최근 건설분야에 화두가 되고 있는 건축정보모델링(BIM, Building Information Modeling)은 건설산업의 패러다임 전환을 통한 새로운 성장동력의 미래로 부각되고 있으며, 건축분야는 서울시, 용인시, LH공사 등 BIM을 활용한 공공 발주사례가 확산되는 추세다. 토목분야는 건축보다 기간이 길고 비용이 크며 이해당사자가 너무 다양해서 발생하는 정보의 양이 방대할 뿐만 아니라 활용분야를 다양화하지 못하고 이를 뒷받침해주는 제도나 지침의 부재 등으로 인해 건축분야보다 BIM도입이 늦어지고 있다. 이에 토목분야에서 활용할 수 있는 3차원 형상정보와 관련된 정보모델표준, 지침, 가이드를 개발하기 위해 BIM 적용시 가장 효과가 크고 도입의지가 강한 엔지니어링사의 BIM에 대한 인지도 분석을 통해 토목분야 BIM 도입을 위한 기초자료로 활용하고자 한다.

Earthwork is executed to provide a space for facility structures, and plays an important role in the construction operation. Contractors usually put a combination of construction vehicles to execute the earthwork operation. These construction vehicles need to interface with each other for productivity improvement. The objective of this study is to prototype an earthwork supportive system for information interface between construction vehicles. The study is conducted in a sequence of 1) analysis of information interface during earthwork; 2) data modeling of earthwork attributes; and 3) development of a prototype for the earthwork supportive system. The output screen images of the prototype show that the earthwork supportive system can improve communication between construction vehicles by facilitating information interface during earthwork.

최근 분산된 자원을 효과적으로 공유할 수 있는 그리드 기반의 과학 연구가 다양하게 진행되고 있으며, 그러한 예로 국내에서는 건설 및 토목 분야의 원격실험 관측과 제어를 포함한 공동연구 환경의 구축을 내용으로 하는 KOCED(Korea Construction Engineering Development) 프로젝트가 진행 중에 있다. 본 논문에서는 KOCED에서 구축 중인 실험센터의 하나로써, 지리적으로 떨어진 실험 시설과 수치시뮬레이션을 연동하여 실험할 수 있는 하이브리드 실험센터를 대상으로 데이터 모델링을 하였다. 데이터 모델은 데이터를 표현하는 용어를 통일하고 데이터 간의 관계를 명확하게 하여, 데이터의 재사용성을 높일 수 있기 때문에 실험비용이 많이 소모되는 과학실험에 필수적이다. 그리드에 기반한 하이브리드 실험의 데이터 모델링은, 기존의 건설 및 토목실험의 대부분이 독립적인 실험 형태였기 때문에, 정확한 데이터 모델을 예측하기가 용이하지 않았다. 따라서 먼저 하이브리드 실험의 축소 모형인, 프로토타입 실험체를 만들고, 이에 대한 데이터 모델을 설계하여 토목공학 연구자에 의해 사용하게 하였다. 일정기간 사용기간을 갖고, 이에 대한 회의를 통해 향후 구축될 하이브리드 실험센터의 데이터 모델을 설계하였다. 현재 하이브리드 실험의 데이터 모델을 그리드 포탈 기반의 데이터관리 서비스로 구현 중에 있다.

본 논문에서는 토목분야에 BIM 기술을 적용하기 위해 파라메트릭 모델링 디자인 기법을 기초로 한 토목 구조물 모듈 라이브러리를 구축하고자 하였다. 국제 표준설계방법론에 부합하는 개방형 BIM을 구현하기 위해 표준정보모델은 IFC로 연동하며, 형상 분류체계는 PLIB Part 42(ISO 13584-42)로 정보 분류체계는 Omniclass와 통합건설정보 분류체계를 따른다. 토목분야에서의 BIM 기술은 토목 구조물 표준 라이브러리를 통해 동시공학적 협업설계를 이룰 수 있을 것으로 판단된다.

The purpose of the present study is to suggest the development direction for the neutral library which can describe the parametric modeling and design algorithm to design the construction spatial information which is known as BIM. To do this, we surveyed the recent research related to neutral library and analyzed the library technology of BIM modeler such as Revit, Archicad. By using this result, we suggested the development direction based on BIM description script language for the neutral BIM library including the parametric design and the algorithm definition.

Recently, the interests in three-dimensional design and BIM(Building Information Modeling) are increasing in civil engineering sector and the researches about three-dimensional design and quantity take-off methods for civil engineering structures have been conducted. However, these studies are just carried out the 3D design and quantity calculation of civil structures on the road or railway such as bridges and tunnels. The study on the quantity take-off methods and the evaluation of calculated results on the earth works should be performed in more detail. Based on these backgrounds in mind, the study was conducted the three-dimensional road design and evaluated the quantity take-off results on the earth works using 3D calculation method(average end area method, prismoidal method and composit method). The calculated quantity from composit method showed about 5% error of measuring efficiency than the average end area method, and when reporting the quantity calculation of earth works, it is necessary to specify the calculation method using quantity take-off of earth works.

Recently, as the appearance and exterior design of the construction structure are highlighted, the irregularly shaped structures are increasing in a construction facility. Many softwares provide a quantity take-off function of 3D object under BIM environment, however, they are focused on the limited function based on the solid modeling method. Because the vast geometric information of the curved surface is difficult to extract in the 3D objects that consist of major changes in vertical section shape as the irregularly shaped structures, it is difficult to express a 3D object as a solid model. On the other hand, the irregularly shaped structures can be expressed in relatively free in the surface model because the surface model consists of points, lines and surfaces. Accordingly, the surface modeling method is suitable for the modeling of large irregularly shaped structures. This study suggests a quantity take-off algorithm for the irregularly shaped structures using the surface modeling approach that is beneficial in the design work of structures. Some case projects are used for verifying the accuracy of the proposed method.

The purpose of this study is to propose a guideline to help the client and bidder operate the BIM project in the domestic road field. As BIM design is mandatory in the construction field, documents disclosed by the ordering agency must essentially include procedures and step-by-step requirements to support BIM. The purpose of this study is to propose the structure and components of the guidelines that practitioners need practically by utilizing the currently announced road field guidelines. The guidelines are analyzed based on the procurement documents that were pre-emptively shared overseas, and supplemented according to the domestic situation. Furthermore, the effectiveness of the revised guidelines is confirmed through expert consultation. This study aims to contribute to creating an environment in which construction practitioners who have no experience in BIM project can efficiently carry out BIM projects.

Recently, BIM(Building Information Modeling),which has been an issue in construction work, has been focused on as a new alternative of building industry for way out of crisis by slowing down and decreasing of orders in construction industry. Research for introducing BIM to the architectural field is already proceeding actively at home and abroad. However, civil engineering is so nonrecurring, horizontal, and different from regular construction works that it a large amount of information occurs because of wide range of project, which causes construction firms and design engineers to have some questions whether their initial investment cost would work or not and feel uncomfortable with the cost. In this study, technology level in engineering firms were surveyed for adapting BIM to domestic civil engineering. Development direction of BIM standard information model was drawn through awareness change analysis of BIM in civil engineering, as well. Deduced development direction is composed of guide development, system development, deliverable check and international standard proposal. The outcome will be employed as preliminary data for the study on development of infrastructure BIM standard and deliverable check system in civil engineering.
