Abstract:
Specification translation is an important step of BIM compliance checking, and it is also the technical basis and prerequisite for realizing automatic and intelligent code compliance checking. The first step of specification translation is to automatically classify design specifications into predefined categories for preparing the subsequent text analysis and rule extraction. However, due to the lack of corpus in the field of structural design, the automatic classification technology of design specifications needs to be developed. Therefore, based on the "Code for Concrete Structure Design" and "Code for Seismic Design of Buildings", a structural design corpus is created. According to IFC entity name catalog, an automatic classification method of structural design code is proposed by Python language programming and text classification algorithm based on machine learning. The process can be divided into three steps: data preparation and text preprocessing; feature extraction and selection; training, testing and evaluation of classifiers. The results show that the classification method can effectively realize the automatic classification of structural design specifications, and the accuracy and recall rate of the classifier to the test specifications can reach 75%and 83%.

Abstract:
Excavators have broad application scenarios, but in certain hazardous working conditions, using teleoperation is a better option. Meanwhile, with the development of machine vision and deep learning in recent years, a number of algorithms and frameworks for gesture recognition are becoming available. In order to explore the application of MediaPipe-based gesture recognition algorithms in excavator teleoperation, this paper corresponds different hand gestures to different movements of the excavator, and proposes a new control method using hand gestures to achieve excavator teleoperation. The kinematic analysis of the experimental excavation robot was carried out in a laboratory environment, and MediaPipe was used to perform real-time static recognition of 15 gesture types, generate commands and realise the control of the excavator using an Arduino microcontroller. The results show that the system has good performance and can be used for teleoperation control of the excavator, which provides a new form of human-computer interaction for remote control of the excavators.

Abstract:
With the growing of subways, the requirements for managing subway trackside equipment are also increasing. BIM Technology with its information, intelligent characteristics, can be widely used in the project life cycle management. However, when modeling, the commonly used modeling software, Revit, has great limitations in batch creating models and inputting parameter information. Dynamo technology is used to obtain the location information of the equipment in the subway line, and the automatic placement of the equipment is realized according to the location information. Then the corresponding relationship between the engineering information and the equipment is established, and the parameter information is filled in batch. The research results show that: during modeling, the tedious and mechanical work is automatically completed by visual programming language, which can greatly improve the precision and efficiency of modeling, and lay the foundation for the realization of the whole life cycle management of Metro Line trackside equipment.

Abstract:
BIM model is an information carrier that integrates geometric attributes and non geometric attributes of buildings. It can be used to carry all kinds of information of buildings in planning, design, construction, operation, and maintenance, reflecting the characteristics of big data. However, a single BIM model file has limited ability to carry information and data. It is necessary to effectively integrate distributed and extensible web information services with BIM data to solve the problem of massive information bearing and association of BIM model. Through many developments and research, aiming at the key technology of BIM model and web information service, this paper proposes the solution and technical scheme of data mixing through the thinning processing of BIM data and the organization integration with web system.

Abstract:
The steel hyperbolic roof of Hangzhouxi Railway Station is of large volume. The conventional monitoring methods cannot meet the requirements in terms of speed and comprehensiveness. In order to realize high-precision, high-efficiency, and whole process deformation monitoring of Hangzhouxi Railway Station, 3D laser scanning is used to obtain the whole-process point cloud data. The processed point cloud data is registered with the BIM model to analyze the deviation of single component, construction process and morphological structure, so as to realize the whole-process deformation monitoring. The comparison with the measured data of the total station shows that the 3D scanning deformation monitoring is basically consistent with the data value and standard deviation measured by the total station, the data fluctuation is small, and the monitoring results are stable. It is suitable for the whole-process deformation monitoring of large space steel structure projects.

Abstract:
Parametric design is a method of three-dimensional forward design based on the internal connections and constraints of bridge structure design. This method can effectively improve the efficiency of structural adjustment and optimization. In the plan and preliminary design stage, the parametric design concept can be used to optimize the rationality, economy and aesthetics of the bridge structure to meet the social needs of the diversified development of the bridge at present time; in the construction design stage, by adjusting the independent variable parameters, It can flexibly adjust the detailed structure of the bridge and automatically interact with the two-dimensional design drawings, which greatly improves the design efficiency and quality. Based on the "R+GH" parametric platform, this paper proposes a parametric design process for bridge structures, and further verifies the practicability and efficiency of the design idea through the application of engineering cases.

Abstract:
In recent years, with the rapid improvement of material and spiritual living standards, people′s demand for high-quality cultural and entertainment activities has increased. China is gradually becoming the world′s premier theme park market. Because large theme parks often have distinctive features that are different from ordinary cultural tourism towns, such as their large number of complex structures, a large number of cutting-edge dynamic recreational equipment, etc., they have brought great construction difficulties to the construction of theme parks. This article will take a theme park in Beijing as an example to detailly introduce the application and the practice of forward design of complex structures in theme parks by using BIM technology as a digital design method.

Abstract:
With the development of society, Building Information Modeling(BIM)technology is getting more and more attentions in all aspects of society. However, the BIM is not accurate constructed by the current methods, which can hardly be used in practice. The accurate BIM construction method has been proposed in this paper based on the fusion of multi-source data. The three-dimensional(3D)laser point cloud data(3D LPCD)can fuse geometric feature information of 3D LPCD with measurement data, building drawings and material picture information, to construct the fine BIM and enhance the application of fusion fine BIM in internal repairing projects.
