  • The standard production unit system is the most basic element in our country construction. However, this standard production unit system shows a large difference in the actual amount of labor input for works at the Apartment housing construction, Therefore, it may be a reasonable alternative to estimate the cost of construction by historical cost data, works will be calculated the cost of labor must determine the exact amount and It is necessary to determine the exact amount of labor input for the construction progress management. This study examines the results of comparing the standard production unit system and the actual amount of labor counting in apartment housing construction was completed in the metropolitan area since 2000, the following results were obtained. the actual amount of labor input are looked for 1.184person/1000 of masonary, $0.084persons/m^2$ of plaster, $0.039persons/m^2$ of Waterproofing, $0.059persons/m^2$ of tile at the Apartment housing construction. in the actual amount of labor counting Compared with standard production unit system, masonry ratio of 59.8%, plaster ratio of 41.3%, waterproofing ratio of 31.5%, tile ratio of 34.3% and The labor rate in the works was the lowest in the plaster. was relatively high in the masonary. Therefore, the amount of labor country apartment housing construction is preferably calculated on historical cost data. But it seems that the amount of labor necessary complement ongoing close enough to the actual standard production unit system a major variable in construction management.

  • 본 연구는 조적공사 중 반매(0.5B)쌓기 시멘트벽돌 시공시 개구부 상부에 시공되는 중량의 인방보용 콘크리트 구조물 대신 경량의 강재구조물을 안전하게 사용할 수 있도록 강재구조물이 개구부 상부 시멘트벽돌 하중을 견딜 수 있는지 실험을 통해 검증해 보기위한 것이다. 강재구조물이 시멘트벽돌을 쌓는데 방해가 되지 않도록 강재구조물 형상을 제안하였고 휨실험을 실시하여 구조형상을 검증하였다. 실험결과를 바탕으로 강재구조물에 치올림(camber)을 두어 시멘트벽돌 반매(0.5B)쌓기 실물 재하시험을 실시한 결과 시공성이 개선되고 공사 중 안전사고 방지에도 효과가 있는 것으로 확인되었다.
