Issues in the construction industry of Cambodia in ASEAN Economic Community (AEC) is the main priority to be identified before identifying causing factors in order to find out recommendations, to improve this sector, and to survive in this community. Two major issues were identified from the literature review and the investigation, namely i) Long-term vision and its policy, and ii) practice culture. The total sample collected from concerned government officers and engineers in Cambodia were 463. Factor analysis was then conducted to find out the issues, and as the results, there are five issues in two main groups: (i) the Organization's vision and its skill, which consist of a vision of the organization, knowledge and skill, and less investmen in the construction sector; (ii) Knowledge and motivation towards the AEC, which consist of knowledge about the AEC, and level to promote organization for the AEC.

Construction industry is one of the most significant sector in national economic, but the portion of construction has been falling regularly with the regional development. In spite of decrease in economic portion, role of construction industry does not changed irrespective of development, as the foundation of development. To distinguish each state of the maturity, countries are grouped on GDP per capita, than compared with variance of GVA in construction and GFCF per GDP as level of construction industry. GVAc% and GFCF% shows corn-shaped plotting in increase of GDP per capita, and each value converge to around 20% and 5% as GDP per capita increase. The definition of maturity is consist of 4 stages; pre-developing, ascending, stabilization, and maturement. Maturity of construction industry is a term of broad sense of construction industry that is easily to figure current state of regional construction and shows what normal condition of construction is in regional economy.

Recently, major public owner and general contractors in Korea are actively preparing and improving BIM manuals and guidelines to effectively apply BIM technology in construction projects. These guideline has a purpose to define the scope of the applying BIM technology to each construction phase and to explain the minimum technology guidance required for the initial stage. In situations where BIM data are to be submitted within a limited time and cost at the design stage, a BIM data preparing process should be carried out in advance to meet the BIM interoperability between the pre and post of construction precess. In this research, we propose the scope of the BIM guidelines to meet and to be considered for the BIM based review of constructability and economic evaluation of Apartment.

The construction industry's lack of experience and expertise makes it difficult for projects to realize the full benefits of implementing modular construction. Such project performance-hindering elements are often labeled as modular challenges. The added requirement for the transportation of the finished volumetric module is one aspect of the 'module transportation logistics,' the under-researched modular challenge that can prevent projects from incurring maximum cost and productivity benefits. The typical module transportation phases include lifting, transporting, and offloading. From conducting a literature review, this paper aims to investigate the equipment commonly adopted to lift and offload the module and validate its economic efficiency by comparing it with the alternative lifting/offloading equipment used in the two case projects. The results showed that hydraulic jacks are an economic alternative to the crane for lifting/offloading the module. The increase in single-module projects with smaller budgets made crane usage economically undesirable, and this study suggested a viable option for a more economical alternative.

건설공사 발주자에게 건설현장 근로자에 대한 안전보건관리 책무를 부여하는 안전보건대장 제도가 「산업안전보건법」 전부개정에 포함되어 도입되었다. 안전보건대장 제도에 대한 낮은 인식과 이행률로 발생되는 제도의 실효성 문제를 해결하기 위해서는 경제성 측면에서 제도의 효과성을 설명할 필요가 있으므로 본 연구에서는 안전보건대장 도입 당시 논의되었던 자료를 근거로 비용편익분석을 활용하여 안전보건제도 이행의 경제적 효과를 분석하였다. 안전보건대장 제도 이행에 있어 추가적인 비용이 발생하는 것은 설계안전보건대장의 작성 및 관리로 분석되었다. 작성비용과 산업재해 감소로 발생되는 직·간접적 편익을 비교한 결과 편익이 비용보다 높게 평가되었으므로 안전보건대장 제도는 건설공사 재해 감소와 경제적 효과를 발생시키는 것으로 판단된다.

An Economic Sentiment Indicator(ESI) is a composite indicator of business survey indices(BSI) and consumer survey indices(CSI). The ESI designed to reflect economic agents' (this includes producers and consumers) overall perceptions of economic activity in a one-dimensional index. The European Commission has published an ESI since 1985. This paper demonstrates the construction of an ESI for the Korean economy. The BSI and CSI components (having a high correlation and a leading feature with respect to GDP) are selected to construct the ESI and they are aggregated using a weighted average and then scaled to have a long-term average of 100 and a standard deviation of 10. Thus values greater than 100 indicate an above-average economic sentiment and vice versa. The newly constructed Korean ESI that extends to January 2003 shows a good tracking performance of GDP and adequately reflects the overall perception of economic activity.

우리나라는 1989년 기술개발자의 개발의욕을 고취시킴으로써 국내 건설기술의 발전을 도모하고, 국가경쟁력 등을 제고하기 위하여 건설신기술 지정제도를 도입하였다. 국내 건설신기술제도가 1989년 최초 도입되어 2009년 12월 31일까지 총 596건의 건설기술이 신기술로 지정되어 건설현장에 총 3만여회 이상 활용되는 등 양적 성과를 거두었고, 국내 건설산업에 직 간접적인 영향을 미치고 있으나, 건설신기술제도의 도입 효과에 대한 체계적인 분석은 이루어지지 않고 있다. 이에 건설신기술제도 도입 이후 건설현장에 활용되었던 양적 성과 외에 건설산업에 직 간접적으로 영향을 미친 경제적 파급효과를 정량적으로 분석함으로써 동 제도의 운영에 따른 당위성을 확보하고 우수성을 검증하여 동 제도가 향후 지속적으로 발전할 수 있는 기틀을 마련할 필요가 있다. 본 연구는 건설신기술 사용으로 인한 공사비절감액, 공사비절감으로 인한 타 산업 비용절감효과, 취업유발효과, 부가가치 유발효과, 수입대체효과 등 건설신기술의 경제적 파급효과를 정량적으로 분석하였다. 이러한 연구결과는 건설신기술의 경제성과 우수성을 널리 홍보하고, 활용촉진을 도모하는데 활용할 수 있을 것이다.

In this study, the CO₂ emission and economic efficiency of high-rise apartment houses were evaluated, and were analyzed as a way to establish database on the evaluation of environment-friendliness of high-rise buildings. To that end, standard of buildings to be evaluated were proposed through analysis of the designing guideline for high-rise apartment houses proposed by Seoul city, and CO₂ emission of the subject buildings were evaluated based on the characteristics of materials admitted into each building and the amounts of energy consumed during lifecycle period. In addition, the initial costs in construction stage and annual costs in operation stage were set as analysis parameters, and along with calculation of direct cost by the consumption of construction materials and energy, the costs of CO₂ emission were evaluated and analyzed. As a result, the CO₂ emission and economic efficiencies of high-rise apartment houses by construction stage and operation stage could be analyzed quantitatively.

In China, the Reform-Open policy was executed in 1978. During the following 30 years, the economic regime in China had been changed to a socialist market economy from a socialist planned economy, and the construction industry in China has been achieved high economic growth. However, as the construction project increasing, a lot of problems which affect the construction expense payment occur. And it is a fact that the construction expense payment disputes have become a serious problem now. Therefore, it is necessary to discuss the problem of Chinese construction expense payment. In this paper, we would like to clarify the difference of the legislation of construction expense payment between China and Taiwan Region.

This paper deals with the after-tax economic feasibility analysis of the hydrogen fueling station considering dynamic utilization. We selected an off-site hydrogen station in which the hydrogen is supplied by a central by-product hydrogen plant as a case study. Also, we made some sensitivity analysis by changing input factors such as the discount rate, the hydrogen station construction cost, the hydrogen demand and the hydrogen sale price. As a result, the hydrogen station will not be economical in 2020 due to the relatively high price of the hydrogen station construction cost and the low price of hydrogen sale price. In order to realize the economic feasibility of the hydrogen station in the early stage of the hydrogen economy, the subsidies on the annual operating cost as well as the construction cost are needed.
