Abstract

This study analyzed the work characteristics of water meter replacement projects in Cheongju City using field surveys and replacement records. A total of 683 replacement cases were collected and evaluated to investigate the effects of meter diameter, connection type, and installation environment on replacement time. The results showed that replacement time increased with meter diameter and that flange-type meters required longer replacement times than union-type meters. In addition, work productivity varied according to installation environment, including apartment complexes, urban residential areas, and rural/commercial areas. The findings indicate that labor requirements should consider not only meter diameter but also connection type and auxiliary work such as strainer replacement. The results provide useful reference data for labor estimation and cost calculation in water meter replacement projects.

본 연구에서는 청주시 수도계량기 교체사업을 대상으로 현장조사 및 교체실적 자료를 활용하여 계량기 구경, 연결방식 및 작업환경에 따른 작업특성을 분석하였다. 총 683건의 교체자료를 분석한 결과, 계량기 구경이 증가할수록 교체시간이 증가하는 경향을 나타냈으며, 동일 구경에서도 플랜지형 계량기가 유니온형 계량기보다 더 긴 작업시간을 보였다. 또한 아파트, 도심지 및 교외지역 등 설치환경에 따라 교체시간의 차이가 발생하는 것으로 나타났다. 특히 플랜지형 계량기의 경우 스트레이너 교체 등 부대작업이 함께 수행되어 공수 증가에 영향을 미치는 것으로 분석되었다. 연구 결과는 수도계량기 교체사업의 적정 공수 산정 및 예정가격 산정의 기초자료로 활용될 수 있을 것으로 판단된다.
