Abstract

Recently, interest in remodeling apartment houses has been increasing due to problems such as a lack of parking spaces for old apartment houses. However, no method was suggested to predict the construction period of the apartment remodeling project. Unlike general apartment new construction, apartment remodeling construction involves demolition or reinforcement work, so a realistic remodeling construction period calculation plan differentiated from the existing construction period should be proposed. Therefore, this study intends to present a model for deriving the construction period of the underground parking lot of the apartment remodeling construction. Each construction period was calculated based on 19 activities of underground parking lot remodeling work through review of previous studies and expert advice. Activity's workload data and productivity data were derived to calculate the construction period, and the number of inputs and equipment inputs by Activity were determined to correct the productivity data. The construction period of Activity was calculated using the derived data, and the criteria for calculating the overlapping period for each Activity were presented to enable realistic construction period and scheduled schedule. As a result of predicting the accuracy of the construction period through the verification of the case complex, it is expected that it will be possible to predict the approximate construction period of the underground parking lot of the apartment remodeling construction in the future.

최근 노후 공동주택의 주차면수 부족 등의 문제로 공동주택 리모델링에 대한 관심이 높아지고 있다. 하지만 공동주택 리모델링 사업의 공사기간을 예측하기 위한 방법은 제시되지 않았다. 공동주택 리모델링 공사는 일반적인 공동주택 신축공사와 달리 철거공사나 보강공사가 수반되기 때문에 기존 공사기간 산정방안과 차별화된 현실성있는 리모델링 공사기간 산정방안이 제시되어야 한다. 따라서 이 연구에서는 공동주택 리모델링 공사의 지하주차장 공사기간을 도출하기 위한 모델을 제시하고자 한다. 선행 연구 고찰 및 전문가 자문을 통해 지하주차장 리모델링 공사의 19가지의 액티비티를 기준으로 각각의 공사기간을 산정하였다. 공사기간 산정을 위해 액티비티의 작업량데이터와 생산성데이터를 도출하였고, 생산성데이터의 보정을 위해 액티비티별 투입인원 및 장비투입대수를 결정하였다. 도출된 데이터를 활용하여 액티비티의 공사기간을 산출하였고, 액티비티 별 중첩기간 산정기준을 제시해 현실적인 공사기간과 예정공정표 작성이 가능하도록 하였다. 사례단지 검증을 통해 공사기간 정확도 예측 결과 정확도는 90%이상 일치하는 것으로 나타나 향후 공동주택 리모델링 공사의 지하주차장 개략 공사기간 예측과 공정표 작성이 가능할 것으로 기대된다.
