초록

공동주택에 대하여, 2000년 이후 건설한 대상 실적 중 25개 현장에 골조. 미장, 내장, 설비, 전기 통신, 기타의 공종별로 구분하여 월별 노무량의 투입실적의 자료를 수집하였다. 이를 100%기간으로 표준화 된 공기로 변환하여 공종별로 구분하여 노무량 비율로 환산하여 노무비율의 흐름을 분석한 결과 다음과 같이 결론을 도출하였다. (1) 노무비율의 크기는 골조공사 38.25%, 미장공사 5.10%, 내장공사 5.67%, 기계설비공사 9.10%, 전기 통신공사 8.76%, 기타공사 33.12%로 골조공사가 가장 크다. (2) 노무비율이 투입 되는 피크 시기는 52.5%월부터 62.5%월까지이고 3.6%의 노무비율이었다. (3). %월별로 골조공사가 가장 큰 시기는 35%월이고 이때 %월당 2.12% 투입 노무비율이었다. 골조공사가 마무리가 시작되는 65%월부터 80%월에 서로 다른 공종간의 상호 간섭이 가장 큰 시기였다. 본 연구의 결과는 공동주택 건설공사에서 공종별로 가장 큰 혼잡도가 높은 시기를 알려주고 있으며, 이 시기의 집중 공정관리 하는 것이 성공적인 프로젝트 수행에 필수적인 사항이 된다.

Apartment Housing 25 in the field of construction since 2000 collected by types of labor: reinforced concrete, plaster, internal, equipment, electrics communication, the other work. And the performance of labor input was collected in the amount of construction work performed on a monthly basis. After changing the construction period in the standardization work that is 100% of the construction period, the amount was converted into labor ratio by type. Analysis of the input flow rate and the amount of labor conclusions were as follows: (1) The size of the labor rate is reinforced concrete work (38.25%), plastering work (5.10%), internal work (5.67%), equipment work (9.10%), electrics communication (8.76%), the other works (33.12%) and the size of labor rate is the largest work in reinforced concrete work. (2) The peak of labor input ratio was from 52.5% month to 62.5% month. This was when the labor rate of 3.6%. (3) The period month of the largest labor ratio% is 35% month by reinforced concrete construction, and this time it was 2.12% per month labor rate, and reinforced concrete construction is finishing from 65% month to 80% month. This showed the greatest congestion of mutual interference between each works is being continue. The results of this study are the greatest congestion in apartment housing construction has informed the high period(%months), which is essential to a successful project.
