Construction project has been changing a huge size and the complicated, so information of each parties are overflow. For more successful construction, more communications are required. Nowadays, BIM has been used widely to solve the problem. But BIM information is used by attribute parties. Many of parties cannot use BIM information. Therefore, this study's purpose is to develope prototype of BIM usage for tower crane. It will overcome current information dividing.

최근 우리나라뿐만 아니라 전 세계적으로 고층건물의 규모가 점점 커짐에 따라 고층 건물은 초기단계에서부터 막대한 자원과 비용이 발생하고 도중에 설계변경이 어렵거나 불가능한 경우가 많아졌다. 때문에 초기구조설계과정과 실시설계, 시공과정에서의 차이를 최대한 줄이는 것이 사업의 경제성을 좌우할 만큼 중요한 비중을 차지한다. 이러한 정보를 제대로 관리할 초고층 BIM 정보환경이 구축된다면 발주자 설계자 시공자가 얻게 될 이익은 결코 적지 않을 것이다. S-BIM 프로세스 상에서 철골조를 형성하기 위해서는 세 단계의 프로세스를 거치는데 구조 해석 및 설계 단계, 구조 해석 및 설계 결과 데이터베이스 구축, 철골구조설계 및 형상화 모듈에 의한 부재 생성이다. 본 연구에서는 구조해석 및 설계(Analysis and Design, A&D) 데이터베이스를 C#코딩을 통해 형상, 길이 및 위치 정보를 결정하는 데 필요한 정보를 모듈 상에 불러오고, 이를 이용한 부재의 치수, 길이, 좌표 값을 산정하였다. 모듈 결과 생성된 정보를 BIM 플랫폼 상에 모델링함으로써 사용자 입력 값을 최소로 하여 기존 BIM 플랫폼의 모델링 방법 대비, 생산성이 향상된 철골구조설계의 자동화를 구현해 보고자 하였다.

BIM technologies store, share and integrate the information produced in each sector of the construction industry. From this point on, it increases the efficiency of the work. Currently, quantity take-off and process schedule are derived separately based on BIM technology. When calculating the quantity by process, relevant information shall be collected, reinterpreted, and reevaluated as required by the practice. The purpose of this study is to develop an integrated process and quantity management system through BIM collaboration and to build prototypes for steel structures. The main research is to build a construction BIM model for steel structures and a process BIM model through BIM collaboration. Furthermore, necessary information was selected and processed according to the user's needs for integrated management. Relevant integration outcomes are visualized graphically to maximize utilization. Through these studies, a system for integrated control of processes and supplies is provided, and the results are expected to contribute to the improvement of working efficiency and are easily and quickly reflected in design change and process change. In this study, we intended to enhance the usability of information by linking process schedules with quantity calculations based on BIM. Thus, the process for integrated control of the quantity of structural components by process unit and the BIM based schedule information was established. In addition, the efficiency of the information link of the integrated management system was considered for design changes and process schedule changes.

Construction project has been changing to a huge size and speed of construction industrial environment rapidly, therefore construction stakeholder's cooperation is being important. Nowadays, BIM has been used widely to solve the problem. But, the part of equipment planning, the most important part in the actual construction, is lack of studies and information. Therefore, the purpose of this study is to analyze previous BIM tools and research a method to improve affection of information by using BIM equipment database.

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.

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.

The construction progress control is very important because there are many unexpected factors affecting time schedule delay and cost overruns. A complicated measure including item quantity and inherent time and costs is used to monitor the progress. Another element to be considered is a productivity, which is cost effectiveness because productivity is primarily measured by the costs. Productivity is stated as constant in-place value divided by inputs such as worker-hour. The main purpose of this paper is to analyze the productivity of structural formwork using a 3D BIM. In order to achieve the research objective, an integrated model of a BIM with a daily foreman's report is developed. The quantities being extracted from a 3D model and information are integrated with manpower utilized. The developed model is applied to a case project to measure and analyze the productivity in terms of individual building and work crew team. The results are discussed and further research topics will be addressed.

A conventional Design for Safety (DfS), introduced to eliminate potential hazards in the design phase proactively, has encountered persistent challenges, such as perfunctory risk assessments and hazard identifications based on 2D drawings and inefficient workflow processes. This study proposes a BIM-based approach to Design for Safety (DfS) to address the limitations of conventional methods, aiming to enhance efficiency and achieve practical safety management benefits. The proposed workflow process for BIM-based DfS has been refined and validated for on-site applicability through various case studies, including risk assessments during the design phase and field applications for safety management activities during the construction phase. Specifically, the critical process of risk assessment within the DfS methodology has also been transitioned to a BIM-based approach. This BIM-based risk assessment process has been evaluated through case studies, encompassing safety reviews for structural design, construction equipment operation, and construction methodology with sequence in design projects. Additionally, the proposed BIM-based DfS has demonstrated exceptional on-site applicability and efficiency, as validated by the application of a BIM deliverable embedded in DfS information for CDE-based daily activity briefing, VR-based safety training, AR-based mitigation measures inspections, and other safety management activities in the construction phase.
