Abstract

Multidisciplinary data integration within an information system is considered a key point for rehabilitation projects. Information regarding the state of preservation and/or decision making, for sustainable restoration is prerequisite. In addition, achieving structural integrity of a historic building, especially one that has undergone many construction phases and restoration interventions, is a very elaborate task and should, therefore, involve the study of multidisciplinary information regarding historical, architectural, building material and geometric data. In this paper the elaboration of such data within 2D and 3D information systems is described. Through the process described herein, a methodology, including the acquisition, classification and management of various multisensory data, is displayed and applied within a geographic information system (GIS). Moreover, the multidisciplinary documentation process, aggregated with the surveying products, generates 3D heritage building information modeling (HBIM), including information regarding construction phases, pathology and current state of preservation of a building. The assessment of the applied methodology is performed concluding in a qualitative and a quantitative manner, in both 2D and 3D environments, providing information to facilitate the structural assessment of a historic building. Thus, in this work, the described methodology is presented, combining the multidisciplinary data with the development of GIS thematic maps and an HBIM. Representative results of the suggested methodology applied on the historic building of Villa Klonaridi, Athens, Greece are displayed.

Highlights

In the field of monument protection, a growing need has emerged for the documentation and visualization of built cultural heritage assets and in relation to their pathology
The first step was the creation of a 3D model of the historic building, using the data provided from the geometric documentation, in order to acquire the volumetric information of the building

Summary

Introduction

In the field of monument protection, a growing need has emerged for the documentation and visualization of built cultural heritage assets and in relation to their pathology. Over the last decade, the integration of multidisciplinary investigation data in combination with the realization of 3D models of historic structures and complex monuments, are included in the standard processes for the assessment of their preservation state. Regarding the structural documentation of a historic building and its elements’ analysis, various steps have been made towards integration of various multidisciplinary data within a finite element model (FEM) for the optimum assessment [3,4,5,6,7,8,9].
