Management of Built Heritage Via The HBIM Project: A Case Study Of Flooring And Wall Tiling

Nieto Julián, Juan Enrique; Moyano, Juan; Rico Delgado, Fernando; Antón García, Daniel

Abstract

Building Information Modelling (BIM) is a collaborative system that has been fully developed in the design and management of industries involved in Architecture, Engineering and Construction (AEC) sectors. There are, however, very few studies aimed at managing information models in the field of architectural and cultural heritage interventions. This research therefore proposes an innovative methodology of analysis and treatment of the information based on a representative 3D graphic model of the flooring and wall tiling of a historic building. The objective is to set up a model of graphic information which guarantees the interoperability of the aforementioned information amongst the diverse disciplines intervening in the conservation and restoration process. The Pavillion of Charles V, a Renaissance-characterised building located in outdoor areas of the Alcazar of Seville, Spain, was selected for the study. This work constitutes a project of intervention based on Heritage or Historic Building Information Modelling, called the “HBIM Project”.
