“…Some Terrestrial laser scanners (TLS) are based on the triangulation principle as well [2,18,53,56]. They produce a point cloud of the scanned object [49], which needs to be post-processed and then is transformed into a 3D model [4,8,18,49,57,58]. Point clouds post-processing is still a time-consuming task [23,29,57], even if there have been some attempts to speed it up [15,48,49,59,60].…”

“…• Noise elimination [8,18,23], which consists in detecting and eliminating scanned items that are not part of the case study; • Point cloud registration [8,18,49,57,58], which consists in merging different point clouds of the same object, deriving from different scanning sessions; • Meshing [18,29,57], which consists of creating triangulated surfaces to be turned into 3D models afterwards-to be done with specific software.…”

BIM for heritage science: a review

Building Information Modelling (BIM) is a new process that is spreading in the Architecture, Engineering and Construction field. It allows the creation of virtual building models, which can be linked to numerical data, texts, images, and other types of information. Building components, such as walls, floors, etc. are modelled as "smart objects", i.e. they are defined by numerical parameters, such as dimensions, and are embedded with other kinds of information, such as building materials and properties. Stored data are accessible and modifiable by all different professionals involved in the same project. The BIM process has been developed for new buildings, and it allows to plan and manage the whole building life-cycle. BIM for built heritage has started to be researched recently, and its use is still not widespread. Indeed, built heritage is characterised by complex morphology and non-homogeneous features, which clash with BIM's standardised procedures. Moreover, to date, BIM does not allow fully automated procedures to model heritage buildings. This review focuses on the survey and digitisation phases, which can be seen as the initial phases of application of BIM in conservation projects. It also briefly covers the modelling stage. Here we present the main methodologies developed for BIM for built heritage. Issues about digitisation are also highlighted, principally in connection with the unavailability of automated processes. During the last 10 years, research has led to promising results; for example, videogame interfaces have been used to simulate virtual 3D tours that display in a single interface the 3D model and the database containing metadata, and new software plug-ins have been developed, to easily create "smart objects". Nevertheless, further research is needed to establish how BIM can support the practice of building conservation. There is a gap in BIM's information holding capacities, namely the storage of cultural and historical documentation, as well as monitored and simulated data relevant for preventive conservation. Future work should focus on the development of new tools that will be able to store and share all the relevant metadata.

“…Another application is for surveying purposes where laser scanning processes have been used for slope mapping (Taher, 2014) or common topographic high resolution surveying (Luh et al , 2014). Built environment-related applications included the use of laser scanning for 3 D documentation of historical monuments (Wei et al , 2010; Majid et al , 2016; Basir et al , 2014) or interior and exterior scan of regular buildings (Ashim et al , 2011). As an example for the construction phase, Aziz et al (2016) used a laser scanner to take accurate measurements of precast concrete components, and Autodesk Revit have been used for Modeling.…”

Purpose Three dimensional (3 D) laser scanner surveying is widely used in many fields, such as agriculture, mining and heritage documentation and can be of great benefit for as-built documentation in construction and facility management domains. However, there is lack of applied research and use cases integrating 3 D laser scanner surveying with building information modeling (BIM) for existing facilities in Malaysia. This study aims to develop a scan to as-built BIM workflow to use 3 D laser scanner surveying and create as-built building information models of an existing complex facility in Malaysia. Design/methodology/approach A case study approach was followed to develop a scan to as-built BIM workflow through four main steps: 3 D laser scanning, data preprocessing, data registration and building information modeling. Findings This case study proposes a comprehensive scan to as-built BIM workflow which illustrates all the required steps to create a precise 3 D as-built building information model from scans. This workflow was successfully implemented to the Eco-Home facility at the Universiti Teknologi Malaysia. Originality/value Scan to as-built BIM is a digital alternative to manual and tedious process of documentation of as-built condition of a facility and provides a detail process using laser scans to create as-built building information models of facilities.

“…The need to develop a methodology for documentation, diagnostics, and monitoring of built heritage has been the subject of many recent studies [2][3][4][5]. The approach of these studies is for a digital documentation of the conservation state of buildings [2,3], including 3D modelling and GIS mapping, and the integration of diagnostics data through a knowledge-based information system [4] or within building information modeling (BIM) [5] for documenting damages to built heritage. Nevertheless, there are still challenging research topics to address: in particular, the multidisciplinary integration of tools and methods used in different fields and/or with different purposes, and the multi-level correlation of data by different analytical and experimental documents and sources aimed at a complete characterization of stone weakness.…”

A Multidisciplinary Methodology for Technological Knowledge, Characterization and Diagnostics: Sandstone Facades in Florentine Architectural Heritage

et al. 2022

View full text Add to dashboard Cite

The Historic Center of Florence, a UNESCO World Heritage Site, includes many examples of architecture characterized by rough-hewn rusticated block facades—a very common masonry technique in the Florentine Renaissance—made in Pietraforte sandstone. The latter features numerous criticalities related to its intrinsic characteristics and to decay phenomena that are due to weathering and pollution. A multidisciplinary methodology has been developed starting from historic analysis and architectural survey to a complete optometric, mechanical, physical, mineralogical, and petrographic characterization of rough-hewn rusticated blocks, applied to the case study of the Palazzo Medici Riccardi facades. The studies performed in this work cover several research fields, from architecture to geology, going through material diagnostics, and aim at improving knowledge and designing new restoration solutions for Pietraforte building-material criticalities. The research proposes an operative protocol aimed at supporting restoration projects and monitoring plans, with the aim to protect historical, architectural, and artistic cultural heritage and to safeguard the people who visit the city of Florence every year.
