Abstract

Currently, the multi-unit houses are the largest in the ratio of housing types, and the number of households in multi-unit houses is steadily increasing. As the multi-family housing project continues, the accuracy of estimates for decision-making and feasibility assessment are required in the early stages of the project. Therefore, this study selected the influential factors affecting the estimated estimate and showed the relative importance of each factor through weight analysis and suggested the method of calculating the estimated estimate to improve the accuracy. The calculation plan presented through this study will be used as a useful data for project feasibility review and is expected to make a great contribution in preventing the economic loss of the client.

현재 주택 유형별 비율은 공동주택이 가장 크며 공동주택의 가구 수는 꾸준히 증가하는 것으로 보아 공동주택의 건설사업은 여전히 지속되고 있는 것으로 나타났다. 이처럼 공동주택 건설사업이 지속됨에 따라 사업초기단계에서 의사결정과 사업성 평가에 대한 개산견적의 정확성이 요구되고 있다. 따라서 본 연구는 개산견적에 영향을 미치는 영향요인들을 선정하고 가중치 분석을 통해 요인별 상대적 중요도를 나타냈으며 정확성을 향상시키기 위해 개산견적의 산출방안을 제시하였다. 본 연구를 통해 제시된 산출방안은 프로젝트의 사업성 검토 시 유용한 자료로 활용될 것이며 발주자의 경제적 손실을 방지하는데 큰 기여를 할 것으로 기대된다.
