Abstract:
A number of studies have shown that individual differences will lead to differences in cognitive styles. In order to improve the personal risk perception ability of construction workers, therefore it can ensure the personal safety of workers, prevent on-site accidents and realize the safety management for various people. Based on the personality traits of construction workers, this paper studies the variance of risk perception ability of construction workers with different traits by eye movement experiments. The risk perception of construction workers in different scenes is statistically analyzed by these following six terms: the number of fixation points in the AOI interest area, the first fixation time, the average fixation time, the total fixation time, the eye gaze trajectory and the gaze hot-spot map. These results obtained in the paper are as follows: workers with obvious neuroticism and extroversion are comparatively weak in attention and stability of risk perception. Workers with obvious agreeableness tend to perceive risks in an unsafe state, while workers with obvious openness incline to perceive risks by notifying stimulating things. Workers with obvious rigor are most cautious and in-depth in judging risks, and also have strong and stable risk perception ability. This study provides a reference for the screening and management of constrcution workers, and further helps reduce accidents in construction sites.

Abstract:
In order to improve the safety supervision of workers on the construction site, yolov5 target recognition algorithm combined with UAV tilt photography three-dimensional modeling technology are applied to create the intelligent detection model of unsafe state on the construction site to identify and position human, machinery and other targets. Through experimental comparison and analysis, the paper determines the optimal target recognition algorithm and constructs the multi-target recognition model. The results are in line with the theoretical conjecture, and the overall average recognition accuracy reaches 91.6%. After recognizing the target, its relative position is further determined with the spatial position information provided by the tilt photography three-dimensional model, which manages to ensure the safety state of workers. The accuracy of this visual positioning is determined by the three-dimensional model. It is verified that the distance error of the three-dimensional model constructed by UAV tilt photography is about 1.5% and the range length is greater than 35m, hence the distance error will be less than 1%, which notes the high accuracy for the distance of the object recognized by the target recognition model.

Abstract:
The common method discrete placement of "families" along road and bridge in the process of BIM modeling always leads to the low automation level, high production cost, less positioning accuracy and large positioning deviation of family members. This paper proposes a new BIM intelligent modeling method on the basis of the Dynamo visual programming platform for accurate positioning and placement of family members driven by data. In order to realize the precise positioning and placement of the nested family of the adaptive conventional model, the paper carries out the parameter data processing and local coordinate system modification by functioning the rotating placement program of the adaptive nested family. Taking the construction and placement of adaptive nested family of street lamps and guardrail in a bridge project as an example, its results prove that the automatic placement modeling method established in this paper can effectively avoid manual placement errors and improve placement accuracy compared with the manual modeling method. The average running time of the program under the automatic placement modeling method is reduced by about 60% in contrast with the traditional parity column classification modeling process, which can promote the wide application of accurate placement of family in the process of BIM automatic modeling, and accelerate the BIM construction in linear engineering fields, e.g., road and bridge.

Abstract:
The parametric modeling based on the domestic software BIMBase can handle the models with peculiar shapes and complex curves, complicated modeling process and model modification by using conventional three-dimensional modeling methods. Taking the pedestrian arch bridge as an example, this paper introduces the BIMBase parametric modeling process, studies the parametric modeling method for the bridge, and then sets the relevant parameters of the bridge based on python language writing code, after which the corresponding correlation of the model geometry information is established to realize the parametric modeling of the pedestrian arch bridge. Hence it succeeds in checking the accuracy of the model and comparing the conventional three-dimensional modeling method with the BimBase-based parametric modeling method. This parametric modeling method effectively manages difficult modeling, cumbersome modeling process and model modification of the pedestrian arch bridges. What's more, this method also improves design efficiency and realizes large-scale rapid model design, which shows that BIMBase parametric modeling is feasible and advanced in three-dimensional modeling, and provides a reference for BIMBase-based parametric modeling technology.

Abstract:
Digital Twin can establish an accurate correspondence between actual objects and digital models, so that digital analysis can be performed based on data to guide the improvement of the objects. Taking the civil engineering building at University of Science and Technology Beijing as an example, the fire safety assessment of the building and retrofit was implemented on the basis of digital twin framework. Firstly, Building Information Modeling (BIM), Internet of Things (IoT), and Cloud technology are employed to collect and integrate the real-time sensing data (e.g., wind speed and number of people) and thus establish a digital twin model of the civil building. Secondly, the simulations on fire and evacuation by using sensing data are performed under the digital twin model, and results processed by traditional estimated data are compared. Finally, the paper proposes the retrofit plans of building fire safety and retrofit effects are tested according to the results above, which provides accurate references for building fire safety retrofit. Moreover, the results in the paper note that the results of the fire safety assessment by using the digital twin framework are closer to reality, hence it can guide building fire safety retrofit.

Abstract:
The application of traditional Gustav Purt fire assessment in urban village does not integrate the necessary information quickly and fails to represent the scope of visualization, and Geographic Information Systems (GIS) is also not well suited for complex buildings, e.g., urban village. To remedy these deficiencies above, this paper analyzes the feasibility of GIS+BIM technology for fire risk early warning management in urban village and verifies it by case studies from the perspective of risk early warning management method. The case study finds two pressure relief of the building complex, which played a positive role in the fire risk early warning management in the urban village. Compared with the traditional method, GIS+BIM technology is more scientific and reliable, which achieves cost reduction when applied to the Gustav Purt fire assessment in urban villages.

Abstract:
The expansion of the coverage area of underground rail transit leads resulting that the construction of underground structures in many construction projects is closer to the scope of subway tunnel, which further brings about that the adjacent construction will disturb the soil around the subway tunnel and cause deformation and displacement of the tunnel structure, therefore affect the service performance. Taking the Wuhan Three Town Center Project as an example, this paper describes the automatic continuous monitoring scheme for the service behavior of subway tunnel structure for three adjacent subway constructions including TRD construction, diaphragm wall construction and MJS soil reinforcement. What's more, the paper analyzes four automatic continuous monitoring items, i.e., crown settlement, ballast bed settlement, horizontal displacement and radial convergence and finally summarizes the impact of adjacent construction on the service behavior of subway tunnel structure, which can provide a reference for the following relevant projects.

Abstract:
The rebar size is manually input into the numerical control processing equipment of the rebar by steel bar processing workers, which might lead to the error information input and seriously lowered processing efficiency of rebar. In response to it, a method of extracting steel processing data from the IFC file and digitally transmitting it to CNC rebar machining equipment was proposed in this paper, through which, rebar entity formation is parsed and extracted from the IFC file and then encoded in BVBS format. On this basis, the coded data converted into PDF417 barcode format is submitted to rebar processing workers. Rebar processing workers in the processing factory input rebar processing information into MEP rebar CNC machining equipment via scanning QR codes. This proposed method has been applied in the Hefei-Zongyang Section of the Dezhou-Shangrao National Expressway. The technology in the paper is proven to be effective in cutting the intermediate links such as workers' diagram reading and input and improving the processing efficiency and accuracy of rebar through converting the steel bar model in IFC format into CNC machining files.

Abstract:
With many bridges and long tunnels, the extremely harsh geographical and natural climatic conditions of the highway located in the western Gobi Desert area of China results in high technical difficulties, construction risks, and management requirements, therefore leads to great challenges to the traditional project construction management. Depending on the development dividend of "BIM+" technology in highway engineering, the paper develops an information integration service platform to employ BIM technology through multi-channel and multi-means hence to solve the problems of project construction management, e.g., difficult information sharing, weak resource coordination and incomplete integration of construction and management, and realize the information management of engineering projects. This paper focuses on the main application of BIM technology in the construction management of a highway project as well as its extended application. Through employing BIM technology to realize the informatization management and innovative application of this project, which provides a reference for the subsequent highway construction.
