Abstract

Abstract. The need to safeguard and preserve Cultural Heritage (CH) is increasing and especially in Italy, where the amount of historical buildings is considerable, having efficient and standardized processes of CH management and conservation becomes strategic. At the time being, there are no tools capable of fulfilling all the specific functions required by Cultural Heritage documentation and, due to the complexity of historical assets, there are no solution as flexible and customizable as CH specific needs require. Nevertheless, BIM methodology can represent the most effective solution, on condition that proper methodologies, tools and functions are made available. The paper describes an ongoing research on the implementation of a Historical BIM system for the Parma cathedral, aimed at the maintenance, conservation and restoration. Its main goal was to give a concrete answer to the lack of specific tools required by Cultural Heritage documentation: organized and coordinated storage and management of historical data, easy analysis and query, time management, 3D modelling of irregular shapes, flexibility, user-friendliness, etc. The paper will describe the project and the implemented methodology, focusing mainly on survey and modelling phases. In describing the methodology, critical issues about the creation of a HBIM will be highlighted, trying to outline a workflow applicable also in other similar contexts.

Highlights

  • In recent years, the need to safeguard and preserve Cultural Heritage (CH) is increasing and it should represent a large investment field with returns in economic growth, employment and social cohesion

  • The experimentation carried out in this research shows that the use of HBIM in the cultural heritage field is a good solution and a potential for more coordinated and efficient management and preservation

  • A widespread application of HBIM system to cultural heritage buildings requires a large investment in terms of costs, training and processing times

Summary

INTRODUCTION

The need to safeguard and preserve Cultural Heritage (CH) is increasing and it should represent a large investment field with returns in economic growth, employment and social cohesion. Its main goal was to give a concrete answer to the lack of specific tools required by Cultural Heritage documentation: organized and coordinated storage and management of historical data, easy analysis and query, time management, 3D modelling of irregular shapes, flexibility, user-friendliness, etc. The application was implemented with the specific aim of providing tools for non- AEC experts: it gives user-friendly graphical interfaces to access the data and makes available tools for data entry, element modelling, attribute query and thematic mapping. It can be integrated into the main commercial BIM software (at the moment the experimentation has been limited to Autodesk Revit (Autodesk, 2018)) or accessed via web. In this paper the Cathedral of Parma was chosen as case study, but the implemented methodology can be applied to other similar historical buildings
