As the excavation depths during excavation works in urban sites are getting deeper and bigger, It is necessary to study for the improvements to solve the problems in the excavation processes. This research deals with the excavation method that can not only minimize the effect on the surrounding constructions, but also shorten the construction period of the excavation work. For this research, there have been an extensive literature review of the bibliographic data about Slurry Wall Method, which is recognized around the world, and the analysis of the major problems in the existing ineffective construction step. These efforts led to the technical improvements. Accordingly, a new construction method applied with the new technical factors has been suggested, and it was possible to compare Slurry Wall Method with the construction method and analyze them on the base of the examples using the suggested method. This new method decreased the excavation period by 15 days. It took only 33days to finish the excavation work, as compared to 48 days that can be seen on the pre-modification schedule. Furthermore, the suggested method in this research is safer, more economically feasible, and better for the environment than Slurry Wall Method. It will contribute to shortening the construction period of Slurry Wall Method in the end.

As online commerce increases, the construction of large logistics buildings worldwide is exploding. Most of these buildings have the characteristics of long span and heavy loaded and use precast concrete components, a pin joint structure, for rapid construction. However, due to construction safety and structural stability requirements, the pin joint structure has many limitations in terms of the erection of the PC member, which increases the time and cost. A structural frame connected with steel joints between precast concrete components, called a SMART frame, has been developed, which addresses these constraints and risks. However, the effect of the appllication of a SMART frame on the time aspect has not been analysed. The study is a time reduction effect analysis of a SMART frame for long span and heavy loaded logistics buildings. For this study, the authors select a case site erected using existing PC components, and compare the time reduction with the SMART frame erection simulations. Through this analysis, it was found that a time reduciton about 4 months, approximately 48% of the conventional PC installation period could be achieved. If the SMART frame is applied when carrying out future large-scale logistics building projects, it can be expected to have the effect of significantly shortening the construction period compared to the conventional method.

조금만 생각을 달리해도 그 결과는 매우 달라질 수 있다. 공법개선이란 남다른 것이 아니라 이러한 작은 아이디어가 모아진 것으로서 간편한 시공방법은 물론 인력절감, 공기단축 등으로 인해 공사비 절감을 도모하는 한편 품질향상을 꾀할 수 있어 업계는 신공법 개발에 부심하 노력을 기울이고 있다.

This study introduces the development of a precast concrete double-wall, applicable to basement construction in apartment buildings. Unlike traditional precast concrete double walls, the developed double-wall doesn't require specialized manufacturing equipment such as a lathe. The constructability of these advanced technologies was validated through a full-scale mock-up test using the precast concrete double wall. The test specimens were constructed to represent a structural wall with a thickness of 250mm. It was observed that the quality of the in-situ concrete, filled between two single panels of 110mm thickness each, was excellent. The construction efficiency of the developed double-wall system for basement construction in an apartment building was also examined. Expert interviews about installation times of precast concrete elements were conducted to evaluate the speed of the basement floor's installation. The results showed that installation of precast concrete elements, including the proposed double walls, could be completed within 20 to 29 days for a basement in an apartment building. This indicates a three-fold increase in construction efficiency compared to traditional methods relying on in-situ casting.

한탄강홍수조절댐의 형식은 기본설계(TK)시 지형 및 지질조건, 재료원 조건, 댐 안정성, 여수로설치조건, 친환경조건, 경제성 등을 종합적으로 고려하여 콘크리트중력심댐으로 결정하였으며, 콘크리트 중력심댐 축조를 위한 공법으로 재래식 타설공법과, Layer 타설공법을 가설비 규모, 시공성, 공기 등을 비교 검토하여 Layer 타설공법(R.C.D)을 채택하였다. Layer 타설공법은 일정 물량에 이상에 대해서는 일반 콘크리트 블록식 타설공법과 비교하여 경제성과 시공성 등이 양호하다고 할 수 있다. 본 연구에서는 현재 사업 진행중인 한탄강홍수조절댐을 통한 R.C.D공법과 일반 블록식 콘크리트 타설 방법을 비교 분석하고자 한다.
