Major Project of the Year (over €500M)

Eurasia Tunnel Project

The Eurasia Tunnel Project (Istanbul Strait Road Tube Crossing Project) will connect the Asian and European sides via a highway tunnel going underneath the Bosphorus. The project is being constructed by a Joint Venture (YMSK-JV) formed under the leadership of Turkish firm Yapı Merkezi and South Korean firm SK E&C. 5.4 kilometers of the project will comprise a twostory tunnel to be constructed underneath the seabed using special technology To successfully deal with the complex challenges at the Istanbul Strait Road Tube Crossing Project, the 13.7m Mixshield from Herrenknecht was designed exclusively for the construction joint venture and included a number of specially developed features such as 19’ disc cutters with internal pressure compensation device or a hyperbaric transfer shuttle Specifically innovated, developed and designed seismic joints that can resist under 12 bar pressure were installed to accommodate differential displacements at proper locations at the transition zones between rock and soft soils.

Tunnelling Project of the Year (between €50M and €500M)

1st Phase of Low and Intermediate Level Radioactive Waste Disposal Facility Construction

The chosen site can hold 800,000 drums (160,000m3) of LILW. In this project, which is the 1st Phase of LILW Disposal Facility Construction, a disposal facility was constructed to store 100,000 drums (20,000m3) of LILW. A disposal facility consists of six silos storing LILW and a 3.9km access tunnel. For the geometrical shape of silos, the shape of a dome and a cylinder was chosen to ensure both the mechanical stability and the maximum storage space with less excavation. Such deep underground space for a disposal facility of LILW was constructed solely in Finland and Sweden where geotechnical condition is relatively good compared to Korea’s. It is believed that the technology acquired from the construction of a disposal facility for radioactive waste will be a good example of the construction of a disposal facility for 98 nuclear plants located in Korea, China, and Japan.

Outstanding Project of the Year (up to €50M)

Norsborg Metro Depot

The Norsborg Metro Depot is an important part of the development of the Stockholm metro system. The depot will provide storage, train wash and service areas for 17 trains and will also be a working place for 100 employees. The depot is located underground in hard rock. It consists of three rock caverns, 300 by 24 meters each, connecting tunnels and areas for technical equipment. Conventional drill and blast method with top modern equipment was used. The total rock volume is 320 000 cubic meters and the total length of the tunnels and caverns is 3000 meter. The scope of the project led to the division into two contracts:
  • one consisting in the excavation and the waterproofing of the tunnels and caverns
  • one consisting of the buildings, installations and the tracks.
Between 2013-2015 Skanska excavated the tunnels and caverns that will serve as storage for the metro depot. The complete depot is to be finished in 2017.

Technical Innovation of the Year

Innovative Vehicle-mounted GPR Technique for Fast and Efficient Monitoring of Tunnel Lining Structure Conditions

A noncontact nondestructive testing technique in the field of operation tunnel health status evaluation, whose air-launched antennas can detect linings and surrounding rock conditions at 0.9~2.25m distance between the antenna away from the tunnel walls. We have completed the inspection of 91 tunnels with a total 122 km by Railway vehicle-mounted GPR technique. The test tunnels are located in the Baoji-Zhongwei line, Xiangfan-Chongqing line under the jurisdiction of Xi’an Railway Bureau. Just as the old line of Xiangfan-Chongqing line, where the tunnels approaching to the design life, aging problem is particularly prominent Railway vehicle-mounted GPR technique for tunnel detection can detect the tunnel linings of national railway network and complete the tunnel defect census in a short time. This technique solves the major problems on national railway network tunnel safety inspection and has obvious social benefits.

Environmental Initiative of the Year

The Corrib Tunnel Project - tunnelling in environmentally sensitive area

Construction of 4.9km TBM tunnel incl. the fit-out with a gas pipeline and the backfilling of the tunnel. The client SEPIL decided to install the 20’ gas pipeline with all its relevant accessory components in this sensitive nature reserve in a tunnel. The tunnel was to be driven
in advance by mechanized means with the residual tunnel cross-section subsequently being backfilled. The final alignment of the onshore pipeline section was the result of an intensive
development process with the aim to minimise and mitigate the potential for impact of the proposed route on the receiving environment. The key criterion in the identification of the modified route, underpassing the Sruwaddacon Bay between Glengad and Aughoose, was the trenchless underground construction of a 4.9 km long section due to the environmental impact of its location.

Safety Initiative of the Year

MineARC Systems Compressed Air Management Solution

Emergency refuge forms an integral part of a tunnelling project’s wider Emergency Response Plan (ERP). In an emergency situation (such as a tunnel fire), when evacuation is no-longer safe or practical, a refuge chamber is designed to provide a safe and secure ‘go-to’ area for personnel to gather and await extraction. In looking for a solution to the ITA Guideline’s requirement for the use of compressed air and to maintain positive pressure to refuge chambers to avoid ingress of toxins, MineARC’s engineering team developed a breathable air system that is unique to the market; offering a range of new features aimed at reducing running costs and improving operational safety during an emergency. This system is called the Compressed Air Management System or CAMS.

Innovative Use of Underground Space

Toledo Metro Station on Line 1 in Naples

The Toledo Station is a unique example of a decentralised museum, offering dynamic fruition of the artists’ creations, as the citizens have the possibility to travel an open artistic itinerary. Building the station has involved the re-systemisation of the surrounding urban context. In fact, the underground works include a long pedestrian passageway starting from the service tunnel, and linking the pedestrian platforms to the secondary exit in Piazzetta Montecalvario, a square that has been regenerated and re-qualified with positive effects for the surrounding Spanish Quarters (built in the sixteenth century under the Spanish Viceroy). In addition to the underground works, part of the Via Diaz above the main shaft, has now become a broad pedestrian square. Trees were planted in the narrow area whilst along the southern perimeter, parasols have been arranged to protect the street stalls that were formerly scattered over the pavement in Vesuvian basalt, lending grace and comfort to the area.
