BIM APPLIED ON THE MEGALITHIC HERITAGE: INTRODUCTION TO THE A-BIM AND THE ASSETS OF THE MODEL FOR THE DIAGNOSTIC AND THE DEFINITION OF CONSERVATION MEASURES

Abstract. The diversity and the number of factors impacting the conservation of buildings heritage require to compare and confront a wide range of data to understand better the causes of the potential disorders. The HBIM technology and processes have already shown their ability to enhance the diagnostic of historical monuments throughout the past years and is now mature enough to be applied on megalithic heritage.

Focused on the case of the cairn of Gavrinis, this survey deals with the creation of the BIM model of the monument and its assets for the diagnostic. The 3D mapping of the disorders within the BIM model is highlighted. The pros of this workflow are also described before a short introduction to the following steps in progress.
