In construction, stakeholders of extended project team play a key role in the overall project performance. Successful integration of stakeholders demands for good management practices at strategic, operational and project levels. Targets and measures to improve the stakeholder performance encourage the creativity and willingness of stakeholders of extended project team to develop the better ways to achieve the project objectives. This paper presents a generic descriptive method, showing how stakeholder's ability and influence impacts on project performance in the construction sector. The findings of a series of interviews with key informants are presented and the following main conclusion is drawn: improving project performance through stakeholder's contribution and measuring their performance can strengthen the project performance. This innovative approach which redefines the process of improving the project performance in construction projects will be of interest to those who intend to manage the projects in practice as well as to those who interested in advancing theory.

This study aims to systematically identify direct and indirect factors that influence labor productivity and to build a model that mathematically quantifies them so as to efficiently manage and increase labor productivity in the construction work. This study was performed based on the productivity model for workers in reinforced concrete construction projects, because it aims to establish a general construction labor productivity model that reflects many factors that influence labor productivity. Using statistical analysis, we found that the components that significantly influence productivity were the worker component, the work characteristic component, the work technique component, the work management component, the equipment & materials component, and the work guide component, while the work delay components did not significantly influence productivity. In addition, a priority analysis was performed based on the components that showed statistically significant effects. The results of the analysis indicated that the influence of work management component and the work technique component is more than that of the worker component and the work characteristic component. The construction labor productivity model that was formulated in this study could be used for the determining the standard productivity during the initial planning stage, so the best strategy for increasing labor productivity could be formulated.

Because of the development of advanced construction technology, the inner environments of building become more and more complicated, which may result in many problems. The administer may forget where they put up the certain picture, and search for it all over the building, or they underestimate the number of the visitors, and find the situation is out of control, while the pedestrian may get lost, and after making their efforts, they found they turned back to the origin point again. So it is very necessary to establish an indoor spatial database. On one hand, it is able to assist administrator to manage the property and human flow inside the building, on the other hand it could help the pedestrian find the way easily especially when they are not familiar with the building or there is an emergency. This paper focused on how to create the indoor spatial database including both static database and moving objects database. The static database is built on the basis of 3D building models, and the moving objects database gets information from many kinds of cameras and sensors installed in the building. And at the same time the paper discussed the practical use of indoor spatial database mainly in three aspects including consistency management, building restructure, and pedestrian navigation.

The continuing trend of built environment set forth by the rise of modernization and industrialization has led every country in achieving their respective economic development. Along side this trend is an issue that needs to be addressed - the environmental impacts of the built industry. Construction and maintenance of buildings are said to consume 40% of the world's energy, 65% of electricity, and 40% of raw materials, creating drastic pollutants harmful not only to the environment but also to human. Figures have been released and analyzed proving the contributions of built environment with environmental depreciation. Said figures earned concerns not just from different private and non-profit organizations but also the governments of every country, thus, steps towards sustainable development are being implemented. As a response, the "green" was added in the built environment. Later on, the now emerging concept of "National Green Building Code" found its role in the policy of various states in protecting the people in accord with the nature. This paper appreciates the initiatives of various countries and non-profit organizations in their drive to pursue sustainable green built environment in general, and specifically proposes an establishment of an "incentives grant framework" as an additional legislative policy to be included in the draft of the National Green Building Code of the Philippines.

An R&D project, 'Carbon Neutral Road Technologies Development', sponsored by the Korean Ministry of Land, Infrastructure, and Transport was performed and sustainable development is being discussed in relation to global climate change. A draft of the green highway certification system, the green highway design and construction technologies for making low carbon eco-friendly roads, and Green Highway Technology Investment Evaluation System (GTIES) for estimating and managing carbon emissions from roads have been developed from the results of the R&D project. A scheme for expanding the application of these technologies and building sustainable road systems by considering the concept of sustainability was proposed in this research.

This study is to concern about the effort of architectural practice to realize the sustainable architecture. It is necessary to know about the integrated design method which combines the passive design method with the active design method from the initial design phase. One case study is followed to explain the method. Integrated design starts from defining the project and goal setting, site evaluation, design concept, design optimization, documents and specifications, bidding and construction and post occupancy evaluation followed respectively. In order to construct the sustainable design, sophisticated understanding about nature and its' principle is important and adaptable application of nature and climate depending on location is followed. In conclusion, architects and specialists of sustainable design should make an effort more study.

This Study is about the check-List composition for 'Low carbon green growth' of Long-life housing. That utilization for required the check-list composition at Sustainable building strategies and Design methods. That for long life housing, sustainable building strategies part of building construction and interior, the proper foundation for legislative system, maintenance methods with in building life cycle, sustainable and green architecture capability realization prepare for connection plan with 'Low carbon-green growth'. Extracting from elements of Architectural planing answer to basic concept of Low carbon-green growth and aimed at Low carbon scheme for energy saving, green growth scheme for environmental conservation as to each application purpose reconstitute by classify Check-list category about elements of Architectural planing. Through this architectural research deduce elements of architectural planing that can be research utilization with in Check-list composition.

Since the apartment was built by Korea National Housing Cooperation in 1961, the amount of its supply has been increased greatly, especially from the late 70's. Recently there are many ongoing studies regarding sustainable construction apartment in Korea, one of the research is developing sustainable apartment that has longer life cycle. Also according as life's quality of residents is upgrading, complain for impact noise and plumbing system noise from upstair or downstair are increasing more and more. To solve this complains, government established impact noise standard as lightweight impact noise of 58dB, heavyweight impact noise of 50dB and presented standard floor system or recognition floor system to satisfy this impact noise standard. So in this study, the aim is to develop dry ondol access floor system for sustainable apartment which have pleasant and quiet life environment.
