On the 13th of March the LBI with its partner organisation ZAMG participated on a fair concerning the restoration and conservation of historical buildings to show the potential of the specialised methods like GPR, Magnetic and 3D-Laserscanning. Target audience of the exhibition were mainly private landowners who often restore and modernise their historical properties in years of careful work. The stand of the LBI and ZAMG found great response within the audience and we were able to discuss and solve many inquiries and problems. An often discussed problem was the question of old garden structures, cellars or other hollow spaces were the LBI and ZAMG could show their expertise of knowledge within this field. The great response led to an invitation for the Exhibition 2012.
