Research On BIM Technology Diffusion Trend In The Construction Enterprises

BIM is a technology that related to the construction project by digital express in the computer, popularization of BIM technology in the construction industry in our country is inevitable, but the application of this technology in our country is not wide enough. Prediction of BIM technology in our country construction enterprise spread trend, first of all, can get the fastest diffusion time, when it is for the construction enterprises in the enterprise adopt BIM technology provides reference basis. Second, know the trend of the spread of the BIM technology in the future, for the government in the process of the application of BIM technology to provide scientific decision basis, standardize the management, as well as how to make BIM technology standard, when formulates plans for the development of BIM technology, etc.When use the Bass model was applied to predict the spread of new technology trends and the lack of sufficient data, parameter estimation methods are analogy method and judging method. This article embarks from the spread of BIM technology in construction enterprise, through the first 19 kinds of information technology and innovation diffusion analogy, estimate the BIM technology diffusion coefficient of p in the process of innovation and imitation coefficient q, at the same time, by using the method of expert judgment on the market, most potential M and BIM technology diffusion in construction enterprises in our country the fastest date for judgment, then to estimate the parameter p1, q1. Obtained under the two methods M, p, q in the Bass model, using mathematical software MATLAB, we can get a BIM technology diffusion trend diagram of construction enterprises in our country, the result shows that from 2012 to 2022, this decade will be the golden development of BIM technology in the construction enterprises in our country. Respectively change the value of p, q, we found that increasing the imitation coefficient q values can significantly accelerate the diffusion velocity of BIM technology. Therefore, in order to accelerate the spread of BIM technology in our country construction enterprise, it is necessary to increase the imitation coefficient q value is, the need to technology diffusion to the combined efforts of the subject and technology adopters.
