About the construction

A complex of office buildings located at the corner of Chmielna Street and Jana Pawła II Avenue in the centre of Warsaw, developed by HB Reavis. Varso Tower is the tallest building in Poland and the European Union, with a total height of 310 metres. The building includes a five-storey underground garage and is adjacent to the cross-city tunnel. 

Client benefits

For this project, we drilled the deepest borehole for a building project in Poland, with a depth of 75 metres below the ground level. Also, we carried out the most advanced laboratory tests to assess strength and deformation parameters, field tests of all types, as well as foundation excavations to a depth of more than 10 metres.


“Geotest carried out comprehensive tests of subsoil for the Varso complex we are developing. Geological analyses and environmental site assessments were performed to the highest standard, taking into account the issues arising from the implementation of a project on a European scale.”

The biggest challenge of the project was the need to perform deep drilling and probing in a difficult urban area, in the ground with numerous underground obstacles. An important aspect of the work was also the need to fit into the tight work schedules of the client and other teams operating on the same construction site.
