Digital technologies are radically transforming project delivery, breaking the mould of 1960s approaches to enable more rapid and agile forms of organizing. Yet the use of large digital data-sets also requires new forms of control. This study compares the leading practices of managing change in digitally-enabled projects in Airbus, CERN and Crossrail. It focuses on configuration management, the process of maintaining system integrity while handling change to both the digital data-set and the related realworld engineering systems. The contribution is to explain: first, why configuration management has become more, rather than less, important in complex engineering in an era of 'big data'; and second, how approaches to configuration management are shaped by these industrial contexts of civil engineering, nuclear research and aerospace. The paper concludes by considering the implications for managing digitally-enabled projects.

Landscape Architecture deals with the creation of spaces in the landscape that benefits society and ecology for which landform is an important part of the design and realisation. Landscape architects are posed for more involvements in the realisation processes, which can include, as well as ascetics and selection of materials design, scheduling, estimation, phasing, and optimisation of landscape architect projects. However, Current Landscape site processes are affected by numerous inefficiencies from the early specification of site surveys through the development of design to site operations. These are due to poorly integrated processes among clients, Landscape Architects, Engineers and site and the lack of processes and technologies for optimising information flow and cut/fill site operations. The prime objective of the research is to develop and adopt a prototype incorporating optimisation technologies to identify optimal relationship between project variables (cut/fill quantities, cost, aesthetics and schedules) underpinned by BIM technologies and processes. This is an on-going project and this paper only outlines the prototype to optimise cut/fill quantities in 3D CAD environment. The paper also discusses the results of case studies and tests the user-friendliness, accuracy/reliability/repeatability of results obtained with different prototype functionalities.

Traditionally, information flow in the built environment concentrates on the needs of the design and construction, rather than on the operation. This leads to inconsistencies and disruption within stages, clearly found at handover of information. It commonly hinders delivery of client's requirements for the operation of buildings along the project development as well. A structured information delivery enabled by BIM protocols, established at project's inception, could prevent information loss during the project development. It could as well ensure the coordinated delivery of the clients' requirements as stated at the pre-design stage, and help anticipating the impact of clients' decisions at early project stages on operations performance. In this paper, a methodology to obtain, categorize and weigh sustainability and facility management values with the subjective driven priorities from high level management is outlined as part of a decision support system. The latter will assist, in the context of a digital project delivery, in translating these priorities into objective parameters and information categories to include within the bidders' BIM Execution Plans. Additionally, it will help in checking compliance with both sustainability and client's goals during the project development and judge them appropriately focusing on the building operation applied to the Qatar context.

This paper presents a new approach to translate between Building Information Modeling (BIM) and Building Energy Modeling (BEM) that uses Modelica, an object-oriented declarative, equation-based simulation environment. The approach (BIM2BEM) has been developed using a data modeling method to enable seamless model translations of building geometry, materials, and topology. Using data modeling, we created a Model View Definition (MVD) consisting of a process model and a class diagram. The process model demonstrates object-mapping between BIM and Modelica-based BEM (ModelicaBEM) and facilitates the definition of required information during model translations. The class diagram represents the information and object relationships to produce a class package intermediate between the BIM and BEM. The implementation of the intermediate class package enables system interface (Revit2Modelica) development for automatic BIM data translation into ModelicaBEM. In order to demonstrate and validate o...

The research presented here reports on current advances in tying simulation and analysis of environmental building performance to design authoring software. A brief review of developments leading up to the convergence between design authoring and environmental performance testing helps to explain the current status-quo. Many of the applications available today are rooted in early research efforts that date back to the early days of Personal Computers (or even before). A small case study complements the historic review and offers some perspectives about tool selection in an educational design-studio setting.

El uso de herramientas BIM aplicadas al patrimonio (HBIM) ha demostrado ser un instrumento eficaz para la conservación, documentación y gestión del patrimonio arquitectónico[1], [2], [3]. Sin embargo, uno de los principales desafíos radica en la interoperabilidad de los datos y su adecuación a los procesos de análisis, control y toma de decisiones. La presente investigación propone un procedimiento basado en el uso combinado de Revit y Dynamo para la extracción y estructuración automatizada de datos geométricos y cualitativos, generando tablas paramétricas y archivos Excel que permiten su visualización, análisis y exportación.
El objetivo es establecer una metodología reproducible que facilite el intercambio de información entre plataformas y disciplinas, especialmente en contextos multidisciplinares de conservación patrimonial [4], [5]. La metodología ha sido aplicada sobre un caso práctico de arquitectura histórica, el castillo de Huelma, permitiendo evaluar su eficacia tanto en la automatización de procesos como en la legibilidad y utilidad de la información generada para técnicos del ámbito de la conservación.
Los resultados obtenidos han permitido validar el flujo de trabajo propuesto como una herramienta eficiente en contextos de documentación y diagnóstico, fomentando la interoperabilidad entre modelos HBIM y sistemas externos de gestión de datos. Se concluye que esta integración técnica contribuye a optimizar procesos en las fases de intervención sobre el patrimonio, garantizando una mejor trazabilidad y coherencia documental.

3,4-méthylènedioxypyrovalérone (MDPV) et méthoxétamine (MXE) font partie des nouvelles substances dites « récréatives » facilement obtenues sur Internet. Neuf cas d'exposition à ces substances sont rapportés pour 8 patients, l'un d'entre eux ayant consommé les 2 produits. Méthodes : Plusieurs approches analytiques sont décrites par CLHP/UV-BD après extraction alcaline éventuellement suivie d'une réextraction acide, par CPG/SM après extraction alcaline et par CLHP/SM-SM après simple précipitation des protéines. Résultats : Les concentrations plasmatiques mesurées dans les prélèvements d'admission sont, pour la MDPV, égales à 45 μg/L et inférieure à la limite de quantification et, pour la MXE, comprises entre 122 et 366 μg/L sauf 1 cas inférieur à la limite de quantification. Les concentrations urinaires sont comprises entre 0,3 et 165 mg/L selon le produit et les patients. Plusieurs métabolites supposés sont mis en évidence comme la N-deséthyl-MXE et la O-déméthyl-N-deséthyl-MXE. Les symptômes décrits sont tachycardie, hypertension artérielle, agitation, convulsions et coma. Deux patients ont nécessité des soins de réanimation. L'évolution était favorable pour tous. Conclusion : Si la MDPV vient d'être classée comme stupéfiant en France, la MXE bénéficie encore d'une absence de statut. L'augmentation des données clinico-biologiques concernant cette substance doit conduire à une réflexion sur un classement futur comme stupéfiant.

The rapid evolution of computer science, propelled by advancements in Artificial Intelligence (AI) and Quantum Computing, has significantly transformed the cyber threat landscape. These developments have introduced sophisticated cyberattack vectors that challenge traditional security paradigms. Notably, air-gapped systems-networks physically isolated from unsecured networks-once considered impervious to cyber threats, are now vulnerable due to emerging attack methodologies. This paper explores the integration of Blockchain Technology (BCT) and AI to fortify cybersecurity measures within closed network systems. Blockchain's decentralized and immutable ledger ensures data integrity, traceability, and authentication, while smart contracts automate security protocols. Concurrently, AI-driven machine learning algorithms facilitate real-time anomaly detection and predictive threat analysis, establishing a proactive defense mechanism. We propose a permissioned blockchain architecture to regulate access, coupled with AIpowered anomaly detection systems trained on diverse datasets to enhance accuracy. This integrated model aims to provide comprehensive protection, ensuring data confidentiality, integrity, and availability against evolving cyber threats. The synergistic application of these technologies underscores the necessity for continuous innovation and collaboration to safeguard industrial and national security in the digital battlefield.

Building Information Modeling (BIM) enables collaborative data transfer between architects and engineers throughout the entire building's life cycle. While BIM examines physical parameters and management processes, it presents challenges in architectural acoustic analysis. This study aims to evaluate acoustic effects and perform room acoustic analyses in BIM tools that enable significant productivity gains in the construction industry and digitally support the planning, construction, and operation of structures. The research focuses on the prediction of the reverberation time, which is a main acoustics parameter. The literature review was conducted with a comprehensive bibliometric analysis. Using Autodesk Ecotect, acoustic analyses were performed on an educational building as a case study. Reverberation times were calculated at midfrequencies (500, 1000, 2000 Hz) in 1/3 octave bands. Suggestions to reduce high reverberation times due to reflective room conditions were developed and tested within the BIM tool. In conclusion, it was emphasized that design/renovation/improvement scenarios for acoustic analysis can be tested with BIM. It has been determined that the determination of the level of effect of other components with acoustic treatments made on BIM platforms can also provide added value to the projects designed according to outsourcing acoustic software.

The restitution of heritage with virtual survey of cloud points of buildings to be demolished is of great importance both for culture and for the management of the city. The specific case of the Guruyú tenement, in the Old City of Montevideo, represents a typical way of living for a large part of the Afro-descendant population-and other migrant minorities-of Uruguay, which characterized a way of life and which, due to the new Hygiene standards at the beginning of the 20th century were becoming obsolete. Currently that property, one of the last of its category, is in danger of collapsing due to its dilapidated state. The importance of patrimonial restitution then lies in the need to preserve and record the original characteristics of the building, to leave testimony of material keys and a way of life that is part of urban history and culture. In the case of Montevideo, the demolition of tenements-when they were still inhabited-represented the loss of an important cultural heritage and the expulsion of part of that population to the urban peripheries.

Corruption in public procurement remains a challenge to good governance, especially in developing nations. Blockchain technology has been espoused as a new paradigm for achieving sustainable public procurement practices for effective service delivery and, by extension, promoting sustainable development. Given the potential of blockchain technology, its implementation has been slow in developing countries. Additionally, there is an inadequate decision support framework to prioritize corruption-prone stages of the public procurement cycle for strategic blockchain integration at the most critical corruption-prone stages of the public procurement cycle given the scarce resources available in developing countries. Therefore, we employed a matured theory that is the principal-agent theory to identify key agency problems related to public procurement in developing countries. An interview with 25 experts and a thorough review of Ghana's Auditor General produced seven public procurement cycle stages. Further, a survey was designed for experts and stakeholders to prioritize the identified procurement stages under the agency problems through the Analytic Hierarchy Process (AHP). Our results revealed that tender evaluation was the most critical stage susceptible to corruption, followed by contract management and procurement planning in the public procurement stages. Additionally, for the relative importance of the criteria, information asymmetry was ranked first, followed by moral hazard, and then adverse selection. This study offers a targeted framework for blockchain deployment in public procurement from an African country perspective. The outcome of this study provides insights for policymakers and procurement practitioners to know the most critical stages of public procurement stages and leverage blockchain technology given the scarcity of resources in developing countries to aid sustainable public procurement. The proposed blockchain framework can enhance service delivery, citizens' trust, and international donor confidence in partnership and funding for public procurement projects in developing countries.

2025, Racic : Rab construction research

Quantity take-off menjadi hal yang sangat krusial karena menjadi dasar perhitungan yang berkelanjutan untuk tahap perencanaan. Quantity take-off digunakan untuk perhitungan BoQ atau estimasi biaya. Kesalahan dalam memperkirakan quantity take-off akan menyebabkan penyimpangan biaya dan atau adanya penyimpangan pada volume kebutuhan material. Diperlukan adanya perhitungan quantity take-off dan rencana anggaran biaya (RAB) yang efektif yang dapat dilakukan dengan metode BIM 5D. Penerapan konsep BIM memudahkan dalam ekstraksi quantity take-off langsung dari model 3D hingga kemudian terintegrasi dalam pengolahan estimasi biaya. Penelitian ini bertujuan untuk mendapatkan estimasi biaya dengan menerapkan konsep BIM 5D. Menggunakan bantuan software PriMus untuk membuat AHSP dan PriMus IFC untuk ekstraksi quantity take-off. Hasil yang didapatkan dari penelitian ini, bahwa dengan menggunakan konsep BIM 5D estimasi biaya yang dihasilkan terdapat selisih sebesar 7% lebih kecil dari anggaran biaya rencana awal. Hal tersebut terjadi dikarenakan perbedaan detail perhitungan volume pada perencanaan awal secara konvensional yang dihasilkan, serta beberapa diantaranya disebabkan karena data dari perencanaan modeling tidak memodelkan semua elemen konstruksi, yang kemudian muncul tanggung jawab berkelanjutan atas masalah tersebut oleh BIM modeler. Implementasi konsep BIM 5D dapat meningkatkan komunikasi, kolaborasi, dan menciptakan komitmen atau tanggung jawab yang berkelanjutan sehingga proses pengambilan keputusan menjadi lebih cepat dan tepat.

Resumo O BIM vem sendo um termo popular no Brasil, desde a criação da Estratégia BIM BR em abril de 2020, principalmente em contratações públicas. Entretando, mesmo a metodologia sendo um grande potencial para o Brasil, seu uso em obras de infraestrutura é um atual desafio. Pela grande demanda e alto nível de investimento, o BIM ainda é um gargalo para discussões, principalmente no âmbito governamental. Nestas circunstâncias, há uma lacuna na existência de normativos específicos para definição do nível detalhamento e informações que abrangem projetos BIM. Este artigo traz especificações para elaboração de projetos BIM em pontes e viadutos, propõe nova caracterização de nível de detalhamento (LOD) adequadas às etapas de contratações públicas frente a leis brasileiras e, sugere um checklist para verificação das entregas dos ativos. O trabalho utilizou-se da metodologia de pesquisa Design Science Research (DSR), onde realizou-se um apanhado de publicações normativas, trabalhos acadêmicos e propostas técnicas internacionais. As revisões literárias foram aplicadas em procedimentos do Departamento Nacional de Infraestrutura de Transportes (DNIT) e VALEC S/A para validação de cada método em todas as fases de projeto, adaptando-os para o cenário nacional. Durante a transposição das informações dos projetos escolhidos como estudo de caso, foram encontradas dificuldades esperadas devido à transposição de informações nos projetos. Todavia, a etapa de validação prática permitiu adequar as propostas abordadas e chegou-se em uma linguagem única para a minuta de um normativo.

O processo de quantificação e orçamentação de projetos de engenharia pode ser otimizado com a adoção da Modelagem da Informação da Construção (BIM). Obras rodoviárias são constituídas de diversas disciplinas, onde a extração das quantidades do modelo de forma automatizada facilita a elaboração de orçamentos. Esta pesquisa busca desenvolver um fluxo de trabalho para quantificação e orçamentação em BIM com o mapeamento das informações necessárias para pavimentação e terraplenagem. Dessa forma, foi proposto um fluxo de trabalho com as etapas: i) definição dos requisitos para orçamento; ii) modelagem do estudo de caso; iii) extração de quantidades; iv) elaboração do orçamento em BIM. A modelagem do estudo de caso foi realizada no Autodesk Civil 3D com a configuração personalizada de conjuntos de propriedades. Os quantitativos de terraplenagem foram extraídos do modelo como relatórios por seção. O serviço de limpeza do terreno foi quantificado com o deslocamento da superfície existente. As distâncias de transporte foram estimadas com base em jazidas próximas da obra. As camadas de pavimentação foram quantificadas pelo Civil 3D conforme os códigos das camadas. Os dados foram importados na plataforma OrçaFascio, o que possibilitou o mapeamento das informações necessárias do modelo. Foram notadas dificuldades na avaliação da acurácia geométrica dos modelos e na extração automática de quantitativos, o que exige padronização de dados. Os resultados obtidos evidenciam a importância da definição de requisitos, de forma que o modelo seja elaborado atendendo os padrões e os formatos das ferramentas de orçamentação. Recomenda-se a modelagem em outras soluções do mercado, além da adoção de formatos abertos e de rotinas para tornar o processo mais dinâmico.

Acute or chronic poisoning by drugs, illicit substances, environmental agents can cause seizures with a variable incidence. Seizures may be explained by the intrinsic properties of the drug or toxic agent. Among drugs, the incidence of tricyclic antidepressants induced seizures was particularly high. The increasing use of psychostimulants, like cocaine, is also responsible for frequent seizures. Drug induced seizures are usually brief, single, generalized tonic–clonic and self-limiting. They can even stop before any drug administration. However, they may evolve in some instances to status epilepticus. The mechanisms involved in drug induced seizures are rather similar to those observed in epileptic seizures.Yet, more specific mechanisms are also encountered and they will modify the therapeutic decisions. Also, extraneurological disorders could worsen the clinical condition. Several complications are described, including cardiocirculatory failure. © 2004 Société de réanimation de lan...

This paper outlined the information of Radio frequency identification technology in tracking the tool in the construction jobsite. Tool accessibility is very important in the productivity of construction team. This research has developed to improve the efficiency of tracking tool and to study the system of storing operational and maintenance data by using radio frequency identification technology. This paper demonstrated that active radio frequency identification technology can be used to track the small tool and storing the operation and maintenance data on the tools in the construction site despite metal inference and low temperature. The methodology includes the involvement of two electrical construction firms; the technique is experimented on many construction job sites. Economics, lack of up gradation, lack of vision and range data from the tally were recognised as the most significant factors limiting radio frequency identification commercialization for tool tracking.

Durante la edad media, el Estado y sus agentes controlaban la vida y pensamiento de Los ciudadanos a quienes llamaban los siervos del señor. Era un oprobio para el gobierno, divinizado, que las personas pensaran y actuaran por sí mismos. Todo avance científico y tecnológico que no fuese controlado por el gobierno era frenado por el Estado. De no ser por personalidades que enfrentaron la actitud irrazonable e inmantenible de funcionarios públicos medievales, aun seguiríamos viviendo en una tierra plana.

2025, Construction 4.0- An innnovation Platform for the Built Environment

Presenting a background on diffusion of innovation in the AEC industry and an expanded discussion on factors hindering and motivating innovation highlighting the clash between fragmentation and integration.  Correlating a revised categorization of 4.0 concepts and technologies discussed in previous chapters in terms of their corresponding stage of diffusion across all project phases.  Discussing how technological advancements revealed opportunities for novel and more collaborative project delivery methods such as IPD (Integrated Project Delivery), and how this has the potential to speed up integral 4.0 innovations in a reciprocal feedback manner.  Introducing a broad vision on revising the design and construction curricula to allow for more cross-disciplinary information flow from disciplines that are traditionally left out from training and practice.  Suggest future directions both in industry and academia for introducing interdisciplinary research methods which will allow engineers to take the leadership back in developing their own design and engineering tools (from software engineers) that will allow them to lead the AEC in the information age.

2025, Building Simulation Conference Proceedings

Data management has been one of the most interesting research fields within the smart city framework over the last years, with the aim of optimizing energy saving at district level. This topic involves the creation of a 3D city model considering heterogeneous datasets, such as Building Information Models (BIMs), Geographical Information Systems (GISs) and System Information Models (SIMs), taking into account both buildings and the energy network. Through the creation of a common platform, the data sharing was allowed starting from the needs of the users, such as the public administrator, the building manager and the energy professional. For this reason, the development of a District Information Modelling (DIM) methodology for the data management, related to the energy saving and CO2 emission, is considered the focus of this paper. It also presents a specific tool developed for the comparison of energy data in a selected district: the Benchmarking Tool.

In recent years, the research about energy waste and CO2 emission reduction has gained a strong momentum, also pushed by European and national funding initiatives. The main purpose of this large effort is to reduce the effects of greenhouse emission, climate change to head for a sustainable society. In this scenario, Information and Communication Technologies (ICT) play a key role. From one side, advances in physical and environmental information sensing, communication and processing, enabled the monitoring of energy behaviour of buildings in real-time. The access to this information has been made easy and ubiquitous thank to Internet-of-Things (IoT) devices and protocols. From the other side, the creation of digital repositories of buildings and districts (i.e. Building Information Models -BIM) enabled the development of complex and rich energy models that can be used for simulation and prediction purposes. As such, an opportunity is emerging of mixing these two information categories to either create better models and to detect unwanted or inefficient energy behaviours. In this paper, we present a software architecture for management and simulation of energy behaviours in buildings that integrates heterogeneous data such as BIM, IoT, GIS (Geographical Information System) and meteorological services. This integration allows: i) (near-) real-time visualisation of energy consumption information in the building context and ii) building performance evaluation through energy modelling and simulation exploiting data from the field and real weather conditions. Finally, we discuss the experimental results obtained in a real-world case-study.

In the manufacturing sector, data has become a strategic asset, driving innovation and operational excellence. However, the increasing digitalization of processes introduces significant risks, particularly concerning the protection of intellectual property (IP) and the assurance of data integrity. This paper examines the critical role of data governance in addressing these challenges, emphasizing the need for robust policies, advanced technologies, and cultural alignment. By safeguarding proprietary designs and operational data through access control, encryption, and traceability tools, manufacturers can mitigate the risk of IP theft and unauthorized access. Simultaneously, implementing rigorous data quality and lineage practices ensures accurate, consistent, and reliable information for decision-making. Effective data governance enables manufacturers to not only protect their competitive advantage but also comply with regulatory standards, foster collaboration, and drive sustained growth in an increasingly interconnected world.

Building Information Modeling (BIM) is a process that uses three-dimensional (3D) models to represent a building's design, construction, and operation. BIM has the potential to revolutionize the facility management (FM) industry by providing FM professionals with a more comprehensive and accurate view of the building. This paper examines the awareness and utilization of BIM in FM companies in the Federal Capital Territory (FCT) of Abuja, Nigeria. The study used quantitative design and data were collected through questionnaire survey from real estate professionals, the study adopted purposive simple random sampling technique and SPSS software version 22 was used for data analysis and the results were presented in tables. The study found that there is a low level of awareness and utilization of BIM among FM companies in Abuja. The paper also found that there are a number of barriers to the adoption of BIM in FM practices, including lack of awareness of the benefits of BIM, lack of training and expertise in BIM, concerns about the security and compatibility of BIM data. The paper concludes that there is a need to increase awareness of the benefits of BIM among FM professionals in Abuja. The study also recommends that FM companies in Abuja invest in training and expertise in BIM, and that the government provide financial support for the adoption of BIM in FM practices. The paper also found that BIM can be beneficial to FM practices in a number of ways, including improved communication and collaboration between FM professionals and other stakeholders, increased efficiency in FM tasks such as preventive maintenance and asset management, reduced risk of errors and omissions, improved decision-making, increased sustainability of buildings and that BIM has the potential to revolutionize the FM industry in Abuja. However, there is a need to increase awareness of the benefits of BIM and to address the barriers to its adoption.

The design communication is gradually being changed from 2D based to integrated 3D digital interface. Building Information Modeling (BIM) is a modelbased design concept, in which buildings will be built virtually before they get built out in the field, where data models organized for complete integration of all relevant factors in the building lifecycle which also manages the information exchange between the AEC (Architects, Engineers, Contractors) professionals, to strengthen the interaction between the design team. BIM is a shared knowledge about the information for decisions making during its lifecycle. There’s still much to be learned about the opportunities and implications of this tool. In this project studing BIM appling on existing building, this existing building having G+1 floor with total built up area 158.07 SQM .In this building ground floor having 2BHK and first floor having 2BHK and on terrace floor having attched toilet.

Little doubt exists that technologies for precisely, and automatically measuring energy use are timely. Pressure to reduce greenhouse gas emissions, the potential for a generation shortfall, and rising energy prices, modern building complexities, mean that estimating building energy use patterns, profiling of building energy use, and energy failure mode identification can help to maintain energy efficiency. However, further uses exist beyond operational management; These include urgently required meta-analysis of building stock by sector, up to national stock levels, to inform policymakers, since a dearth of national stock data exists at government level in many countries. Many existing systems use radio telemetry, often producing unclean data. Analysis of energy data for large datasets becomes expensive due to incompatible formats, hampering use of old data on new systems, and data from different systems should we acquire new data, or as we acquire physical buildings. We argue that a standard should include basic specifications for fundamentals such as date formats, but a secondary scalable layer will allow future-proofing of datasets for longitudinal study, and open the door to advanced analysis techniques such as complex event processing. Disaggregation to plant level, as well as building related activities, such as manufacturing activity, also becomes possible with a scalable data structure. This paper, proposes a framework for an energy data standard from a data analysis perspective built around four areas: Temporal, accuracy & precision, operational and energy documentation.
