Civil engineering & infrastructure at PORR

The basis for modern cooperation

Railway construction brings together an array of different construction services: earthworks and road construction, bridge construction and laying tracks, as well as building construction for railway stations and other structures.

The synergies between these divergent fields are what makes railway construction one of PORR’s core competencies. We draw on decades of experience in demanding projects at home and abroad and provide all trades needed to realise a railway project from a single source. Our own equipment pool and interests held in other railway construction equipment companies guarantees us access to all of the specialist tools needed for building track superstructures and we also hold all requisite permits (railway licence and ECM certification). In addition, our comprehensive expertise in railway construction allows us to operate construction sites in areas where traffic and transport is still running – with customised and safe solutions.

As a specialist in realising large-scale infrastructure projects involving multiple services, PORR handles complex challenges by applying its comprehensive expertise.

Structural engineering includes, for example, bridges, passageways, subways, tunnels using the cut-and-cover or boring method, earthworks, and engineering structures. Structural engineering also includes traffic routes and everyday infrastructure such as flood barriers, underground railway construction, underground car parks and parking decks.

Bridge construction is still considered the supreme discipline today. We support our customers with the utmost professionalism and precision as a reliable partner throughout all phases of a bridge's life cycle – from planning and construction to maintenance.

We can look back on more than 100 years of tradition in bridge construction and have extensive expertise – not only in new construction, but also in the renovation of existing bridges. PORR's range of services extends from steel and prestressed concrete bridges of all kinds to steel composite and steel bridges, cable-stayed bridges and precast bridges. Whether it's carrying out foundation work in rivers or handling large renovation projects in inner-city road networks with high traffic volumes, we use the experience of our experts and the latest technology to implement complex projects successfully and in an environmentally friendly manner. Most of the materials obtained from demolition or excavation during construction are then professionally processed and returned to the material cycle.

PORR SUISSE AG has a working group of specialists in the field of rock technology.

Whether it’s rock clearance, rock stabilisation, various anchor works, nail walls, slope stabilisation, avalanche protection, ice clearance or repairs and installation of rockfall protection systems. With our experienced team, we meet the most demanding requirements for reliability, flexibility and versatility, giving us the ability to carry out instant work of any type.

From small power plants to flood protection structures: As a leading provider in hydraulic engineering, PORR is involved in a wide range of projects in power plant construction, protective hydraulic engineering and dam construction both at home and abroad.

Hydraulic engineering combines a wide variety of civil engineering disciplines. From underground waterproofing, special civil engineering, tunnel construction, earthworks, concrete and road construction to landscape gardening – PORR can carry out the entire range of services with its own specialist staff.

Every construction project needs a solid foundation – precisely tailored to the respective soil conditions and the planned purpose. Larger construction projects or infrastructure projects are especially in need of specialised solutions. As a full-service provider in special civil engineering, PORR carries out all types of excavation support, slope stabilisation, deep foundations, cut-off walls for flood protection projects, and soil improvements.

We offer all common state-of-the-art solutions and cover the entire spectrum of special civil engineering – from diaphragm walls, sheet pile walls or narrow walls through to solidification, injection sealing and elevation grouting.

PORR’s special civil engineering is characterised above all by the fact that it is unique on the market: for every construction project, we offer a complete, customised solution that takes into account the most diverse customer requirements. Everything is possible, from the execution of classic subcontractor services to “turnkey excavation”. This type of full-service provision enables our clients to reduce interfaces and achieve greater certainty in terms of planning and costs from the moment the contract is awarded.

PORR has long been a trailblazer in road construction and infrastructure. As early as the start of the 20th century, PORR played a key role in the construction of Vienna’s Ringstraße as well as in the Grossglockner High Alpine Road in 1930. We build on this extensive experience in every one of our projects. Far beyond Austria, Germany, Switzerland, Poland and the Czech Republic, PORR is now a leader in building transport infrastructure.

From complex large-scale projects and transport infrastructure projects like the construction of motorways, expressways and railways, to small-scale projects such as asphalting pavements and parking areas, we deliver the entire range of transport infrastructure construction with the utmost professionalism.

Here we provide the entire range of road construction services from a single source – from earthworks and unbound base courses to asphalt or concrete road surfaces, including drainage work. With our modern equipment and highly trained specialist staff, we are ideally equipped to meet every requirement.

Road construction of the future is sustainable and conserves resources. The majority of the building materials used are recycled and reused. State-of-the-art asphalt mix plants guarantee the careful use of energy and resources. Advances made in applying digitalisation to road construction ensure effective and cost-saving asphalt paving through cutting-edge software solutions that are constantly evolving.

Underground constructions such as tunnels, shafts and caverns create infrastructure that is fit for the future – one of the most demanding civil engineering disciplines, which also happens to be one of PORR’s core competencies. Our tunnelling teams can look back on extensive experience and references from the successful completion of tunnel projects for roads, railways, district heating supply, sewage systems and pumped storage power plants. The repair and modernisation of existing tunnels complements our services in our home markets. Expertise, innovative, flexibility and an ability to find technical solutions are an absolute must in underground construction. Every metre excavated can reveal an unforeseeable challenge, which PORR manages professionally and expertly, with safety as the top priority.

From building underground railways in inner-city conditions, conventional tunnelling with shotcrete to highly sophisticated tunnelling with tunnel boring machines: PORR is one of Europe’s leading providers in all areas of underground construction and solves complex challenges with expertise and innovation. A clear focus on lean structures and processes – coupled with the consistent use of digital tools and energy-efficient production equipment – form the basis for cost-effective and innovative project management. As a reliable partner, we have successfully proven our technological expertise in all common tunnelling methods time and again (Gripper-TBM, open-shield, earth-pressure and hydro-shield) and also in large cross-sections from six to 13 metres.

Water is one of the most precious resources on this earth – and a conscientious approach is a prerequisite for guaranteeing our quality of life in the longer term. Hydraulic engineering encompasses hydropower engineering, river engineering, coastal engineering, navigable waterway construction, flood protection and groundwater remediation.

Another essential factor alongside pure civil engineering skill is the assessment of the ecological impact of hydraulic engineering projects. From small power plants to flood control structures: as a leading provider of hydraulic engineering services, PORR is involved in a wide range of projects in power plant construction, flood protection, and dam construction at home and abroad. Hydraulic engineering combines a wide range of construction disciplines. From subsoil sealing, special civil engineering, gallery construction, earthworks, concrete and road construction to landscaping – PORR delivers the full range of services with its own specialist staff.

Whether electricity, gas, water, wastewater, telecommunications or district heating pipelines – a close-knit network of pipelines provides the basis for our modern lifestyle and keeps us supplied with the essentials, day in, day out.

This is why pipeline construction is a key component of our service range. Our team of experts builds pipelines for supply, disposal and communication using state-of-the-art technologies.
