Data-driven conservation actions of heritage places curated with HBIM

Abstract

Digital surveying tools provide a highly accurate geometric representation of cultural heritage sites in the form of point cloud data. With the recent advances in interoperability between point cloud data and Building Information Modelling (BIM), digital heritage researchers have introduced the Heritage/Historic Information Modelling (HBIM) notion to the field. As heritage data require safeguarding strategies to ensure their sustainability, the process is closely tied to conservation actions in the architectural conservation field. Focusing on the intersection of the ongoing trends in HBIM research and the global needs for heritage conservation actions, this paper tackles methodological pipelines for the data-driven management of archaeological heritage places. It illustrates how HBIM discourse could be beneficial for easing value-based decision-making in the conservation process. It introduces digital data-driven conservation actions by implementing a novel methodology for ancient building remains in Erythrae archaeological site (Turkey). The research ranges from a) surveying the in-situ remains and surrounding stones of the Heroon remains with digital photogrammetry and terrestrial laser scanning to b) designing a database system for building archaeology. The workflow offers high geometric fidelity and management of non-geometric heritage data by testing out the suitability and feasibility for the study of material culture and the physical assessment of archaeological building remains. This methodology is a fully data-enriched NURBS-based (non-uniform rational basis spline) three-dimensional (3D) model—which is integrated and operational in the BIM environment— for the holistic conservation process. Using a state-of-the-art digital heritage approach can be applied from raw data (initial stages) to decision-making about an archaeological heritage site (final stages). In conclusion, the paper offers a method for data-driven conservation actions, and given its methodological framework, it lends itself particularly well to HBIM-related solutions for building archaeology.

Condition Assessment of Heritage Buildings via Photogrammetry: A Scoping Review from the Perspective of Decision Makers

“…For example, Santagati et al (2019) propose a workflow where 2D decay maps deriving from photogrammetric images are transformed into measurable parametric surfaces, within the HBIM environment [118]. HBIM also provides a framework and a tool supporting rapid seismic vulnerability assessment, always starting from a Structurefrom-Motion survey, from which constructive characteristics, materials and conservation conditions have been determined [119][120][121]. A further development is represented by the work of Pavlovskis et al ( 2019), wherein a photogrammetric-based HBIM 3D model, in combination with multiple-criteria decision-making techniques, has been exploited to finalize diagnosis into a selection of the best interventions to perform on the heritage in order to guarantee its preservation [122].…”

Bridging the Gap: An Open-Source Gis+bim System for Archaeological Data. The Case Study of Altinum, Italy

“…Experimental applications of BIM methodology to archaeological sites are still remarkably limited. The results of a recent survey of scientific publications show that about fifteen projects have been carried out to date, all with very different approaches to the subject (Yajing and Cong, 2011;Scianna, Gristina and Paliaga, 2014;Achille, Lombardini and Tommasi, 2015;Garagnani, Gaucci and Govi, 2016;Cera, 2017;Trizio, Savini and Giannangeli, 2018;Bosco et al 2019;Banfi 2020;Diara and Rinaudo, 2020;Moyano et al, 2020;Bosco et al, 2021;Guerrero Vega and Pizzo, 2021;Banfi et al, 2022;Saricaoglu and Saygi, 2022). In the scientific discussion on BIM, archaeological case studies have often fallen under the HBIM label.…”

HBIM for restoration project and data management of a religious complex

“…The process of using a scan-to-BIM approach to develop parametric models of historic buildings to represent the geometry of artefacts, enriching it with the integration of non-geometrical data and thus semantization into a knowledge-based workflow whose aim is to share this data with conservation specialists is now considered wellestablished [4]. One of the potentials of HBIM procedures is its ability to concentrate a large variety of heterogeneous data representative of the complexity that characterizes the built heritage in a single environment [4]. In literature, information management's topic within HBIM has been extensively addressed concerning data management to facilitate decision-making in preventive and planned conservation.…”
