Abstract

As logistics facilities have a high ceiling height, simple structure, and the need for a quick return on investment, it is usually essential to advance the construction schedule of such facilities. Accordingly, PC structures, which require less labor, cost and schedule, can be more competitive than RC structures. However, most construction companies in Korea are familiar with RC structure design, have negative perceptions regarding PC structures, and do not sufficiently adopt new construction techniques. The structure that this research features has 110 columns that are 14 m high and are built to the same specification, and applying an RC design to the structure will lead to issues related to constructibility, economic viability, project duration and safety. Therefore, this study intends to feature PC design as an alternative to the RC warehouse design, and perform a comparative analysis of the reduction in labor, cost and construction schedule to highlight benefits. The research outcomes herein will provide inputs to subsequent studies on new construction strategies to advance the construction schedule, improve quality and constructibility, enhance safety and save costs.

물류시설은 층고가 높고 구조가 단순하며, 투자회수를 위한 조속한 운영이 필요하기 때문에 공기단축이 절실한 특징이 있다. 이에 따라 인력 및 원가절감, 공기단축을 기대할 수 있는 PC공법의 사용은 RC조에 비해 경쟁력을 확보할 수 있다. 그러나 국내의 시공사들은 RC공법에 익숙해져 있어, PC공법에 대한 부정적 인식이 팽배하며, 새로운 공법적용에 대한 노력이 미흡한 문제점이 있다. 본 연구의 사례현장은 단위기둥의 높이가 14m로 동일한 규격의 장주(長柱)가 110본 소요되는 현장으로 RC공법을 이용할 경우 시공성, 경제성, 공사기간, 안전성등의 문제발생이 예상된다. 따라서 본 연구는 RC조로 계획된 물류창고 현장을 PC공법으로 시공하여 인력 및 원가절감, 공기단축효과를 비교분석하고, 개선효과를 제시하는데 목적을 두고 있다. 향후 본 연구의 결과물은 물류시설 시공 시공기단축, 품질 및 시공성 향상, 안전성향상, 원가절감효과를 가져올 신공법개발 연구의 기초자료로 사용될 것으로 사료된다.
