“Expectations for CIM (BIM for Infrastructure) in Innovation of Construction Production Systems”
On September 7, 2016, the International Roundtable Meeting entitled "Expectations for CIM (BIM for Infrastructure) in Innovation of Construction Production Systems" was held under the auspices of the Japan Society of Civil Engineers (JSCE) IAC as part of the International Program of the 2016 Annual Meeting. The names of the speakers and programs are shown in Table 2.
The International Roundtable Meeting started with opening remarks by Tamiharu Tashiro, JSCE President, followed by the keynote speech by Prof. Nobuyoshi Yabuki of Osaka University, serving as the meeting chairperson. CIM, which is generally used as the abbreviation for Construction Information Modeling/Management, represents a technology used in the field of civil engineering and construction. Through the use of this technology, engineers are able to construct a visual representation of a building on the computer and add various types of information related to cost, management, etc. The accumulated information is utilized during the entire process from planning of the building to its maintenance and operation. In the keynote speech, Prof. Yabuki explained that CIM is expected to help solve the problem of the shrinking workforce and aging of workers in the construction industry and also to help solve problems resulting from vertically dividing the information on a construction project; presently, the information is divided according to the process for which each company is responsible. Also, taking into consideration the history and future of CIM in Japan and the rest of the world, ISO standards (Industry Foundation Classes: IFC) for product models of buildings, which serve as the standards for CIM, were established in 2013. Professor Yabuki stated that CIM is expected to see further development in the future.
The keynote speech was followed by the presentations delivered by speakers from foreign civil engineering societies enjoying a collaborative relationship with JSCE. The speakers introduced the environment surrounding CIM technology in their regions and referred to actual examples of its application. For example, in Taiwan, the application of CIM has been promoted since 2010, and it is now proactively introduced by organizations in industry, government and academia. The speaker described the activities carried out by those organizations. It was also reported that the introduction of CIM in Hong Kong made it possible to quickly estimate costs visually at the planning stage, which helped to avoid, in advance, the risk of misalignment and interference of structural members as well as the interference of a structure with construction equipment that could occur during the execution of construction work.
In the discussion, the primary focus was on the education and dissemination of CIM technology. For example, CIM education is provided in only a limited number of universities in Japan. In Taiwan, which is one of the regions where CIM education is promoted, some universities provide an educational course on CIM technology, but such programs started only five years ago; plans are underway to develop those programs. However, the education examples such as those seen in Taiwan are not commonly found in other regions. Thus, it was shown that most regions are facing the challenge of how to promote CIM education. In addition, a question was raised about the difficulty of providing education on 3D CAD, which is a required technology for BIM/CIM. The question was as follows: It takes a long time to teach how to use 3D CAD, so wouldn’t it be difficult to provide 3D CAD education within a university, considering that it is a research and education institution? One of the responses to the question was that since 3D CAD will be an essential technology that almost all engineers have to learn, the education should be provided as part of basic technology. There was also an exchange of opinions over how CIM can be utilized to rationalize and improve the present condition in which the construction process is divided into several steps such as design, construction work, etc. As an example of the pursuit of rationalization, it was reported that Integrated Project Delivery (IPD), which is an approach that allows the owner, designers and constructors to collaborate from the initial stage and to share information and be involved in decision making, has already been introduced in some projects in America. In this approach, centralization and sharing of information is an indispensable element, and it is CIM technology that makes this possible.
The room for the roundtable meeting was packed with participants, who engaged in the discussion so enthusiastically that they felt they needed more time, which showed that CIM technology is attracting a high degree of interest.

2016 MACE Annual Meeting and International Program
During the 2016 Annual Meeting of Mongolian Association of Civil Engineers (MACE), International Joint Seminar on “Construction Project Management & Implementations: International Case Studies” and International Roundtable Meeting on “Building Information Modeling (BIM) towards to Social Development” were held on 9th and 10th June 2016 in Ulaanbaatar, Mongolia. Mongolia, South Korea, Taiwan, Philippines and Japan participated in these international meetings. JSCE delegation consisted of Prof. Eiki Yamaguchi, Kyushu Institute of Technology and Mr. Keita Nakasu of National Institute for Land and Infrastructure Management, the author of this essay. In the Joint Seminar on Construction Project Management & Implementations, I explained on the Japanese cooperative relationship among industry, academia and government in risk allocation and research & development for public works projects in severe natural and social conditions.
The majority of Mongolian participants were architectural engineers. It would be easy to imagine that there are not many opportunities constructing major structures such as bridges and tunnels due to in a flat grassland. It was discussed that challenges in Mongolia were the applications of construction technologies in the projects which would be carried out in long and severe winters and logistic conditions without any port facilities in the country. In addition, countermeasures against earthquake were an important issue.
MACE suggested to the Japanese delegation to introduce a shaking table in Mongolia with Japanese technical assistance after the joint seminar. Earthquakes do not occur in Mongolia as many as in Japan; however, seismic designs for infrastructures are an unavoidable issue due to the historical records of large-scale earthquakes. According to the Mongolian standards, high-rise buildings require shake table tests to assess their seismic performance. Currently, Mongolian engineers use shaking tables in China, the nearest facility to Mongolia.
Generally speaking, large-scale expressways or high speed railways are contemplated as the subjects of ODA infrastructure projects. However, in some countries, there are few opportunities to construct the bridges and tunnels which require Japanese expertise. In addition, large-scale infrastructures increase the risks of land acquisitions, utility relocations and geological conditions. On the other hand, it tends to be seen that it is easy to control risks of building or flyover projects implemented in limited spaces. In the building or flyover constructions using advanced seismic designs or accelerated construction methods with prefabricated members, contribution by Japanese experience is clear and visible. I hope the discussions on this should be continued by related organizations in order to promote technical innovations as for the development of Mongolian infrastructures based on the collaboration between Mongolia and Japan.
