Visual Data Analytics

In most construction and Infrastructure management projects, it is important to ensure and maintain the performance, safety as well as quality in the work to execute the construction in expected period , for monitoring the above parameters i.e. Performance, Safety, Quality and as well as Security, requires data to analyze, determine and test the algorithms, due to eternal increase amount of captured data thorough modern improvements in  technology i.e. devices, camera equipped vehicles, Sensors, etc. accommodates an innovative scope to capture present status of construction sites at a less cost analogized to more alternative techniques such as laser scanning technique. Vast endeavours on documenting as-built status, nevertheless, stay at retrieving the visual data and updating Building Information Model (BIM). Hundreds of images and videos are captured but most of the data becomes scrap without proper localize with plan document and time. To take full benefits of visual data for construction status analytics where performance analytics is also included in it, three aspects (reliable, relevance and speed) of capturing, analysing and reporting visual data are captious and tracking development in construction sites needs two direction communication between field crew and management so that performances and changes issues related to task management, completion and outlook can be convey effectively. This paper deals with the investigation of current techniques for influence with help of arising BIM and big data in performance monitoring at construction from reliable, relevance and speed.

<p><strong>Abstract.</strong> This study is part of the “Milan Cathedral Survey project”. It is a three years long research project with the aim of surveying the entire cathedral in 3D with different techniques (mainly photogrammetry and laser scanning). The goal is to renew the architectonic drawings (sections elevations and plans) to obtain new updated and certificated measurements of the cathedral, as requested by Veneranda Fabbrica del Duomo, and to produce the basis on which to build a future 3D BIM (Building Information Model) system implementation. In this paper, we would like to examine in depth the survey process of the exterior elevations of the cathedral carried out using photogrammetry as the main survey technique for orthophotos production. The case studies here presented have the goal of underlying challenges, discussing decisions and approaches, describing the followed pipeline and of defining a standard method that can be followed to produce gigapixel orthophotos of complex cultural heritages.</p>

Informative Content

<p><strong>Abstract.</strong> Informative models are not limited only to new construction or existing building but can also be used (also been used) for large infrastructure management like bridges. The adoption of informative content models for structural health monitoring (SHM) of such infrastructures poses some issues that need to be solved in order to develop smooth management and maintenance workflows. This paper describes a novel methodology for the generation of a detailed BIM of a complex medieval bridge and the possibility to link specific data coming from load testing. Integration of information coming from different data sources is one of the most important aspects for the development of maintenance programs. However, each actor in the process makes use of different strategies and protocols whose integration can generate bottlenecks. To partially overcome this limitation a cloud-based solution was used, and a Building Information Model (BIM) of the bridge was used as main collector of information for the different stakeholders involved in its management.</p>

This study proposed a phased reverse engineering framework to construct cultural heritage archives using laser scanning and a building information model (BIM). This framework includes acquisition of point cloud data through laser scanning. Unlike previous studies, in this study, a standard for authoring BIM data was established through comparative analysis of existing archives and point cloud data, and a method of building valuable BIM data as an information model was proposed. From a short-term perspective, additional archives such as member lists and drawings can be extracted from BIM data built as an information model. In addition, from a long-term perspective, a scenario for using the cultural heritage archive consisting of historical records, point cloud data, and BIM data was presented. These scenarios were verified through a case study. In particular, through the BIM data building and management method, relatively very light BIM data (499 MB) could be built based on point cloud data (more than 917 MB), which is a large amount of data.

<p><strong>Abstract.</strong> There are multiple conservation challenges related to decorated surfaces, the majority are intimately linked to its documentation. This paper draws on wall paintings as a representative of decorated surfaces, arguing the importance of considering its fourthdimensionality &amp;ndash; space and time &amp;ndash; in its conservation and documentation. To that end, we propose the use of Building Information Model (BIM) as a platform to consolidate this approach together with various documentation techniques used for the conservation and management of wall paintings. This paper exemplifies this method with a case study of Myin-pya-gu Temple in Old Bagan (Myanmar); firstly, reviewing the different techniques used to document the temple and wall painting (photography, photogrammetry, laser scanning, reflectance transformation imaging (RTI); and secondly, discussing the data integration within a BIM environment. This position proposes a transition from a two-dimensional to a four-dimensional approach in wall painting conservation, potentially opening up possibilities of documentation, monitoring, simulation, or dissemination. Ultimately, the case study of Myin-pya-gu has the objective to introduce the use of HBIM as a platform for consolidating the documentation of decorated surfaces.</p>

Construction Progress Monitoring

With the spread of camera-equipped devices, massive images and videos are recorded on construction sites daily, and the ever-increasing volume of digital images has inspired scholars to visually capture the actual status of construction sites from them. Three-dimensional (3D) reconstruction is the key to connecting the Building Information Model and the project schedule to daily construction images, which enables managers to compare as-planned with as-built status and detect deviations and therefore monitor project progress. Many scholars have carried out extensive research and produced a variety of intricate methods. However, few studies comprehensively summarize the existing technologies and introduce the homogeneity and differences of these technologies. Researchers cannot clearly identify the relationship between various methods to solve the difficulties. Therefore, this paper focuses on the general technical path of various methods and sorts out a comprehensive research map, to provide reference for researchers in the selection of research methods and paths. This is followed by identifying gaps in knowledge and highlighting future research directions. Finally, key findings are summarized.

Project and digital strategies for a built heritage and its landscape in the coastal fortifications system of Northern SardiniaThe research will deal with new methods about project and digital strategies: first starting from digital survey, operated with 3D laser scanner and photogrammetry procedures, allowing, through various operations, coordinated in a workflow to obtain a single point-cloud, derived from the alignment of all scan, to generate a complex 3D model, so called Building Information Model for Heritage (BIM-H). The present research project aims to investigate and systematize, the new digital restitution strategies of the fortification existing through laser scanning and digital mapping, in particular, on military structures, as well as reflect on the problem of protection and managing this specific kind of built heritage today so far from the motivations that once determined its construction. Choosing two case studies, belonging to the coastal fortifications system of Northern Sardinia, built in the same historical period, Forte Cappellini and Punta Rossa, analyze the common constructive characters, the relationship with nature and their current state of conservation, going to verify the possibility of sharing methodologies and strategies of appropriate project. Passing from an isolated and static vision of work files to one that will be shared and dynamic, it will be possible to offer “food for thoughts” in various areas and disciplines related to Architecture, which will be able to interface simultaneously and work in progress, enriching its content and know-how. The outcome of the study will allow to recognize the emergence of a new strategy of scientific investigation and design able to positively influence the protection and conservation of military architecture of our peninsula, suggesting theoretical and operational guidelines of different nature, often in shorter times and with results almost unimaginable before, allowing for further analysis and developments the same model in future.

AbstractOne of the most important parts of construction work is the verification of the geometry of the parts of structures and buildings constructed. Today this procedure is often semi- or fully automated. The paper introduces an approach for the automated verification of parts of buildings, by comparing the design of a building (as-planned model), derived from a Building Information Model (BIM) in an Industry Foundation Classes (IFC) exchange format to a terrestrial laser scanning (TLS) point cloud (as-built model). The approach proposed has three main steps. The process begins with the acquisition of information from the as-planned model in the IFC exchange format; the second step is the automated (wall) plane segmentation from the point cloud. In the last step, the two models mentioned are compared to determine the deviations from the design, and the as-built wall flatness quantification is also executed. The potential of the proposed algorithm is shown in a case-study.
