Abstract

The research efforts to modernize Hanok (Korean traditional housing) have been performed to improve the quality and cost-effectiveness through application of modern building methods and materials, and to disseminate it in various forms of sizes and facilities. In this study, in order to identify the variations of modernized Hanok, data from seven test-bed projects are analyzed based on the building work-section, element, method, and material. The data were standardized and managed through the modernized Hanok classification system (Hanclass) to facilitate systematic comparisons of the test-bed projects by the variation of building method and it's cost impact. Identified factors of the variation in terms of building methods were then itemized and quantified in terms of building cost. Findings of this study indicate that the timber structure is the most critical area for future variation for improving the quality and cost-effectiveness. The results of this study will be also used to systemize the Hanok database for further studies.

한국 고유의 목조건축형태인 한옥을 현대 공법 및 재료 등의 기술의 적용을 통해 품질과 시공성을 향상시키고, 다양한 규모와 시설을 포괄한 신한옥의 형태로 보급 확산하려는 노력이 계속되어 왔다. 본 연구는 신한옥 표준분류체계(Hanclass) 적용을 통해 구축된, 일곱 개의 실증구축사업 사업비 정보를 분석하여 신한옥 공법변화의 추세와 함께 이에 따른 공사비 변화를 고찰하였다. 우선, 일곱 개 실증구축사례의 공법 특징을 분석하고, 이를 공종분류, 재료분류, 공법분류, 부위분류를 분석의 기준으로 설정하여 공사비에 끼치는 영향을 분석하였다. 또한 사례 프로젝트들에서의 공법 변화 주요 영향요인들을 항목화하고 연계된 비용변화를 정량화함으로써 향후 지속적인 공법과 비용간의 관계를 관찰하기 위한 기본 구조를 작성하였다. 본 연구의 결과는 지속적으로 개발되고 있는 신한옥의 신공법의 추세를 체계적으로 파악하고 또한 발전방향의 가이드를 할 것으로 기대한다.
