Abstract

Due to the increase in the size of buildings and scale, the importance of construction engineering that reflects the constructability from the design stage of the project is increasing. Especially, engineering efforts related to facilities, equipment and construction methods for temporary work at the design stage can significantly contribute to improvement of constructability and project performance. The purpose of this study is to derive construction engineering tasks on temporary work at the design phase of the high-rise building projects. 27 preliminary tasks were firstly investigated through literature review and experts' group interview, and the necessity and importance analysis of each tasks were then performed based on questionnaire survey. Most of the tasks related to plans on structural framework and lifting equipment were analyzed as relatively more important ones. Lastly, 21 engineering tasks, which are classified into 5 factors, were proposed through factor analysis. The factors were determined as 1) structural framework, measurement and circulation, 2) lifting equipment and pumping, 3) space zoning, 4) water supply, 5) temporary facility, electric power supply and lighting. The results of this study can be used as basic data for establishing efficient work process of construction engineering on temporary work at the design phase.

건물의 고층화와 규모의 증가로 인해 프로젝트 설계단계에서의 시공성을 반영한 엔지니어링 기술의 중요성이 점점 커지고 있다. 특히, 설계단계에서의 가설작업을 위한 설비, 장비 및 공법과 관련된 엔지니어링 기술적용의 노력은 시공성 및 프로젝트 성과 향상에 크게 기여할 수 있다. 이에 본 연구에서는 고층 건축공사의 시공성 향상을 위하여 가설공사를 중심으로 설계단계에 요구되는 시공엔지니어링 업무를 도출하고자 하였다. 우선, 문헌고찰과 전문가 집단면접을 통해 27개의 예비 업무를 도출하였으며, 그 후 설문조사를 통하여 각 업무의 필요성 및 중요도를 분석하였다. 분석 결과, 골조공사 및 양중장비 계획과 관련된 대부분의 업무가 상대적으로 중요한 것으로 분석되었다. 마지막으로 요인분석을 통해 21개의 엔지니어링 업무를 선정하였으며, 이들 업무는 크게 1)골조공사 및 측량/동선계획, 2)양중 및 콘크리트 압송계획, 3)공간구획계획, 4)용수계획, 5)가설건물 및 전력/조명계획의 5개 요인으로 분류되었다. 본 연구의 결과는 설계단계에서 시공엔지니어링 업무를 효과적으로 반영할 수 있는 프로세스 수립을 위한 기초 자료로 활용될 수 있을 것이다.
