BIM(Building Information Modeling) technologies should be applied for the construction life cycle to maximize its efficiency, but the utilization for the construction phase has been significantly lower than that for the planning and design phase. Recently, some of BIM techniques such as 3D design review, 4D schedule management and so on are being introduced for efficient managing to the big national construction projects. In this study, the utilization plans of BIM are presented for the construction phase of civil engineering facilities. The methods of utilization of BIM are discussed for each type of construction, and the techniques applied to the Seoul Subway Lot No. 919 are analyzed for checking the applicability and usability. In particular, a web construction management system based on BIM can help field engineers, headquarters and contractors to use BIM more effectively, and it can be extended to maintenance phase for more efficiencies.

This study aims to investigate and analyze the plan and structural system of 4 kan(間) by 4 kan(間) square church built in early 20th century. At that time, three kinds of traditional wooden structure church had been built under the circumstances of transitional era : Basilica style such as Ganghwa Anglican Church, 'ㄱ' shaped style such as Keumsan Church and $4{\times}4$ Square style such as Bukok Church and Jacheon Church that are concerned in this study. Traditional plans and structural system were mixed with new religious function and transformed into korean peculiar style. $4{\times}4$ Square style is a residual product in that process. Despite of it, little concerns on it till now. The results of this study are described as follows. 1. The plan of these $4{\times}4$ square churches is divided into three areas : cathedra($1{\times}1$), attendance($4{\times}2$), and intermediation($4{\times}2$). The location of cathedra is commonly the opposition part of main gate and projected out of the building. Attendance area was also divided into two, man and woman, because of keeping a distance with each other. 2. The structural system of these $4{\times}4$ square churches are somewhat different because of their size and roof style. In the case of Bukok church, $4{\times}4$ square fall off $3{\times}3$ and $2{\times}2$ gradually and turn into paljak(八作) roof, which enable us to get in traditional entering methods. On the contrary, Jacheon church use hipped roof but almost alike pyramidal roof, which could make us not to recognize entering in the aspect of gable part.

The Treaty of Friendship, Commerce and Navigation between the Chosun dynasty and Japan and the United States of America etc. began signing procedures from Feb. 1876. Thus, Busan port became an open port to foreign vessels in 1876. This has resulted in Busan port becoming the greatest port in Korea. This study explored records which were made by the Chosun dynasty and Japan on the opening and development of Busan port. The results are as follows ; According to making treaties between the Chosun dynasty and foreign countries, Chosun dynasty gradually opened a door to the international community. Various institutions were established in and around Busan port by Chosun and Japan. For example, maritime customs, a court of justice, police station by the Chosun side, a Japanese consulate, the Board of Trade for Japan etc by the Japan side. Records made by or related to these institutions and on the development of the Busan port during the open-port period and the Japanese colonial period were preserved at the Kyujanggak Institute for Korean Studies, the National Institute of Korean History, and the Busan Metropolitan Simin Municipal Library.

In 1996, GS E&C became the first in the industry to adopt a Project Management System using EVM(Earned Value Management) to link schedule with profit/loss. In 2006, the TPMS(Total Project Management System) was completed by adding the concept of Lean Construction and JIT(Just In Time) to the Project Management System. This was done with the purpose of reducing waste and creating optimal work processes. This has been implemented on all sites and has enabled drastic increase of productivity. The portal provides customized information to the client, inspector and subcontractor personnel. Since various parties are receiving information that suits their requirements and is easy to use, usage has increased and since they are on the same platform, quick decisions and information sharing is possible. The purpose of the PMIS's success model in construction projects, this paper tests and proves the TPMS's efficiency and productivity to Dongnam Distribution Complex project.

This study aims to implement an efficient process management system for small and medium sized(local) construction companies and a performance management system for the Korean construction industry. The process management system by Lean Construction is Web 2.0 platform-based and creates clusters with numerous general contractors and sub-contractors, which will enable mutually organic process management. Plus, this system will enable them to compare project performance management by analyzing it during or after a project by collecting and accumulating lots of data occurring in pursuit of a project. These performance management cases will be of help in process planning during similar upcoming projects. This study is expected to somewhat reduce the burden of implementing a complicated process management protocol and system that Korean small and medium sized (local) construction companies experience with their web-based process management, and is supposed to realize accurate performance management with highly reliable data which are significantly accumulated within the database.

For the introduction of the electricity of the special design and supervision system to Protect the faulty-workmanship of the electricity equipment and to reserve the electricity safety, last 1995 "Electricity Technology Management Act" were carried out enactment. March 2002, we introduced the pre-Qualification system that is selected the competent company about the electricity design and supervision service over so much capacity which is ordered by the Public institution such as the nation, local autonomous entity, government investment institute and so on. December 2005, the electricity equipment over so much capacity was taken the housing construction plan's approval by the housing act in case, the municipal or district governor with the authority to approve who selected the electricity supervision company according to the pre-Qualification system. Due to the introduction of the system, we could expect the rights and interests increase of the consumer by eradicating dumping of the close relationship between supervision company and the builder, reduction and concurrent position of the supervisor, according to confirm the quality of the electricity equipment and electricity safety. In spite of introducing of the system, the problems occured as reducing the electricity designer's task range compared with different field, modifing the supervisor's rank system rationally, because of researching about the electricity design and supervision technique lacks. Also, KEEA(Korea Electric Engineers Association) manage the caller of the electricity design and supervisor(company or people), but the problems occured as opening to the public about the curler management, introducing automatic bidding system and We need the solution plan about this. Consequently, we consider the present situation of the domestic and outside and problem about the electricity design and supervision system in this paper, try to present rational operation plan through this.
