What is BIN-GEO?

BIN-GEO is a computation programme to realistically calculate stresses and deformations in the subsoil. It was developed by our engineers based on our decades of experience with difficult building works.

The programme encompasses building phases, advancing and retreating states, pre-loadings and the non-linear bearing and deformation behaviour of the soil.

The material parameters required for the calculations are determined on the basis of the usual compression deformation and shear tests.

Core of the programme is a newly-developed non-linear spatial material model. Measurements of actual forces and deformations during the execution of building works have confirmed our calculations and the material model.

The BIN-GEO material model.

The newly-developed non-linear spatial material model allows us to directly understand the complex physical processes in the soil during stressing and de-stressing.

Contact elements specifically designed for foundation engineering applications capture the complicated interactions between building site layers and the components of the structure.

The detailed formulation of the tensorial stress and deformation laws was carried out in the framework of doctoral research in collaboration with the Institute for Mechanical Process Engineering at Braunschweig University of Technology.

BIN-GEO in our everyday engineering practice.

In many exacting building projects, the realistic calculation and projection of interactions between the structure and the surrounding site is of decisive importance. This applies for example to building pits on roads or adjacent to neighbouring buildings.

To solve these problems, we developed the BIN-GEO calculation programme for our everyday engineering practice. Meanwhile the deployment of BIN-GEO has proved its worth in a multiplicity of building projects. Measurements of actual forces and deformations during the execution of building works, for example at the Altenwerder harbour extension or the Europa Passage building pit, have impressively confirmed our calculations and the material model.
