The current construction industry mainly uses paper-based construction documents which are produced during the whole life cycle. The paper-based information hinders to reuse the construction information, due to the inefficiency to exchange and share the construction information between designers and constructors. To overcome these problems, construction CALS/EC (Continuous Acquisition and Life Cycle Support/Electronic Commerce) has been proposed by the government. It supports efficient reusing, sharing and exchanging the construction information using digitalized drawings and documentations. This study intends to show the future applying methodologies of using the standardized key technologies in the construction CALS/EC based on the case study of Korea and several countries.

This paper examines the relationship between the real estate policies of Korean government and the stock market of Korea. It is the purpose of this paper whether the government policies are effective or not when the Korean government release new real estate policies outlining higher taxes and more housing supply as part of its plan to suppress speculation. This paper studies the properties of daily stock returns of the construction sector in Korea securities market when the government announcements of the real estate policies are released. On the demand side, multiple home owners and those purchasing property for speculative purposes are expected to be hit the hardest If the government policies are effective. The empirical results of this paper show that most of the cumulative abnormal returns(CARs) are statistically significant from the year 2002 to the year 2006 except the year 2004.

As construction projects are complicated and large in scale, a collaboration between project participants is getting more emphasized over the last few years. The collaboration tools for participants are various. but traditionally drawings and specifications have played an important role. Especially, though storage form in drawings vary in entire construction lifecycle, drawings are still important as the core factor in latest information technology streams in regard to usefulness and reusability of information. As an attempt to standardize drawings in the public construction based on CALS/EC, this study analyzes user's requirements for drawings qualitatively, and looks into drawings standards in Korea, America and Japan, and each kind of ISO standard for drawings. And this study predicts future-oriented user's requirement for drawings based on Construction CALS/EC, and presents future-oriented direction of development applicable in domestic drawing standard in construction.

As buildings are changing variously from the side of use, efficiency and size, the construction qualities are more importantly recognized. Supervision system was enacted in the Residential Building Law in 1990 and responsibility supervision system in the Construction Engineering Management Law in 1994, respectively. However, recently revised supervision system in 2003 has some limitations: the present problems of appointing supervisor, disposing the supervisors, supervisor's works. Therefore, the aim of this study is to improve the present supervision system for mix-use residential building. By implementing the proposed revised supervision system, it will be able to expect quality improvement, confidence of the owner and the user, development of construction technology, and increase international competitiveness of supervision company.

Nowadays, as construction projects become bigger, the probability of construction accidents is higher than any other day. When construction accidents break out, we may suffer from the loss of life and property. For preventing these damages, there is lawed that some public constructions have to insure Contractor's all risks insurance policy (CAR), However, CAR is used to preventing the insured from the loss of construction accidents, it is debated that the premium rate of CAR is not fair to the insured (contractors) The objects of this thesis are as follows Firstly, the fairness of the premium rate of CAR is reviewed, and then the amount of risk of the insured evaluates and applies to the premium rate. Secondly, the development direction of components for evaluating the amount of risk of the insured is presented in the research. Lastly, how to use the team which assesses the risk of the insured and construction works is proposed for deciding reasonably the premium rate of CAR

In order to cope with the decrease of construction manpower caused by the aging population and to improve construction productivity, Japanese Ministry of Land, Infrastructure, Transport and Tourism has been promoting construction methodology using ICT (Information & Communication Technology) since 2016. The ministry has established and implemented new cost estimation standards, delivery systems, and government support policies to boost automated earthwork using ICT, and is expanding the types of automated construction methodology applied at the construction sites. To utilize ICT at construction sites in Korea, as in case of Japan, laws, systems, and policies should be readjusted first. By comparing the ICT-related systems and policies between Japan and Korea, this paper scrutinizes critical benchmarking factors. As a result, we have reached the conclusion that in order to promote ICT methodology at Korean construction sites, Korean government should establish ICT-related cost estimation standards, delivery systems, and economic support policies in advance.

Despite the efforts for enhancing the safety record, construction industry has been suffered from higher fatalities than other industries. The poor record of safety in construction industry means that there is a clear need for an effective countermeasure. As mentioned in previous studies, it is important to identify the type of activities or risks that are likely to cause accidents and to develop appropriate safety measures. Considering the large number of accident cases on the temporary installations including work platforms and work passages, the temporary installations should be managed first. To support it, this study aims to analyze falling accident cases on construction working platforms and passages which can lead to develop proper safety measures. Through the analysis of 1663 accident cases in the perspective of cost, progress, activity, and type of workers, this study identifies how the recent accidents occur and what is the cause of the accident occurrence. The identified causes of accident occurrence will help us to improve current construction safety.

Construction accident rates are reflected in the pre-qualification of public construction projects in order to prevent accidents and facilitate the safety management of construction companies. However, the construction industry is still experiencing an increase in accident rates. Hence, there is a need to strengthen existing safety evaluation systems and requirements in public construction tendering. The objective of this study was to acquire and provide basic data for benchmarking to select tenderers in domestic public construction projects. In Singapore and Japan, safety evaluation systems and requirements are applied based on various aspects in order to screen tenderers. These evaluation systems include safety regulations and institutional requirements, as well as safety performance and safety management plans of respective construction projects. This study recommends that korean public construction projects also apply similar safety evaluation systems which include comprehensive safety criteria in order to decrease accident rates in the industry.

현재 세계 각지에는 선박이 통항하는 항행수역에 해상교량이 건설되고 있다. 이와 동반하여 선박이 해상교량에 충돌하는 사고가 발생하고 있다. 우리나라에서도 2009년 인천 제2연육교의 완성과 더불어 선박이 통항하는 항행수역에 해상교량이 건설되는 경우가 많아지고 있다. 이러한 해역에 건설된 해상교량은 선박의 항행수역에 건설되기 때문에 타와 주기관의 고장 등으로 선박이 해상 교량에 충돌할 가능성이 있다. 이 연구에서는 이러한 충돌사고 예방을 위하여 외국 및 우리나라의 해상교량과 관련한 해양사고 발생 현황 및 원인에 대하여 조사하고자 한다.
