If you plan an attic extension or a reconstruction, the building authority requests the structural design as well as the check of the earthquake-resistance according to the latest codes.
The majority of buildings in Austria have not been designed for horizontal excitations of the magnitude of earthquakes. Thus their earthquake-resistance often is the crucial parameter whether the project is feasible or not. By means of adequate retrofitting measures it´s possible to optimize the costs for strengthening the structure.
For your specific project I will elaborate the check of the earthquake-resistance, the statics for the strengthening measures and the new structural elements, as well as all the required formal documents for the submission at the building authorities.
