The law about floor impact sound goes into effect from March 23th in 2004 and is applying to new designs. According to the new law, the minimal of slab thickness is 180mm by standard floor structure and the new law presents about the minimal standard about heavy-weight impact sound. Also, It presents about classification of light-weight sound separate the minimal standard, so demand of consumers can be accepted. But a working plan of classification about light-weight sound is not presented in accordance with field test, so the problem that design can't be achieved although the aim of design is formed. This study shows contents to investigate for working of classification and will be helpful to designers and construction corporations.

In this paper, systematic analyses for the shoring systems installed to support applied loads during construction are performed on the basis of the numerical approach introduced in the previous study. Structural behaviors require changes in design variables such as types of shoring systems, shore stiffness and shore spacing. In this paper, the design variable are analyzed and discussed. The time dependent deformations of concrete and construction sequences of frame structures are also taken into account to minimize structural instability and to improve design of shoring system, because those effects may increase axial forces delivered to shores. From many parametric studies, it can be recommended that the most effective shoring system is 2SlR(two shores and one reshore)

Defects in apartments, which are one of the major residential types in Korea,produce unexpected inconvenience for their owners. If construction companiespaid more careful attention to the management of defect information, manydefects could be prevented. In this context, this study attempted to derive an improved defect information management system. First, research into cases of defects that were caused by weaknesses in the defect information management system were advanced to confirm the necessity of improving the defect information management system, and as the next step, a survey was conducted to identify problems with the current defect information management system, and the requirements of animproved system. In conclusion, an improved defect information management system will contribute to preventing defects in apartments in Korea.

The design with construction knowledge and experience can eliminate inefficiency in the process of construction and improve productivity in all phase of construction project. To utilize constructability knowledge most effectively in design phase, the information must be made available to the design team at the proper point in time. Current methods for effective utilization of constructability knowledge have focused on the structuralization of constructability knowledge such as checklist, which lack the consideration of the proper point in time. However, constructability knowledge which is used at the inapposite point in time consequently leads to unnecessary rework. To minimize this inefficiency and improve productivity, project manager needs to consider the design process and know what constructability knowledge is required for specific design activities. This paper therefore presents a design process management using Dependency Structure Matrix (DSM) that focus on information flows between design activities and constructability knowledge. We expect that the results of this paper will support that design process management become comprehensive management related to every phase of construction project beyond design review or inspection in design phase, and be used as a basis of the integration of design and construction.

Recent construction projects, characterized by its complication and high-tech, requites highly efficient management efforts. Among others, labor management is very important due to various trades and increasing number of activities. Along with advanced information technology, Web-based construction site management systems are widely adopted in order to improve the efficiency of construction management. However, such information systems have mainly 2 (two) shortcomings. One is that the existing systems were developed and implemented not in subcontractor-centered way but in main contractor-centered way, though the daily construction information is mainly generated, gathered and reported by subcontractors. As a result, subcontractors seldom have access to such information systems. The other is that loss or omission of information may uclw during the information processing process, in which subcontractors have no direct access to such information system. This becomes a major reason of losing the reliability of the information in daily construction report. As a solution for these problems, this paper suggests a Web-based information system that is subcontractor-oriented and also suitable for tact schedule management.

For the past several decades, the residential housing market has been led by construction firms rather than consumers; in essence, it has been a suppliers' market. However, the market is experiencing a transition to a buyers' market, the implication of which is that there will be increased competition among the residential building suppliers. For this reason, it is necessary for construction firms to prepare new strategies to respond to the rapidly changing market environment. Furthermore, consumer satisfaction should be valued more highly than in the past, and should be a baseline in formulating construction product development strategy. For the pre-classified 13 apartment building segments, questionnaire surveys are conducted for the 50 CS (Customer Satisfaction) experts to evaluate their perceptions on the weighing of the quality of each apartment segment. Data obtained from a survey of experts was analyzed from an industry perspective utilizing the AHP technique. Analysis results indicate that the CS experts valued the kitchen & dining area more highly than all other segments. Specific analysis results and implications drawn from the study can be a valuable basis for marketing, product development, and quality management.

Performance measurement and evaluation is a critical issue in public funded civil infrastructure projects in recent years. As a results, Korean government has introduced the related policies and regulations based on the foreign cases to evaluate public construction projects. However, construction circumstances are different from other countries and the results from adopted regulations are not satisfied. Therefore this research proposes the critical success factors(schedule, cost, productivity, change order, safety, quality) for public construction projects based on previous related research outputs to successfully implement construction performance evaluation. Then, this paper also proposes the weights for the critical success factors. The proposed weights are developed by AHP of construction experts. Furthermore, the paper shows the difference of the weights of the critical success factors by project participants (owner, constructor, engineering, and inspector). This efforts will enhance the ability to develop an effective performance evaluation process and system for public construction projects.
