The construction industry is facing a new opportunity to be reborn as a high-tech industry through the spread of smart construction technology as it converges with the advanced technologies of the 4th industrial revolution such as IoT, robots, and AI. In particular, BIM, a convergence technology of three-dimensional design and big data which integrates and utilizes information from the entire construction cycle. BIM effects planning, design, procurement, construction, maintenance, and enables stakeholders at each stage to efficiently manage their information. It can be said to be a key means of smart construction that can maximize the productivity, constructability, and efficiency of the construction process through better communication and collaboration. The Ministry of Land, Infrastructure and Transport (MLIT) will actively support the early settlement and activation of BIM in order to completely reorganize the existing construction process based on two-dimensional drawings and a segmented execution system for each construction stage. To this end, MLIT intend to realize smart construction through innovation, through the full introduction of BIM and an integrated collaboration system. MLIT would like to establish a guideline system that suggests procedures and methods. The BIM guideline system is divided into the basic and implementation guidelines commonly presented by the Ministry of Land, Infrastructure and Transport and the application guidelines set according to the characteristics of each client.
The first publication from MLIT is the Construction Industry BIM Basic Guidelines, which is the highest common guideline dealing with basic principles and standards for the application of BIM in the construction industry, and the Construction Industrial BIM Implementation Guidelines. In addition, the client groups should prepare the BIM application guidelines for each sector and the BIM practice guidelines for each sector that determine detailed implementation plans according to the type of project and the practical characteristics of each client. As the first step, the Ministry of Land, Infrastructure and Transport has published this Basic Guidelines for Construction Industry BIM which is the highest level guideline, and plans to prepare the Construction Industry BIM Implementation Guidelines in 2021. In addition, MLIT plan to release the Construction Industry BIM Roadmap, which includes BIM development strategies and action plans, such as the mandatory application of BIM for public construction projects. It is hoped that this Basic Guidelines for BIM in the Construction Industry will serve as a good opportunity to smoothly discuss BIM application standards and required levels among implementing entities, and to actively share and utilize various construction data to enhance synergy.
BIM is a high-potential future innovative technology with high potential for exchanging and utilizing building information. The World Economic Forum (’16) selected BIM as a ripple technology for the building and construction industry. BIM-based design is effective in improving design office work efficiency and productivity by improving design quality by minimizing construction errors. This BIM roadmap document looks at how BIM should be implemented, the challenges and how these can be addressed.
The main part of this document looks at the diagnosis of problems, these include:
1. The need to improve standards, systems and administrative systems for BIM utilization. There is currently an inadequate practical application of guidelines because the standards for creating BIM models for each design and construction stage and submitting BIM models/books are not specific
2. The lack of infrastructure for BIM utilization and insufficient technological development. International standards ISO 16739 and ISO 19650 were enacted, but in the case of a domestic BIM national standard and data management environment there is insufficient basis for BIM utilization.
3. There is insufficient training for BIM. Projects are currently outsourced to BIM-specialized companies due to lack of BIM performance of design practitioners due to scattered educational programs and BIM certification operation.
4. There is insufficient BIM integrated management due to lack of an official BIM operating organization. Establishment of a BIM implementation strategy for BIM-related policies, R&D and revitalization is needed.
The Ministry of Land, Infrastructure and Transport (MOLIT) plans to enter the ranks of smart construction technology leaders by securing a core technology package that can be immediately distributed across construction sites by 2025, improving productivity in the construction industry by more than 25% and reducing construction periods and disaster rates by more than 25%. Productivity in Korea is currently low compared to other regions (DOLLAR/HOUR): Korea 18.7, Spain 42.9, UK 30.4, France 37.1, Germany 32.1. The MOLIT will launch a “smart construction technology development project” with approximately 200 billion invested by 2025, and research institutions will be invited to support this initiative.
The “Smart Construction Technology Development Project” consists of four major areas (12 detailed tasks) and is comprised of approximately KRW 200 billion for six years from this year, As a large R&d project it can dramatically transform the entire construction process, including real-time integrated control for earthwork equipment automation and collaborative construction between multiple equipment, BIM-based modular construction, unmanned remote construction using robots, smart safety management, and digital twin (twin models that reproduce real-world structures).
