PURPOSES : The Ministry of Land, Infrastructure and Transport (MOLIT) and its subordinate agencies have recently established various policies for the application of BIM and are implementing these policies, and are increasing project orders with the application of BIM. Developed countries where they have earlier adopted BIM provide BIM standards and guidelines at the national level to support BIM implementation by private-sector constructors. Domestic BIM standards and guidelines, however, have been lacking details on upper-level standards that have to be presented by ordering agencies, thereby limiting the practical application thereof. This study aims to provide BIM practice manual development measures to ensure the facilitation of the writing of BIM outputs and their delivery in the road sector. METHODS: This study first analyzed domestic BIM standards and guidelines, and examined BIM processes in the existing BIM guidelines to determine the major works required in each stage of the implementation of road construction projects. Further, the study determined those matters that were required in working BIM but were not specified in existing BIM guidelines. Those derived contents have been reflected in the definition of the configuration system in the table of contents of the BIM practice manual, and in the contents on the road sector, and the details of each configuration system have been specified. RESULTS : The proposed BIM practice manual for the road sector is a technical guide on BIM guidelines published by public ordering agencies, and provides the basic requirements and methods required for the writing of BIM models. Further, the manual provides working procedures and detailed methods for writing BIM to enable working-level staffers on BIM projects to construct BIM data. The proposed BIM practice manual was configured with considerations for domestic civil-sector BIM technology levels and will be further developed and improved according to the development of domestic BIM technology. CONCLUSIONS : In an effort to respond to the changing domestic construction technology environment, and to apply and activate BIM, this study analyzed domestic BIM standards and guidelines, and defined a working BIM manual configuration system and its detailed configuration method. The findings and improvements are presented as a BIM practice manual on development measures in the road sector. This manual is expected to minimize the repetitive trials and errors and design errors in the construction of road-sector BIM models, to improve the productivity and efficiency in the creation of BIM outputs and their delivery, and to enhance the quality and utilization of the outputs. Further, the proposed manual is expected to provide and share information on the practical cases for BIM, to bolster the capabilities of design engineering, to ensure the linkage with relevant agencies, and thus to expand the diffusion of BIM in a virtuous cycle.

PURPOSES : With the recent change to domestic and overseas construction technologies, which led to the adoption and application of threedimensional building information management (BIM), a BIM output delivery operation system is needed for the civil engineering infrastructure category. This study analyzes the domestic and overseas BIM-order placement, BIM-related guidelines/guides, and the BIM output delivery system for the road construction project category to present guideline development measures for BIM output writing and delivery. METHODS: This study surveys and analyzes the domestic BIM-related research trends to examine the domestic-infrastructure BIM-order placement situations in public ordering agencies. Additionally, it analyzes the domestic BIM-related guides and guidelines and existing twodimensional electronic delivery systems and the domestic and overseas BIM output delivery systems. This study defines the guideline composition system and direction to present criteria for BIM output writing, delivery, management, and utilization in the road category. Furthermore, it presents guideline composition measures for BIM output writing and delivery to propose detailed criteria, output-list composition, and output inspection procedures. RESULTS : This study presented BIM output guideline development measures for planning BIM output writing and delivery and management/utilization measures in the road category. To that end, it determined the domestic and overseas BIM guide and guideline composition systems, BIM ordering criteria, BIM data writing and delivery criteria, BIM output management and utilization measures, and a common BIM output list to present suitable detailed criteria. CONCLUSIONS: This study sought to respond to changes to the domestic and overseas construction environment and to present output writing/delivery guidelines as activation measures supporting the adoption and application of BIM. To that end, we analyzed the domestic and overseas BIM guidelines and guides, task instructions, bid information, etc. to define the appropriate composition system and to give it direction. We defined the contents of tables and detailed descriptions to present guideline development measures for BIM output writing/delivery guidelines in the road category. This is expected to improve work efficiency for BIM and to enhance output quality and utilization. Furthermore, the adoption of BIM in the road category will provide an infrastructure environment with which to exchange BIM information with related agencies. We plant to further develop verification tools for the Ministry of Land, Infrastructure, and Transport's BIM model projects, for their output writing and delivery, and for an integrated BIM platform that will continue to improve the proposed criteria.

This study suggests a safety management model for construction management (CM) suitable to domestic conditions so that inefficiency resulted from the operation of construction projects by public and private institutes according to different systems can be eliminated for the securing of systematic and efficient safety management. Based on the suggested safety management model, this study also develops a safety management information system that can efficiently and consistently manage and maintain a large quantity of information, and give necessary supports in a speedy way in the managing of construction projects.

Construction Management(CM) system, which was introduced some years ago to large national construction projects, such as the construction of Incheon New Airport, construction of high-speed railroad and World Cup stadiums, is considered to be still in its early stage and safety at each step of CM is very poorly controlled. In an attempt to improve such inferior safety control of domestic CM, this study analyzed safety control operation system in CM home and abroad and suggested a model for the construction of safety control management information system suitable to the conditions of Korea.
