Analysis of the User Recognition Changes

BIM, which recently emerged as a hot issue in the construction industry, is being recognized as a new breakthrough for the industry. However it is now in crisis due to the stagnant construction business and the decrease in the amount of orders. Already, various studies are being conducted to introduce BIM to architecture both domestically and abroad, but in civil engineering projects, unlike in construction pro-jects, the work system is non-repetitive, horizontal, and atypical, and the scope of the project tasks is so wide that the amount of information generated is vast. As a result, construction companies and designers feel burdened by the initial investment cost for BIM construction and have doubts about its cost-effec-tiveness. As such, to implement BIM in domestic civil engineering projects, this study determined the BIM technology level of designers in civil engineering and analyzed the changes in their awareness of BIM from the past so as to determine the obstacles to BIM activation in civil engineering and to propose a solution for such. The results of this study are expected to be used as the basic data for setting the direc-tion of the research on the standard for introducing BIM to civil engineering and on the development of a receipt inspection and verification system for supplied products.

Introduction

plan.

BIM (Building Information Modeling) is emerging as a new paradigm for improving the productivity of construction pro-jects. BIM can be defined as “a technique for producing and controlling all information applied to various areas during the life cycle of structures, from their planning and designing to their maintenance and control”. As opposed to construction projects, where BIM is actively being implemented, civil engi-neering projects have a non-repetitive, horizontal, and atypical work system, and their project scope is too wide that the amount of information generated is vast, causing constructors and designers feel burdened by the initial investment cost for BIM construction and to have doubts about its cost -effective-ness (Leen Seok, K., Seol Gi, K., Hyeon Seong, K., & Hyoun Seok, M., 2011). These reasons, however, are still not enough to explain the delayed introduction of BIM to civil engineering projects, which would have a huge impact on the country’s economy. It is also difficult to determine what would be needed first to solve these problems.

This study thus aimed to analyze the changes in the BIM awareness of the civil engineering designers who are either using BIM at work or have a higher understanding of it, to de-termine the related problems and to propose solutions to these. In particular, the various factors preventing the introduction of BIM were extracted from the current time and social needs but not from an activation plan based on superficial surveys, or by analyzing the awareness changes from the past, where there was a lack of social awareness of BIM, as well as the current status of the initial introduction of BIM, and based on the ex-traction results, this study aimed to propose a BIM activation

Review of Factors That Impede BIM Activation

According to the results of the survey published in the US SmartMarket Report in 2008, the factors that impede the appli-cation of BIM are the lack of pertinent education and of BIM specialists, the initial BIM cost, the lack of determination to introduce BIM, and the insufficient compensation (McGraw Hill Construction, 2008). For the problems, Bae pointed out the absence of standards for storing information in the existing 3D models and the fixation of the 2D-drawing-centered supply system (Kyoung Jin, B. & Han Jong, J., 2010). Kyoung Jin also discussed as the factors hindering the compatibility of the BIM software: the absence of a domestic standard information model, the establishment of the BIM process and its technical limita-tions, the lack of standard/guidelines/references/actual cases, the lack of specialists on BIM tools, and the need for govern-mental support (Jung Wook, P., Sang Chul, K., Sang Soo, L., & Ha Young, S., 2009). Jong Cheol argued for the urgent devel-opment of guidelines, including those on education, license acquisition, data compatibility, and ownership, as well as for systemic establishment (Jong Cheol, S. & In Han, K., 2009). Na et al. also discussed the lack of BIM specialists, the initial cost of SW purchase and technical training, and the lack of standardization for the process categorization and cost catego-rization systems (Kyung Jae, N., Kyoung Hwan, J., Dong-Gun, L., & Hee Sung, C., 2008). Meanwhile, Ha Neul pointed out the lack of awareness of BIM, the stagnant domestic construc-tion market, the cooperative structure that is in conflict with the BIM method, and the lack of specialists as the hindering factors

(Ha Neul, P. & Young-Sam, H., 2010).

These factors, however, are expected when BIM is imple-mented in domestic construction projects, or from foreign BIM introduction cases focusing on a small number of construction companies, and do not evenly reflect various interest parties, such as companies that have not implemented BIM, that are about to implement it, and large and small companies. There-fore, to determine the importance level of BIM activation, an additional survey is necessary.

Analysis of the BIM Awareness Changes

in Civil Engineering

Introduction

An analysis of awareness changes is required to determine the identical items or similar targets in time difference. There-fore, this study extracted the identical survey items based on those used by Korea Institute of Construction Technology in 2010 in relation to the BIM awareness of engineering compa-nies, which consisted of nine items in three groups: three items for BIM application, three items for the area of BIM application and the hindering elements, and three items for the demand diffusion effect when BIM is used (Table 1). For the survey, two interviews were conducted in June and July 2012 with 25 people from the 25 top subcontractors in South Korea. Through a comparison of the results of the survey conducted in this study to those of the 2010 survey, the BIM application level in 2010, the matters that need to be considered, and the demand diffusion effect were determined. For easier comparison, the 5-point criteria were converted into a 100% average.

Changes in the Awareness of the BIM Application Level

The converted average of the changes in the awareness of the BIM usage increase rate by year was 56.1 in 2010, and this decreased to 52.8 in 2012. Also, the change in the awareness of the importance of BIM by year was 82.8 in 2010, which also decreased to 78.7 in 2012 (

Figure 1). Particularly noteworthy in the survey results on the changes in the awareness of the BIM-applied tasks is the fact that the

awareness of the effectiveness of BIM on facilities maintenance

and control showed the largest change. This result is due to the decrease in the number of new civil engineering projects and the increase in the maintenance and control costs in recent years, and it is believed that such result reflected the expectation that the appropriate implementation of BIM makes it easy to deter-mine the life cycle of buildings and the exchange cycle of fa-cilities so that its application in the facilities maintenance and control stage will have a very large impact. Also, it was deter-mined that further research is required to help improve various types of decision-making processes, such as measuring the value of public facilities, predicting the rate of deterioration, and efficiently distributing the maintenance and control budget by increasing the visual effects through the combination of the facility information and the information on the existing topog-raphy based on GIS, etc. (Figure 2

).

Changes in the Awareness of the Matters to Be

Considered and of the Demand Diffusion Effect When Using BIM

The results of the survey on the changes in the awareness of the effects of the use of the BIM solution showed that while the awareness of the improvement of the project design quality, the enhancement of the construction and maintenance functions, and the improvement of communication among various parts of the design and other phases of construction increased, there was also a change in the awareness that the project performance

speed would increase and that the construction cost would rise drastically. The high displacement on the effect of the im-provement of communication among all the parts of the design and construction phases signifies that while BIM modeling was recognized in the past as something that would solve all prob-lems, the real function of BIM has now been realized. While BIM may mean cost increase for designers in the short term, in the long term, it will revive the construction industry by creat-ing a new construction market. As such, various efforts to cor-rect the interested parties’ negative preconceptions of the in-troduction of BIM are currently being exerted (Figure 3).

As for the survey on the awareness change in the areas re-quired for the establishment of BIM at work, the view that gov-ernment-led planning/policies and standards would be neces-sary was relatively higher than the others. Particularly note-worthy is the over 33% change in the need for business val-ue/efficiency review for the implementation of BIM at work, showing that many institutions want a soft landing rather than the implementation of drastic changes to the BIM system, after sufficient preliminary reviews. Furthermore, it is shown that public institutions should consider a new ordering system in-cluding BIM to expand the BIM market in civil engineering (Figure 4).

Proposed BIM Activation Plan in

Civil Engineering

Compared to 2010, the initial phase of BIM introduction, the BIM recognition level in civil engineering has increased overall, but the BIM usage increase rate or importance level awareness has decreased. The key factors accounting for such a result may

include the lack of BIM-related demands, the absence of regu-lations or guidelines related to BIM, and the difficulty of in-vesting as it is difficult to recognize the time needed for and cost of substituting 2D products with 3D products. To solve these problems, it was determined that the effects of BIM should be actively promoted by discovering various application cases according to the introduction of BIM, changing the deliv-ery/contract/business management processes based on the BIM ordering system, and analyzing the business value, and in tan-dem, the government should revise regulations and systems and develop related standards. In addition, further research is re-quired to develop plans to make construction projects com-petitive by combining the mobile, clouding, GIS, and other state-of-the-art IT technologies and by sharing, exchanging, and utilizing construction information.

An analysis of the awareness changes should focus more on the differences than on the similarities, which means that the BIM awareness of the companies that have experienced BIM implementation has changed in the process of the implementa-tion, and accordingly, various activation plans could be pro-posed to proactively cope with such a change.

Whereas in the past the key BIM tasks were either simulation or interference check, nowadays the users are recognizing the demand for the use of BIM in facilities maintenance and control as well as the importance of the cooperation between the de-signer and the contractor, which is the basis for determining that the users’ overall understanding of BIM has improved. The fact, however, that according to pertinent reports or reviews, the business value and efficiency of the BIM implementation at work has increased by over 35% shows that to satisfy the

higher expectation of the users and to activate BIM, it is im-portant not only for the government to actively promote BIM but, more importantly, to assure the users that their profits will increase when they use BIM, and to promote the designers’ and contractors’ proactive participation as well as not to effect a drastic change in the BIM system but to effect the system’s soft landing.

Conclusion

This article proposed various BIM activation plans by ana-lyzing the changes in BIM awareness. The proposed plans are significant in that they show the future direction of the BIM-related research that is to be actively conducted in civil engi-neering. It was also determined that the results of this study can be used by companies that plan to introduce BIM as these can

help them determine in advance the various factors that may hinder BIM introduction, and minimize the errors in such en-deavor. Furthermore, the proposed activation plans should be realized in the mid- to long term, not allowing short-term out-comes but a natural change towards the BIM ordering system based on the cooperation among the industry, academe, re-search, and government sectors.
