Rapid Estimation Model of Green Building Engineering Cost Based on BIM Technology

The introduction of the Building Information Model (BIM) has had a profound impact on the construction industry. The information technology-based construction model has also changed the other aspects of construction project engineering while creating collaborative work methods. At the same time, with the implementation of the theory of sustainable development, green building projects have increased significantly. However, there are many problems in the current cost of green building projects, such as many sources of data sources, non-uniform standards, and low level of refinement. In this context, this paper deeply analyzes the necessity of BIM technology applied to the cost of green building engineering, and proposes three rapid estimation models based on BIM technology, in order to provide some reference for the benefit of enterprise capital investment. 1. Research background 1.1 Literature review With the rapid development of the national economy, green building is the key development direction of the future construction industry. Investment in the construction industry has shifted from a single to a diversified, and the realization and guarantee of various stakeholders has become a research hotspot. At the same time, BIM technology has entered a new phase in the development of the construction industry. In terms of the cost of green building projects, exploring the application of BIM has become a research hotspot. Lian Liling takes a comprehensive office building in Dalian as an example to establish a 3D-BIM information model and introduce it into the BIM subsystem. Compared with the traditional method, the new method is simple and intuitive, and has certain practical significance (Li, 2018). Zhang Lei, Jiang Li and others believe that green building is the only way in the process of sustainable development. Using computer technology, the BIM information model was established, and the design and evaluation of green building cost were integrated and managed, and the three-dimensional data information was used to realize the green building evaluation function (Zhang et al, 2018). Li Xuemei analyzed the construction projects of the market, explored the three challenges facing the cost of green building projects, proposed the BIM5D model, and selected the factors such as the process as the optimal factors to maximize the capital efficiency of the enterprise (Li, 2019). Wu Jiawei, Li Xisheng and others focused on the evaluation of green building sites. Based on the information classification of BIM models, a comprehensive design evaluation model was established. The DB Link plug-in and Excel spreadsheet were used to verify the feasibility of the model (Wu et al , 2017). Zhao Zhian, Qiu Xiangwu and others combined the evaluation criteria of green buildings to analyze existing problems and proposed that BIM technology can effectively solve massive data problems. On this basis, the concept of generalized building information model is proposed (Zhao et al, 2012). Wu Enzhou, Li Min and others raised the superiority of BIM in the cost of green building projects in response to the consumption of building energy. Studies have shown that the application of BIM technology can assist in the engineering cost process (Wu et al, 2017). 1.2 Purpose of research The project cost has always been an important part of the construction project and one of the 2019 4th International Symposium on Management, Economics, E-business and Marketing (ISMEEM 2019) Copyright © (2019) Francis Academic Press, UK DOI: 10.25236/ismeem.2019.019 100 main means to ensure the maximum profit of the investment. In order to ensure the core competitiveness of the construction, design and construction companies, it is necessary to continuously improve the project cost. Green building is an important development direction for future buildings, and its current application software is not cutting edge. The building process can not only be reflected, but also the phenomenon of capital investment, construction technology, project management and so on. Although BIM technology has been greatly developed in recent years, combing the existing literature can only focus on the main links of the whole life cycle of buildings and the evaluation of green buildings. Few scholars have studied the application of BIM technology in the cost of green building projects. . Therefore, it is of great practical significance to establish a rapid estimation model for green building engineering cost based on BIM technology. 2. Overview of relevant theory
