Tunnelling & Underground

At SYSTRA Italy, we specialise in the design of tunnels and underground structures. Dense surface environments, topographical challenges, and limited space are making underground solutions increasingly attractive, especially in urban areas. We have extensive experience designing and constructing urban tunnels in complicated geological contexts and congested areas.

Railways

Our offices conceive innovative and reliable solutions for the most widely used rail transportation systems. Our expertise in Conventional Rail Links, High-Speed Lines (HSL), covers alignment and general design, structural and geotechnical design of civil works, trackworks, signalling, earthworks and drainage, MEPs, environmental criteria.

Urban Mobility

Our offices develop cutting-edge and dependable solutions for urban mobility, including Bus Rapid Transit (BRT) and rail transportation systems. Our expertise spans Conventional Rail Links, High-Speed Lines (HSL), Light Rail Transit (LRT), and BRT, covering alignment and general design, structural and geotechnical design of civil works, trackworks, signalling, earthworks and drainage, MEPs, and environmental criteria.

Roads

We manage a wide variety of projects, from the simplest to the most complex highway and road interchanges. Our expertise covers different technical areas such as alignment and general design, structural and geotechnical design of civil works, roadworks, earthworks and drainage, MEPs, environmental criteria.

Bridges

At SYSTRA Italy, we develop every type of bridge, from the simplest continuous viaduct to complex suspension and cable-stayed bridges. Our expertise not only covers the design of new bridges but also the structural rehabilitation of ancient and historical bridges made of concrete, steel, and masonry. Our services encompass all design stages, from concept design to on-site assistance, including geotechnical, structural, and architectural studies.

Buildings

Our engineers have technical competence and functional sensitivity to help our clients shape their ambitious projects. Our expertise covers many different technical areas such as structural design, retrofitting, fire engineering, seismic engineering, performance-based design, MEPs, robustness analysis.

Our construction management services encompass planning, monitoring, and risk assessment. We ensure construction projects progress smoothly, maintaining high safety and quality standards throughout the process.

Value Engineering

Our value engineering services focus on project optimisation through new technologies and advanced FE simulations. We ensure cost-effective, innovative solutions that enhance project performance and efficiency.

MEP Design

We specialise in MEP design services, covering complete safety system design, ventilation and fire safety, CFD simulation, and ventilation strategies. Our commissioning support ensures optimal system performance from the outset.

BIM Modelling

We offer comprehensive BIM modelling services for civil works, roads, landscapes, finishes, and MEPs. Our BIM implementation enhances project accuracy and efficiency, supporting better planning and execution.

Tender Assistance

We provide tender assistance with communication strategies, professional graphic support, schematics, renderings, and illustrative videos. Our services help present project proposals effectively, increasing the chances of success.

Independent Check

We offer independent checks for code compliance, technical content accuracy, and project buildability. Our assessments ensure projects are ready and feasible, providing reliable validation and peace of mind.

Innovation

Tunnel Tech

Thanks to 40 years of experience in the field of underground structures, SYSTRA Italy developed advanced skills in providing innovative solutions for tunnel design and construction, supporting its clients in adding value to their challenging projects.

SSS.infra

SSS.infra is a rigorous design Guideline developed and patented by SYSTRA Italy for the quantitative multicriteria performance assessment of sustainable infrastructure and for the retrofitting of the existing transportation network.

More

i.BIM

i.BIM represents the way SYSTRA Italy goes beyond the current limits of Building Information Modelling, providing customised workflows and post-processing tools aimed at making infrastructure projects more reliable, productive and profitable.

Reducing environmental impact and avoiding traffic disruption during construction

The Follo Line Project is a new railway line between Oslo Central Station and the public transport hub at new Ski station (20km long twin tunnels). The concrete tunnel will be connected to both existing constructions at Oslo Central station and to the long tunnel, the longest railway tunnel to date in the Nordic countries.

The Drill & Blast contract includes the construction of several tunnels built in Ekebergåsen (1.3km), a hill formed by gneiss of the Precambrian period with presence of alum shale, located east of the Oslo fjord. The tunnel (design and construction) has a lot of challenges due to the presence of existing tunnels (raw water tunnel and escape tunnels) and oil deposits (watertight section).

The Oslo S contract includes the construction of a cut and cover tunnel from 6 to 2 tubes (625m) and 4 technical buildings. The cut and cover area is characterised with severe geotechnical condition – quick clay – that required the use of ground improvement (jet grouting).
