of Masan Bay in South Korea, the future cable-stayed bridge will be 1,700 m long and will have the second-longest span in the country. The project involves the financing, design and construction of the bridge as well as operation and maintenance for a thirty-year period. The 450m cable-stayed main span is supported by slender 165m tall towers. The current construction highlight is that slip-forming of the western tower has finished with the construction complete up to a height of 110m. Slip-forming is the most efficient method for these more straightforward lower sections of each tower and the system is now being transferred to the eastern tower. This allows the remaining 55m section to be constructed using jump-forms which are more suited to the more complex upper tower zones which house the stay-cable anchorages. |

ISTRIAN TOLL MOTORWAY - CROATIAPlace: The distinctive Y-shaped motorway runs through the Istria peninsula and links Pula in the south of Croatia with Rijeka to the east and the border with Slovenia.Project: Istrian Motorway as described in the Review No:2 of the ‘HUKA’ is a 35-year old story connecting Rijeka and Zagreb in Croatia. Totalling to 146.50km, 90km of which are a complete motorway, 56.5km are in the profile of a semi motorway. Client: BINA ISTRA d.d Detail of the Work: The construction programme has been extensive. The first section of motorway, at 42km long, was opened to traffic in December 1999 including the Učka Tunnel, currently one of the longest tunnels in Croatia. The second section opened in June 2005 and included a further 60km of highways plus a striking, 30m tall, landmark viaduct stretching for over 1.3km across the Mirna Valley. The third and final section, at 13km long, opened in December 2006 connecting Pula with Vodnjan on the northern Adriatic peninsula of Istria. |

ROSTOCK TUNNEL - GERMANYPlace: Rostock - Northern GermanyProject: The Warnow Tunnel comprises 4km (2.5 mile) of road including an 800m tunnel beneath the Warnow River, operated with tolls. In addition to providing much needed urban congestion relief and improved access to Rostock port, the project forms part of the road network linking Hamburg to Berlin and Poland. Average daily traffic (ADT) for the first week was 7,614. The Warnow Tunnel is the first tolled road project in Germany and was opened on 12 September 2003 by Federal Transport Minister Dr. Manfred Stolpe. Client: Warnow Crossing Gmbh & Co. KG Detail of the Work: The tunnel was built using a technique known as Immersed Tube Construction: the main part of the tunnel consists of six prefabricated concrete conduits which were formed and poured in a temporary drydock nearby, floated out into the river and lowered into a dredged channel in the river bottom. This is a technique apparently pioneered in the Detroit River in construction of the Detroit-Windsor Tunnel in 1930, and replicated for sub-aqueous tunnels ever since. |

GROENE HART TUNNEL - HOLLANDPlace: Between the town of Leiderdorp and the village of Hazerswoude in the NetherlandsProject: It was decided to bore the tunnel to spare the typical peaty grasslands of the Green Heart Area. Client: HSL Zuid Detail of the Work: The tunnel consists of a single tube with a length of over 7 kilometres. Including access ramps, the tunnel length comes to 8.5 kilometres. The outside diameter of the tunnel tube is almost 15 metres. This size made the tunnel unique in the world. A concrete wall divides the tunnel in half, creating two separate ducts for the double track. The tunnel was constructed with a purpose-built boring machine (TBM) named “Aurora”. Principal Figures:

ARGE FERDEN TUNNEL - SWITZERLANDPlace: Frutigen – RaronProject: The Lötschberg Base Tunnel (LBT) is a 34.577 km (21.5 mile) long new railway tunnel cutting through the Alps of Switzerland some 400 m below the existing Lötschberg Tunnel. It is the longest land tunnel in the world, accommodating both passenger and freight trains, and running between Frutigen, Berne and Raron, Valais. Breakthrough was made in April 2005, and construction ended in 2006. Built to ease truck traffic on Swiss roads, this tunnel allows an increased number of trucks and trailers to be loaded onto trains in Germany, pass through Switzerland on rail, and be unloaded in Italy. It also cuts down travel time for German tourists heading for Swiss ski resorts and puts the Valais into commuting distance to Berne due to a travel time reduction by 50%. Client: BLS AlpTransit AG Principal Quantities :
The Ferden Site: From the logistical point of view, the intermediate working point at Ferden is the most complex construction site on the Lötschberg base tunnel. From the Schlegmatte portal – immediately adjacent to Goppenstein railway station – a 4 km long access tunnel with a 12% gradient leads down to the level of the base tunnel. The emergency station, with a complex system of rescue tubes and ventilation galleries above them, is located at the Ferden base point. In the event of an incident, the smoke and gases are extracted over the burning wagons and conveyed through the extraction system and the 300 m long Fystertellä vertical shaft to the open air. From the Ferden base point, the tunnellers excavated and constructed 2 tunnel tubes to the south and 2 tubes to the north (to Mitholz) |
