[2014] Convergence Technology for BIM/GIS-based Construction Space Information Project Leader : Choi Hyun-sang (Research Fellow, hyunsang@kict.re.kr) KICT has developed a new-concept software platform that converges Building Information Modeling (BIM) 3-dimensional design information utilized in civil engineering, construction fields and Geographic Information System (GIS), space information system 3-dimensional (GIS), while developing application technologies in construction fields based on the utilization of convergence technology and international standards for road facilities. This type of platform will enable the use of precise 3-dimensional design information (previously utilized only in the design process) in the maintenance and management stage to reinforce the function of combined control in fields as ‘Building Energy Management System (BEMS),’ ‘Intelligent Building Management System (IBS)’ and ‘Underground Precise 3-dimensional Lifeline (water and sewage / electricity and communications) Management System.’ It can also be utilized as a system to manage industrial complexes and plant facilities located in large areas or the operational management of university campuses and large-sized apartment complexes; in addition, it can be utilized as ‘a smart city management platform.’ Research Results This study utilized information of BIM and GIS on an SW platform. We applied development technology on-site and conducted commercialization through technology transfers. Achievements have included academic results such as the publication of international SCI papers, industrial patents and technology transfers. • Completion of 1 technology transfer case for a BIM/GIS mutual operation platform (GAIA 3D) • Completion of on-site applications utilizing the KICT building facility management system, Civil 3D, Map 3D and Storm Sewer Analysis; in addition, the analysis of the LID facility installation effect is to be applied virtually at a neighborhood park in Yangjae Korea. • Actual application of the construction business for the management system for sites (regions) and facilities at the Polar Research Center/King Sejong Station at the South Pole • Seven amendments for government technology standards: 5th Construction Technology Promotion Basic Plan (Long-term Plan of Ministry of Land, Infrastructure and Transport, 2013), Laws on the Promotion and Support of the Re-use of Water (Ministry of Environment, 2013), Rules on the Standard of the Decision, Structure and Installation of Urban and Provincial Plans (Ministry of Land, Infrastructure and Transport, 2013), Guidelines for the Investment Evaluation of Transport Facilities (Ministry of Environment, 2014), Legal Ordinance Enforcement Rule for the Promotion and Support of the Re-use of Water (Ministry of Environment, 2014) • 42 Korean registered research papers and 3 SCI / SCIE research papers • 10 Korean patents and 1 international patent (USA), 33 software programs registered, and 55 media reports Utilization and Impact Research achievements have enabled the utilization of building information (BIM) and spatial information (GIS) on one integrated platform. Results will help realize a ‘smart city’ previously only envisioned in movies or games (such as SIMCITY). Small and medium-sized companies participating in this study have expanded actual business fields through a technology verification process that has helped establish ‘a facility management system for the King Sejong Station located at the South Pole’ operated by the Polar Research Center based on the BIM/GIS platform. Further research will expand application opportunities into various areas for large-sized disaster response systems for large-sized building complexes, combined management of underground facilities and structures (believed to cause urban sinkholes), and an energy management system for skyscrapers and smart cities.

[2014 WBT] Safety-Secured NATM Tunnel Construction Technology [KICT 2014 World Best Technology] Project Leader : Kim Dong-gyou (Research fellow, dgkim2004@kict.re.kr) This technology enables the fast securing of tunnel structure stability and durable tunnel structures. The research objective was the development of high performance tunnel support at lower prices than current tunnel support that can activate opportunities in international markets and secure international technological competitiveness. The absence of safe domestic or international management technology for the construction of a standardized tunnel makes it imperative to develop a safe management system for tunnel construction engineering and provide technology leadership. The domestic standards for tunnel technology engineering and management technology are relatively weaker than general construction projects; therefore, the second objective is to develop technology that can predict tunnel construction hazards and secure a systematic construction management technology. Research Results This research develops advanced technology support for the safe construction required to blast and excavate tunnels as well as element technology to predict the degree of tunnel construction hazard; consequently, the commercialization process has been conducted through the site application of the development technology or technology transfer. Achievements such as revenue based on engineering fees from industrial patents and technology transfers are as follows. • Completion of the technology transfer for the high-performance shotcrete (fixed engineering fee USD 27 thousand, ordinary engineering fee 2%, SilkRoad TND Co., Ltd.) • Site application of high-performance shotcrete (application for 4 areas in the capital area high-speed railroad from Suseo to Pyeongtaek) • Completion of a technology transfer for a high-performance lattice girder support (fixed engineering fee USD 45 thousand, ordinary engineering fee 1%, Se-ahn Co., Ltd.) • Site application of the high-performance lattice girder support (application for Line 9 of the Seoul Subway - No. 918 area and No. 922 area) • Technology transfer and site application of the system for the management of the degree of tunnel construction hazard (fixed engineering fee USD 236 thousand, application for the Gwanak tunnel of the Gangnam Expressway) Utilization and Impact Technology development will enable advanced support to extend the lifespan of tunnels by 50% and help improve public living standards that could be affected by frequent maintenance, replacement costs and carbon dioxide emissions during the construction process. It is possible to obtain orders based on World Best Support Technology instead of obtaining orders based on simple construction technology in the global market. The new-concept safe construction management technology based on R&D will increase public recognition about the construction industry.
