Abstract:
Engineering mapping can not only assist engineers to find scheduling and quality problems, but also provide data basis to conduct further engineering analysis. Compared with traditional engineering surveying and mapping technology, UAV low altitude photogrammetry technology has the advantages of simple operation, good economy, and strong mobility. Accordingly, in this paper, UAV photography technology is being introduced into civil engineering, and the issue of its route planning is being discussed to achieve the three-dimensional real scene modeling of the site. In terms of the modelling problems, this paper divides the original site into proper zones and simplifies the route planning problem to a full coverage path planning problem under the irregular field, where obstacle avoidance planning does not need to be considered. Methodologically, the combination of A*Algorithm and BINN algorithm have solved the problem of "dead zone" in BINN algorithm, and the setting of constraint rules has solved the problem of random walk in the initial stage of the algorithm.Finally, by taking an actual earthwork project as an example, the feasibility of the improved algorithm is being proved.

Abstract:
The construction site is a complex and changeable working environment with a high accident rate. There are multiple hazardous areas on the same engineering site. The traditional management method for this area is to send full-time personnel to guard and manage. This manual management method is prone to errors and cannot timely detect the entry of personnel in time.For dynamic hazardous areas, operators must take consideration of the surrounding environment while operating the machinery, which will not only reduce work efficiency but also be unfavorable for finding workers in the area. In order to solve this problem and to improve the efficiency of supervision, the integration of computer vision will be a good choice. This method first needs to determine the hazardous area according to relevant rules and regulations, then arrange the camera at the appropriate position, and finally use the YOLOv3(You Only Look Once, is a fast and accurate real-time object detection algorithm, developed to YOLOv3 to achieve a breakthrough in the algorithm, and also achieved a qualitative leap in accuracy and speed)target recognition algorithm to achieve Intelligent supervision. This article introduces the basic principle of the algorithm and the specific realization method of target recognition, and according to the different scope of the hazardous area, two methods of making training sets are being designed.Finally, experiments are used to verify the feasibility and accuracy of the method. The results show that the method has a higher accuracy rate for worker identification. Therefore, applying this method to worker identification in hazardous areas will greatly reduce the probability of accidents and make up for the shortcomings of purely manual supervision enrich the means of safety management.

Abstract:
In recent years, China has successively developed and renovated many large railway hubs, such as Xiong′an Station, Qinghe Station, Fengtai Station, etc. These stations have been developed from simple train stations to complex city transport hubs, which shows the characteristics of scaled area, integrated function, and diversified shape. Thus, it demands much higher requirements on EPC. How to eliminate the "Information Island" on the construction site through digitalization has become a research direction. Taking Hangzhou West Railway Station as an example, this paper has introduced 4D-BIM technologies and grid management from four aspects, which are, grid management platform system architecture, grid coding, BIM model grid division, and grid construction management process. This shows the efficiencies during the construction of Hangzhou West Railway Station, and also presents the positive impacts to construction schedule, construction quality, and construction safety.

Abstract:
At present, China′s construction industry urgently needs to be developed into industrialization, informatization, and intelligentization. But the serious shortage of integrated talents for pre-cast building and BIM technology has become a bottleneck. In view of the existing shortage for the theory teaching and practice teaching, practice teaching goals of design, production and construction in pre-cast building BIM application were being proposed through the combination of OBE concept and industry demands. By using CDIO engineering education mode and case driven method, practice teaching framework of assembly building integrated BIM technology is being established. Through teaching case analysis and students′feedback, it proves that this practice system can effectively fill the gaps in pre-cast building theory teaching, and significantly improve students′ comprehensive ability to use BIM technology to solve the issues in pre-cast building design, production and construction.

Abstract:
In order to decrease the impact of reservoir or river water on the soaking embankment and to improve its slope stability, special reinforcement is usually taken place in soaking embankment during the design stage. The traditional design is limited in low accuracy and low efficiencies in design. BIM-based parametric workflow is being proposed and filling embankment model-based Dynamo program is being developed according to the conventional design principle of soaking embankment. By using the Huanhu Road Project (Phase Ⅱ) in Chongqing Liangjiang Collaborative Innovation Zone as case scenario, the proposed technical route and design method are being validated. The parametric design method of soaking embankment can significantly improve the design quality and working efficiency.

Abstract:
As a type of ruled surface, the one-sheet hyperboloid has excellent geometric properties and can also be easily structured by freeform surfaces. As there are not many projects that use one-sheet hyperboloids as the main logic modeling in architectural design, the Hangzhou Future Park(Qingting Park)project is an eye-catching project that mainly uses one-sheet hyperboloid as the architectural shape. This article introduces the key processes and experience of architectural modeling in this project, and summarizes a set of practical solutions including the selection of geometric prototypes, the optimization of modeling logic, and the parametric design of facades.

Abstract:
In order to realize the control and management of steel structure and power equipment in the substation engineering construction, it is necessary to identify the relevant information from the title bar of a large number of steel structure drawings, and subsequently contrast them with the real structures. To deal with the blurriness of word, diversity of table and confusion of information, a deep learning method combining the CNN+RNN text detection model and the CRNN character recognition model is being proposed. Carrying out the detection and recognition experiments in the existing data set of steel structures, the detection precision reaches over 80% and the recognition accuracy reaches over 90%, which is superior to other detection and recognition methods. The results of the engineering application show that this method can effectively reduce the difficulty in feature extraction caused by the differences in arrangement, size, font and color of text, which can improve the accuracy of text recognition in title bar of steel structure drawings of substations.

Therefore, based on the kindergarten project of Sanya Nanfan Science and Technology City Primary School, this paper will study and discuss the application of BIM Technology in the design and construction stage of school construction project. Among them, the project model being quickly built based on BIM series software is mainly used for design delivery, spatial vision analysis, comprehensive coordination, clear height spatial analysis and calculation, deepening design, BIM drawing, and other applications in project design and construction stage, so as to effectively improve the process and benefits of school projects, and to provide the valuable experience reference for similar school projects in the future.

Abstract:
In the process of large-scale project construction, BIM technology is being increasingly introduced and applied. Combining government documents regarding to quality and safety with BIM technology, this paper has clarified the system of supervision, the content of supervision, and the way of supervision under BIM mode. This paper has adopted a specific scenario to make the evaluation regarding to the outcome. It shows the results from all the application points are meeting with the expectations, which can satisfy the daily government supervision and can optimizing the workflow for improving the work efficiencies through the transformation.
