Non-USA Professionals’ Perception of Key BIM Maturity Indicators

The values and barriers of BIM implementation combination evaluation based on stakeholder theory: a study in China

“…The KMO = 0.392 is less than 0.500, we know that the Bartlett test of sphericity is used to test whether the correlation matrix is a unit matrix, that is, to test whether each test variable is independent. From the factor analysis results, we found that χ 2 = 63.862, df = 36, p = 0.003, rejecting the null hypothesis, refer to the criteria for factor analysis of Chen and Lin (2018), indicating that factor analysis can be done. Due to the conflicting and contradictory results of KMO and Bartlett test of sphericity, we follow the practice of Chen and Lin (2018), instead of extracting common factors according to the principle that the eigenvalue is greater than 1, we use all test variables as the calculation of the values of the BIM implementation principal component eigenvector values for all associated.Process of factor analysis.…”

Based on the results obtained by the suitability assessment, we adjusted the starting eigenvalues obtained by factor analysis, using the nine factors of the barriers of BIM implementation, whose cumulative contribution rate reached 100% (as shown in Table 11).…”

“…We used the independent samples t -Test method to calculate the discriminant. Referring to Chen and Lin (2018)'s definition method of high and low grouping for the discrimination of sample items, the 27% samples in the front and rear are set as high and low groups respectively ( N = 104, that is, the number of samples in high and low groups is 28), use the compute variable in transform to get the total score of each variable, so as to establish high- and low-group sample groups. The independent-sample t -Test results are shown in Tables 3 and 4.…”

A Benefits Prioritization Analysis on Adopting BIM Systems Against Major Challenges in Megaproject Delivery

“…Although it is a persistent problem on the overruns of budget and schedule according to many reports and research into megaproject delivery, there are various causes of the overrun problem among individual megaprojects, and the correlation of overruns between budget and schedule is always evidential. According to the two case studies on the SCL project in Hong Kong, and the BER project in Germany, it is not identical regarding the adoption of BIM systems can work well to confront the overrun problem, as the SCL project has also encountered the problem of overruns (Chan, 2018) in relation to extreme engineering challenges such as the movement and uneven settlement of the ground in the process of carrying out this largescale underground works (The Legislative Council Commission [LCC], 2018). In comparison with the BER project in Germany, the five lessons summarized above are also relevant to the SCL project in Hong Kong with regard to the need for a set of comprehensive data and information to be features into BIM systems at an early stage of megaproject delivery.…”
