The nuclear power plant(NPP) construction is a mammoth project, which requires a huge construction budget and the long construction duration of about 7 years. Recently there is a trend to shorten the construction period, to save the construction cost and to ensure the competitiveness through adopting the open top construction method. In this method, the major equipment are moved into the building through its top, and the internal works of the reactor building are being in process without installation of a dome roof.

This paper describes how using the XPS Document technologies of Windows Vista support and enhances interactions with the structural design and construction process. It illustrates the document workflows and the document life cycle in a typical construction base knowledge system. It provides engineers and decision makers and implementers with information about this new technology and how they can apply it to their design and construction models. The paper also highlights opportunities for the new format of data exchange in the recent efforts to develop National Management System Standards for Transportation Applications to benefit from these emerging technologies.

Design changes are inevitable areas of work for construction engineers as they occur frequently in the construction site, and are becoming a technical measure of the technical person to the design change. In this study, the purpose is to analyze by comparing the availability of excel and the enscised program during design changes through the case, and to present the efficiency of the the Cost-of-construction Program.

For this study, a series of interviews with engineers in the Korean construction industry was carried out through a formal workshop format to analyze the causes of the inferior quality of builders' hardware. The authors established the causes of defects in window hardware construction in relation to the three aspects of system, design, and construction as involving the following seven factors: lack of system (including low ability to create construction specifications); low social awareness of the importance of window hardware; low technical capability to create design drawings; low design costs; small manufacturing capacity; low construction cost; and short duration of construction. Among the seven causes, the biggest cause of defects in window hardware construction is the lack of a system (low ability to create construction specifications), followed by low technical capability to create design drawings. In addition, this study carried out basic research to create measures to prevent defects in window hardware construction by analyzing how such causes of defects are distributed depending on the scale of architectural firms and construction companies during actual projects.

By prosperous condition of construction economy in the early 90s in Korea, the government 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 systems(AES) in 1995 that give the authority of principal engineers to the admitted engineers who do not take the written examination but have equivalent working experience. Since 2000, professional $engineer^{\circ}{\phi}s$ shortage has been resolved. however, the opposite situation, which is serious over-supply of construction engineers has occurred. Thus, Government announced that would abolish the admitted engineer systems as recognized the existent admitted engineers(about 1,000,000 persons) from 2007. However, Professional Engineers Institution has strongly insisted that Government should not recognize existent admitted engineers. 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 principal $engineer^{\circ}{\phi}s$ supply change by admitted engineer system abrogation and suggests the idea to regulate the supply and demand with the improvement of the regal system.

After the introduction of Professional Engineer System to secure superior technical personnel in 1963, the engineering license regulations were introduced in 1995 - the person qualified with either the academic back ground or career in the construction field can be authorized as a construction engineer- to cope with higher demands for construction engineers caused by revitalization of construction business such as 2 million house construction. As a result, the number of construction engineers has been increased drastically since year 2000, which caused serious problems in utilizing top technical certificate, the PE's. Recently, relating to the opening of technology market according to WTO agreement and mutual authentication among countries and etc., the government is preparing legal and systematic foundations to guarantee the professionalism of engineers. Through the exact supply-demand forecast of PE's reflecting these systematic aspects, we are going to analyze the problems in the supply-demand of PE's and suggest the systematic improvement plans for managing the supply-demand of PE's. The result of this research can be used for building efficient and consistent raising and utilizing system of PE's as well as supply and demand system of qualified PE's

Mechanical facilities in modern buildings and industrial plants become more important in the view points of energy and environment issues. However, mechanical construction fields are still considered as to be subjected to buildings, even though design and construction of mechanical fields in the construction production process is independent of other fields. Recently, 'Framework Act on the Construction Industry' has been revised since 2007. According to the revision, the barrier of general construction and specialized construction is collapsed and the construction company can register any type of construction classification if they are able to carry out the construction mission. The mechanical construction fields are exempt until 2011 because of the protection of mechanical construction industry. In the present study, the bidding system has been prospected due to the revision of 'Basic Law on Construction Industry' after 2011. The trends for development of mechanical construction fields has been also discussed.

The deduction methods for forced displacement depths caused by sea dike construction often assumed the shape of forced displacements and heaving. To investigate the shape of forced displacements and heaving, a model tests was performed. Results of the tests are as follows; 1) The shape of forced displacements can be assumed ellipse. 2) The shape of heaving can not be assumed uniform shape like a circle and Extents of heaving was varied with the loading height and width. 3) The shape of forced displacements caused by step construction, pebble embankments and soil embankments, also investigated.
