Abstract

The purpose of this study is to develope an assessment method for parking lot remodeling alternative by adopting the asset management technique. In order to identify the Level of Service(LOS) and the Evaluation Measurement(EM), literatures was implemented which documented the consideration of parking lot plan, needs of the apartments' tenant, and various design standards. In addition, the authors conducted a three-time delphi survey for the identified 5 LOS and 19 EM to evaluate suitability and necessity of them and to collect additional opinion of experts. The LOS of parking lot were categorized into 5 areas such as Environmental effect and Convenience, Accessibility and so on. The 19 EM were determined to estimate the LOS quantitatively. The researchers analyzed the degree of importance of LOS and EM by using the Analytic Hierarchy Process (AHP) method. But construction cost was excepted from the analysis, because it is used as an independent variable in alternative assessment. In conclusion, the authors proposed the estimation criteria for EM, and the method and process for alternative assessment be performed to benefit-cost analysis using the LOS variation and construction cost. The assessment method for parking lot remodeling alternative was demonstrated effective to assess the parking lot remodeling alternative by case-study. This study has a academic significance by adopting the asset management techniques in the area of the parking lot remodeling. And the assessment method is expected to help deciding a reasonable remodeling alternative of parking lot, as it ensures the diversity for remodeling of the parking lot and reflects the needs of the occupant.

이 연구에서는 주차장 설계의 다양성을 확보하고 입주자의 요구사항을 효과적으로 반영하기 위하여 자산관리 기법을 적용한 주차장 리모델링 대안 평가기법을 개발하였다. 문헌조사와 델파이 기법을 활용하여 주차장의 조경성, 편의성, 접근성, 경제성, 안전성 등 5개 LOS와 19개 평가항목을 제시하였다. 19개 평가항목 중 B/C분석에 독립적으로 사용되는 공사비용을 제외한 18개 평가항목을 대상으로 AHP기법을 활용하여 가중치를 산정하였으며, 평가항목의 점수 산정기준을 정립하였다. 대안의 평가절차 및 방법은 공공건축물의 자산관리 프레임워크를 적용하였으며, 원안과 대안의 LOS 변화량과 공사비용을 활용한 B/C분석을 통해 최적의 대안을 선정하도록 하였다. 주차장 리모델링 대안의 평가는 LOS의 변화량과 공사비용을 활용한 B/C분석을 실시하도록 하였다. 이 연구에서 제시한 평가기법은 사례연구를 통해 효과를 검증하였다. 주차장 리모델링 대안은 주차장의 확장범위와 필로티 주차장의 설치유무에 따라 총 세가지를 도출하였다. 사례분석 결과 LOS 점수는 지하주차장을 수직 수평 확대하여 2개층의 지하주차장을 확보하고 지상주차장을 조경공간으로 활용하는 대안이 최적안으로 선정되었고, 공사비용을 포함한 B/C분석 결과는 지하주차장 1개층을 수평확대하고 필로티 주차장을 신설하는 대안이 가장 합리적이고 경제적인 대안으로 나타났다. 이 연구에서 제안한 기법은 리모델링의 범위를 주차장으로 한정하여 아파트 리모델링과의 연계성을 검토하지 못하고, 계획단계의 평가항목만을 대상으로 사례적용을 실시하였다는 한계가 있다. 이 연구에서 제시한 주차장 리모델링 대안 평가기법이 실효성을 갖추기 위해서는 아파트의 리모델링을 포함하는 실시설계단계의 대안을 바탕으로 사례분석을 시행할 필요가 있다.
