The uptake of digital twins in delivering infrastructure sector projects

PurposeThe anticipated strong growth of the infrastructure industry over the coming decades will require more modern, digital approaches to create data-centric infrastructure that allows infrastructure to be monitored and managed throughout its lifecycle. Digital twins (DTs) are currently at an early stage in terms of their implementation on infrastructure projects across the United Kingdom (UK). The purpose of this paper is to evaluate the current uptake of DTs in delivering infrastructure sector projects and how DTs can help contribute towards strengthening the industry.Design/methodology/approachA systematic literature review approach has been conducted with the research questions derived from the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) article screening tool. In addition to this, inclusion and exclusion criteria have been used to screen irrelevant information and help streamline research documents. Following a screening of relevant information, 36 pieces of literature were reviewed in order to identify the key drivers, barriers, enabling technologies and use cases.FindingsDTs have the potential to transform asset design, production and maintenance. However, to further advance the digital innovation in the UK infrastructure sector, further study is necessary. An emerging technology must be considered on a broader scale than just its technical aspects, particularly when it comes to DTs. With enabling technologies such as the Internet of Things (IoT), sensors and artificial intelligence (AI), the uptake of DTs appears promising. While current literature indicates that DTs offer clear benefits in the infrastructure sector, the uptake is low and hindered by both technical and non-technical challenges.Originality/valueThis paper provides a rich insight into the understanding and awareness of the DTs in delivering infrastructure sector projects and how the infrastructure sector has evolved in order to develop new ways of designing, constructing, operating and monitoring infrastructure assets. This study contributes towards informing leaders in the sector of the current uptake of DTs within the UK's infrastructure sector as well as how DTs can contribute towards strengthening the industry.

On PDF/A Conformance and Font Usage in PDF Documents Provided by Public Sector Organizations

The use of appropriate fonts and file formats for long-term maintenance of digital assets is a challenge for organizations in the public sector. The article reports from a study which investigated the PDF/A conformance and font usage in PDF files provided by Swedish public sector organizations (PSOs). This article presents an analysis of the PDF files' properties and font usage including a categorization of fonts' licenses. This study is motivated by the PDF/A-1 standard's requirement that ‘only fonts that are legally embeddable in a file for unlimited, universal rendering shall be used.' Analyzing PDF sets from three PSOs, the finding shows that the proportion of files that claim or succeed at conforming to PDF/A greatly varies among the sets despite similar backgrounds. Although the most popular way to make use of fonts is by embedding a subset of the font data, for some fonts expected to be ‘always available,' a considerable proportion of PDF files does not include any font data. This puts the onus of locating this data on the PDF reader which is problematic for long-term archival.

Wildland–Urban Interface: Definition and Physical Fire Risk Mitigation Measures, a Systematic Review

Due to the associated fire risk, the wildland–urban interface (WUI) has drawn the attention of researchers and managers from a range of backgrounds. From a land management point of view, it is important to identify the WUI to determine areas to prioritise for fire risk prevention. It is also important to know the fire risk mitigation measures available to select the most appropriate for each specific context. In this systematic review, definitions of the WUI were investigated and physical mitigation measures for reducing the risk of fire were examined from a land management perspective. The PRISMA 2020 Statement was applied to records published until 31 December 2022 and retrieved from the Web of Science, Scopus, and other research engines. A total of 162 publications from scientific journals and the grey literature were scrutinised and selected for analysis. Only publications providing an original definition of the WUI or proposing physical measures to reduce fire risk at the interface were retained, while those relating to emergency management and social perception were not considered. The risk of bias was reduced by internal cross-assessment by the research team. Definitions of the WUI (n = 40 publications) changed according to the research objective, varying broadly in identification of the anthropogenic and the wildland components of the interface. Terminology varied according to the definition, and the term wildland–human interface (WHI) was found to be more comprehensive than WUI. Methodological definitions of the interface ranged from using aggregated data through to identification of the buildings at risk in the interface with considerable precision. Five categories of physical fire risk mitigation measures (n = 128 publications) were identified: clearance distances, landscaping, wildland fuel management, land planning, and buildings design and materials. The most effective measures were those applied at early stages of urban development, and maintenance of assets and vegetation is crucial for preparedness. This review represents an analysis of scientific evidence on which land managers can base their actions to reduce the fire hazard risk in the WUI. The number of studies investigating the WUI is considerable, but experimental studies and quantitative results are scarce, and better communication and coordination among research groups and land management agencies is advisable. This systematic review was not registered.

Assessment framework for asset maintenance in passenger terminals

Asset management is an emerging discipline worldwide since most organisations are facing challenges in sustaining their operations with the ageing of assets. Moreover, managing of assets and the cost of maintenance are real-time challenges for organisations. Hence, the objective of this study is to develop a framework for predictive maintenance of assets considering the existing assessment frameworks of early researchers. The significance of this research is that the framework was developed focusing on passenger terminals where this concept had been narrowly addressed. The Kandy Multimodal Transit Terminal was selected as the case study. Accordingly, a Markov chain was used for developing the framework. A conceptual framework was introduced for the predictive maintenance of assets and cost projections considering the availability of data. The outcome of this research facilitates reduction of the consequences in asset maintenance management and management of the budget allocation for the maintenance in passenger terminals.

Biographical Reinvention: An Asset-Based Approach to Understanding the World of Men Living with HIV in Indonesia.

HIV diagnosis and management have often caused disruption to the everyday life and imagined futures of people living with HIV, both at individual and social levels. This disruption has been conceptualised, in a rather dystopian way, as 'biographical disruption'. This paper explores whether or not biographical disruption of living with HIV encourages men living with HIV (MLHIV; n = 40) in Yogyakarta and Belu, Indonesia, to reinvent their sense of self and future over time using internal and external assets. Our analysis uses the concepts of additive and subtractive resilience strategies, and we show how, rather than having a purely disrupted biography, participants talked about their experiences of 'biographical reinvention'. Study participants were recruited using the snowball sampling technique, beginning with two HIV clinics as the settings. Data were collected using one-on-one in-depth interviews, and a qualitative framework analysis was used to guide step-by-step data analysis. The findings showed that, despite the disruptions in their everyday lives (i.e., mental health condition, work, activities, social relationships, etc.) following the HIV diagnosis and management, MLHIV in our study managed to utilise their internal assets or traits (i.e., hope, optimism, resilience) and mobilised external resources (i.e., support from families, friends and healthcare professionals) to cope with the disruptions. An interweaving of these internal assets and external resources enabled them to take on new activities and roles (additive resilience strategies) and give up health compromising behaviours (subtractive resilience strategies). These were effective for most MLHIV in our study, not only to cope with the HIV repercussions and improve their physical and mental health conditions, but to think or work on a 'reinvented' biography which encompassed resilience, hope and optimism for better health, life and future. The findings indicate the need for HIV interventions and healthcare systems that provide appropriate support for the development and maintenance of internal assets of PLHIV to enable them to cope with the repercussions of HIV and work on a 'reinvented' biography.

Islamic Criminal Law Response on Physical Violence in the Household on Law No. 23 of 2004

In the perspective of Islamic criminal law, it does not recognize domestic violence. There are many arguments for naqli and aqli which teach fellow human beings to love one another and not to hurt each other either physically or psychologically. A husband should not feel superior and selfish in the household as well as a wife who should not be nusyuz. According to the majority of scholars, they define nusyuz as a wife’s deportment leaving out of the obligation to obey her husband or a deviant act that arises and is committed by a wife to her husband. Regarding domestic violence incidents that have been regulated in positive law, Islamic criminal law should also regulate these domestic violence incidents, but the Islamic criminal law literature has not explained in detail the sanctions for these domestic violence incidents. In this study, the authors used a type of literature review research, which is a type of research whose data sources are already available in libraries and digital access, which is normative research. The conclusion of Islamic criminal law perspective clarifies that if there is physical violence against a partner or family that causes death or injury and so on, then this is categorized as a jarimah of punishment in ta'zir. In a positive legal perspective, the sanctions for domestic violence against physical violence, this proves that the purpose of maqasid sharia in positive legal sanctions is related to the five aspects of maqasid sharia; preservation of religion, maintenance of soul, maintenance of off spring, maintenance of assets and maintenance of reason.

Digital Twins in the Construction Industry: A Comprehensive Review of Current Implementations, Enabling Technologies, and Future Directions

This paper presents a comprehensive understanding of current digital twin (DT) implementations in the construction industry, along with providing an overview of technologies enabling the operation of DTs in the industry. To this end, 145 publications were identified using a systematic literature review. The results revealed eight key areas of DT implementation including (i) virtual design, (ii) project planning and management, (iii) asset management and maintenance, (iv) safety management, (v) energy efficiency and sustainability, (vi) quality control and management, (vii) supply chain management and logistics, and (viii) structural health monitoring. The findings demonstrate that DT technology has the capacity to revolutionise the construction industry across these areas, enabling optimised designs, improved collaboration, real-time monitoring, predictive maintenance, enhanced safety practices, energy performance optimisation, quality inspections, efficient supply chain management, and proactive maintenance. This study also identified several challenges that hinder the widespread implementation of DT in construction, including (i) data integration and interoperability, (ii) data accuracy and completeness, (iii) scalability and complexity, (iv) privacy and security, and (v) standards and governance. To address these challenges, this paper recommends prioritising standardised data formats, protocols, and APIs for seamless collaboration, exploring semantic data modelling and ontologies for data integration, implementing validation processes and robust data governance for accuracy and completeness, harnessing high-performance computing and advanced modelling techniques for scalability and complexity, establishing comprehensive data protection and access controls for privacy and security, and developing widely accepted standards and governance frameworks with industry-wide collaboration. By addressing these challenges, the construction industry can unlock the full potential of DT technology, thus enhancing safety, reliability, and efficiency in construction projects.

TINJAUAN MAQASID SYARI’AH TERHADAP PENCATATAN PEKAWINAN

The Indonesian Muslim community is still faced with the problem of two understandings of marriage registration. First, the registration of marriages is considered a legal requirement for marriage, so that unregistered marriages (sirri) are considered as marriages that have no legal force. The provisions for the obligation to register a marriage are contained in Law no. 1 of 1974 Article 2 paragraph (2); jo. Articles 4 and 5 KHI. Second, the understanding that judges that even without marriage registration, the marriage is considered valid according to religious law, if the fiqh requirements and harmony are met, this opinion also rests on Law No. 1 of 1974 Article 2 paragraph (1), which restores the validity of marriage based on each religious law. This article aims to reaffirm the position of registering marriage as a necessity when viewed from the perspective of maqasid shari'ah. This study uses a qualitative normative approach, with secondary data sourced from searching books, laws, and various related literature. The results of the study show that the status of marriage registration is purely the result of ijtihad, and in essence it is in line with the goals of syara' and does not violate the benefit, namely the maintenance of religion and lineage by creating an orderly administration. Likewise, the maintenance of human assets in the context of marriage, because with legal force, a marriage can anticipate the implications of a legal action.

Maqasid Sharia Analysis of The Welfare Level of Muslim’s Ceramic Craft in Plered Purwakarta

Introduction: The activity of making ceramics is a work that has been passed down from generation to generation from the ancestors of the Plered people until now. Amid its existence, the number of craftsmen in 2019 decreased to 163 from the previous number of 205 craftsmen. This study aims to determine Muslim ceramic craftsmen’s welfare level in the review maqaṣhid syari'ah in Plered District, Purwakarta Regency. Research Methods: Research data sources are primary and secondary data. A sample of 114 craftsmen was obtained through the Simple Random Sampling technique. Data collection techniques are observation, documentation, and questionnaires. The analysis technique used is a quantitative descriptive analysis technique with a percentage formula through a Likert scale assessment tool. Results: The results of this study indicate that overall Muslim ceramics craftsmen who are classified as high welfare criteria are 38 people (33.3%), 74 people (64.9%) are at the moderate welfare level, 2 people (1.8%) are classified as low welfare level, and there are no craftsmen with very low or very high welfare criteria. The determinants of the level of welfare of Muslim ceramic craftsmen are through hifdzu din, hifdzu nafs, hifdzu 'aql, hifdzu nasl, and hifdzu maal. In this case, the indicator of asset maintenance (hifdzu maal) the majority of craftsmen belong to the highest welfare criteria compared to other indicators, which is 95 people (83.3%).

A SCAN-TO-BIM PROCESS FOR THE MONITORING AND CONSERVATION OF THE ARCHITECTURAL HERITAGE: INTEGRATION OF THEMATIC INFORMATION IN A HBIM MODEL

Abstract. Conservation actions often challenge traditional planned conservation tools, especially when referring to the management of data relating to the existing building heritage due to the huge amount of information to be acquired and archived. In response to this requirement, the Building Information Modelling (BIM) process, applied to historical buildings as Historical-BIM (HBIM), could be an effective solution for integrating different types of data concerning not only the geometric features but also useful qualitative information in conservation and preservation works (i.e. the type of materials, construction techniques, the presence of degradation and instability, intervention techniques, etc.). Although the BIM process has reached a considerable level of maturity, several aspects related to the application of the method to existing structures through the Scan-to-BIM process require further research; particularly the need to find suitable approaches to integrate, manage and store thematic information. The article describes the work carried out in the case study of Villa Castelnuovo, an eighteenth-century architectural building located in Palermo (Italy), in which, starting from an integrated survey, it was possible to generate an HBIM model to support all the phases concerning preventive maintenance, long-term redevelopment and management of the architectural asset. The research focused mainly on the modelling and information integration phases, developing a procedure applicable to different contexts for storing, managing and analysing the external façade decay necessary for documenting and monitoring the architectural heritage.

Structural Health Monitoring of Large-Scale Geomembrane Floating Covers Using Solar Energy

High-density polyphenylene geomembranes are utilized as large-scale floating covers in anaerobic water treatment plants for the purpose of collecting renewable biogas energy and preventing the emission of odorous by-products. During degradation, the accumulation of scum, the presence of biogas pockets and sewage can negatively impact the structural integrity of the covers and hinder degradation efficiency. Traditional methods are insufficient in identifying the substances under the covers. In this study, a thermography technique was developed and tested in lab-scale experiments using ambient weather information to inspect the geomembranes. The technique was then applied to a remote monitoring investigation of large-scale floating covers located at a sewage treatment plant. Long-term monitoring of two regions on the covers was conducted using a thermal camera, with ambient weather information recorded to help analyze temperature changes. The acquired thermal image sequences were analyzed, resulting in the creation of a segmented cover map indicating the profiles of substances. The results of the on-site thermal imaging field trials verify the effectiveness of the developed remote sensing thermography technique, which has the potential to assist in future asset maintenance, remove scum efficiently and enhance anaerobic degradation efficiency at sewage water treatment plants.

BIM enabler for facilities management: a review of 33 cases

The purpose of this paper is to investigate the application of building information modelling (BIM) for asset management. It will discuss what tools and processors are used for applying BIM for asset management in construction projects. The method comprises a literature review of 33 projects that have applied BIM or planned to apply BIM for asset management functions. The findings show that a combination of software, hardware, processors, and standards can enable the BIM models to be integrated with the asset management systems. It facilitates easy extraction of information, avoid errors and duplication of work. The most popular way of developing a BIM-based asset management system is incorporating BIM asset data with CMMS or CAFM systems used for asset lifecycle and maintenance management. Engagement of stakeholders related to the operation phase is required as early as possible. Consideration should be given for protecting the information generated within the cyber environment. The research shows how BIM related tools and processors could be integrated to successfully implement BIM enabled asset management. The knowledge can be potentially useful for planning or implementing BIM enabled asset management systems. The research provides insight on the application of BIM for asset management in construction projects globally.

Recommending Words Using a Bayesian Network

Asset management involves the coordinated activities of an organisation to derive value from assets, which may include physical assets. It encompasses activities related to design, construction, installation, operation, maintenance, renewal, and asset disposal. Asset management ensures the coordination of all activities, resources, and data related to physical assets. Recording and monitoring all maintenance activities is a key part of asset management, often done using work orders (WOs). Technicians typically create WOs using “free text”, which can result in missing or ungrammatical words, making it difficult to identify trends and analyse information. To standardise the terminology used for the same asset maintenance operation, this paper proposes a method that suggests words to technicians as they complete WOs. The word suggestion algorithm is based on past maintenance records, and a Bayesian network-based recommender system adapts to present needs verified by technicians using implicit user feedback. Implementing this system aims to normalise the terms used by technicians when filling in a WO. The corpus for this work comes from asset management records collected in a health facility in Portugal operated by a private company.

Maintenance planning innovation: realising planning and execution efficiencies through process and digital transformation

As oil and gas facilities age, the need to allocate finite planning effort across mounting scopes of work increases. Woodside has tackled this problem head-on, seeking innovative solutions to reduce waste in deploying low-complexity asset maintenance. Through its Accelerator Programme, Woodside has employed new capabilities – such as enterprise design thinking and agile at scale delivery – conducting over 200 interviews and prototype tests to deeply understand maintenance priorities and identify opportunities to realise value, organisation wide. The result is an in-house scope management application, which supports the end-to-end maintenance planning workflow. The application considers multiple data points on thousands of work orders in seconds, using a sophisticated algorithm to incorporate industry knowledge and business priorities specific to Woodsides’ needs. The application produces a maintenance plan optimised by understanding location, equipment and process efficiency drivers to ensure the best utilisation of resources. The embedding of intelligent automation represents a cultural shift, enabling a move towards a more dynamic maintenance planning process that responds to changing asset priorities. Currently, 41% of all North-West Shelf Gas Project scopes are managed through the application. A 95% reduction in selection time and a 90% reduction in overall planning duration have been realised from this initiative. By releasing valuable planning effort back to the business to focus on complex scope, Woodside can realise and maintain safe, reliable and efficient operations in a low-cost, variable environment.

Multi‐type defect detection and location based on non‐destructive impedance spectrum measurement for underground power cables

AbstractPower cable defect detection and location is a crucial aspect in power asset maintenance. Impedance spectrum measurement can be used as a non‐destructive tool for cable monitoring. Defects from overheating and moisture ingress are investigated by the authors, and it is shown that multi‐type cable defects can be detected and located by this methodology. With both electromagnetic analysis and experimental investigation, the relation between impedance variation and the dielectric permittivity is studied to reveal the method's mechanism. An approach to implement such impedance measurement online is proposed and its perspectives in terms of sensitivity is investigated by field scale tests. It is shown that 2% impedance variation due to defect should be detectable. Field scale tests show perspectives for online application with signal coupling through a high‐frequency current transformer with focus on the differences in waveforms obtained from the impedance measurements.

Terrestrial Laser Scanning for 3D Assets Registry

This study aimed to assess the feasibility of using terrestrial laser scanning (TLS) technology for creating 3D asset registries in facilities management. The research utilized a case study approach to scanning an industrial facility, and the resulting data was processed to create a 3D model of the assets. The study found that TLS technology can produce highly accurate and detailed 3D models of assets, which can aid in asset management and maintenance. However, the technology has some limitations, such as cost and the need for skilled operators. The study suggests that TLS technology can be a valuable tool for asset management and recommends further research in this area.
