Methodological framework to assess military rammed-earth walls: the case of Seville city ramparts

Abstract

The high density of historic rammed earth military samples in the Iberian Peninsula is mainly due to Almoravid and Almohad presence during the 11th and 13th centuries. The aim of this paper is to provide a methodological framework that enables the assessment of these sites, using the city walls of Seville as a case study. Hence, multi-scale and multidisciplinary approaches have been developed employing methodologies based on the use of CAD GIS-BIM digital models, conceived as a Digital Cartographic Management (DCM) protocol. This research will contribute to a better knowledge of this medieval heritage that will enable the development of future intervention criteria and the creation of preventive conservation strategies. The scientific knowledge achieved will also contribute to the regulation and standardization of the restoration of monuments built with rammed earth. Conservation and repair of historic rammed earth sites should only be undertaken if there is a good understanding of the consequences of any intervention technique.
