Abstract

The biggest reason to prefer the remodeling is a relatively short period of time (5~6 years) compared to the reconstruction work that takes 8~9 years. In addition, from the perspective that the period of temporary residence is usually 24 months, the necessity of shortening is greater. Also, since the remodeling construction period is approximately 28~35 months on average, the strategies and efforts are needed to make up for the shortening the remodeling construction period. For these reasons, this paper is to develop an estimating model for normal project duration of apartment remodeling project. This model is reflected in the remodeling properties thorugh difference analysis of the new apartment construction project. Demolition works, reinforcement works, extension works are different, so this paper newly defines these construction work's duration in normal project duraion of remodeling. Case study and experts interviews are used to validate normal project duration. This model can be used to calculate rough construction period each alternatives, and will help a strategic decision making among the stakeholders.

리모델링을 선호하는 가장 큰 이유는 조합 구성 후 8~9년이 소요되는 재건축에 비해 상대적으로 짧은 사업기간(5~6년)에 있다고 할 수 있다. 그 외에도 입주민의 이주 시 임시거주를 위한 전세기간이 통상 24개월이라는 점을 감안할 때 공기단축의 필요성은 더욱 커진다. 또한 기존 증축형 리모델링공사의 기간이 평균적으로 28~35개월로 예측되기 때문에 전세 24개월이라는 공사기간을 만회하기 위한 전략과 노력이 필요하다. 이에 본 연구는 리모델링공사의 사업기간을 개략적으로 판단할 수 있는 리모델링 표준공기 산정모델을 개발하였다. 신축공사 표준공기를 토대로 리모델링공사와의 차이점 분석을 통해 리모델링 특성에 맞는 표준공기(안)을 개발하였다. 리모델링공사에서 새롭게 정의해야 할 표준공기 기준은 철거공사에 따른 공기변화, 보강공사에 따른 공기변화, 증축공사에 따른 공기변화로 크게 3공종으로 구분된다. 작성된 표준공기(안)에 대하여 사례연구와 전문가 인터뷰를 통해 적정성에 대해 검증하였다. 본 논문에서 개발한 리모델링공사 표준공기는 설계 대안별로 개략공기를 산출할 수 있는 기준이 될 것이며 리모델링 사업주체들간 전략적 의사결정에 도움이 될 수 있을 것이다.
