Abstract

Standard production unit system and historical cost data are the most typical data base for calculating budget price in construction. However, these construction cost estimation methods are difficult to calculate proper construction cost because definition, additional allowance or modification criteria is not clear in construction within one day. Therefore, this study identifies problems for standard production unit system and historical cost data and suggests the improvements for them. For the objectives, this study analyzes frequency after implementing survey for 44 specialty contractors in placing at kyeonggi-province. As the results of the study, labor costs in standard production unit system and equipment costs in historical cost data and in construction of pavement and maintenance by project type was exceeded at most high rate against construction cost estimation methods. Based on this result, standard production unit system and historical cost data need to be modified by three improvements such as classification by project scale. These will be baseline data for improvement of construction cost estimation methods for less than one day workload.

표준품셈과 실적공사비 적산방식은 건설공사의 예정가격을 산정하는 가장 대표적인 기준자료이다. 하지만 이러한 공사비 산정방식은 1일 작업량 미만의 작업에서 정의, 할증 또는 보정기준 등이 명확하지 않아 적정 공사비의 산정이 어려운 실정이다. 따라서 본 연구는 1일 작업량 미만의 작업에서 표준품셈과 실적공사비의 문제점을 파악하고 이에 대한 개선방안을 제시하고자 한다. 이를 위해 본 연구에서는 경기도내 44개의 전문건설업체에 대하여 설문조사를 실시하여 빈도분석을 하였다. 본 연구를 통하여 표준품셈에서는 인건비, 실적공사비에서는 장비비, 공종별로는 도로포장 및 유지공사의 장비비가 각각 가장 높은 비율로 초과되었다는 결과를 도출하였다. 결과를 바탕으로 표준품셈과 실적공사비는 공사의 규모에 따른 구분 등 각각 3가지의 개선이 필요하다. 본 연구의 결과는 1일 작업량 미만의 작업에서 공사비 산정 제도의 개선을 위한 기초자료로 활용될 수 있을 것이다.
