The planning stage of an architectural project has much more significant effects on the cost or outcome of the project than other stages of the project. In addition, the importance of architectural planning has been further increasing according to the recent trend of construction projects becoming larger in scale and more complex. In spite of this, the current situation is that the planning stage work is not being systematically managed. Accordingly, the purpose of this study was to develop a BIM-based simulation system for providing support during architectural planning stage such as spatial planning & review, cost review, project owner requirements management, etc. It is easy to review various alternatives using this system that allows not only the modeling of space object modeling but also the instantaneous review of spatial area & layout, cost, etc. based on object information. In addition, it can be used as a communication tool with the project owner as it provides the visualized information and quantitative data of the building model, and the information created through this system can be delivered to the following stage for usage. It is thought that using this system, the entire project work including the architectural planning stage can be supported and even contributing to the advancement of architectural process.

Schedule management is one of pivotal project success factors during construction projects. However, there are many difficulties in rapid scheduling and controlling since the existing planning techniques require considerable amount of manual work and manager's judgment in a construction project. This research aims to propose a new scheduling method and algorithm for automating and visualizing the planning process, which is called Countable-grid scheduling method. In this method, if the scope of work is defined via a visualized tool, the schedule plan is created automatically according to the productivity and workable conditions of each activity. The location of the work for each date can be visualized in grid-based approach. Moreover, the work schedule can be updated automatically according to the progress. The industrial applicability of the proposed method was verified in construction projects via case study with sample data. This research can contribute to the construction industry by automating the construction schedule management process.

Recently, research on the application of BIM has continuously been active not only in architecture but also in civil engineering in order to improve work efficiency across the project's planning, design, construction and maintenance phases. However, the empirical applications of BIM targeting to civil engineering scope of construction sites still lags compared to architectural sized projects. This is because BIM tools are mainly based upon vertical structures of architecture, thereby most of them have difficulties and limitations to get utilized on horizontal structures of civil engineering. Therefore, this study intends to propose automation technology of design using BIM library and to indicate its field availability through case application on a railway project representing linear infrastructure. In addition, it put forward the utilization plan of the automation technology upto 4D and 5D by continue making use of the BIM model created in the project's design stage up through the maintenance stage. The novel method of the technology proposed in this paper incorporates the automatic creation of the BIM library based on two-dimensional tunnel cross-sections and sweeping of it over three-dimensional alignment to create a BIM model of linear infrastructure. The proposed technology is anticipated to improve the efficiecny of modeling process of railway projects based on linear structures.

This research has its objective in searching for a management plan that is stronger than existing plan for the regional development project in time for the execution of "Regulations on Regional Development and Support". Accordingly, the following plans for improvement are suggested to make improvements in lack of regional development projects management awareness; absence of integrated management system; and lack of reliability in project management information. Firstly, the management of regional development project needs to be operated as a system for project evaluation management based on related legislations. Secondly, various information of regional development project should construct a database, which becomes an information system that can be utilized by the central government and regional governing organizations. Third, to promote efficiency in regional development project management and expertise, it is necessary to prepare a project management system utilizing professional outsourcing organizations and such. Lastly, it is necessary to improve the work environment to enhance the expertise and the responsibilities of those government officials in charge of the project.

A general practice in software ordering behavior in public sector has been an enormous obstacle standing in development path of Korea's software industry. Standard on software development cost estimation is supposedly based on Function Point, but in general, it is on headcounting (a number of people involved in a project). Moreover, it is difficult to change a contract in an on-going project, since statement of work is not precisely and carefully described. But it has a simple solution. Design and Implementation should be a separate project, as in construction industry, and both power and responsibility for design should be given to an expert with a national-level qualification. Here, there is a simple way for Korea to reborn as one of the strongest software country.

This paper presents an automated construction quality nonconformity control method. Existing quality control process are confined attributed to the dependence on human quality personnels. They are inefficiency for continuos quality improvements and may cause project schedule delays when any nonconformity is handled timely fashion. For sure, It is important to identify the add hoc quality nonconformity control processes and to implement them into an automated system that controls its' work-flow. It would be desirable to develop the construction project quality nonconformity control system using Building information modeling(BIM) and Information and Communications Technologies(ICT). It may provide an effective platform to prevent quality issues that exist in the existing quality management practice.

The completeness appraisal of software is performed in various forms, such as assessing the completion level in the development process, calculating the defect rate, estimating the development cost, and calculating the redevelopment cost. Along with this, the problem that is often dealt with is estimation of the development time. Even in a dispute over completeness due to delays in software development, issues of calculating an appropriate development time required to develop a delivery software or a development time required for change requests are often included in the appraisal request. In this paper, we introduce the procedure and method for estimating the appropriate project time of software development so that the appraiser can be applied to the appraisal work for determining the completeness. The method is based on the manual for calculating the appropriate project period of software development project.
