In this paper, we propose a novel method for converting the existing 2D processes in the design and construction phase of civil engineering, to the future BIM-based processes. First, we compare and analyze the actual application processes of the outputs of the existing 2D method and the outputs of the 3D BIM method, for the whole process of BIM design of earthworks and road structures and integrated utilization of quantity, process(4D) and construction cost(5D), in view of life-cycle. The proposed method acquire the outputs of the design phase integrating IFC international common standard file information and CBS/OBS/WBS standard classification scheme information, and acquire the outputs of the construction stage by using an integrated utilization module for quantity, process(4D) and construction cost(5D). Ultimately, we intend to commercialize the step by step technologies for BIM design and construction in civil engineering by using the proposed method.

The national government is pushing hard the adoption of the BIM (Building Information Modeling) technology in the construction industry. The BIM application provides a visualized environment where the construction manager can inspect the structure of buidling structures. The application also provides information on activity progresses as well as earned values. However, BIM is mostly applied to visualize a structural object with definite forms. The BIM technology needs to be extended to include an object with non-definite forms such as earthwork operations. The objective of this study is to present a prototype of earthwork BIM in the construction operation. The prototype has been built on the attributes of geological information, construction equipment and positioning. The prototype of earthwork BIM shows a 3D graphic simulation of construction equipment moving around for digging and loading.

Many research and case study for BIM have mainly been focused on architecture domain. However, it is insufficient to civil engineering domain. Although BIM will be applied to civil engineering domain. because national BIM standard and delivery system of BIM is not ready, these demands are increasing. First of all, this paper analyzed the current status of the IFC international standards and BIM of civil engineering domain. Second of all, we established the roadmap for BIM development for civil engineering domain. And this paper studied on the BIM application of road construction for a step by step development of civil engineering. Finally, we conduct case study about road project by applying to construction information classification.

The purpose of this case study is to reduce the flaw and reconstruction occur at the level of construction by determining the propriety of estimate and error on a drawing and specification at working design level through case studies of BIM application at the level of design review. As a preliminary to apply BIM technology, it is needed to review the drawing, and then it is required to define BIM range by selecting the section in which construction error occurs frequently except for the type of part that is constructed repeatedly. At the execution level, the drawing is reviewed vertically, horizontally and spatially by proceeding structure and finish modeling on the defined BIM range, and also the propriety of estimate and error on the drawing and specification are examined. We aim to raise the completion rate, improve quality of construction, reduce the cost for construction and shorten period of construction by preparing for the error on the drawing and specification in advance through this review procedures.

These days Construction Industry is one of the major industry in public project and it has many problems. And Construction Industry highly respond to a chage of IT, politics, economy, domestic and international situation. And it causes an uncertainty in Korea economy. The goal of this paper is showing the efficiency application of BIM in Public Project. And this paper follow three steps. First, these day's trend of BIM and delivery method are researched. Second, major factors are thrived to appreciating BIM Third, delivery method based on BIM is proposed. Major factors of delivery method are researched to make guide line of delivery method in public project in the future.

Overseas countries' government and facility management industries make efforts to ensure precise and fluent data from building information modeling (BIM). In facility management, a large amount of data and information are necessary to continue the process activities. Facility condition assessment, which is performed to make budget plan for the maintenance and operation requires the related facilities' documentation and information. However, it depends on the owner and the user of the facility to provide accurate and complete information to consultant. The problems as follows: (1) owner and user should provide documents and information, and (2) the consultant cannot verify the provided information. To solve these problems, we suggest a methodology to produce the information for FCA through BIM. First, all of the essential documentation and assessment elements are listed. Next, the documents and elements are separated out, whether they are able to be extracted from BIM or not. Then, the list indicates only the data that is linked with BIM. The suggestion is expected to provide the required information through the connection to BIM with accuracy and completeness and to present another BIM application use for facility management.

BIM (Building Information Modeling) is a new paradigm that includes construction life-cycle, and BIM has become mandatory regulation according to the Public Procurement Service since 2016, which accelerates its application. BIM is now expand from architectural field to infrastructure industry. Through pilot projects, BIM has been challenged with verification process. This trend has affected to maintenance and operation (M&O) phase of construction life-cycle. Advanced country has already published their research and result with feasibility study and guidelines. In this paper, we conduct the feasibility study to adopt BIM-based infrastructure management system. Bridges and tunnels were selected as application target, and benefit/cost ratio were used. The result shows that BIM-based infrastructure management system is feasible when the level of detail is more than "Medium" in bridge, and "High" in tunnel.

This study aims to study IFD based IFC application, and API technology were examined for extending $IFC2{\times}4$ information by using IFD libraries. According to this, information exchange scenarios for Open BIM were established with IFD application. And necessary standard elements for introduction of IFD were introduced and the templates of object and property information were suggested for realization.

Nowadays, BIM(Building Information Modeling) technology has been slowly accepted and developed around the world, making smart construction possible. Many countries are also actively promoting the comprehensive application of BIM and changing the traditional construction methods of the construction industry. This study reviews foreign and domestic literature reviews on BIM application barriers and smart construction applications, providing a theoretical basis for Chinese construction enterprises to reduce or eliminate BIM application barriers. Based on the common feature of policies or strategies that promote the development of smart construction in developed countries, such as the United States, the United Kingdom, and Singapore, the deficiencies of China's smart construction policies for construction enterprises are analyzed. Moreover, according to the literature review of the development status of China's construction industry, the SWOT analysis matrix of China's smart construction strategy is obtained. Finally, based on the SWOT matrix analysis results, combined with the development status of China's construction industry and the obstacles faced by smart construction, the portfolio strategies and recommendations for the development of smart construction are proposed in this work. These portfolio strategies and recommendations can provide a reference value for construction enterprises.
