Methodological and Conceptual Phases for HBIM ModellingThe Case of the Monastery of San Millán de la Cogolla de Yuso (Spain)

Resumen

The Monastery of San Millán de la Cogolla, de Yuso (La Rioja, Spain) World Heritage Site since 1997, is the result of continuous architectural interventions since the 16th century. The work presented here is part of an analysis based on HBIM modelling, which takes into account the successive phases of construction as a substantial aspect that characterizes the monuments. The interpretation begins with the study of textual and graphical documentary sources, which is developed in parallel to the three-dimensional modelling. For this purpose, tree complementary courses of action are integrated: 1) massive: related to the conceptual masses and their relationships (either known of hypothetical), 2) spatial: concerning the location, orientation and configuration of the spaces inside and around the monument, as well as the interplay with both the natural and the inhabited spaces, 3) temporal and functional: understanding the constructive evolution of the building based on historical studies, and the function and current use of the spaces at the monastery. Thus, this methodology is a valid instrument not only to manage the ongoing actions of preventive conservation but also to illustrate the hypotheses on the constructive history and to ensure a global understanding of the information associated with the monument
