The tire production facility is a large-scale construction with the complexity of a manufacturing process. The process utilities should be wide-ranging as an effective arrangement of them is highly important. All the necessary information should be clarified together with the manufacturer at the basic planning stage, and this design should be developed to comply with the local culture and regulations. It is important to carry out more advanced engineering in terms of process, cost and quality, even if it is difficult to standardize due to the cultural and geographical conditions and regulations. The key point is to reflect all the given conditions and make a clear design during the design stage, to eliminate the problems after the construction has begun. Another key point is the delivery system, which must be totally managed from the initial design stage until the construction stage by proven companies. Flexibility, quick action, and single responsibility will be the fundamental features in all the steps of the project.

The BIM simulation systems involve inefficient aspects in delivering real world circumstances because they are operated in the virtual reality (VR) environment without representing the job-site operations. Differently from VR, augmented reality (AR) enhances the reflection of job-site reality to virtual environment. AR influences architecture, design and construction. This reality replaces or merges with the normal physical world and it can be tailored to enhance comprehension for specific design and construction activities. The main objective of this research is to develop an AR-based decision support system for free-form buildings design/construction/maintenance processes. Haewoojae, a free-form housing building built in Seoul area is identified as a model building to generate the system. Seventeen engineers, who are masters or doctorate graduate students at the S university in Seoul and have been working in the Korean construction industry for more than 10 years are invited to validate the system's appropriateness and usability in comparison with its development objectives.

The purpose of this study was to research the characteristics of the pattern design and the weave construction of 67 fashion fabrics in women's Hanbok. All the fabrics were made by 100% silk. Arrangement, size, and the type of patterns were investigated for research of the pattern characteristics. Pattern weave and background weave were analyzed, then the weight and the thickness were measured for studying the fabric construction. The results were as follows. First, irregular arrangement was more commonly used than regular arrangement, and then the complex arrangement and the combination arrangement were appeared considerably because of the existence of the various patterns in a fabric. Third, the types of pattern weave construction were much more than those of background weave construction. This is caused by the expression of dimensional effect for patterns. This survey can be practically used for development of pattern design for Hanbok industry and furthermore it will contribute to revitalizing of Hanbok market to overcome design limit in the future.

In the budgeting guidelines, there are rules for calculating design fee and direct costs. However, only the design fee is calculated excluding the direct cost, which causes the cost to be insufficient. Therefore, this study is designed to analyze representative cases where direct costs are insufficient, draw out problems, and propose a way to improve design fees.

The primary goal of most clothing-related textbooks currently used in colleges in Korea is to determine how to plan and develop basic patterns. Therefore, they are limited in understanding the patterns and sewing methods of practical, ready-made clothes that are continuously being upgraded. According to previous studies regarding sewing methods in clothing construction textbooks, tight skirt, tailored jacket, and shirt sewing methods have been explained. However, there has been no study on the sewing methods of slacks. Therefore, this study attempted to suggest basic data needed for making slacks through a comparative analysis of their sewing methods for educational purposes. In addition, this paper is meaningful in that it complements clothing construction-related textbooks according to the current trends of diverse clothing design and materials and develops learning materials for the construction of clothes, which are applicable to practice. In this study, the sewing methods and construction procedures of slacks stated in clothing construction textbooks that are currently used in colleges and fashion-related educational institutes were analyzed. Among a total of 47 textbooks on the market, 15 books that cover the cutting and sewing methods of slacks and are suitable to slacks design were used. According to the analysis, most textbooks described the production methods only, without explanation of materials, which can affect clothing construction methods. Because there is a large difference in pocket and slacks procedures by textbook, there is a need for a standardized construction method with changes in clothing materials and design.

Recently, the Design-Build (DB) delivery method in public sector makes some argument by reason of the initial cost which is more higher than those of Design-Bid-Build (DBB). According to the results of pervious researches related to the performance evaluation of delivery method, DB can lead the reduction of project cycle time and also is superior to the traditional DBB in terms of construction quality. The performance on each delivery method could be generally evaluated by a project cost and a project cycle time as one of quantitative analyses, and also by construction quality as one of qualitative analyses. In most researches, the evaluation of performance level based on delivery methods has been evaluated by the degree of their satisfaction through the interview with owners. Therefore, this paper analyzed the design documents of construction projects delivered by traditional DBB and DB in bridge construction projects in order to measure design quality, constructability, maintainability, and etc. As an above-mentioned analyses, finally, this research shown that how much the difference of performance level is by each delivery method.

Although the importance of creative thinking is rapidly increasing in the new century, the generation of creative ideas and its application in the construction industry have been considered relatively difficult. Thus there have been a few studies on the subject that how to apply creative thinking tools with empirical evidence in the construction industry. Value engineering(VE) has been widely applied in the design phase of construction projects due to the government regulation, Brainstorming has been the most prevalent idea generation techniques in the VE activities during the past several decades. Contrary to popular belief, the performance of brainstorming is not so good. It is known as the brainstorming myth. This paper proposes the business creativity codes(BCC) as an alternative idea generation tool in the design phase VE of construction projects. In order to examine the effectiveness of the BCC, 50 successful field cases awarded in the design VE competition of government agency are used. The result shows that the BCC can be used as an effective idea generation tool in the design phase VE construction projects.
