As part of the work on the new M4 underground railway line being built in Budapest, Magyar Doka supplied the entire formwork solution for a 160 m long contract section incorporating two broadening zones and a crossing tunnel. Before commencement, Doka worked with the construction firm and the structural planner to simplify the structure and the workflow.
