# Facilitators and Barriers in Applying Building Information Modeling (BIM) for Construction Industry
## 4 Conclusions  
This study is designed to understand BIM utilization in design and construction process for AEC industry. In specific, questions are delivered to analyze relevant professionals'

As the analysis indicated, although BIM seems to be in its early stage for more active involvement, there are quite many professionals already using BIM for their work. Especially, during designing and construction stage, many experts try to use BIM for a multi-purpose working environment. However, there are still a large amount of gap between BIM use and relevant professional's level of expertise. Although 45% of the respondents have received a certain form of BIM education, more than 94% of the respondents have required there should be a formal education regarding BIM and the length of the education should be 1 to 6 months, which is significantly longer than the current education experiences. In addition, more than 76% of the answers have identified that there should be a certificate system for BIM experts and it needs to be more than just a modeling certificate. It should be also connected to project management and project implementation at large. More than 70% of the respondents have positive attitude toward knowledge sharing platform and the most demanding contents are specific guidelines and education materials for BIM. According to the survey result, both design and construction experts have reported that the biggest advantage of using BIM is in its error checking ability. It can reduce design errors and increase construction ability for participants. Both design and construction experts are in high demand for specific work guidelines and more detailed procurement and project delivery. They have also denoted that a lack of professionals for BIM modeler and coordinator in AEC industry is another obstacle. This perception was relatively similar for rail industry professionals. Specific questions regarding rail industry showed a similar result as they require more detailed work guidelines and more dedicated professionals for BIM delivery. From the government side, they expect data delivery and management as a big asset in BIM utilization. Additionally, more than 79% of the respondents agreed upon a proper compensation system for BIM implementation. Although compensation allocation differs to a certain degree between design and construction, the majority of opinions have revealed that there should be an increase in construction and design fees for a proper BIM adjustment. As many have noted, BIM can change AEC industry with many advantages. In specific, relevant professionals expect error reduction and data management as two biggest assets. Examining the survey result more specifically, regardless of age, professional backgrounds, affiliations, years of experience, and BIM education, most of the respondents have agreed that AEC industry should adopt BIM for a better productivity and efficient project management. There are, however, some differences among stakeholders, industries, and other perceptions and for that reason, BIM should be adjusted for its own industrial standards. Nonetheless, a vast amount of answers has accentuated that there are a number issues for a successful BIM application: (1) guidelines and details for BIM work and delivery; (2) more standardized BIM education; and (3) a proper compensation system for BIM work. These results show that BIM professionals are ready to adopt the consequences of using BIM, but administrative and political preparations are not available beforehand. Specific guidelines for project delivery, standardized education, and compensation all relate to systematic and organizational efforts. Many have noted the importance of using BIM in a very technical perspective.
