Large spatial construction needs to consider various construction management factors through the construction guide, including high-tech roofing works for creating large space without columns and erecting large spatial structure. However, the domestic large spatial construction relies on overseas construction technologies due to the lack of construction guide of large spatial construction and experience in similar type of project. To improve the problem, we deduced principal items of construction management considering characteristics of large spatial construction as a preliminary study for developing a construction guide.

Noise and vibration occurs during construction intermittently, but with the most arise complaints. There is a need to efficiently manage the construction noise and vibration problems because in case a residential facility that requires calmness around the construction site adversely affects the living conditions of nearby residents. The ministry of environment has mandating the installation of soundproofing facilities for the management of construction noise. In order to enforce a particular construction, the mandatory install with soundproofing facilities before the start of construction, and after construction. However, Installation guide of soundproofing facilities for construction sites were not considered affected areas by noise and there is no provision of performance evaluation for soundproofing facilities. In this study, investigated the status and problems of the installation guide for soundproofing facilities in construction sites, we propose an efficient installation guide of soundproofing facilities for the reduction construction noise.

The number of high-rise buildings has increased year after year, with there currently being 5 projects in progress to construct buildings higher than 100 stories in Seoul alone. The construction cost for such high-rise buildings is significantly higher than the cost for a conventional low-rise building, while maintenance costs are expected to be two to three times higher. To reduce the maintenance cost of a high-rise building, there is the need for a guide rail to be used for maintenance, which is why there is the need for research on the guide rail system. For this reason, as preliminary research to develop a guide rail, this study aims to derive the factors increasing construction cost by taking the installation of a guide rail into account. This is expected to lay the groundwork for the design and construction of guide rails for high-rise building maintenance.

As one of the most important vertical transportation equipment in super high-rise buildings, the construction elevator directly affects the project period, cost, and effectiveness. The paper proposes a new construction elevator with single-guide rail and multi-cages. It can solve the problems of single construction elevator capacity shortage and efficacy decrease with height reduction, the occupancy of plan and elevation position of multiple construction elevators, and extension of total construction period by cycling operation of multi-cages on a single-guide rail. The paper focuses on the design and research of the main components of the equipment, such as the rotating guide rail mechanism, vertical bearing mast tie system, segmented electrical power supply system, group control scheduling system, and safety anti-collision system.

The Korean government makes an effort to raise the competitive power of nation through CM activation in the construction industry. Since the first CM service was applied to the atomic power plant project in 1986, the number of CM contracts are continuously being increased and will be up to 20% by 2002 in public sector. However, the public projects had been executed without any procedure manual or standard guideline of CM services. Meanwhile the Ministry of Construction and Transportation issued $\ulcorner$CM Service Guide$\lrcorner$, but the guide shows an indefinite description in the responsibility, authority and scope of activity for the project participants. Therefore, it is required the procedures be improved and scope of activities be established for the project participants. This study was generated from the comparative analysis of $\ulcorner$Standard CM Services and Practice$\lrcorner$ Published by CMAA and domestic $\ulcorner$CM Service Guide$\lrcorner$ and the case of Incheon International Airport construction. The purpose of this study is to provide the fundamental data for an improvement in the procedures of project execution and the construction manager's activities/rolls shown on $\ulcorner$CM Service Guide$\lrcorner$

The application of knowledge management concepts as a way to improve project success is an emerging topic for project management researches around the world. The Construction Extension to the PMBOK^® Guide Third Edition documents the knowledge and practices that are generally recognized as good practices for managing engineering and construction projects. However, it is not unusual to see that engineering and construction projects suffer from poor performance. Based on a critical literature review, a theoretical framework is developed for the application of knowledge management in engineering and construction projects. This framework is subsequently applied as a lens to examine the construction extension to the PMBOK^® Guide, aiming to identify the key characteristics of knowledge management in this standard. This research also aims to highlight those aspects of the construction extension to the PMBOK^® Guide that can be improved from the knowledge management perspective. Recommendations are made to improve this standard by means of applying knowledge management concept so that better project outcomes can be achieved.

General criteria for the quality of porous concrete have not been established yet in Korea. And yet, pavement and construction have been performed. In this paper, guidelines on the construction site quality control of porous concrete were developed in order to establish criteria for resolving the issues and problems of porous concrete, to establish methods for improving poor performance, and to manage porous concrete more systematically. In addition, a guide for the construction site quality control of porous concrete, which was appropriate for reality, was developed by researching several quality control guides and maintenance at construction sites. The guide consists of a total of nine chapters such as Application Range, Overview, the Structure of Porous Concrete, the Design of Package Thickness, Package Materials for Porous Concrete, Construction Methods, Quality Assurance and Inspections, Construction Site Quality Control, and Maintenance. It describes quality control guidelines in all steps such as methods for transporting porous concrete from the factory to the construction site, cautions for construction work at construction sites, maintenance, and management. The Guide for the Construction Site Quality Control of Porous Concrete is expected to ensure the quality of porous concrete, to reduce national costs for quality assurance, and to help ensure the health and safety of Korean people.

The railway structure for a rubber-wheeled automated guide-way transit system consists of a driveway and a guide-way. The most important factor of this system is the driveway and the guide-way aligned with each other, especially for curves and inclines section. The conventional construction method caused many problems such as discordancy by constructing the driveway before constructing the guide-way. Therefore, in this paper we introduce a new method of constructing a railway for a rubber-wheeled light rail vehicle; the new method of constructing the guide-way beforehand as a preceding process. The new method for AGT railway system can simplify the construction process and thus the construction costs may be reduced. It should also improve the driving performance and the comfortability in operating of a light rail vehicle.

Nowadays the Project Management is increasingly adapted into almost all the fields in business management processes among leading companies both in Korea and overseas. However its actual practices are rare to be found. Among the Project Life Cycle, this report covers the real cases of the PMBOK knowledge areas in NPP Architect Engineering. The areas of the Construction, Start-up and Operation will be exception of the cases. By way of analyzing the KEPCO ENC's Processes/Procedures/Systems and the ones in PMBOK Guide, this report will show the contents in the PMBOK Guide is rather practical than theoretical. Meanwhile, implications whether the conclusions of this report might be applied to other industries such as general construction, non-nuclear plants, etc. should be left behind to follow-up studies.
