  • Use of recycled aggregates in portland cement concrete (PCC) construction can offer benefits associated with both economy and sustainability. Testing performed to date indicates that recycled brick masonry aggregate (RBMA) can be used as a 100% replacement for conventional coarse aggregate in concrete that exhibits acceptable mechanical properties for use in structural and pavement elements, including satisfactory performance in some durability tests. Recycled brick masonry aggregate concrete (RBMAC) is currently not used in any type of construction in the United States. However, use of RBMAC could become a viable construction strategy as sustainable building practices become the norm. This paper explores the feasibility of use of RBMAC in several types of sustainable construction initiatives, based upon the findings of previous work with RBMAC that incorporates RBMA produced from construction and demolition waste from a case study site. A summary of material properties of RBMAC that will be useful to construction professionals are presented, along with a discussion of advantages and impediments to use. Several quality assurance and quality control techniques that could be incorporated into specifications are identified.

  • 국내외적으로 환경에 대한 관심과 규제가 강화되고 있는 가운데 건설산업 차원에서도 이에 대응하기 위해 친환경적인 건축 생산시스템을 구축할 필요성이 있다. 친환경적인 건축생산시스템의 일환으로 건설시공단계에서 발생하는 폐기물을 최소화하고 재활용률을 최대화할 수 있다면 친환경적인 건설생산시스템 구축에 기여할 수 있을 뿐만 아니라 경제적인 효과도 얻을 수 있을 것이다. 본 연구는 이러한 효과적인 폐기물 관리시스템 구축을 위한 선행 작업으로써 20층 이상 고층 공동주택단지에서 발생하는 폐기물의 발생시점부터 처리시점까지의 폐기물 발생패턴을 파악하고, 이를 기반으로 시공단계에서 건설폐기물 발생을 유발하는 주요 요인을 도출하였다. 사례조사를 통해 폐기물 발생패턴으로서 폐기물 종류, 발생량, 발생위치, 관리주체, 발생원인, 재활용폐기물, 집적형태, 반출방식을 조사하였고, 이들 항목 중 폐기물 발생에 가장 큰 영향을 미치는 주요폐기물 발생 유발요인을 제시하였다.

  • While it Is well-known that Total duality Management (TQM) can generate and sustain competitive advantage, its process and components have not been clearly identified for the construction industry. This paper aims first to enhance the understanding of TQM Content and Process. Then, drawing various seminal works on TQM and an application of market-based and resource-based theory, a consolidated model identifying the relationship among TQM principles and gaining a sustainable competitive advantage is proposed. Finally, the influence of TQM on sustainable competitive advantage of construction organizations is discussed, thereby interpreting the proposed model. Recognition of TQM's influence will be a starting point, enabling the construction industry to sustain their competitive advantage in the highly competitive global construction market.

  • With the increasing movement towards sustainable construct on, environmental rating systems (ERSs) came into use in the Middle Eastern (ME) region as similar to many other regions. ERSs were first developed to assess buildings and many ERSs have tended related ERSs. Despite the vast infrastructure development in the ME region and in the United Arab Emirates in particular, there is no understand the regional-specific requirements to attain sustainable construction and infrastructure. Tis research addresses these pags and study the theoretical underpinnings of sustainable infrastructure in the region, to propose a regional-specific, infrastructure-related ERS. This paper examines the underpinning factors of sustainable infrastructure in the UAE through a literature review in order to provide insights to determine criteria and subcriteria for the ERS.

  • Limited resources for construction material in the Mae-Hae region, a remote Northern Thailand, acted as an impetus to introduce a new way for constructing their dwellings. The new construction material brought new construction methodology, namely, using earth and bamboo which are indigenous materials, readily available for them to use. Using indigenous material at Mae-Hae region was most ecological and logical method for establishing sustainable dwellings both in terms of monetary and ecological reasons. Prior to the construction at Mae-Hae, Thailand, series of experimental tests on the strength of rammed earth were performed off site at our university and also brought soil samples from the actual job site at Mae-Hae for detailed soil analysis. Through the tests, integrity of the earth and characteristics of the soil were established to build a small senior citizen center as an example. This appropriate technology is expected to contribute to the sustainable construction at Mae-Hae.

  • Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

  • The aim of this study is to compare efficiency and Total Factor Productivity(TFP) between Korean and Japanese construction firms in Korea and Japan over the period of 2005-2011. The results of this study are as follows. Efficiency scores of Korean construction firms are 0.797, and Japanese construction firms are 0.921. Second, annual total factor productivity growth of Korean construction firms is 0.5% and technical progress do much for TFP decrease. However Japanese construction firms marked annual increasing of 2.5% of TFP. Third, technical progress contributed in TFP increase of construction firms in Korea. Korean construction firms, however, relatively lagged behind Japanese construction firms in technical progress. Therefore, Korean construction firms need strategies to achieve technical advances including adopting new technology or process innovation to maintain competitiveness, survive, and develop in the future competition with Japan.

  • This is a study about public-regeneration-architecture design of the 3rd world damaged by the development of capital society of the 20th century and from the perspective of economically poor, anti-capitalist development from non-profit design organization. Active among such non-profit design organizations, the sustainable design characteristics of public-regeneration-architecture of the Architecture for Humanity will be discussed. I help it so as a continuous possibility design to have been given to public-regeneration-architecture of the Architecture for Humanity is small, and I establish a construction space at a few costs to people in a situation to be environmentally interior economic, to be cultural, and I am large, and to be able to generate profitable construction by environment at activation of a local community and worldwide dimensions. I look through a sustainable design way of this study classifies it to cultural sustainability that ecology-cultural approach in the environmental sustainability result ecology - central approach, and how I was applied to materials of construction, color, a pattern, a construction method, space configuration etc. There is the meaning to try to analyze a characteristic of a sustainable design to have appeared to public-regeneration-architecture of the Architecture for Humanity which I make a symbiosis, and you can live on it how in the present cities that city poor floor will add to.
