Consulting and planning
Special civil engineering planning.
Customised concepts for safe and economical solutions.
Tailored to the requirements of your project, our own specialist engineers work with you to develop an optimised construction pit and foundation concept. This ensures that your customised structure can be built economically and sustainably.
As an engineering office for planning in the entire field of specialised civil engineering, we have been operating successfully for many years. And not only throughout Germany. Customers also like to rely on our expertise internationally.
As a service-orientated company, we are your competent partner for all questions relating to your construction project. With us, you receive personalised consultation, planning, construction and implementation from a single source.
Contact persons.
Building is a people business. This makes personal contact all the more important. Here you will find your contact persons for PORR Specialised Civil Engineering- Planing in Germany.
Construction pits.Detailed and reliable planning.
At PORR Spezialtiefbau Planung GmbH, we rely on the expertise and many years of experience of our employees. With the additional support of 3D planning and Building Information Modelling (BIM), we define an economical and safe solution for your construction project in advance. An important basis for a smooth construction process within the specified time frame.
Our services in detail:
- Planning the construction pits as well as the necessary safety measures for the neighbouring buildings
- Planning the dewatering measures
- Preparation of logistics plans with detailed consideration of the characteristics of the large equipment
- Coordination of the construction processes with the approval authorities
- Drawing up framework and detailed schedules
- Preparation of the design, approval and execution planning
Deep foundations.Sustainable solutions in depth.
Deep foundations - often referred to as pile foundations - are always used where the layers close to the surface do not adequately support the loads of the structure and the building loads have to be transferred to deeper, more load-bearing soil layers. Here we plan for you with all common pile systems, for a foundation that is optimally tailored to the requirements of your project.
Subsoil improvements.Stable subsoil for every project.
In the case of very soft or less load-bearing layers, targeted subsoil improvement measures can be an economical alternative. In this area, we offer a wide range of traditional and innovative techniques for stabilising the existing subsoil. The expense and cost-effectiveness of a stabilisation measure always depend heavily on the local boundary conditions.
The following methods are frequently used:
- Soil mixing methods
- In-situ concrete columns
- Gravel tamping columns
- Vibro-compaction
- Vibro replacement
Whether deep foundations or subsoil improvement - the decisive factor is a safe and economically optimised solution. Through the targeted combination of different systems, we increase cost-effectiveness and ensure a smooth process on the construction site.
Our services in detail.
- Assessment and evaluation of the subsoil and supporting structure with regard to foundation requirements
- Determination of the most suitable foundation variant for your project
- Optimisation of the foundation design and foundation geometry
- Preparation of the design, approval and implementation planning
Securing and refurbishing.We create a secure and stable foundation.
Securing neighbouring buildings with deeper construction pits.
If a deeper working level is planned next to or near an existing building, underpinning is often required to prevent the building from slipping into the construction pit. Underpinning may also be necessary if a building is to be subsequently deepened to prevent cracking due to soil settlement.
The foundation loads of the existing building with a shallow foundation can be transferred to a deeper foundation level using so-called underpinning bodies. Underpinning can also help to increase the external load-bearing capacity of existing foundations as well as to repair damage due to increased impacts, e.g. as a result of a change of use of the building.
Retrofitting foundations for existing buildings and increasing the load-bearing capacity.
Is there major subsidence in an existing building? Or do larger loads have to be transferred to the subsoil as a result of a planned conversion or a subsequent addition to the building?
In this case, retrofitting foundations of the existing building to a deeper foundation level are often necessary to ensure that the building remains stable. Through the targeted use of micro piles or the injection of ultra-fine cement, for example, subsequent foundation work can also be carried out in the building and often even during ongoing operations.

Solutions from a single source.Safe and economical.
PORR is a technology leader in the planning and construction of sophisticated, customised customer requirements – safe and economical.
We use our extensive expertise to implement tailor-made solutions. We have our own teams of experts in all key trades along the entire construction value chain and offer comprehensive specialist knowledge from a single source: in government services, building construction, industrial construction, structural engineering, mineral raw materials, special civil engineering, tunnelling, environmental engineering and transport route engineering. Our service portfolio ranges from general planning to final implementation.
Our expertise – your benefit:
Holistic planning and execution
Smooth, punctual, accident-free and high-quality completion of your projects is essential for us. We offer all planning and construction services from a single source, from the execution of individual trades to cross-trade solutions including planning, site manager, delivery and installation of all materials.
Construction management: safe and economical
Cost-effectiveness and safety are at the centre of our solid construction management. Consistent, harmonised construction processes, transparency and the stringent implementation of measures for deadline and quality assurance are a matter of course for us.
Certified safety
We set the highest standards in terms of safety and quality. Our solutions guarantee reliable realisation and are confirmed by all the necessary test certificates .
Perfect project management
With sophisticated and proven digital control processes for the planning and execution phase, we ensure cost-effectiveness and safety in construction. Lean management methods help us to monitor and optimise construction progress on a daily basis so that all trades work together smoothly.
Optimised logistics and execution
Thanks to our own employees and the PORR network, we ensure optimal construction site logistics, punctual material deliveries as well as the organisation and execution of all necessary trades. Our promise: Construction from a single source.
Active deadline controlling and quality assurance
It is crucial for clients to be informed about the status of their project at all times. Regular budget and quality checks as well as an overview of schedule adjustments are essential. With our construction status report, you are always up to date.
Short runtimes
Thanks to our synchronised construction process and our many years of experience, we coordinate all work processes efficiently. Our experienced engineers simulate the construction process right at the start of a project, identify potential weak points and optimise the workflow.
Certificates/Approvals.
Ensuring quality requirements are met is a top priority at PORR. This is also demonstrated by our certificates and approvals. To ensure we are always up to date, our certificates and approvals are regularly reviewed and renewed by external audits and independent certification bodies.
