The scope of official supervision in individual projects is determined in the permit decision. Any special plans have to be presented to ensure that these plans are properly drawn up by professionals.
All work must be carried out under the supervision of qualified supervisors. Reviews, inspections and inspection documents are used to ensure that the workers follow the orders and that building work is performed in accordance with all regulations, orders and the permit decision, so that good-quality results can be achieved. When a building project is started, the general rule is that a start-up meeting should be organised for the various people involved.
