2 INNOVATION IN UNDERGROUND SOLUTIONS

Infrastructure specialists, since 1982 MAIN TUNNELLING PROJECTS  Engineering provides specialistengineering, project management and riskmanagement services for infrastructureconstruction. For more than thirty years, we have beenhelping clients build works that form theinfrastructural backbone of local communities.We are committed to service quality andon-time delivery and are firmly convinced ofthe importance of designing and building workswith a sustainable economic, environmentaland social footprint. We have operations in Italy, Turkey andCanada to deliver the best possible services forour key markets, Europe, the Middle East andNorth America. 3

INNOVATION IN UNDERGROUND SOLUTIONS Robust operating knowhow We offer solid project engineering and management expertise in tunnel construction for overground and underground railways, motorways, service infrastructures for the mining and oil & gas industries. Our proprietary “smart tunnelling” platform minimizes sovrastructural risk. We successfully apply our in-depth knowledge of the BIM process (Building Information Modeling) during both design and construction, with significant benefits for our clients. Our modeling, risk management and risk assessment services provide effective support for construction of roads, railways, bridges and dams. As a company in the   Group, we are backed by the modeling and simulation knowhow of our sister-company EnginSoft to resolve operational questions and problems relating to statics and fluid dynamics for excavation and construction work. 4

An innate vocation for partnershipWe believe in the power of collaboration. MAIN TUNNELLING PROJECTSMany of our projects are conducted throughconsortia and joint ventures to provide the endclient with top competences in the variousdisciplines. We work side by side with generalcontractors, other engineering and designcompanies, and consultants in geotechnics,finance, environmental and socio-economicservices. We are loyal, reliable partners, whounderstand the effectiveness of teamwork.

5 A14 HighwayINNOVATION IN UNDERGROUND SOLUTIONS The world’s first project to widen a highway tunnel Country in the presence of traffic, without resorting to Italy alternative routes or reducing the level of service, was executed in the early 2000s, on the Nazzano Owner Tunnel on the A1 Highway, near Rome, Italy. Given Autostrade the success of this first project, Autostrade per per l’Italia Spa l’Italia Spa decided to use the same method to widen the Montedomini Tunnel, as part of the Client project to modernize the A14 Bologna-Taranto Ghella Spa Highway with construction of a third lane plus an emergency lane in the section between Ancona Period North and Ancona South. 2010-2011 For the Montedomini Tunnel project, Activities performed SWS Engineering used the innovative pre-cut Final and detailed technique, where excavation work is performed design, assistance for “around” a pre-installed protection shield for road construction works traffic, enabling the tunnel to remain in service during construction operations. Special attention was paid to minimizing risk, for example by avoiding distractions for drivers and protecting site workers against exposure to exhaust fumes from passing traffic.

8 HSR Underground Link in FlorenceINNOVATION IN UNDERGROUND SOLUTIONS The high-speed underground rail link in the city of Country Florence is part of the high-speed railway between Italy Milan and Naples, in Italy. Owner Two single-track tunnels of about 6.5 km each Italferr Spa link the southern end (Campo di Marte) and the northern end (Rifredi). A cover between 5 and 27 m Client separates the tunnels from the existing urban Consorzio Nodavia (RE) structures. Period The excavation was performed with an EPB 2009 tunnel-boring machine to balance the stresses of the excavated ground. The machine diameter Activities performed was 9.4 m. Detailed design for general contractor, The excavation work below the densely monitoring constructed and populated city of Florence was of construction works subject to a high risk of subsidence. The underground works were designed to ensure the serviceability of the existing infrastructures and buildings. Subsidence models were developed to estimate the effects of excavation on buildings, railway lines and city monuments. Innovative consolidation technologies such as “compensation grouting” were implemented to contrast the subsidence risk. SWS also provided a safety monitoring service for infrastructures affected by excavation during construction work.18

10 MAIN TUNNELLING PROJECTSOrte-FalconaraRailway Line Country Italy Client Torno Internazionale Spa Period 2004-2006 Activities performed Detailed design and safety coordination of worksSWS Engineering provided design and constructionsupport services on a project to double a sectionof nearly 5 km of the existing single-track railwaybetween Orte and Falconara, two towns in centralItaly. In providing these services, we handled designand construction-related problems for the Fabrianotunnel, bridges, viaducts, box culverts, under/overpasses, railway superstructure, electrification,signaling and telecommunication systems. During the construction period, we providedconsultancy services and were closely involved inplanning the railway doubling works, which werecompleted without disruption to services on theexisting line. We performed the following activities:→ widening the line, in part through a second trackand in part through creation of a new route;→ removal of all existing level crossings;→ realization/adaptation of road crossings;→ adaptation of stations and halts;→ renovation and technological improvements,with the realization of electric traction lines,signaling and network circulation safety systemsand railway telecommunications. 21

INNOVATION IN UNDERGROUND SOLUTIONS International awards and care for the environment Engineering won the “Technical innovation of the year” award at the International Tunnelling Awards in Toronto (Canada) in 2012. Our winning project investigated how expanded clay can be successfully employed as a back-filler in deep mechanized tunnelling. At subsequent editions of the Awards, we have always been among the finalists. Our project for the 2014 Awards was the Smart Cross Passage (SCP), for which a patent application is currently pending. We also support a strong safety culture and principles of sustainability in all our operations, and we are a charter member of the Green Building Council promoting LEED (Leadership in Energy and Environmental Design) in Italy. 22
