In the construction sector, building in existing structures is becoming increasingly important. It is particularly relevant to create new possibilities for cable routing, as significantly larger opening cross-sections are often required due to the renewal of technical building equipment. The solution for this is the beamUp in existing buildings. The beamUp can be inserted into existing beams. Large openings are created without reducing the load-bearing capacity of the existing beam. Various design variations have been developed for existing buildings which are used depending on the local conditions. When finding a solution for your conversion project, we will individually consider the local conditions.
