n the year-on-year increase
in usage of BIM, 40% responded that the number is below
10% and those who responded as below 10%~50% were
reported as 40% (refer to Fig. 3). The response to answering
the question about the important changes of BIM varied.
40% responded that the changes were increased, 56%
answered that it is average, and only 4% answered that it
became lower (refer to Fig. 4).

compared to earlier year
Figure 4. Importance in Changes
of BIM
According to the survey result, the usage of BIM in civil
engineering field is continuously growing and the level of
awareness in users has been increasing as well.
3.3 Tasks that are to be applicable on BIM
For the question that inquired about which method BIM
would be applied if it was introduced, the highest was 15%
in which they stated that they want to utilize it for
The next highest was 10% with interference check,
quantity, process management, design and production of
drawing. Also, those included in the 8% were structural
analysis, maintenance management of facilities, automatic
quotation, and feasibility study. However, visualization,
analysis, and regulation check were relatively low (refer to
Fig. 5) .
By following the application of BIM according to the
research results, as the 2D delivery system switched into the
3D delivery system, it has been analyzed that it will create
effects in stimulation and interference check. Thus, even
though BIM can be utilized as a very strong tool for this law
card, there have not been sufficient amount of education or
applied cases regarding the content, resulting in a relatively
low outcome in the task where application is desired.
The rest of the opinions such as landscape management,
asset management, facility obsolescence forecast have been
reported as possible for application

3.4 Prediction of revenue in contrast of investment
through the application of BIM
In order to make predictions about the revenues, 8 items
were derived and were distinguished into 3 stages with
increasing state, no changes, and decreasing state. According
to the survey results in making prediction regarding the
revenue, the highest number was 92% stating that

multilateral communication and comprehension will become
increased. In addition, opinions which stated that optimistic
influence in marketing will increases took up 84%, those
stating that on-site safety will increase took up 80%, and
52% stated that task abilities in progressing projects will
become enhanced. On the other hand, there were negative
answers stating that productivity of employees will decrease,
project costs will increase, and project circulation time will
increase were high in numbers (refer to Fig. 6).
According to the survey result, due to the 3D
visualization, more distinct modeling has been made possible
as when compared to 2D formation. This led to amplification
in communication and comprehension, optimistic aspects of
marketing, and making it possible for prediction of site
safety leading to high revenue following pre-recognized
dangerous elements.
However, in relative terms, following the complexity of
modeling comes with the reduction in productivity of
employees as well as purchase expenses of BIM related
software, increased amount of time in production following
the complexity of the model, and acquisition costs of
professionals have been analyzed to cause negative influence
on the revenue structure. These are assignments that need to
be solved in introducing BIM to the civil engineering field.

application of BIM
Analysis of Importance that needed for application of BIM
In order to analyze the importance, 14 kinds of survey
items were derived and were divided into 3 stages such as
increase in the importance, no significance, and decrease in
the importance.
In the level of analysis results regarding the importance
in the application of BIM, importance of enhancement in
BIM software and compatibility between BIM software
applications took up the highest responds of 92%. Next were
opinions that stated the importance of educational training
regarding BIM application as well as detailed information
through 3D resulting product and possibility of production
took up 80%. The next highest responses were regarding
modeling service that can easily be used outdoors and
interests regarding BIM as well as owners and executive
officers. On the other hand, the opinions pointing out the
importance of cost reduction of BIM software was relatively
low. Therefore, the level of importance regarding software
cost was analyzed as the lowest (refer to Fig.7).

4. Conclusion
Based on the survey result on engineering companies,
application of BIM in the civil engineering field is
continuously increases, and the awareness of importance was
very high. Especially, it has been reported that introduction
of BIM in stimulation, interference check, calculation of
quantity, process management and drawing production
would cause a large effect. When BIM is introduced, the
areas that would display the biggest effects in contrast of the
investment are multilateral communication and increase in
comprehension, increase in positive impact of marketing,
and increase of site safety. On the other hand, it has been
reported that there are concerns regarding reduction in
productivity of employees, increase project costs, and
increase in the project time. The importance of application in
BIM have been reported as the functional enhancement of
relevant software and interoperability between software.
In order to do so, software manufacturing companies
related to BIM have to strengthen the cooperation system
and in addition to the national plans and policies needed for
settlement practices, development of related standards,
training program and education of BIM practitioners have
been considered as urgent. In addition, in order to
materialize the BIM product and clarify the scope of work,
related guidelines would be considered as important. This
research can be applied for future BIM ordering guideline
and evidence of related standard developed as well as basic
