Indicators measuring performance and the level of informatization of construction companies have recently been developed. Construction companies' investment in informatization, however, is still relatively low compared to that of other companies in different industries, since it has been difficult in quantifying the effect of informatization on total performance. This study, therefore, conducted an industry survey using indicators provided by previous studies, and used them to calculate performance and informatization indices for construction companies. Finally, it suggested a quantitative analysis of the effect of informatization on these companies' performance.

Construction companies in Korea have shown interest in BIM (Building Information Modeling) even if late, adopted it, and applied it to several projects. But, it is hard to figure out the status of BIM implementation. Thus, this study is to figure out the status of BIM implementation in Korea by surveying major construction companies in Korea and comparing with similar surveys abroad. The survey result shows that only 11 companies in Korean construction industry adopted BIM. The clash check (73%) was mostly used among various BIM functions and other functions were used less than 30%. As of 2008, only 8 construction companies have used BIM in 27 projects and thus, Korean companies are in the BIM introduction period. Therefore, successful introduction of BIM is required by benchmarking the BIM introduction process of overseas construction industries

Industrial robotic arms are widely adopted in numerous industries for manufacturing automation under factory settings, which eliminates the limitations of manual labor and provides significant productivity and quality benefits. The U.S. modular construction industry, despite having similar controlled factory environments, still heavily relies on manual labor. Thus, this study investigates the U.S., Canada, and Europe-based leading modular construction companies and research labs implementing industrial robotic arms for manufacturing automation. The investigation mainly considered the current research scope, industry state, and constraints, as well as identifying the types and specifications of the robotic arms in use. First, the study investigated well-recognized modular building associations, the Modular Building Institute (MBI), and renowned architecture design magazine, Dezeen to gather industry updates. The authors discovered one university lab and a few companies that adopted Switzerland-based robotic arms, ABB. Researching ABB robotics led to the discovery of ABB's competitor, Germany-based KUKA robotic arms. Consequently, research extended to the companies and labs adopting KUKA models. In total, this study has identified seven modular companies and four research labs. All companies employed robotic arms and gantry robot combinations in a production-line-like system for partial automation, and some adopted design standardization for optimization. The common goal among the labs was to achieve greater flexibility and full automation with robotic arms. This study will help companies better implement robotic arm automation by providing recommendations from investigating its current industry status.

자금조달력이 부족한 건설기업은 수립된 건설정책에 적응하는데 상대적으로 많은 시간이 소요된다. 하지만, 금융기관이 담보력과 신용도가 낮은 건설기업에 금융상품을 제공하는 비율은 낮으며, 특히 중소건설기업이 금융상품을 제공받는 비율은 크게 낮다. 이 연구에서는 건설기업이 수립된 정부의 정책에 적응하는데 필요한 금융상품을 조사하고, 전문가 자문과 설문조사를 통해서 그 금융상품들에 대한 건설산업의 수요를 분석하였다. 또한, 조사된 금융상품들을 건설산업에 도입하기 위해서 개정이 필요한 법·제도를 조사하였다. 분석된 수요도와 개정이 필요한 법·제도 수를 기반으로, 건설산업에 금융상품을 도입할 경우의 우선순위를 분석하였으며, '회계사, 세무사, 변호사 등 전문가 컨설팅'의 우선순위가 가장 높은 것으로 나타났다. 향후 연구에서는 우선순위가 높은 금융상품을 건설산업에 도입하기 위한 금융상품의 개발기준과 개발방법에 대한 연구를 수행하고자 한다.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

Due to unique characteristics of small construction companies, safety management is comprised of complex problems (e.g., resources constraints, a lack of formalized management structures, low level of management safety commitment etc.). In order to understand causal interdependencies between safety factors at different system levels (regulation, organization, technical and individual), this paper aims to develop a system dynamics (SD) model of safety management in small construction companies. The purpose of the SD model is to better understand why small construction companies have low level of safety performance. A causal loop diagram (CLD) was developed based on literature, with an attempt to map causal relationships between variables. The CLD was then converted into stock and flow diagram for simulation. Various tests were conducted to build confidence in the model's ability to represent the reality. A number of policies were analyzed by changing the value of parameters. The value of a system dynamics approach to safety management in small construction companies is its ability to address joint effects of multiple safety risk factors on safety performance with a systems thinking perspective. By taking into account feedback loops and non-linear relationships, such a system dynamics model provides insights into the complex causes of relatively poor safety performance of small construction companies and improvement strategies.

본 논문에서는 건설경기가 규모별 건설업체 부실화에 미치는 영향을 벡터오차수정모형(VECM : Vector Error Correction Model)을 통해 분석하는 것을 목적으로 한다. 본 논문에서는 먼저 KMV(Kealhofer, McQuown and Vasicek) 모형을 기반으로 산출하는 예상부도확률을 건설업체 부실화를 나타내는 대리변수로 정의하였다. 본 논문에서는 규모별로 예상부도확률을 측정하기 위해서 건설업체 상장기업 중 30개 업체를 선정하여 규모별로 상위 15개와 하위 15개로 구분하였다. 건설경기 변화를 대리하는 변수로 주거용, 비주거용, 토목용 건설수주액을 활용하였다. 각 변수들의 시계열 데이터는 한국상장회사협의회의 TS2000과 통계청 자료를 통해 확보하였다. 분석기간은 2001년 2분기부터 2015년 4분기까지로 설정하였다. 먼저 규모별 건설업체의 예상부도확률을 산출한 결과, 일반적으로 알려진 바와 같이 대형 건설업체가 상대적으로 규모가 작은 건설업체보다 부실화 정도가 낮은 것으로 확인되었다. 하지만 벡터오차수정모형을 기반으로 한 충격반응분석 결과 대규모 건설업체가 경기 변동에 더욱 민감하게 반응하며, 특히 대규모 건설업체 경영상태 변화에 주거용 건설시장 변화가 주요 요인인 것을 확인할 수 있었다.

As domestic recession has had an adverse impact on many Korean companies in Korea, financial soundness has become a critical issues. It is essential to identify financial risk factors to prevent workout as well as to improve the financial condition of domestic construction companies. Therefore, this study derived important management indicators and the financial ratios that belong to each indicator through a comparative analysis between healthy companies and workout companies with financial statement. As a consequence, key financial ratios are derived into 3 of 25 ratios; Equity Ratio in stability indicator, Total Asset Turnover Ratio in activity indicator, and Labor Equipment Ratio in productivity indicator. So, Korean construction firms are required close monitoring these critical financial ratios indicating variation between construction companies which have opposing statuses in finance in order to keep sound financial condition and increase productivity.

Indian construction companies have only 0.05% market share in the 3-4 trillion dollar global construction business and only two Indian construction companies figure in the ENR "Top 225 Global Contractors 2006" list. Hence, while enormous scope for growth exists, international construction experience is limited. This study explores the risks as perceived by Indian companies venturing abroad since risks in international construction differ from home market risks. Literature survey identified a number of risk factors that were evaluated by the experts, highlighting fourteen important risk factors. Interpretive Structural Modelling (ISM) was used to develop a hierarchical model showing the relationships between the different risk factors, thus helping to focus on the key risks for effective risk management. The study shows that poor project management is a key risk forming the hub of the system, while political instability has maximum influence. The results of the study can be used by managers to visualise the risks in perspective and prioritise the mitigation effort.
