  • Schedule management of construction work is important in order to complete construction projects within a given period of time. Many efforts have been made and many tools have been developed in order to manage construction projects by a smart device such as smart phones and smart pads. This research proposed a basic design to manage construction schedules via a smart device using Flash. The interactive and graphic property of Flash enables a field manager to manage schedules easily and efficiently. A basic structure was designed for a user to be able to make and change a schedule by touching the smart device's screen. And a prototype was implemented by Adobe Flash/Flex Builder, it is applied to a sample network in a smart phone.

  • 최근 공정관리를 위한 각종 기법들이 개발되고 있으며, 실질적인 시공프로세스를 구체적인 3차원 이미지로 형상화하여 보여줌으로써, 공정계획에 대한 추상적인 개념 모델을 구체적인 것으로 변환하여 발전시킬 수 있다. 하지만 이는 3D-CAD와 공정프로그램을 연계하여 사용하는 방식으로 사람이 정보를 옮겨주거나 입력을 해야 하는 번거로움이 수반된다. 본 연구에서는 3D-CAD 객체 정보 시스템 활용 및 공정자동생성 모듈을 활용하여 통합DB 구축을 통한 실시간 철골공사 공정관리 시스템 프로세스를 구축하였다. 본 연구는 IDEF0 모델을 이용하여 철골공정 관리 프로세스를 제시하였으며, RFID 시스템 설계를 통하여 실시간 진도관리 및 분석 프로세스를 제시하였다. 이를 통해 예상공정정보의 신속한 생성과 실시간으로 실제공정정보와의 비교 ${\cdot}$ 분석 및 시뮬레이션을 실현하고자 한다.

  • 플랜트공사는 토목, 건축, 기계, 전기 공종들이 연동되어 작업이 진행되는 복합공종이다. 또한 일반 공사와 비교시 매우 짧은 공기에 대규모의 공사를 수행하여야 하는 공정상의 특징을 갖고 있다. 이러한 특성들로 인하여 플랜트공사에서 공정관리는 매우 중요한 요소가 되고 있다. 4D CAD에 의한 공정정보의 시각화는 이러한 복합공정에서 더욱 필요성을 갖게 된다. 본 연구에서는 플랜트공사의 특성을 고려한 4D CAD시스템 기능 구성방법론과 실제 시스템 개발을 시도한다. 이를 위하여 플랜트공사 현장의 공정작업 특성을 분석한 후 4D CAD 기능을 구성함으로써, 기존 시스템에서 시도되지 않은 플랜트공사에 특화된 공정시각화 기능구축을 시도하고 있다.

  • Today's construction is more various and more complex. Because of that, a lot of uncertain factors are occurred and they related uncertain construction duration. For management complex architecture project, importance of construction schedule management also increased. In previous studies, one of solutions to overcome those problems is suggested. It was BIM based construction simulation process which focused on construction schedule and construction schedule management. But latest process had limited point which has no duration estimation function. So this paper suggested duration estimation method and developed duration estimation module. Duration estimation module developed with current scheduling tool MS Project and their macro function. However, this module has just developed Reinforced Concrete Structure and has to do more development and research.

  • The objectives of this research are 1) control of schedule or improvement of management for aerial environment, 2) distribution of responsibility to the parties concerned (factory, material company, construction company, design and engineering, occupancy). The results show the relative priority of the four major items in wall-based apartment buildings and in column-based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows more efforts to improve IAQ are needed in material factories and engineering/design companies.

  • 작업의 지연을 줄이거나 예방하기 위해서는 작업지연상황을 지속적으로 확인하여 작업지연을 야기하는 원인을 찾아내고 대책을 세워야 한다. 건설 프로젝트는 동일한 조건하에서도 주변 환경에 따라 결과 값이 다르게 나타나는 일회성이 강한 분야 중에 하나이다. 그래서 지금까지 이루어진 선행연구들은 작업지연기간 산정방법 또는 작업지연의 클레임 사례에 관한 연구와 프로젝트 종료 후 결과에 의한 원인을 제시한 것이 대부분이다. 따라서 공사 진행 중에 발생하는 작업지연에 대해 체계적으로 활용할 수 있는 분석방법과 절차가 필요하다. 본 연구는 작업지연 원인분석 범위를 프로젝트내의 현장관리 분야로 국한하고 작업의 투입요소에 의한 분석과 VSM을 활용한 분석으로 나눴다. 건설업에 적합한 원인분석 방법을 제안하기 위해 기존에 활용되고 있는 분석방법의 특징을 분석하고 건설업의 특징을 분석하여 건설업에 활용이 적합한 방법을 도출하고 절차를 제안하였다.

  • This paper presents a system called a Cash-flow based Construction Schedule Optimization system(CfSO). The existing CPM effectively handles schedule and cost management. However, funding strategy should be considered to obtain maximum profit and to progress a project favorably. One of measures is to coordinate the contract terms between owner and subcontractors (or suppliers). Contractor may decrease the interest cost attributed to project financing by adjusting the timing of cash-inflows and cash-outflows. It is an excellent method maximizing profits. This paper presents a method to estimate the amount of a cash-flow occurred periodically by integrating the terms of contract into scheduling. The proposed method is implemented as a system prototype in Microsoft Excel. This system provides a user an automated tool that identifies an optimal schedule that secures maximum profit by adjusting start and finish times of non-critical activities' free-floats without affecting on the project completion time. This system supports a project manager to establish an optimum project schedule and identifies profitable contractual conditions against to a construction owner.

  • 공정관리분야 전산 소프트웨어는 개발초기의 단순한 일정계산결과 제공에서 기성관리, 진도관리, 자원관리 등의 결과까지 제공하고 있으나, 여전히 2D 개념의 분석결과만을 제공하고 있다. 최근 국내외에서 개발되고 있는 공정관리시스템은 기존의 2D 공정표 (시간)와 3D 도면 (공간)을 연계한 4D 개념으로 발전되고 있다. 본 연구에서는 4D 시스템의 기본적 접근이론과 현재까지 개발된 대표적 4D 시스템들의 주요 기능분석을 통하여, 현재의 4D 공정관리시스템이 갖고 있는 활용상 문제점과 향후 개선방향을 분석하였다.

  • The image data of the web camera is used to identify the construction status of the site in a remote office and it can be used for safety management. This study develops a construction schedule simulation system based on the active nD object linked with real image data of web camera from the construction site. The progress control method by 4D object uses a method that the progress of each activity is represented with different colors by progress status. Since this method is still based on a virtual reality object, it is less realistic description for practical engineers. Therefore, in order to take advantage of BIM more realistic, the real image of actual construction status and 4D object of planned schedule in a data date should be compared in a screen simultaneously. Those methodologies and developed system are verified in a case project where a web camera is installed for the verification of the system.

  • Simulation applications for analyzing the productivity of construction operations at operation level and project schedules at project level are crucial methods in project management. The application at two different levels should be very tightly linked to each other in practice. However, appropriate integration at the levels is not achieved in that existing systems do not support to integrate operation models into a schedule model. This paper presents a new approach named to Discrete Event Simulation-Nesting modeling approach, which supports not only productivity analysis at operation level but also schedule management at a project level. The system developed by the authors allows creating operation models at the operation level, maintaining them in operation model library, executing sensitivity analysis to find the behaviors of the operation models when different combination of resources are used as existing DES systems do. On top of the conventional functions, the new system facilitates to find the optimum solution of resource combinations which satisfy the user's interest by computing the hourly productivity and the hourly cost of the operation. By drag-and-dropping an operation model kept in the operation model library, the operation models are integrated into an activity of the schedule model. When a complete schedule model is established by nesting operation models into the schedule model, stochastic simulation based scheduling is executed. A case study is presented to demonstrate the new simulation system and verify the validity of the system.
