Exploiting HBIM for Historical Mud Architecture: The Huaca Arco Iris in Chan Chan (Peru)

The construction technique of raw earth, which has always been in use most the world, left large monuments or architectural complexes to cultural heritage that need special attention due notable vulnerability material. A convenient way deal this threat, besides physical intervention, is by using an information system, such as HBIM (Heritage Building Information Modeling), a tool for damage assessment and conservation planning. This paper reports on its application archaeological setting, particular, Huaca Arco Iris, religious building old city Chan (Peru), largest monumental complex mud American continent. study part bilateral international project between Consiglio Nazionale delle Ricerche (CNR) Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica (CONCYTEC) prediction possible natural anthropogenic damages buildings mud.
