1997년 11월 IMF 영향에 따른 ○○건설사의 부도로 인해 1년동안 ('97. 11∼'98. 11) 공사가 중단된 채 방치되어 많은 문제점을 안고 공사를 재개하지 못하고 있는 현장이 전국에는 아직도 100여개 정도 산재해 있는 것으로 알고 있다. 이와 같은 현장의 공사재개를 위해서는 다음과 같은 문제점을 검토해야 한다. 첫째 기술적 문제점으로는 기초와 지하주차장 골조공사가 일부 시공중 중단되어 철근이 1년 동안 방치된 채 부식되어 있어 구조물 안전진단은 물론 부도에 따른 기 시공 협력업체들의 채무정리(22개사)에 대한 문제가 해결되지 많아 공사의 재개에 많은 어려움이 있으므로 충분한 사전검토가 필요하다. 둘째 외부적 문제점으로는 그동안 공사중단으로 인한 입주자들에 대한 신뢰확보 즉 조합 및 분양자들이 건설사의 부도로 인한 중도금 납입 거부상태는 물론 선납금, 연체이자 등의 경제적 피해 손실로 발주처에 대한 집단소송 진행 등에 따른 건설사 및 발주처에 대한 불신 해소를 어떻게 하느냐가 공사재개의 중요한 관건이었다.(중략)

The purpose of this paper is to analyze the additional construction cost of G-SEED certification for domestic office building reflecting the latest standard(G-SEED 2016-2), and to derive cost impact by category and level. Therefore, it is intended to provide quantitave cost data according to G-SEED certification at the planning phase of the project, estimate the additional construction cost per level according to G-SEED Certification of similar project to be carried out in the future, and encourage G-SEED certification by supporting the decision of the owners. Method: The Process and method of this study are summarized in five steps, 1) Review of previous research, 2) Selection of target project, 3) Scenario setting by level, 4) Additional construction cost for each evaluation category, 5) Extraction of additional construction cost ratio by level. Result: This paper analyzed the cost impact by deriving the additional construction cost of detailed category for level improvement according to the revised G-SEED certification(G-SEED 2016-2). In conclusion, an additional construction cost(ratio) of G-SEED projects to the reference building is drawn as good level; 157,426,241 KWN(+0.43%), very good level; 321,907,802 KWN(+0.88%), excellent level; 999,371,478 KWN(+2.74%), and outstanding level; 1,467,047,718 KWN(+4.02%).

Chinese construction companies take major roles gradually in the global construction market. Chinese construction companies performs well-organized project execution by the construction related professionals based on the domestic education and qualification system. The purpose of this study is to analysis the characteristics of professional qualifications for constructor and quantity surveyor in China. The result shows that qualification systems of constructor and quantity surveyor are well classified in detail and operated by government. Each qualifications require broad and defined knowledge structure together with practical experiences. The research result will open the further research of Chinese construction related qualifications in the ways of more specificity, expertise, and practicality.

In this study, surface performance evaluation was conducted according to the fiber and surface finishing technique of the exterior material using Ultra High Performance Concrete(UHPC), whitch is spotlighted as a highly durable exterior material. As a result of outdoor exposure, the initial performance of the UHPC Panel using organic fibers was maintained without being affected by the surface finishing technique. In the specimen using steel fiber, the surface performance was maintained when the water repellent treatment was performed in the plain specimen, but fiber corrosion occurred in the specimen to which the surface finishing technique was applied.

This research reviewed the status of binder removal depending on the heating temperature and duration by using the 3D sand mold as an electric heating method. In the case of the electric heating method, it was confirmed that a heating temperature of at least 800℃ or higher was required to remove the binder of the 3D sand mold, and the heating duration was confirmed to be about 10 minutes. Afterwards, it is considered necessary to further evaluate the additional binder removal method and the utilization of recycling silica in consideration of economic feasibility and productivity.
