All types of structural calculations
From load-bearing walls and roof structures to foundations, connections and specialist checks. View ten categories with explanation and preparation.
Find the calculation for your construction question
This overview contains 91 topics in ten categories. Choose a construction project, construction material or technical control. Topics can come together within one assignment: for example, an extension also includes foundations, beams and connections.
For existing services you will find a link to the project page with preparation and price information. The other topics explain what an assessment entails and what data may be required.
Breakthroughs and existing homes
In the event of a breakthrough, the route along which loads are transferred to the foundation changes. The assessment therefore looks beyond the new beam: the supports, remaining walls and construction underneath also count.
8 topicsExtensions and outbuildings
An extension adds new loads and often connects to an existing facade. The roof, supporting structure and foundation together form the design. The connection with the main building deserves attention, even when the outbuilding is small.
9 topicsRoofs and roof extensions
A roof calculation can concern the load-bearing beams, but also a new opening, extra weight or another use. In the case of a roof structure, the load must also be able to be transferred through the existing home to the foundation.
10 topicsFloors, stairs and balconies
For floors, both load-bearing capacity and usability count. A floor that is sufficiently strong can still bend too much or vibrate annoyingly. Openings, heavier use and new supports change the principles.
10 topicsFoundations and earth retaining structures
The foundation connects the structure to the ground. Structural calculations and geotechnical investigations must therefore be based on the same loads, heights and soil data. Groundwater and the environment also play a role in soil retaining.
10 topicsComplete buildings and transformations
In a complete building, the relationship between the roof, floors, walls, columns and foundation is designed. The use, layout and construction method together determine the calculation principles. Transformation involves an assessment of the existing situation.
10 topicsCalculations per construction material
The material determines how a part absorbs forces and deforms. The same span does not automatically lead to the same solution with wood, steel or concrete. Connections, sustainability, fire and the chosen construction method are part of the consideration.
6 topicsConnections and fixings
The forces in a structure must be able to be transferred from one part to the next. A connection is therefore assessed together with the connected materials and the substrate. The number of bolts or anchors alone does not say enough.
8 topicsTechnical checks within a calculation
A structural calculation usually consists of several checks. Which checks are required depends on the structure, material, use and the relevant loads. These topics are therefore not automatically ten separate assignments.
10 topicsTemporary, industrial and civil constructions
These specialist topics require experience with the relevant construction type and the use or implementation situation. This overview helps to formulate a question. Discuss in advance which expert can carry out the design, assessment and coordination.
10 topicsCalculation, research or drawing?

What information do you send?
- Describe the current use and desired change.
- Collect available drawings, calculations and photos.
- Indicate unknown data and desired implementation date.
- Agree which parts, studies and drawings the assignment includes.
A knowledge subject is not a standard package. For specialist projects, it is discussed in advance which expertise and executive party are required.
