The structure of the Technische Hilfswerk (THW) is unique worldwide, as 98 per cent of its members are volunteers, and only some two per cent are paid employees. As a federal agency, the organisation is part of the portfolio of the Federal Ministry of the Interior. The THW headquarters is in Bonn and is headed by the President of the THW, Sabine Lackner, and the Vice-President, Dierk Hansen. THW Headquarters comprises three Departments, with various Staff Units and Divisions. The full-time structure across the country is organised in eight State Associations and 66 Regional Offices.
