Structural Engineering


Our strength lies in holistic solutions. With in-depth knowledge and experience in general construction, foundation engineering, building technology and construction, combined with structural design of steel and concrete frames as well as skills in geoconstruction and geotechniques, we are able to deliver high quality documents right down to manufacturing level from foundation to roof.

Our operations start from an early stage and include scheme design, program documents, contract documents, building and relationship documents.

BTB gives professional advice within building technology, building physics, strength of materials, environment and moisture/damp-proofing. BTB can also construct load-bearing components of steel.


Our competence is based on advanced calculations and calculation models. We use several programs to achieve the best results from our analyses. For normally demanding calculations we consider StruSoft’s statik and the FEM design program suitable in terms of both user-friendliness and results. We also conduct more complex analyses within structural dynamics such as, for instance, step response in floor structures and construction’s eigen frequency or shrinkage stresses in concrete constructions in Atena 3D and Etabs.

Building physics

BTB has certified passive house experts and design engineers with specialised skills in damp-related problems. We deliver energy balance calculations in line with BBR.

Steel frame and structural design of prefabricated elements

Thanks to our broad and excellent skills in structural design projects, we ensure that detailed solutions are already in place at the program stage in order to be certain that the key decisions will be the right ones from the start. We are also keen to provide our customer with follow-up throughout all design and building processes from the initial planning stage to the final inspection.


BTB began with 3D design as early as 2006 following careful evaluations of the tools available at the time.  We saw at a very early stage that both quality and the rate of production increased, and today we conduct almost all of our new building projects in 3D. In recent years increased focus has been placed on the aspect of information modelling, since our customers have become increasingly aware of what such models can deliver. The 3D model has become an information model rather than just a 3D model (the information derives from BIM which stands for Building Information Modelling.

The next step, where we try to influence the market and the customers, is to introduce the model at the administration stage, so that it is kept updated throughout the entire life of the building. We also try to bring the models out to the construction site, and this has become easier to achieve thanks to mobile units being more powerful and that the tools are now more highly developed.
