ITA President’s message for the ITA ITA MEMBER NATION Member Nations Activity Report 2019 Activity Reports 2019 ITA is the leading international organization for 4 Albania tunnelling and underground space. This position is dependent not only on the intensive worldwide 5 Argentina activities of the ITA itself, but also of its Member 6 Australia Nations with their leading positions in their respective countries. Over the past year, this has 9 Belarus been further consolidated via stronger communication and closer cooperation 10 Brazil between the ITA and its Member Nations, and also among the Member Nations 13 Bulgaria themselves. Issuing this print version of the yearly ITA Member Nations Activity report is one 13 Canada of the most effective ways to promote better communications within the ITA HERRENKNECHT AD 16 Chile family. By reading this report, you get the chance to better understand our Member 16 China Nations, the tunnelling projects completed, under construction or in planning in their respective countries, as well as the activities and events held or currently being 18 Colombia organized. I firmly believe that it will facilitate the furthering of cooperation among 19 Costa Rica the Member Nations and subsequently promote a better use of tunnelling and underground space, which is the mission of ITA. 20 Czech Republic I would like to thank all of the Member Nations, the ITA secretariat and Tunnelling 20 Finland Journal for making it possible! 25 France 26 Germany 28 Greece Olivier Vion 30 Hungary ITA Executive Director 31 Iceland For the 4th year, ITA in cooperation with 31 Iran Tunnelling Journal is happy to present to all of 33 Italy you the reports of its Member Nations.

ARGENTINA’S AGUA SUR In recent years, TERRATEC’s order book has demonstrated significant growth around the world. In Argentina, two 4.66m diameter TERRATEC Earth Pressure Balance Machines (EPBM) are currently being deployed by Italian contractor CMC di Ravenna on a 13.5km-long tunnel that will carry drinking water from the newly expanded General Belgrano Water Treatment Plant to the city of Lomas de Zamora.

The tunnel is a key component of the multi-billion-dollar Agua Sur system that is being built by Argentina’s national water company AySA. It is the country’s largest water infrastructure project in 40 years and will provide fresh water to 2.5 million inhabitants in the southern region of Buenos Aires.

ITA moves to digital events

In the current context of the health crisis linked to Covid19, it has become impossible to organize facetoface events. Based on this observation, the ITA had to rethink its strategy and decided to focus on the implementation of new event formats. ITA intends to maintain the social distancing measures recommended by the World Health Organization and the various governments impacted by the pandemic. To continue to maintain the link with the Tunnelling family in these troubled times, ITA will develop physical gatherings into digital events. ITA will intensify the planning of webinars and develop distance learning courses. Scheduled for the end of the year, the 6th edition of the ITA Tunnelling awards will also be held in digital format. Finally, we look forward to see you next year in Copenhagen, Denmark for the World Tunnel Congress 2021.

planning volume of inner-urban rail tunnels, mainly due to fluctuation in the awarding process. In this context, the high planned volume for the city of Munich, comprising a good 24km, is still conspicuous among the listed projects. Almost 9km of tunnels are being planned for the Hamburg Metro (partly at the pre-planning stage). Leipzig is engaged in pre- planning 7km. Further tunnelling activities involving less than 3km are foreseen in the cities of Frankfurt/Main, Nuremberg, Berlin, Düsseldorf, Stuttgart and Dortmund. n Regarding the planned volume of main-line rail tunnels, it should be noted that practically the half is accounted for by the tunnels approved for the new/upgraded Karlsruhe–Basle rail line (driven length: 19km). Further tunnels are planned in conjunction with the new/upgraded Rhine/Main–Rhine/ Neckar route (9km), the Nuremberg–Fürth rail line (7km) and the new/upgraded line Nuremberg–Marktreditz (5km). n The planned volume of projected road tunnels (106km) has again decreased slightly, due primarily to a lack of awards. On account of the German state’s revamped planning requirements, the scheduled volume has dipped considerably in recent years.

CURRENT TUNNELLING ACTIVITIES RAILWAY PROJECTS Milano – Genova High Speed Railway The project is part of the Rhine-Alpine Corridor on the trans-European transport network (TEN-T core network). The project involves the construction of two single-track tunnels, with a total length of 37km, connected by cross passages every 500m. The tunnels, which are excavated for 65% by conventional methods and 35% by TBM, are located in the complex Apennines range between Piedmont and Liguria.

CURRENT TUNNELLING ACTIVITIES Tunnelling activity in Norway has declined both in 2018 and in 2019. In 2019 we excavated 3.9Mm3 of rock. The amount of excavated rock had been steadily growing, 3 but 2018 was the first year with a decrease in volume since 2009 due to large projects being in their final phase of excavation, and new ones yet to start. Major activities are still concentrated around road and rail tunnels, with hydropower tunnels another significant contributor. In 2019, the longest and deepest subsea road tunnel in the world, The Ryfylke tunnel, was opened to traffic. Of the two other tunnels on the same project, the Ryfast will be open for traffic, but the even deeper Rogfast is delayed, although some excavation to prepare the main project has started.

The construction of eight new tunnels that, with a maximum length of 5.5km, will account for three quarters of the 8.5km of the total length of the work. The aim is to build and commission the first tunnels, those for El Risco, within 24 months of the start of the works. Mechanical means and controlled blasting will be used for the excavation. In this first phase two parallel tunnels of just over 2km each will be built with a radius of 6m and a gauge of 5m. The Aldea Tunnel is a tunnel of 3,145m length that will be the longest in the Canary Islands and will be among the 20 largest in Spain.

After completing the 42m deep access shaft LEB in 2018, the main excavation works began in January 2019. More than 800m have already been completed, mainly by road header. Thanks to a nearby tunnel connected to the shaft by a temporary gallery, all excavated material is loaded on trains underground, reducing dramatically the number of trucks in the city centre. Unexpected sulphurous gases released whilst excavating sandstone containing coal forced specific health and safety measures to be taken which significantly reduced the progress rate. The breakthrough is scheduled for summer 2020 and the tunnel will be put into service by the end of 2021.

This will also comprise 4km of twin tunnel beneath the River Thames East of London each Dudullu-Bostanci Subway Line with a diameter of around 15m. The project is currently in the planning and development phase with the procurement process for construction due to commence in late 2020. The road is due to be operational in 2027.

A303 Stonehenge Tunnel This is a proposed 11km dualling of the A303 in the vicinity of the ancient monument at Stonehenge. The works will comprise 2.9km of twin tunnels. The project is in planning and development and due for construction procurement in 2020.

Bakerloo Line Extension TfL is proposing to extend the Bakerloo line beyond Elephant & Castle to Lewisham, serving Old Kent Road and New Cross Gate. This will comprise new stations and twin 8.5km tunnels from Elephant and Castle to Lewisham. The project was released for consultation in late 2019.

Crossrail 2 This project will comprise 72km of twin-bored tunnel and 11 underground stations. It is currently undergoing a Bakerloo Line Extension review by Government prior to being taken forward to Hybrid Bill.

Coire Glas hydroelectric scheme Scottish and Southern Energy continue with plans to develop a new hydroelectric scheme in Scotland. This projects is expected to included tunnelling and large span caverns.

Haweswater Aqueduct Replacement Project United Utilities is planning to replace an existing aqueduct in the North West of England that provides drinking water for the city of Manchester. This replacement will comprise approximately 50km of 3m diameter tunnelling at depths of up to 300m.

THE ROBBINS COMPANY DEFY EXPECTATIONS

BREAKING THROUGH A YEAR AHEAD

A 5.06 m diameter Robbins Double Shield TBM exceeded all expectations at Nepal’s Bheri Babai Diversion Multipurpose Project (BBDMP). After excavating in excess of 1,000 meters per month through the notoriously difficult geology of the Himalayas, the country’s first TBM holed through nearly a year ahead of schedule.
