Multidisciplinary analysis and HBIM methodology for the risk management of harmful events: the large raw earth complex of Chan Chan (Trujillo, Peru)

Chan Chan, the largest raw earth settlement in Latin America, has been on the UNESCO WHL since 1986 and on the World Heritage List in Danger since 1990. The archaeological complex is affected by a series of neg-ative natural and anthropic events that threaten the preservation of the structures and maintenance of the origi-nal historical landscape. Within the framework of the bilateral agreement CNR-CONCYTEC (Consejo Nacional de Ciencia, Tecnología y Inovación Tecnológica), the Institute of Heritage Science (ISPC) launched a collabora-tion with the Università Politecnica delle Marche, Universidad de Lima (ULima) and Universidad Privada An-tenor Orrego (UPAO), in order to provide tools (GIS, GIS3D, HBIM) for risk analysis, site vulnerability assess-ment and submission of proposals to reduce its effects. The desirable results of the project are to provide meth-odological support not only to the administrators of Chan Chan, but also to scholars and institutions dealing with raw earth heritage in various parts of the world.
