TBF + Partner AG has been commissioned as earthing specialist for all projects in the main railway station of Bern. In this role, we check the earthing concepts of the involved contractors (including traction current, electrical, cable, fuse systems, telecom, shell construction, architecture) and bring them in line with the overarching earthing concept. For the construction phases and the final build state, we check the compliance with regard to permissible touch voltages and ensure that personnel and operational safety is guaranteed. On-site inspections are indispensable to check for the correct implementation of the earthing concept and ensure safety during the construction phases. In addition, we prepare the documentation of the built complete earthing system.
