In light of the issues associated with the laying process of transmission line cables, including concealed security risks and contact collisions between pulleys and cables, which primarily stem from reliance on drawings, this paper introduces a simulation methodology for the cable laying construction process utilizing Building Information Modeling (BIM) technology. Initially, two-dimensional DWG graphic data are employed to develop a model of the target equipment and construction environment using BIM software (Solid works 2020). Subsequently, the cable is accurately modeled by applying ADAMS virtual prototype technology, the bushing force connection method, and the macro command language. This allows for the construction of a three-dimensional real cable laying system for transmission lines, enabling the simulation of the dynamic cable laying process in the field. Subsequently, an error analysis is conducted to compare the axial tension and laying speed of the cable with theoretical calculation values. The study then proceeds to analyze tension fluctuations during the cable laying process and assess the load-bearing capacity of the pulleys, thus facilitating effective control of the construction process and enhancing safety measures. The findings indicate that the proposed method can accurately and efficiently simulate the on-site cable laying construction process, with numerical errors maintained below 5%, thereby validating the integrity of the model. Furthermore, the traction overload safety protection amplification coefficient is determined to be α = 1.5. It is highlighted that the bearing capacity of the block must exceed 60% of the load carried by the conductor at constant speed. This research provides a theoretical foundation for addressing safety hazards in cable laying engineering and holds certain engineering value. [ABSTRACT FROM AUTHOR]

As one of the primary precast components in prefabricated construction, composite slabs have increasingly attracted interest for their costs as well as carbon footprint in production and installation stages. Conventional methods for separating composite slabs can lead to a building project necessitating multiple specifications of composite slabs. Due to the requirement to customize molds for different modulus of composite slabs, the production process experiences a substantial rise in energy consumption and resource waste. This not only increases production complexity and expenses but also indirectly raises carbon emissions. This paper conducts secondary development of a plugin based on the Building Information Modeling (BIM) technology platform, C# language and Visual Studio 2017 to optimize the modular design of composite slabs with the help of Revit software. This plugin can quickly and intelligently recommend the most suitable combination of composite slabs specifications based on the actual size of the floor slabs, thereby greatly reducing the types of composite slabs required. The modular optimization process developed in this paper is applied to an actual engineering project, the results show that the types of composite slabs molds after optimization are reduced from 9 to 4, and the mold cost is reduced by 69.60%. At the same time, the carbon emissions of the optimized composite slabs in the production stage are reduced by 7.03% compared with those before optimization. It is observed that this optimization scheme not only significantly reduces the production costs of composite slabs and improves production efficiency but also effectively reduces carbon emissions during the production phase of composite slabs.

Architecture is a science that studies designing a building by applying 3 principles, namely strength, function, and beauty. A building generally consists of a form or pattern in the form of 2 dimensions, for example, the floor plane, the ceiling plane, and others, and the shape/form consists of the shape/shape of a volume (3 dimensions), for example, the space in the building. In designing a building, an architect who is an expert in the field of architecture is needed. This study uses a descriptive method to find out how to make design drawing documents by utilizing BIM technology, AutoCAD software, and SketchUp. The results show that BIM technology, AutoCAD software, and Sketch can produce architectural design drawings more efficiently in terms of time, and cost and produce more accurate image quality. From the explanation above, it can be concluded that the results show that the use of BIM technology, AutoCAD software, and sketch-up in architectural design can produce architectural design drawings more efficiently in terms of time, and cost and produce more accurate image quality.

In China’s new urbanization, urban rail transit has developed rapidly. Multiline subway stations in Chongqing face issues such as high passenger flow and intersecting pedestrian flows, leading to congestion, which affects station safety and service quality. This study aims to optimize subway station architectural flow lines, defined as pathways facilitating pedestrian movement within stations, to meet passenger demands, improve service quality, and contribute to smart city development. Combining BIM technology with pedestrian simulation, this research uses quantitative data analysis to optimize subway station flow lines under non-emergency conditions, a scenario rarely addressed in existing studies that focus on emergency evacuations, and proposes optimization strategies. We constructed an optimization framework based on BIM and pedestrian simulation and conducted an empirical study at Chongqing Ranjiaba Station to verify its feasibility. This research systematically examines subway station entry, exit, and transfer systems through literature reviews, surveys, simulations, and case studies. The analysis, within the context of smart city development and transit-oriented design, identifies issues in station layout and pedestrian flow, proposing and validating optimized design schemes. The study introduces a BIM-based framework for optimizing subway station flow lines, demonstrating improvements in pedestrian safety, operational efficiency, and user experience, offering practical solutions.

Methods: This paper takes the housing project in District A of Guangzhou as the research object, and uses BIM technology to design the precast part of the reinforced concrete structure in the C household, including the deepening design of the reinforced concrete structure, production management of the precast components, tracking, address data modeling, hoisting and deployment, etc., which penetrates into all aspects of the design of the reinforced concrete structure. It was found that after the application of BIM technology, the construction period was reduced from the originally established 13 days per floor to 7 days per floor, and the on-site construction errors were reduced, the construction efficiency and construction quality were improved, and the project was successfully completed. It can be seen that the application of BIM technology in the design of reinforced concrete structures in urban buildings can shorten the construction period and ensure the construction quality at the same time. It is a favorable means to promote the development of urban construction industry and should be actively promoted.

In recent years, the development of prefabricated buildings has been significantly promoted by China's policy initiatives focusing on innovation, green development, and industrialization in the construction sector. This paper explores the application of Building Information Modeling (BIM) collaborative design technology in the construction of intelligent buildings with prefabricated steel structures. Using the Zhangjiawo Sports Park Project as a case study, we detail the integration of digital design, industrial production, and intelligent construction methodologies. The project leverages BIM for precise modeling (LOD400), optimizing construction through collision analysis, and enhancing natural lighting and ventilation via simulation tools. The prefabrication process employs advanced steel structure manufacturing techniques and intelligent logistics, while on-site construction utilizes automated systems, such as ALC wall panel installation robots. These innovations not only improve construction efficiency and safety but also align with national low-carbon and sustainable development goals. The findings provide valuable insights into the benefits and implementation strategies of BIM and intelligent construction technologies in prefabricated building projects. [ABSTRACT FROM AUTHOR]

Entering the 21st century, with the acceleration of economic globalization, urban development is facing many challenges such as population growth, resource scarcity, and environmental pressure. Therefore, underground engineering construction has received widespread attention. The application of Wireless Sensing Network (WSN) technology in civil engineering structural monitoring meets the intelligent monitoring needs of tunnel construction and solves the problem of construction safety monitoring. This study combines statistical analysis, theoretical research, numerical simulation, BIM technology, and on-site verification methods to systematically explore the perception and visualization management of safety risks in subway construction. The application of wireless monitoring technology has verified the monitoring effect of wireless laser ranging and wireless inclination sensors during the construction period. The results show that under timely support conditions, the tunnel structure remains basically safe. For weak stratum tunnels, numerical simulation and backward advanced deep hole grouting pre reinforcement technology are studied to ensure the stability of the soil layer around the tunnel. At the same time, BIM technology is used to construct a tunnel model, visualize the construction process, and develop an intelligent sensing control system for real-time monitoring and risk warning.

With the acceleration of urbanization, we are paying more and more attention to the safety and reliability of building water supply and drainage systems. Faced with various limitations of traditional monitoring methods, such as insufficient real-time performance and difficulties in data collection, we propose a new solution that combines BIM (Building Information Modeling) technology and the Internet of Things. This system not only enables real-time monitoring, but also quickly addresses security risks, greatly improving management efficiency and system security. In terms of system stability, the standard deviation of water pressure based on BIM technology is 1.1 kPa and the standard deviation of water flow rate is 0.2 L/s. Moreover, the building water supply and drainage network security monitoring project based on BIM technology can quickly and accurately respond to various security incidents. From the data conclusion, it can be seen that the system based on BIM technology has efficient, accurate, stable, and secure monitoring capabilities. [ABSTRACT FROM AUTHOR]

BIM technology is a design approach recommended by EU directives that started to gain momentum in the years 2012–2014. This technology enables the user to create building plans and designs more quickly while avoiding many errors. In addition, by entering certain data into BIM models, it is easier to complete consecutive steps connected to the construction, use and demolition of buildings. It has also been noticed that BIM is not as popular in practice as it might appear, despite the many unquestionable benefits arising from its application. This article presents the results of a study of barriers that have constrained the development of BIM technology in recent years all over the world. The strength of factors defined on the basis of the literature was assessed. The analyses were carried out using the author's own evaluation method, which allowed the power of the most important barriers to be assessed. This study shows that financial barriers, mentioned by many authors as the most important factor, still remain a serious problem, and their strength is the highest among the analyzed barriers. Barriers associated with the shortage of knowledge and specialists also feature prominently in assessments, and their importance continues to display a tendency to increase. [ABSTRACT FROM AUTHOR]

This article explores multi-work area management during pile foundation drilling using a BIM parameterized model, focusing on informatization. The results indicate the following: (i) A dynamic zoning method for pile foundation construction using BIM models was developed to support information management systems and address resource allocation challenges amid dynamic construction team changes. (ii) Adaptive zoning methods were proposed, incorporating the dynamic adjustment of construction work areas, including the division of virtual work areas and adaptive adjustment of pile foundation partition parameters. (iii) Work area modeling and zoning were applied on site, with pile foundation modeling aligning with engineering design distribution, and work area zoning accurately reflecting the on-site construction status. (iv) This method enables adaptive synchronization between pile foundation model attributes and work area information, integrating zoning management into the information system to enhance the construction unit's information management system and digital management level.

With the high-quality development of transportation in China, highway bridges, as the core part of transportation infrastructure, have received widespread attention for their safety and operation management. Especially in the field of super large bridges, due to their importance in transportation and enormous social benefits, safety and operation management are particularly crucial. This research focused on the operation and maintenance management of super large bridges, especially how to improve the efficiency and effectiveness of bridge operation and maintenance management through BIM (Building Information Modeling) technology. This technology deepened the understanding of bridge structure and performance by establishing a detailed BIM model. By standardizing model data and establishing coding systems, data interoperability and management efficiency were improved, providing decision support for the daily management and maintenance of bridges. According to experimental data, it can be concluded that the accuracy of basic information judgment, temperature and humidity accuracy, bridge status judgment accuracy, and operation and maintenance information accuracy of BIM dynamic temperature recognition and maintenance technology for bridges were among four sets of data. The accuracy rates of all four data items were between 91.20% and 94.27%, indicating a high accuracy rate. The comprehensive application of these technologies aims to improve the operation and maintenance management level of super large bridges, ensure their long-term stability and safety, and contribute to the sustainable development of transportation systems.

In the wave of the digital era, Building Information Modelling (BIM) has emerged as the primary tool for intelligent construction and digital transformation in the Architecture, Engineering, and Construction (AEC) industry. China's focus on policy guidance for the dissemination and application of BIM technology has promoted high-quality development and technological innovation in the AEC industry. However, few studies have described the multi-dimensional evolution picture of BIM technology policy in China, and lack of effective grasp and prediction of policy evolution law and future direction. An improved policy quantitative analysis framework is built using natural language processing (NLP) based on deep learning in this paper. The dynamic characteristics of 242 Chinese BIM technology policy documents from 1998 to 2022 in the PKULAW database are quantitatively analyzed by the framework, and the four-stage integrated evolution of Chinese BIM technology policy is quantitatively mapped in a visual form through network analysis and dynamic topic model (DTM). Furthermore, this research conducts a comprehensive discussion from three dimensions, providing valuable insights for policy makers and industry participants in China. The findings contribute to the deep integration of policy optimization and the construction industry, while also aiming to share China's experience in BIM technology governance with other countries and regions. Ultimately, this study seeks to support the global AEC industry in its digital transformation and development by offering valuable knowledge and perspectives. [ABSTRACT FROM AUTHOR]

The Ningbo International Conference Center Project incorporates elements of Chinese traditional culture into its architectural style, resulting in the world's first cantilever bridge international conference center. During the construction process, it faced challenges such as complex engineering geological environments and diverse architectural styles. By harnessing building information modeling (BIM) technology, many challenges encompassing intricate environmental conditions, architectural structures, and construction complexities are effectively visualized in three dimensions, thereby offering viable solutions for engineering implementation. In the scheme design stage, BIM technology plays a pivotal role in bridging the gap between design and construction, optimizing engineering pile and wall material designs. During the deepening design stage, BIM aids in refining designs through intricate node optimization for the ultralong comb type inclined water panel curtain wall and glued wood column decoration, thereby enhancing construction efficiency. Additionally, BIM technology has also played an important role in the simulation and scheme analysis of the entire construction process of complex steel structures. Through the implementation of BIM technology, numerous challenges encountered during the construction phase of the Ningbo International Conference Center project have been effectively resolved, which serves as a valuable reference for employing BIM technology in large-scale international conference center projects.

The pre-tender cost estimation serves as the foundation for determining the project cost in the early stages and is crucial for all parties involved in the tendering process. It is expected to be highly accurate. However, industry surveys have advocated that in the Iranian construction industry, the pre-tender estimated costs of construction projects are not sufficiently accurate during the bidding stage. Building information modelling (BIM) technology is a modern digital tool deployed in the construction industry that has seen substantial growth of application. It employs useful tools in different sectors and has extended its involvement in various stages of the project lifecycle, including feasibility studies, planning, design, construction, and operation and maintenance. This study examines and assesses the status of BIM development in Iran for its applicability in the pre-tender cost estimating process in construction projects. The findings of this study indicate that while there is a limited number of Iranian building projects' BIM models that possess the required quality and capabilities for BIM-based cost estimation, the results obtained are more precise when compared to existing manual methods. Additionally, utilising BIM-based cost estimation significantly reduces the time required for this process by enhancing the speed of cost estimation operations. An innovative evaluation framework for assessing the quality and functionalities of BIM models is presented, which improves the accuracy of cost estimation before the bidding process in Iran's construction industry. The research findings demonstrate the enhanced accuracy and effectiveness of BIM as compared to conventional approaches. It also suggests the incorporation of AI technology for model evaluation, which has the potential to become an established global industry standard. [ABSTRACT FROM AUTHOR]

The complexity of the wharf components and the harshness of the offshore construction environment increase the safety risk of hazards, which has highlighted the importance and urgency of safety risk management in high-pile wharf constructions. This paper established a visualized digital construction safety risk model for high-pile wharf based on a so-called FAHP method (the combination of fuzzy comprehensive evaluation (FCE) and analytic hierarchy process (AHP) methods). The construction safety risk indicators were constructed as the target layer, the principle layer and the scheme layer, and then the corresponding safety risk assessment algorithm was established. The physical, functional and safety risk assessment parameters of the component in the BIM model were employed to the safety risk assessment algorithm, and the risk assessment level of each sub-process was subsequently classified. The case study indicated that the high-pile wharf construction project included five elements in principle layer and 15 risk indicators in the scheme layer. Moreover, it was demonstrated that the sub-processes with the highest construction risk level were steel pipe pile sinking in wharf construction and steel pipe pile, steel sheath-immersed pile sinking and embedded rock pile construction in approaches to bridge construction with a risk level of III. In this way, the quantitative visualization of the construction safety risk was effectively realized, which facilitates the safety risk management of construction sites and timely warning and response to unexpected safety accidents.
