The project management information system (PMIS) has recently been developed by using the information technology(IT) in order to implement advanced information management technology to construction industry in Korea. The PMIS has been applied not only to domestic construction projects, but also to some overseas projects executed by Korean construction companies. This study was performed to develop the PMIS that is tailored to the US construction IT market. It has been monopolized by the US-based IT companies, but other companies are recently emerging with competitive technology and market strategy. As a preceding study, existing commercially available systems were analyzed, and the required features of the PMIS were identified by analyzing the core elements of contract, process and cost management about construction projects in the US. Then, the PMIS was developed based on the aforementioned analysis results. The system includes the document management module with an internal electronic approval system, the cost-plus-based automatic labor cost calculation module, and the progress management module to support the integrated project cost management. In addition, the functionality of the developed system was verified by experts about construction management in the US via questionnaire survey. The developed PMIS, in this study, is expected to be applied not only to the US construction IT market as a system specialized for the US construction industry, but also to other oversea markets in the future.

The APR1400 (Advanced Power Reactor 1400MW) nuclear power plant is a large-scale national infrastructure facility with a total project cost of 8.6 trillion won and a project period of 10 years or more. The total project area is about 2.17 million square meters and consists of more than 20 buildings and structures. And the total number of drawings required for construction is about 65,000. In order to design such a large facility, it is important to establish a design standard that reflects the design intent and can increase conformity between documents (drawings). To this end, a design bases document (DBD) reflecting the design bases that extracted in regulatory requirements (e.g. 10CFR50, Korean Law, etc.) is created. However, although the design bases are important concepts that are a big framework for the whole design of the nuclear power plant, they are managed in 2-dimensional by the experts in each field fragmentarily. Therefore, in order to improve the usability of building information, we developed BIM(Building Information Model) based 3-dimensional design bases management system. For this purpose, the concept of design bases information layer (DBIL) was introduced. Through the simulation of developed system, design bases attribute and element data extraction for each DBIL was confirmed, and walls, floors, doors, and penetrations with DBIL were successfully extracted.

Establishing housing supply strategies in Korean housing market is a crucial issue due to contradictory but concurrent two problems in market; one is the unstable working-class residential and the other is the high vacancy rate by the low-level of sales rate. Although government has been continuously implementing various supply policies in an attempt to evenly distribute houses as well as to keep supply and demand in balance, it is difficult to satisfy all of stakeholders, such as housing consumers, housing owners and housing suppliers. This paper, therefore, applies a system dynamics methodology and offers a dynamic and integrated model encompassing for-profit behaviors of each market participants. The proposed model simulates the future trends of house prices, the balances between supply and demand, construction companies earnings and vacancy rate when applying various housing supply scenarios. From the simulation result, recent governmental small-size rental housing supplies in bulks should utilize private construction companies to stabilize housing distribution rate and private supply system as well as the supply and demand are well balanced.

A considerable number of construction disasters occurs on pathway. A safety management in construction sites is usually performed to prevent accidents in activity areas. This means that safety management level of hazards on pathway is relatively minified. Many researchers have introduced that a hazard identification is fundamental of safety management. Thus, algorithms for helping safety managers' hazardous area identification is developed using automated data collection technology. These algorithms primarily search potential hazardous area by comparing workers' location logs based on real-time locating system and optimal routes based on BIM. And potential hazardous areas is filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help improving safety in construction sites.

By prosperous condition of construction economy in the early 90s in korea, we needed a lot of the qualified professional engineers(PE) to manage the construction site. In order to meet the high demand of P.E., government has established the admitted engineer system(AES) which is given to admitted engineer who do not take the written exam but have equivalent working experience in 1995. However, since 2000, while professional engineer's shortage has been resolved, the opposite situation has occurred that is serious over-supply of construction engineers. Thus, government announced that will abolish the admitted engineer systems as recognized existent admitted engineers. However, Professional Engineers institution is insisting that must not recognize existent admitted engineer. From this point of view, it is critical to make the supply-demand forecast systems as a derivative approach of system dynamics also, that is useful in comparing the argument between government and Professional Engineers institution. This paper describes about qualified engineer's supply change by admitted engineer system abrogation and suggests the idea to regulate the supply and demand with the improvement of the regal system.

Knowledge management (KM) has been considered to be an effective means of learning from past projects to effect continuous performance improvement in the construction industry. Despite the growing importance of KM in the construction industry, the usage and effectiveness of IT tools for implementing KM are limited to some extent. Case studies of current KM practices in Korean construction sectors revealed that the chief causes of this problem are the top-down approach of the current practices. To address this challenging issue, this research proposes bottom-up approach, which motivates knowledge creation by shifting the ownership of contents, and facilitates effective reuse of knowledge by providing rich contextual information.

Recently, the construction industry is getting more complex and sophisticated having the characteristics of a mega project. Mega project pursues a value that can't be gained with an approach of seeing a project as just a simple sum of different parts but a mutual combination. Hence to reach the goal, program management is needed rather than project management. program management can be seen as a 'total project management' and for an efficient program management prompt support for decision making is required. However, the current supporting method can't fulfill the requirements, therefore, need a tool to support the decision making and a IETM is expected to take this role. Despite the a lot of expected advantages of IETM, it is still difficult to apply because of the frequent changes of information in specifications and laws. In this research, as part of developing a IETM, we aim to propose a system frame which is based on the analysis of processes of a project. Moreover, based on this frame, a database will be built to contribute towards the application of construction IETM in the domestic construction industry.

The disputes in construction projects are very important issue for stakeholders. However, many of presented claims have not received the compensation money required, and frequently turned down. The most cause is that the claims are not managed systemically on construction. Therefore, it is important to identify which management works are conducted on construction and how significantly do they relevant to construction claim. This research derives key claim management factors through analyzing causes for claim success and failure, and then presents management works relevant to them. This research also proposes the method for effective claim management and its expected effect through expert interview.

In order to achieve the best performance of a project, uncertainties involved in the building construction process need to be identified in the planning phase of the project. Risk management plays a significant role in construction to minimize risk occurred due to uncertainties of a project. Although the importance of the risk management has been known to the construction industry, a more effective system should be developed to meet the demands of the industry. The purpose of this study is to develop the effective risk management system for scheduling the construction processes. The study provides a tool that can optimize the management system which would assist managers to identify schedule risks in the planning phase of the project.
