“…e 7D BIM is composed of a 3D BIM, a 1D schedule management model, and a 3D project management model (bidding management model, enterprise quota management model, and process management model). As discussed in the Literature Review, academics and practitioners have come to a consensus that the 3D BIMs were visualized, 4D related to time, and 5D extended to cost [21,22,30], while the 6D and the 7D BIMs lacked agreement [34][35][36]. e 4D BIM developed in this study, which contains the 3D BIM and a 1D schedule management model, was consistent with previous studies.…”

With the fast expansion of major cities in China, increasing scale, complex, and tall buildings have been built to meet the increasing commercial and living demand. However, the efficiency of project management and investment is not always satisfactory. To solve this problem, a seven-dimensional building information model (7D BIM) is developed. To do this, a 3D BIM is firstly developed, which consists of architecture model, equipment model, steel framework model, other solid models, etc. Then, a 1D schedule management model and a 3D project management model (bidding management, enterprise quota management, and process management) have been integrated into the 3D BIM, thus forming a 7D BIM for a complex project. By providing a clear 3D vision in modeling the construction process, the proposed 7D model can be applied to help engineers/project managers carry out clash detection, structure design, modification, equipment installation, 3D project management, and maintenance after construction. The performance of this model has been demonstrated through a case study of a complex project launched in China. The study shows that the implementation of the 7D BIM has achieved significant cost and time saving as well as project quality and work efficiency improvement.

“…However, beyond the fifth dimension, there appears to be a lack of agreement in BIMs. Sustainability, facility management, safety, health, energy, project life cycle, procurement, knowledge, and as-built operation were popular dimensions of 6D and 7D BIMs [21,22,30,[32][33][34][35][36][37].…”

Organizational Factors That Drive to BIM Effectiveness: Technological Learning, Collaborative Culture, and Senior Management Support

Senior management support is a key dynamic capacity for design companies in the architecture, engineering, and construction (AEC) industry, given the fact that they must identify changes in the competitive environment, which are increasingly becoming more and more technological. In addition, senior management support is obliged to react in the most efficient and effective way. Currently, the project design teams that have adopted building information modeling (BIM) are subject to constant changes in the technological environment, of which the activity is influenced by the behavior of senior management support. This research focuses on this issue by analyzing the role played by the variables of technological learning, collaborative culture, and support provided by senior management as precedents of BIM technology effectiveness. The data set has been obtained from 92 AEC companies in Spain. Using partial least squares (PLS), this research finds evidence of the previously mentioned relationships and the existence of partial mediation effects generated by technological learning and collaborative culture within the support of senior management in BIM technology effectiveness. In addition, this model achieves an appropriate level of predictive validation to explain BIM technology effectiveness in engineering project designs. The results highlight that senior management support needs to promote a technological learning and collaborative culture to improve the technological capabilities. The contribution and original value of the paper is to provide empirical evidence that the effectiveness of BIM factors in project design teams is influenced by the behavior of top management support.

“…To share and merge these data, it is necessary to explore the industry foundation classes (IFC) model of the BIM and the CityGML model of the GIS, and develop a method capable of automatically extracting the GIS surface model with multiple levels of details (LODs) from the BIM entity model. In this way, the LOD 100-400 models could be obtained from the IFC and CityGML model, overcoming the difficulty in merging the BIM with the GIS and paving the way for the CGB technology integration [2][3][4][5][6][7][8][9][10][11][12][13][14].…”

In urban rail transit projects, the traditional method of foundation evaluation faces problems like vague description, unclear process, and fuzzy evaluation system. To solve these problems, this paper sets up a scientific evaluation system based on CGB technology integration and analytic hierarchy process (AHP). The CGB technology integration refers to the integrated application of computer-aided design (CAD), geographic information system (GIS), and building information modeling (BIM). Taking Qingxihe Station, Line 6 of Chongqing Rail Transit (CRT) as the object, the authors constructed a 3D geological model of the construction site, created a novel three-layer system through data analysis, and evaluated and compared the suitability of each layer as the supporting layer of the foundation. Finally, effective suggestions were put forward on the selection of the supporting layer. Our research successfully visualizes the whole process of foundation evaluation, and enhances the accuracy of the evaluation results. The research findings provide a good reference for the selection of the supporting layer of foundations in urban rail transit projects.
