As Implenia's in-house engineering office for national and international construction projects, we cover the entire spectrum of specialist areas in civil engineering as well as foundation and special foundations. This enables us to develop project-specific innovations and special proposals, and to offer execution design together with construction services – all from a single source. Thanks to a proven network of leading planning offices, we are also able to meet exceptional capacity requirements and provide the complete range of services required in each case.
What can we do for you?
Our primary goal: design that is suitable for the construction site and the economic as well as technical optimisation of the overall results of the projects. To achieve this, we work closely with the implementing units. Our in-depth know-how ranges from tunnelling, building aids, steel construction and special foundations to bridge building.
Optimisation of construction processes with BIM
Building Information Modelling (BIM) is a central part of the digitalisation of the construction industry. We use BIM to improve our internal processes such as design, execution and operation of buildings to make them more effective. In engineering and infrastructure construction this is a particular challenge: the complex building structures, the inclusion of the surrounding terrain and different manufacturing processes make standardisation difficult. We create model-based designs for both the building geometry (formwork) and the reinforcement. The BIM models are also used for coordination with other internal units and external project participants.
We prepare structural designs mainly for the following areas tunnelling, civil engineering, bridge construction, special foundations, steel construction and hydraulic engineering and also industrial and power plant construction. Here, it is always our goal to optimise not only the building dimensions and reinforcement quantities, but also in particular the construction processes. The quantity takeoff is increasingly carried out using the BIM methodology. Together with our colleagues in the estimation and work preparation departments, we also develop bespoke solutions tailored for individual project requirements. You can also rely on our know-how when designing excavation pits (covers, retaining walls, bracing). Especially in special foundations, the influence of the chosen construction methods and the equipment technology used is particularly important. Therefore, a high degree of specialist knowledge and close networking with the construction team is required here in order to achieve results that are closely aligned with the construction site.
Design coordination/design management
We coordinate the wishes and concerns of the client, the construction site and the designer and refine them to a common denominator. Since the ideas of the different project participants often vary, we bring the appropriate tact to quickly reach the necessary decisions for the design. We are responsible for the organisation, implementation and monitoring of the entire execution design of all trades in a project. In addition, we take care of the preparation of the execution documents up to the design control and design optimisation, e.g. with regard to the construction process and building materials. In this way, we ensure that the costs remain within the set framework.
We find the right solution for technical problems: for example, we carry out feasibility studies and develop special proposals. Structural design for auxiliary construction measures is also one of our core competences – for example, for back bracing structures that enable a tunnel boring machine to start up, foundations for tower cranes or mobile cranes and storage areas for precast tunnel lining segments. Of course, we carry out all these tasks in close coordination with the team on the construction site in order to always find the ideal solution in terms of quality, costs and timing.
Immerse yourself in the world of Implenia
In the first video, join our BIM coordinator Carolin Haueis on the Varberg construction site in Sweden. In the second video, experience the construction of a new railway line through the Norwegian town of Moss. The third video shows one of the largest infrastructure projects in Europe that we are privileged to be involved in: the Grand Paris Express. Finally, in the fourth video you can see how an excavation pit is being built directly under the city centre of Berlin.

The U5 connects the large residential areas in the east of Berlin with Alexanderplatz in the centre of the city. The construction project is one of the largest transport infrastructure projects in Berlin.
We developed the segment design in close coordination with the tunnel construction management of the construction site. As the contact person on site, our planning coordinator supported the construction site and ensured that everything ran smoothly.
The New Niederfinow Ship's Hoist uses a suspended steel trough - similar to a lift - to help ships overcome the 36-metre-high terrain jump in the Havel-Oder Canal.
In constant communication with the construction site, we ensured that the extremely tight manufacturing tolerances were adhered to in this complex project.
As part of the network reinforcement of the 380 kV cable diagonal Berlin, the construction of a new underground 380 kV route is planned. Implenia is building a 6.7 km long cable tunnel with four shafts as feeder/rescue shafts for this.
Using the BIM method, we worked together with external planners and in close coordination with the client's planners as well as our work preparation and site management to develop an optimised execution plan suitable for the construction site.
The future Marienhof station of the 2nd S-Bahn main line is located in the heart of Munich, directly behind the city hall. The station structure, which is centrally located under the Marienhof, will initially be constructed in an open excavation pit, later in an excavation pit located under a concrete cover.
For this project, we provided the planning coordination for the special foundation and, in the initial phase, also for the civil engineering.
The Sandbukta-Moss-Såstad (SMS) line is part of the Bane NOR InterCity programme to develop connections between the country's main cities and relieve congestion in the capital Oslo.
In the execution phase, we are in charge of the structural design of the concrete structures (troughs and concrete tunnels in open construction) for the Kransen and Carlberg areas. We succeeded in further optimising the construction: For example, we were able to demonstrate a structure base without the prestressing originally envisaged in the client's design. This resulted in significant cost savings. We are also working with BIM on this project.
The project comprises the two-lane upgrading of the Varberg-Hamra section, which is part of the Västkustbanan railway line connecting Gothenburg with the southern Swedish city of Lund.
Within the framework of an Early Contractor Involvement contract (ECI contract), we were able to convince the client that Implenia was the right partner for the implementation of this project, particularly because of our in-house expertise in structural planning and design management. In the current execution phase, we are entrusted with the site-specific and element-based structural design (BIM) for the open construction methods.
