Abstract

Deconstruction of the building must be applied firstly in order to improve recycling and reuse of construction wastes. In this study have done a case study for deconstruction of an apartment. All construction waste(CW) which will be generated during deconstruction was examined in each part of the building. Because drawing did not exist in most of the old building, we drew up floor plans of buildings. After analyzing these drawings, estimated quantities of CW. It was measured working time of labor and equipments for deconstruction and general demolition on each building of the apartment. In addition, it was proposed in the volume and weight per unit after analyzing detailed measurement of CW which was generated in the process of deconstruction and traditional demolition. It suggested recovery rate at a site, volume and weight conversion factors, and waste basic unit per area that based on the results of comparative analysis on the amount of CW which is calculated from drawing and generated at a site. These factors will be used fundamental materials for estimating quantities and treatment cost of CW, and scheduling of works.

건설폐기물의 재활용과 재사용 비율을 높이기 위해서는 건축물의 분별해체 공법이 적용되어야 한다. 본 연구에서는 공동주택을 대상으로 시험시공을 실시하였다. 먼저 해체 과정에서 발생할 수 있는 모든 건설페기물을 건물의 각 부위별로 조사하였다. 해체대상 건물의 도면을 작성하고 이 도면을 분석하여 각 건설페기물의 발생량을 예측하였다. 공동주택의 한 빌딩씩 분별해체와 일반해체과정을 실시하면서 이 과정에 투입되는 인력 및 장비의 소요시간을 측정하고, 또한 각 해체과정에서 발생된 폐기물을 정밀 계측하여 이것의 체적, 단위중량 등을 제시하였다. 이러한 자료의 분석을 통해 도면분석 결과와 현장에서 발생된 건설페기물의 양을 비교분석하여 현장 회수율, 체적 및 중량 환산계수, 폐기물 원단위를 제안하였다. 이러한 계수는 건설페기물의 발생량 예측과 운반비 산정, 작업 공정계획 수립 등을 위한 기초적 자료로서 활용될 수 있을 것이다.
