건설엔지니어링 기업은 대표적인 지식기반산업으로서 무형자산의 평가 및 관리가 더욱 필요하다. 본 논문에서는 기업 특성을 고려하여 무형자산 분류체계를 작성하고, 설문과 인과지도구축을 통해 주요요소를 추출하여 건설엔지니어링 기업의 무형자산 측정을 위한 요소분류체계를 제시하였다. 기업가치 상승을 위한 무형자산 관리는 각 무형자산 세부요소 간 인과관계에 대한 이해가 뒷받침돼야 하므로, System Dynamics 분석을 통하여 인과관계를 파악하고 제시된 방법론을 검증하였다. 제시된 방법론을 통하여 건설 엔지니어링 기업의 특성이 고려된 무형자산을 인식하게 되어 건설엔지니어링 기업의 무형자산을 합리적으로 평가하는데 기여함으로써 건설엔지니어링 산업의 발전을 도모할 수 있을 것으로 기대된다.

More and more organizations in construction industry adopt knowledge management system (KMS) to facilitate process of creating, acquiring, capturing, sharing, and using knowledge so as to improve the competitiveness, productivity and efficiency of their organization. In spite of the tremendous efforts devoted to KMS, the return of investment on KMS is usually a black box to the investor due to the lack of a systematic framework for performance evaluation of the KMS. This paper aims at fulfilling such need. A conceptual performance evaluation framework is proposed based on Balanced Scorecard (BSC) method. Then a preliminary case study is conducted to assess the applicability of the proposed framework in an A/E consulting firm to evaluate the performance of KMS.

The growth-share matrix is a portfolio planning tool developed by the Boston Consulting Group (BCG) to assist competitive positioning in the international market including those in the construction industry. This matrix is helpful in balancing the firm's cash-flow, and it can suggest strategic directions for each business unit. However, its effectiveness and applicability have long been debated in the academic field due to the complex and unique industrial context of construction. To solve the dispute, this research clarifies the applicability of theories underlying the growth-share matrix to the construction industry. Empirical research based on actual financial data of Korean construction firms is adopted for the statistical analysis including one-way analysis of variance and correlation analysis. The results of this research show that empirical findings on the relationship between performance variables. In this context, this research can provide important insights on the concept of portfolio management in the construction industry.

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.

Prefabricated partially-encased composite (PEC) structural component is widely used in construction industry due to its superior structural performance and easy assembly characteristic. However, the solid web in traditional PEC components tends to split concrete into two halves, thus potentially reduces structural integrity and requires double concrete pouring. To overcome the above disadvantages, a new PEC beam with open-web π-shaped steel is proposed in this paper. Four open-web PEC beams with varying sectional height, flange thickness and web void rate were constructed and tested under flexural loads. During experimental tests, all beams exhibited typical flexural failure modes with strong moment capacities and excellent ductility. Owing to the unique construction form of web opening, steel-concrete bonding properties were enhanced and very small relative steel-concrete slips were observed. Experimental results also showed that the flexural capacity of such PEC beams increased with the increase of the sectional height and flange thickness, while was not affected by the web void rate. At last, a flexural capacity formula of the open-web PEC beam was proposed based on the whole section plastic rule. The formula results agreed well with experimental results.

엔지니어링 기업의 해외시장진출이 어려워지는 상황 속에서 ODA 사업은 해외진출의 돌파구가 될 수 있다. 그러나 다수의 해외 기업들이 한정된 사업을 두고 경쟁하기 때문에 사업 수주를 위해 다른 기업과 협업하여 입찰 경쟁력을 상승시켜야 한다. 기업의 경쟁력은 기업의 경험, 평판, 협업을 통한 네트워킹이 축적된 결과물이기 때문에 장기간에 걸쳐 어떤 협업전략을 취하느냐에 따라 낙찰 여부가 달라질 수 있다. 따라서 본 연구의 목적은 ODA 사업 낙찰에 유효한 협업 전략을 도출하는 것이다. 이를 위해 세계은행에서 제공하는 베트남 컨설팅 사업의 입 낙찰 정보를 수집하여 기업 간 협업을 나타내는 협업 네트워크를 구축하고 사회연결망분석을 수행하였다. 이후 로지스틱 회귀분석을 수행하여 공종별로 낙찰에 유효한 협업 전략을 제시하였다. 분석 결과 교통인프라 및 도시개발 사업은 다양화 전략이 수자원인프라 사업의 경우 집중 전략이 낙찰에 유리한 것으로 도출되었다. 본 연구에서 제시한 컨설팅 사업의 공종별 협업 전략은 향후 국내 엔지니어링 기업이 베트남 시장 진출 시 참고 자료로 활용될 수 있다.

Environmental issues have become gradually important around the globe, which has increased society needs for the environment-friendly construction. In an effort to realize the environmental protection and energy efficiency, the British BREEAM has been developed, which is followed by the USA LEED, Japanese CASBEE and other national certification systems based on their own conditions. In this end, the Republic of Korea has implemented its own certification system named GBCS(Green Building Certification System) in 2002, and now actively promoted the G-SEED(Green Standard for Energy and Environmental Design) after GBCS modifications and amendments. The purpose of this study is to identify possible problems to be encountered in the process of the G-SEED for office facilities and to provide relevant solutions. In this end, three office facilities have been selected, which had obtained the G-SEED. This study has analyzed reasons of change of assessment scores between the preliminary certification and the main certification phases, has identified problems through in-depth interviews with practicing professionals(design, construction, eco-friendly consulting firm) and then has reached a conclusion for improvements. This study will be possibly used as reference materials for improvements of the green building certification system, and further detailed studies on respective parts will be required for improvements.
