Both competent authorities and private entrepreneurs face plenty of risks when negotiating BTO(Build Transfer Operation) methods of PPI(Private Participations in Infrastructures) projects. Also, success and failure of projects largely depend on the concession agreement contract. In this study, for more efficient negotiation, major issues are examined, and quantitatively analyzed to find out not only the relationship but also the characteristics of which these issues share. Questionnaire research was conducted through both research and by experts who were divided into an ordering agency, design company and constructor. Characteristics of major issues were quantitatively analyzed using the Likert index method, ANOVA(ANalysis of VAriance) and AHP(Analytic Hierarchy Process) analysis. Case studies were examined in order to estimate construction cost, rates of return, government finance support, level of operation-revenues guarantees, estimating operational costs and usage fees. With these 6 items, relative priority, relative impression which is sensible to risk and extent of difficulty in presenting data which is objective were quantitatively analyzed by the ordering agency, design company and constructor groups. From the analysis, there were some similarities between the design company and constructor groups while there was less of similarities between the ordering agency and design company or constructor. The government is diversifying the methods of project promotion, and PPI project from infrastructure-centered to public culture facilities are being expand. The current study will provide not only supporting efficient negotiation but also revitalizing PPI projects.

Construction Projects have many participants by characteristic, scale and contract. Those also have complicated communication structure. So, claim and dispute occur continuously for conflicting communication. In many claim and dispute cases, it usually occurs between builder and owner. Unfair practices by owners position cause main claim and dispute. This study analyses judgment type, cause and compensation ratio in korean commercial arbitration case and provides the dispute information for builder that has weak position by contract. It draws analysis information for managing and controlling dispute that order type, judgement type, cause and failure case. Using these analysis information, it hopes to help inducement of dispute agreement and save time and economic damage for builder during construction. It also hopes to rise construction completeness by providing dispute management information.

Chinese construction corporations take more market shares in the global construction market. The performance of Chinese construction corporations need to be reviewed from the capability and qualification system of the engineers including supervision engineer. The purpose of this study is to analyze the characteristics of professional qualifications for supervision engineer in China. The research methodology is to investigate the qualification exam system, process and examination subjects for searching the fundamental body of knowledge about supervision engineer qualification. The results shows that the qualification system in supervision engineer are classified in detail for the body of knowledge and operated by the government. The qualification examination requires broad and defied knowledge structure together with practical experiences. The research results may lead further research subjects of Chinese construction related qualifications and education system in the ways of more specificity, expertise, and practicality. The mutual understanding of qualification system becomes major issue to build better collaboration in global market.

이번 회 및 다음 회 두 회에 걸쳐서 파라메트릭 툴이 건축 설계 및 시공 과정에서 디자인 툴로써 뿐 만이 아니라 설계를 진행하기 위해 주어진 설계 초기 조건을 분석하는 과정 및 시공과정에서의 시행착오와 오차를 줄이기 위한 pre-construction 등에 다양하게 사용되는 경우를 살펴보도록 하겠습니다. 본 프로젝트는 SHoP Architects에 재직 당시 작업하였던 Barclays Center의 Green Roof 프로젝트이며 경기장 안 이벤트나 경기가 벌어질 경우 주변에 들어서는 고층 주거 빌딩 및 기존 주거지역의 소음을 저감하기 위한 일차적 목적과 기존의 방수층이 노출된 지붕의 미관상(fig.01)의 이차적인 목적으로 다른 한 겹의 지붕 층을 추가하는 프로젝트였습니다.

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.
