Abstract:
Due to the influence of printing materials, printing equipment, printing process and environmental conditions, it is difficult to control the quality of 3D concrete printing, and the common manual inspection is inefficient. Therefore, it is urgent to seek new inspection means. Machine vision technology, as a non-contact detection method, has gradually been applied in 3D concrete printing defect detection. To this end, this paper reviews the research status of machine vision technology in 3D concrete printing defect detection from three aspects: geometry and accuracy of 3D concrete printing, interlayer deformation and stability, and surface defects, which could provide reference for 3D concrete printing quality control and its development.

Abstract:
Based on the concept of the life cycle, this paper integrates static data (e.g. the initial design information of the bridge), and dynamic data (e.g. manual inspection, maintenance records, and real-time monitoring data) to conduct a comprehensive evaluation of cable-stayed bridges from four dimensions of the civil structure includes electromechanical system, ancillary facilities, and operational services, and proposes multi-dimensional evaluation indexes, evaluation process, and calculation methods. Given the shortcomings of the single architecture of the traditional bridge evaluation system, for instance, high system coupling, poor error isolation, and poor scalability, based on the.NET microservice framework, the paper designs and realizes the online comprehensive evaluation system of the cable-stayed bridge by using C# language, middleware technology, and MySQL database. Through the application verification of a cable-stayed bridge in Shanghai, the results show that the evaluation method and system can meet the business needs of bridge evaluation, which can effectively help operating enterprises carry out maintenance analysis.

Abstract:
The traditional tunnel safety early warning methods have some problems, such as the inflexible information transmission, the non-intuitive expression effect and more. Otherwise, the deepening application of BIM Technology in the field of shield tunnel has not been widely valued. To solve these problems, BIM Technology is introduced to realize fast and reliable tunnel structure analysis and safety early warning visualization method. First of all, the model and data transformation between BIM and Finite Element Model (FEM) are realized with the help of socket program and code so that the rapid finite element analysis based on BIM modeling is realized. And then the paper visually displays the structural safety status of calculating structural safety factor by using the visual advantages of BIM, and realizes the tunnel structure safety early warning visualization technology based on BIM and mechanical analysis. The results show that the proposed method of visual expression of safety warning has good effect on tunnel engineering.

Abstract:
Based on BIM technology and green building simulation software, this paper constructs a green building evaluation index system that evaluates buildings and improves and elevates spatial analysis. First of all, according to the relevant regulations in China, the index system combining BIM technology and green building simulation software is determined from the following aspects: safety, durability, health, comfort, convenience, resource saving and livable environment. And then the weight of each index is referred to its score value in relevant standards and the score of experts. Finally, the final green building score was obtained by combining the index score and weighted by layers. The final green building score was divided into four grades from low to high: Unqualified, Level 1, Level 2, and Level 3. From all the efforts above, the paper manages the overall evaluation of green buildings and provides information support for the subsequent green building optimization and transformation. To conclude, the green building evaluation index system based on BIM technology and green building simulation software can evaluate green buildings quickly and effectively. What's more, the green building can improve the space and make the green building effect more remarkable.

Abstract:
This paper focuses on the analysis of building energy consumption and carbon emission indicators according to the requirements of Qingdao's carbon emission BIM review system. The paper found that: firstly, the heating energy consumption and carbon emissions in the operation stage are the largest. There are differences in the proportion of carbon reduction between different enclosure structures. Secondly, the contribution of each factor is as follows: energy efficiency level > carbon emission factor > air conditioning and heating equipment performance > lighting power density > enclosure structures. Intermittent operation of personnel has obvious influence on heating carbon reduction. Thirdly, taking Shinan District of Qingdao as a pilot, Qingdao has developed a special BIM review system for carbon emissions, which can analyze and control carbon emissions of individual buildings and key enterprises, and further help the construction management department control the total amount of regional or urban carbon emissions.

Abstract:
In this paper, a bridge disease detection system based on YOLOv5 algorithm is proposed for UAV bridge disease detection. Firstly, diseases are collected through UAV cruise system. Secondly, K-means clustering algorithm is applied to improve the prior box proportion in YOLOv5 algorithm to obtain the size of bridge disease. Thirdly, the UAV input image is cut to 640 * 640 size by using the image cutting algorithm to reduce the difficulty of model training and reasoning. What's more, this paper uses APAP algorithm to splice the recognition results of cutting images to achieve a complete UAV image recognition result. Finally, the paper employs Python Flask to build an open bridge disease detection Web front-end, which can call the disease weights of different bridge parts according to actual needs, and further realize real-time detection of 13 bridge diseases. The results show that the model can effectively reduce the hardware requirements, directly identify and process UAV images, and achieve rapid disease detection, which is expected to provide an efficient, safe and promising detection method for bridge disease detection.

Abstract:
There are a series of problems in the construction of large-scale stadium: firstly, using BIM design to demonstrate the scheme, visualize decision-making, and solve the coordination among different specialties in the design process; secondly, putting the key issues before the whole construction process to provide convenience for later construction and improve the quality of the project. Taking Shenzhen Sports Center Renovation and Upgrading Project as an example, this paper focuses on the application of BIM technology in the design phase of large stadium, and summarizes a set of effective management methods and processes through the project, which can provide reference for similar projects.

Abstract:
Building information model (BIM) technology is widely used in all kinds of large-scale projects nowadays. Many projects have introduced BIM collaboration platforms for project management, but most of the business functions in the BIM collaboration platform are scarcely used. The reason is that project managers are usually more accustomed to using instant messaging tools e.g. WeChat and nails for daily collaborative work. As a result, the BIM collaboration platform has not played the role of communication and collaboration for the project. This paper introduces a project that adopts the combination of BIM Smart Engineering and Navisworks software, and uses its collaborative office and model integration functions to integrate BIM technology into project management without changing the traditional project management methods, which effectively improving the efficiency and enthusiasm of BIM collaboration. From all the efforts above, a set of BIM integrated coordination management method based on nail platform is formed.
