Abstract:
The present paper applies knowledge graph technology to design compliance checking, and proposes an Automatic Compliance Checking (ACC) system based on standard knowledge graph. Through analyzing Chinese standards and structural design rules (hereinafter collectively referred to as standards), the atomic structure of knowledge graph for the minimum semantic unit is created, and some rules for linking the atomic structures are developed, thus establishing a method for constructing a building standard knowledge graph (BSKG) with the atomic structure as basic-element. By applying data from the graph to the data-driven code generation module, the executable codes for both information retrieval and compliance checking can be automatically generated, thus enabling BIM model's compliance checking to be automatically conducted.

Abstract:
In recent years, carbon peaking and carbon neutrality goals have been big concerns. However, as a major player in energy consumption and pollution emissions, the construction industry's development of traditional ways is contradictory to the overall national development goals. Therefore, technology reform in the construction industry is heavily required. The BIM technology has the characteristics of large information carrying capacity and high interaction efficiency, which can be fully applied to solve this problem. However, previous researches have generally been relatively cumbersome and prone to losing a large amount of information, hence the results of previous researches are inaccurate. This paper aims to develop an efficient carbon emission measurement software through the secondary development of Revit software using the C # programming language and the Revit API interface. By establishing a coding library for building materials and construction machinery information and using existing carbon emission factor databases, in-depth analysis is conducted on the carbon emissions generated during the construction phase. The results indicate that the carbon emissions generated during the production stage of building materials are the highest in the physical and chemical stage, and can be almost negligible during the construction stage. The software developed in this paper is easy to operate and has relatively complete functions, which is a positive exploration of China's Green Development.

Abstract:
Jingtianlutu is the first BIM software for highway engineering in domestic transportation industry. Addressing the issue of the software's inability to quickly analyze the bearing capacity of multi-layered geological bodies, an interface program between Jingtianlutu and the common bearing capacity analysis software FLAC3D was developed using the C# language on the Visual Studio 2019 platform, based on the 3D WinForms control Eyeshot. The interface program has a graphical display interface, which can read the terrain data of multi-layered geological bodies from the Jingtianlutu, and layer the geological bodies according to the geological survey data, and obtain the geometry data and material properties of each stratum. The finite element mesh model is automatically created in ANSYS using the APDL command flow. Utilizing the FLAC3D command flow, the pre-processing tasks such as reading and converting mesh models, defining material properties and boundary conditions are automatically completed before the solution process begins. Commonly used analysis results are then automatically exported and sent back to Jingtianlutu. This study provides detailed information on the research and implementation ideas, development tools, development processes, and key algorithms of the interface program. An example is used to verify the interface program, demonstrating that the analysis results of the bearing capacity of multi-layered geological bodies using the interface program are consistent with the results obtained through direct use of ANSYS modeling and FLAC3D calculation. However, the former takes approximately 2 minutes, while the latter takes around 0.6 hours, which significantly enhances the efficiency of designers.

Secondly, Rhino software was used to pick up the key data and correct the deviation, then parametric models of the fixture, steel bar, and surface of the track were created and optimized to solve the problem of track fixture installation positioning and internal surface flatness control. Finally, the three-dimensional laser scanning technology was used to dynamically control the track surface smoothness, which effectively guaranteed the construction quality of the project.

Abstract:
Currently, designers typically rely on their design experience to create building shapes and structures. However, designing the shape of a unique and complex venue can be challenging. Traditional design methods are often time-consuming and require a significant amount of resources, and may not effectively address the complex issues that arise when designing irregular venue structures. This paper focuses on a special-shaped space structure as the research subject, utilizing parametric technology to design the structure. The BIM design concept is integrated into the design process to solve structural selection and analysis problems. A parametric model of the structure is established using Grasshopper. In this process, Abaqus is used to calculate, analyze, and optimize the structural mechanical properties of the model. Finally, a three-dimensional model application is created using BIM software, which can provide new ideas and methods for structural engineers to solve the design challenges of special-shaped space structures.

Abstract:
Introducing digital tools in the construction sector to establish a quantified evaluation and optimization mechanism is crucial for promoting the development of green buildings, reducing carbon emissions, enhancing the quality of construction projects, and driving high-quality development in the construction industry. Taking the example of the research on the full life cycle assessment of green buildings on Guangyang Island in Chongqing, a "BIM Evaluation Matrix Method" is proposed based on the latest national standard system for green buildings, with a BIM model base established. By combining various evaluation control factors in the standards, a preliminary assessment of the project's BIM model's specific simulation verification indicators is conducted. Through continuous optimization and re-verification of the control factors at different stages, the project ultimately meet the requirements for a three-star green building, achieving green building assessment through digital means. The application of the "BIM Evaluation Matrix Method" has improved the overall performance of buildings, providing a more comfortable environment, reducing the impact on the ecological environment, and achieving goals of land conservation, material conservation, energy conservation, water conservation, and sustainable development.

Abstract:
With the development of digitalization and industrialization in Chinese construction industry, the demand for MBD technology in the industry is increasing. However, in the workflow before the generation of this technology, the data integration framework of design, simulation and manufacture are far from perfection, and it is hard to meet the demands of actual architectural engineering programs. At this stage, BIM technology lacks methods and standards for MBD. Even if the design process adopts the full 3D design calculation method, it still needs to be converted to 2D paper for manufacture, which makes little difference and advancement compared with traditional design process. Therefore, this paper focuses on the research and application prospect of MBD technology in the construction industry of China, including the introduction on the development history of MBD technology, the framework building of corresponding marking standards and the potential direction of further application, which is expected to provide some basic theoretical support and technical assistance for the lifecycle management (PLM) of the products, and new ideas for the development of Chinese construction industry.

Abstract:
Studying on the current two-dimensional and three-dimensional parallel design environment of urban rail transit engineering, this paper analyzes the current situation and problems faced in the application and management of BIM technology. What's more, this paper proposes a way of unified management by the constructor-led and the overall design unit, and develops a digital management platform based on cloud technology, which is proved by practice. Based on the digital management platform, the digital management platform can effectively achieve the integrated collaborative design and management of two-dimensional and three-dimensional aspects in rail transit engineering, which is helpful to promote the transformation from two-dimensional design to three-dimensional design, and has certain promotion value.

Abstract:
Building information modeling (BIM) has a strong knowledge system including core theories and the use of representative software. Various platforms and knowledge resources related to BIM are explored in this paper by using the two educational integration modes of the Internet and industry-university collaboration as examples. BIM theory, software application, case analysis, integration of professional courses, skill training, discipline competition, and other aspects are applied to develop the knowledge structure and specific contents, and all types of resources are systematically integrated into the BIM overall framework. Building a whole knowledge system and reflecting the progressive implementation concept from theory to practice, and practice to comprehensive application will improve BIM's professional integration degree and deeper learning and application.

Abstract:
As the main venue of the 81st World Science Fiction Convention, Chengdu Science Museum was designed by Zaha Hadid's team, and the scheme integrates numerous cultural elements e.g., "nebula, Sanxingdui gold mask, and the eye of ancient Shu". The exterior of the building resembles an oriental star island floating in space. The whole building is distorted, and the application of BIM technology ensures the quality of the design and construction of the project. Through the application of BIM visualization, BIM parameterization and other technologies, the difficult points of complex building shape and multiple construction processes have been solved decently. The successful application of BIM technology in Chengdu Science Museum has enhanced the added value of BIM technology in the curtain wall industry, expanded the breadth of BIM technology application, which demonstrates the direction for the application of BIM technology in future special-shaped venues design.

Abstract:
At present, traditional processing and installation methods are mostly adopted in ventilation project construction. However, the overall quality of installation is not only affected by scattered location, but also susceptible to artificially technical ability. The semi-finished products and finished products are prone to quality problems by low processing production efficiency and non-uniform accuracy, what's more, placing points position in installation process is not accurate, which results in deviation. This paper studies on 13 metro stations in Kunming Metro Line 4, and elaborates the air duct processing and installation by using CNC machining equipment, robot wiring equipment and linking data from BIM model. With the aid of the integrated approaches and informationization, the project construction aims to automation, standardization, improving the efficiency and accuracy of air duct processing and installation and improving the system of industalization, meanwhile, as well as reducing labor costs and material loss. By integrating BIM technology with the prefabrication and intelligent installation of ductwork, it can accelerate the overall construction progress of ventilation projects and further enhance the quality of the project.
