Abstract

The Global's top five Design Firms selected from BauNetz a German architectural magazine in 2007 designed free form building design which was 25% of the overall design by 2006-2010. Free form building is a landmark of the city and the country so its social and economic impacts are very large. In case of Korea, free form buildings such as Tribowl in Incheon, KINTEX Exhibition hall 2 and Dongdaemun Design Plaza have increased. However, those the increase in design trends and, the needs due to the lack of free form building design and construction management experience, free form building projects can't be expected to profitability and have a number of problems after completion. Especially, there are many excessive quality problems and the rising cost due to design changes frequently and lack of experience and data. Thus an initial plan regardless of considering of free form building's characteristics can be a huge risk because of the difference with the plan and actual projects, yet there aren't free form building project's performance data and case studies related to productivity. In this study, through selection of low-construction productivity works and an analysis of the work process and productivity data, hope to propose an actual field productivity of free form building and the ways to improve productivity.

2007년 독일의 건축 잡지 바우넷에서 선정한 세계 5대 설계사들의 2006 ~ 2010년 설계한 전체 설계 중 25%가 비정형 건축물로, 비정형 건축물은 도시, 국가의 랜드마크로서 그 사회적, 경제적 파급효과가 매우 크다. 국내 또한 인천세계도시축전 기념관, 킨텍스 제2전시관, 동대문디자인 플라자 등 비정형 건축물이 증가하고 있다. 그러나 이러한 설계 트렌드 및 증가하고 있는 비정형 건축물의 수요에 반해 이를 충족할 만한 비정형 건축 프로젝트의 설계 및 시공 관리 경험 부족으로 인해 비정형 프로젝트는 수익성을 기대하기 어렵고, 완공 후에도 많은 문제들이 부각되고 있다. 특히 국내 인력의 비정형 프로젝트 수행 경험부족으로 인해 불확실한 공사비 예측, 설계 과다변경 등으로 인해 완공 후에도 품질 문제를 비롯한 공사비 상승 관련 문제들이 계속 발생하고 있으며, 이와 같은 비정형 건축물의 특성을 고려하지 못한 초기 계획은 프로젝트 수행 시 실제와 그 차이가 커 프로젝트 관리 리스크로 작용하지만 아직 비정형 건축물 프로젝트 관련 실적자료나 사례분석 자료 구축은 미비로 인해 어려움을 겪고 있는 실정이다. 따라서 본 연구에서는 비정형 건축물 공사 중 생산성이 낮은 공종을 선정하여 작업 프로세스 분석 및 실제 현장 생산성 자료 분석을 통해 실질적인 생산성 자료 구축 및 비정형 건축물 공사 생산성 향상 방안을 제시하고자 한다.
