It became clear that Korean peninsula is not a safe region anymore from an earthquake disaster after Gyeongju and Pohang Earthquake in 2016-2017. Unfortunately, building industry in Korea has not been well prepared for an earthquake disaster and the following problems exist. First, the rate of buildings with proper seismic performance is relatively low. Second, the number of piloti buildings which are vulnerable to earthquake and fire disaster has increased recently. Third, the proportion of small-scale buildings excluded from the application of the building law for securing safety is too high. Fourth, widespread corruption and poor construction impede safety. Therefore, measures to prepare for earthquake disaster are as follows. First, methods of reinforcing building structures and reducing the seismic load acting on a building should be utilized in order to secure the insufficient seismic performance of buildings vulnerable to earthquakes. Second, whistleblowers should be encouraged and protected to prevent defective construction due to corruption. To this end, whistleblowers should be recognized as an effective means of protecting public interest not the traitor to the organization.

철근 콘크리트 건물은 반영구적이다. 하지만, 이런 사항은 시공방법에서 항상 언급되지는 않는다. 철근 콘크리트 건물의 내구성은 콘크리트 시공에 크게 의존한다. 따라서, 다음의 관점에서 철근 콘크리트 시공사 다음 사항을 언급할 수 있다. 1) 시멘트 수화작용과 콘크리트 내구성의 관계 2) 부실 공사 및 콘크리트 내구성 3) 콘크리트의 파울링(fouling) 메커니즘과 그 대책

It is not possible to define the earth's interior because of it complicity. However, it can be interpreted directly and/ or indirectly. Geophysics is the subject of this study. To study the possibility of construction supervision by geophysical method, geophysical prospecting was performed and studied at the SamYang pumping well area in Cheju Island, where, although underground dam was constructed, the saline water invade the pumping well area. This study focuses on the construction supervision by electrical measurements. Two electric resistivity survey lines are installed in the pumping well site, and at each line electric survey was conducted at ebb and flow tides. To increase the data quality SP (self-potential) survey was also performed. As a result the geophysical exploration methods explained the defect of construction well, and It shows that geophysical probe can be a useful tool for the construction supervision.

After IMF bailout crisis in Korea, project financing has been employed as a major funding vehicle for the housing development. In 2008, the recession of housing market due to the global financial crisis had an significant impact on the increasing insolvent site of PF based housing development project, resulting in serious impact to whole economy as a chain effect. In order to resolve this vicious circle of bankruptcy, the major construction companies were urged to take over the insolvent sites and invest to them for normal project exit, and finally play a critical role in normalization of market. Therefore, this study aims to define the core factors for decision making to invest to insolvent site and find out differences among constructors, developers, financial lenders. The results from AHP analysis, the profitability was the most important factor to constructors. Moreover, even though the location merit is little less, through competitive price, we can assure that stable profitability is most important factor to decide to invest in insolvent site. In conclusion, the price is cheap, is highly feasible, if the land secured, major construction company will participate in a PF business investment. These findings were verified by the investment case of major construction company.

건설부가 국회에 보고한 $\ulcorner$`93주요업무계획$\lrcorner$에 따르면 올해안에 건설업법개정을 추진 건설 기술개발 및 부실공사방지를 위해 현행 건설공사 표준품셈제도를 전면 재검토하고 부실시공 건설업체의 경우 면허취소와 함께 회사 대표자도 처벌하도록 제재를 강화하는 한편 특수건설업면허체제를 개편하고 하도급계열화를 확대해 중소규모 전문건설업의 육성기반을 다지기로 했다.

새해 3월부터는 부실벌점산정제도가 개선되어 건설업체와 기술자에 대한 부실벌점이 현행3년간 누계평균에서 2년간의 누계평균으로 바뀌어 산정되고, 4월부터는 연면적이 $495m^2$를 초과하는 건축물 및 다중이 이용하는 건축물의 시공과 대수선에 관한 건설공사는 반드시 건설업자에게 맡겨야 하는 내용을 포함해 건설교통부는 지난 12월 28일 새해부터 달라지는 제도를 발표하였다.

Although a range of machine excavation methods are in wide use, including casing, earth drill and reverse circulation drilling, deterioration in pile quality and faulty construction can be often found these days because of trouble in the construction field. For this study, research was conducted in the form of a survey of construction engineers working in the field in order to identify the types and the causes of trouble by focusing on all casing, earth drilling and reverse circulation drilling. By analyzing the causes of trouble, countermeasures could be presented. The data and the analysts presented in this study could be effectively used for minimizing trouble in future machine excavation work during construction.

Construction projects are getting more complex and larger-sized with a high economic growth rate and development of new construction technologies. In addition, interests and demands on standards of construction quality are further increasing. This trend requires more systematic and a higher level of construction quality management. While the government has strengthened the regulations for quality assurance, many quality problems have repeatedly occurred mainly due to lack of recognition for quality management and quality control systems. To address this issue, this paper aims to suggest quality management improvement scheme through analyzing 3,443 nonconforming items identified during inspection of 393 construction sites from March 2012 to October 2014. The quality management improvement scheme suggested in this research is expected to prevent quality problems and defects and thus improve construction performances.
