1 2016 International Conference on Manufacturing Construction and Energy Engineering (MCEE) ISBN: The Promotion Channel Investigation of BIM Technology Application Yong Li, Jia-Chuan Qin, Ming Liu and Yuan-Ming Liu ABSTRACT The Promotion of BIM technology application is an important process of the development of construction informatization in our country, which requires project owners, design units, construction units, government, etc. departments to work together based on BIM. In this paper, the promotion channel of BIM technology application is investigated based on AHP by analyzing the that influence the promotion of BIM technology application in our Construction industry. Keywords: BIM technology application; Influence factor; AHP 1. Introduction The Department of Housing and Urban released Construction Industry Informatization Development Program in May 2011, which clearly pointed out that the application of building information modeling (BIM) technology should be sped up, and special attention should be paid to the promotion of BIM, collaborative design, virtual reality, 4D project management, etc., technology in design, construction, and project management. Which will improve the traditional production and management mode and enhance production efficiency and management level. The government management departments, scientific research institutions, and other large enterprises carried out a series studies in many aspects since 2004, such as the standards of construction informationization, the application software of construction engineering based on BIM technology, the design and construction process of construction engineering informationization, and the key technologies and application of construction enterprise management informationization, etc., which generates great role in promoting the application of BIM technology in China's construction industry. However, the application of BIM technology is not a simple process of tool conversion, but the process of synergistic work between various departments including the project owner, design unit, construction unit, supervision unit, etc. In this process, there is a big difference in terms of the application goals of BIM, application mode, application personnel, equipment of hardware and software, and so on, between various departments involved in the project, which leads to the application and promotion of BIM technology far less rapid and universal than CAD. Therefore, it is necessary to analyze various types of that affecting the promotion of BIM technology application, to seek a reasonable channel of accelerating the promotion process of BIM technology application.

Analysis of the of influencing the BIM technology application Perfect application of BIM technology should be throughout the whole life cycle stages, including project planning, design, construction and operation, and each project participants rely on BIM technology to complete their work. Therefore, the process of BIM applications promotion may be affected by technology, organization, personnel, economic, legal. This study finds the five kinds of affecting promotion of BIM application by analysing BIM Application Research Report Of Chinese Engineering Construction in Explore ways to promote the application of BIM technology This study using Analytic Hierarchy Process (AHP) to investigate a reasonable way to promote BIM technology. AHP is a method that we can transform qualitative problem to quantitative problem, the principle is simple. Firstly, we divide the complex issues into the hierarchy in good order, then calculating the weights of the elements in each level. That is to say, making the use of matrix to make an objective determine in determining the importance of the scheme. Generally speaking, the problem is divided into the target layer A, guidelines layer B, C and program layer D.This study makes a survey, and make it clear the degree of influence of each factor and sorting by using AHP to build a hierarchical factor model. The research provides some referenced suggestion in seeking ways to promote the application of BIM technology. 3.1 Building the hierarchical model of the structure We must understand the problem before setting up evaluation model, especially ascertain the affiliation between the various. This research establishes a hierarchical model, which is shown in Figure 1.

We can clearly find that this matrix is symmetric matrix according to judgment matrix A-B, which is shown in table 2. So we establish the matrix, as long as we find out upper triangular matrix (above diagonal), such as B 1 :B 2 = 3, B 1, B 3 = 6, B 1 : B 4 = 1/2, B 1 : B 5 = 7, B 1, B 6 = 4, B 2 : B 1 = 3 and so on. We can set up judgment matrix B k - C km, C km - D (k = 1, 2, 3, 4, m = 1, 2, 3, 4) in the same way, its upper matrix on the triangle values is shown in table 3. a ij n 3.3 Single hierarchical ordering and check their consistency After constructing judgment matrix A, we should calculated the maximum eigenvalue λ max of judgment matrix A, Then to solve the eigenvectors W accord to the corresponding characteristic equation AW=λ max W,and normalized sorting out W at last; that is to say, we should calculate weight of the various on the same level relative to its upper, this process is called single hierarchical ordering. Because of the complexity of the objective things, when we construct the judgment matrix and contrast two, we often make mistakes, which will affect the credibility of single weight coefficient. Therefore, we must check their consistency after constructing judgment matrix A. The test formula is C.I.=λ max -n/n-1. CI: the indicators t of consistency; λ max : maximum eigenvalue of judgment matrix; n: the order of number judgment matrix. Calculating the proportion of consistency C.R.=C.I./RI, RI is shown in table

4 When C.R. < 0.1, the judgment matrix satisfies the requirement of consistency; when C.R. 0.1, the judgment matrix should be properly modified or abandoned. The criteria layer B and C also need to check their consistency in the same way, we check B k -C km C km -D matrix by 7.5 yaahp software, The test results are shown in tables 5 and Total ordering and check their consistency The process that calculating weight that a judgment matrix relative to the target layer (the top) is total ordering, which is composite step by step from the top to down. It assume that we has been worked out the j element of the k-1 layer: C.I. j (k) R.I. j (k). C.R. j (k), j=1,2,,m, so C.I. j (k) =(C.I. 1 (k),c.i. 2 (k) C.I. m (k) )w (k-1),r.i. j (k) =(R.I. 1 (k), R.I. 2 (k) R.I. m (k) )w (k-1). The test formula is C.R (k) =C.I (k) R/.I (k) When C.R. (k) < 0.1, the integral consistency of judgment matrix is reasonable, on the contrary, the judgment matrix should be corrected. We calculate weight sorting of D layer, the results are shown in table7, the consistency of D level: C.R. = < 0.1. It can be seen that the consistency of the model matrix can be accepted, so the model is reasonable. Table 4. R.I. The matrix order R.I judgmen t matrix Table 5.

5 4. Analysis of results The construction company is most appropriate to promote the application of BIM technology in the owner, design unit,supervision unit. According to the table 6, you can find that the weight of construction unit promoting BIM technology is , which is the top of the ranking list. The construction unit has obvious advantage to affect the application of BIM technology promotion, thus, we can make decision that the construction unit promote the application of BIM technology is most appropriate in the all project participants. The design and construction promoting BIM technology in combination is the best way. According to the table 6, you can find that the weight of the design and construction promoting the application of BIM technology is 0.75, the design and construction is the main influence power to promote the application of BIM technology. So the design and construction unit promoting BIM technology in combination is the best way. References [1] Yang Guo, Qie En-tian & Li Yong. Evaluation of Rural Residential Comfort Based on AHP.
