On Monday 15th of June we received the 1:100 scale drawings result of the detailed building survey of the Ancien Manège in Geneva. The survey was realised by ARCHEOTECH utilising a laser scanner 3D to analyse both the interior and exterior of the building. The implementation of this method allows for a very accurate survey of the complete geometry of the building. The 3D scanner is able to detect all the deformations and irregularities developed over time. This extremely valuable work represents the base from which the next stages of the project will generate from.
