건축 기획단계는 프로젝트 전반에 걸친 주요한 의사결정이 일어나는 부분으로 그 영향력에 비해 프로젝트 정보를 수집, 처리, 저장하여 관련 참여자가 정보를 재사용하거나 참고하여 새로운 의사결정을 수행하는 것이 미흡하다. 따라서 본 논문에서는 BIM을 활용하여 기획단계에서 발생한 정보들이 설계, 시공, 유지관리 단계에 이르기까지 전생애주기에 걸쳐 정보를 통합 관리할 수 있도록 BIM기반의 건축 기획단계 지원 시스템을 개발하고자한다. 선행연구 분석과 이론적 고찰을 통해 건축 기획단계를 정의하고 건축기획 BIM의 개념과 특징을 도출하였다. 이를 토대로 기획단계 BIM프로세스를 정립하여 BIM을 기반으로 건축 기획단계를 지원하는 프로토타입 시스템 VA-Cityplanner를 개발하였다.

The Architecture, engineering, & construction (AEC) industry domains have grown more complex and larger, BIM is a digital representation of a building to facilitate the exchange and development of construction information integration and interoperability. Industry Foundation Classes (IFCs), under development by International Alliance for Interoperability (IAI), represent the part of buildings or elements of a process. IFC has been adopted as a central information repository in order to deliver integrated building information. Other BIM software could open the IFC file, recognize standard objects such as walls, window, and doors as building components. The IFC standard is generally agreed to be of high quality and is widely implemented in software. However, sometimes, information distortion or information toss occurrs during information exchang. The IAI Model Support Group (IAI-MSG) offers the opportunity to certify IFC-compliant applications based on a structuralized approach. However, IFC interoperability error also have occurred by using certificated tools. As project participants exchange BIM information by using BIM software they will need a reliable and efficient exchange of information. In this paper, previous interoperability tests were analyzed, and we propose a new concept in interoperability test.

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.

건설공사 프로젝트는 사전 기획 단계, 설계, 계약, 시공, 운영 및 유지관리 등 각 단계의 다양한 참여 주체에 의해 프로젝트가 진행되고 각 분야 간의 원활한 의사소통을 통한 협력 작업으로 일을 진행한다. 그러나 각 단계별 참여주체간의 협업이 어렵고 정보교류가 원활하지 못한 문제점들이 있다. 또한 건설공정은 현장여건의 변화와 불확실성으로 인해 예측이 어렵고, 보다 신뢰성이 있는 계획의 부재로 인하여 각종 세부 공정들 간의 간섭을 유발하고 계획된 일정을 준수하기 어려워 불필요한 비용의 낭비와 공사기간의 증가를 야기한다. 이러한 낭비요인을 최소화하고 건축 프로젝트를 진행하는데 있어서 효율성을 높이기 위해서는 시공계획 단계의 신뢰성을 높여야 한다. 따라서 시공전의 계획 단계에서부터 4D 시뮬레이션을 통하여 이러한 문제점들을 파악하고 개선하는 것이 중요하다. 본 연구에서는 BIM기반의 시뮬레이션 프로그램의 기능분석을 통하여 효율적인 적용과 발전과정을 알아보고자 한다.

Becoming construction projects larger and more complicated, and utilizing more varied and complex contracting and delivery systems in the industry, integrating information and managing constructability from project inception to completion became the most critical tasks for the successful project management. However, current industry practices of constructability analysis which are too much dependent on field engineers and managers' experiences, are not performed efficiently and also not managed effectively. Then the scope, method, and procedure in performing analysis tasks are not certain as well as not systematic, In addition, due to using 2D based drawings and documents, information required at project phases for the analysis is inconsistent and inaccurate. This study aims to suggest the use of BIM technology and functions for solving various problems of current constructability practices. In particular, constructability analysis tasks performed at design and construction stages are identified and their adaptability, applicability, and benefits of BIM are investigated through interviews on constructability and BIM professionals in the industry.

This paper analyzes the relations between design errors, prevented by building information modeling (BIM)-based design validation, and their impacts in order to identify critical consideration factors for implementing BIM-based design validation in architecture, engineering, and construction (AEC) projects. More than 800 design errors detected by BIM-based design validation in two BIM-based projects in South Korea are categorized according to their causes (illogical error, discrepancy, and missing item) and work types (structure, architecture, and mechanical, electrical, and plumbing (MEP)). The probabilistic relations among the independent variables, including the causes and work types of design errors, and the dependent variables, including the project delays, cost overruns, low quality, and rework generation that can be caused by these errors, are analyzed using logistic regression. The characteristics of each design error are analyzed by means of face-to-face interviews with practitioners. According to the results, the impacts of design error causes in predicting the probability values of project delays, cost overruns, low quality, and rework generation were statistically meaningful.

국내에도 BIM이 도입되어 다수의 프로젝트가 수행되고 있으며 정부에서는 정책적으로 BIM 확산을 도모하고 있다. 하지만 기술적 한계와 이해의 부족으로 인한 여러 가지 부작용이 발생하고 있으며 특히 현재 도입이 가장 활성화 되어 있는 설계 엔지니어링 업무 영역에서 보완이 필요한 부분도 가장 많이 발생하고 있는 실정이다. 이에 본 연구에서는 기존의 설계사례의 분석을 통해 협업 관점에서 MEP 작업요소의 주요 이슈를 도출하고 건축기계설비의 관점을 좀 더 정확하게 이해할 수 있도록 타 공종 기준의 MEP 작업요소 이해를 위한 기준을 제시하였으며 이러한 내용이 앞으로의 국내의 BIM 프로젝트의 수행과 지침의 작성에 활용될 수 있는 기초자료로 활용되기를 기대한다.

As a result, the areas of knowledge that received the highest score in a positive impact were areas of risk management, while those that received the highest score in a negative impact were items of software management. In addition, each project was rated according to the score obtained. The distribution of grades by project was 71% for projects above middle grade and 29% for projects below middle grade. These results show that interest in BIM technology is increasing compared to the past, actual field application and research are actively being conducted, and that real construction sites also enjoy significant positive effects in terms of project management through BIM. In addition, the company is using BIM by applying advanced digital technologies such as AI technology, laser scanning technology and drone technology in line with the era of the fourth industrial revolution. Such a steady progress in future research on BIM technology development will reduce the number of low-grade projects and many middle-grade projects are expected to be upgraded to higher-level ones.

BIM has been increasingly deployed to the construction industry in order to minimize ambiguity and to reduce errors of the communicated engineering information, for which poor communication due to fragmented industrial structure is mainly responsible. Known BIM use cases and related researches are focusing either (1) on a specialized solution for a given specialty area (e.g. structural engineering planning and early design, material take-off, constructability simulation, etc.), or (2) on handling interoperabillty issues with Industrial Foundation Classes (IFC); Neither of these approaches have sufficiently catered for collaboration and information management in actual construction projects. This paper proposes the strategy for BIM+PMIS (project management information system) system focused on improving PMIS which has been commercially provided with ASP(Application Service Provider). It also describes the architecture of the BIM-based information management module prototype, which is a key component of the BIM+PMIS system.

Revit Structure(이하 Revit)는 Autodesk사에서 만든 BIM Tool이다. Revit에 관한 특징은 본 회지 7.8월호에 다루었다. Revit은 현재 국내에 가장 많이 보급되어 있고 관련 서적도 많은 BIM Tool로써 BIM작성, 물량산출, 도면작성 등을 수행할 수 있다. 지금까지 많은 프로젝트가 Revit으로 수행되었고 사용자도 많다. 그럼 7 8월호에 제시한 구조BIM 프로세스에 따른 간단한 설명과 Revit을 통한 BIM작성에 대해 소개하겠다. 자세한 내용은 추후에 BIM교육에서 다룰 예정이다.
