It is stated that 3D recording and modelling of heritage buildings entails accurate building models (as-built). However, this paper presents an analysis of the 3D modelling accuracy for the creation of historical building information models (HBIM), considering the complexity and the deformations of historical buildings, using point cloud data and BIM tools. The 3D modelling processes analysed are based on a three-stage semi-automatic approach leading to the generation of HBIM, including manual and automatic processes. The three stages consist of: (a) optical and terrestrial laser scanning; (b) meshing processes; and finally (c) 3D solid modelling to be assembled into HBIM. Next, this approach analysed the mesh deformations generated automatically in comparison to the initial point cloud data. The deformations and the accuracy evaluation have been undertaken using different commercial software. Finally, our modelling approach shows that it can improve the accuracy of the 3D models achieved using existing BIM technologies.
Building Information Modelling (BIM) is a globally adapted methodology by government organisations and builders who conceive the integration of the organisation, planning, development and the digital construction model into a single project. In the case of a heritage building, the Historic Building Information Modelling (HBIM) approach is able to cover the comprehensive restoration of the building. In contrast to BIM applied to new buildings, HBIM can address different models which represent either periods of historical interpretation, restoration phases or records of heritage assets over time. Great efforts are currently being made to automatically reconstitute the geometry of cultural heritage elements from data acquisition techniques such as Terrestrial Laser Scanning (TLS) or Structure From Motion (SfM) into BIM (Scan-to-BIM). Hence, this work advances on the parametric modelling from remote sensing point cloud data, which is carried out under the Rhino+Grasshopper-ArchiCAD combination. This workflow enables the automatic conversion of TLS and SFM point cloud data into textured 3D meshes and thus BIM objects to be included in the HBIM project. The accuracy assessment of this workflow yields a standard deviation value of 68.28 pixels, which is lower than other author’s precision but suffices for the automatic HBIM of the case study in this research.
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 Renaissancecharacterised 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".Key words: HBIM Project, Historic Building Information Modelling, patrimonial information model, photogrammetric restitution, Architectural Archaeology, BIM. Resumen:El Modelado de Información para la Construcción (BIM) es un sistema colaborativo que actualmente está plenamente desarrollado en el diseño y la gestión de las industrias involucradas en el sector de la Arquitectura, Ingeniería y Construcción (Architecture, Engineering and Contruction-AEC). En cambio, en el ámbito de las intervenciones en el Patrimonio Cultural y Arquitectónico, son muy pocos los estudios dedicados a gestionar modelos de información. Por ello, esta investigación propone una metodología innovadora de análisis y tratamiento de la información basada en un Modelo gráfico 3D representativo de pavimentos y alicatados de un Edificio Histórico. La finalidad es crear un modelo de información gráfica que garantice la interoperabilidad de dicha información entre las diversas disciplinas que intervienen en el Proceso de Conservación y Rehabilitación Patrimonial. Para el estudio, se ha seleccionado el Cenador de Carlos V (o de la Alcoba); edificio de carácter renacentista perteneciente a los espacios exteriores del Alcázar de Sevilla, España. Este trabajo constituye un proyecto de intervención basado en un modelo de información patrimonial o del edificio histórico, denominado "Proyecto HBIM".Palabras clave: Proyecto HBIM, Historic Building Information Modelling, modelo de información patrimonial, restitución fotogramétrica, Arquelogía de la Arquitectura, BIM.
