Abstract In recent years, mechanized construction has become commonplace due to increases in the scale and complexity of construction, and construction machinery is a major factor in successful construction. However, even though the proportion of construction machinery is increasing, analysis of the work capacity of construction machinery is inadequate. In addition, since the standards for all construction machines are currently not defined in quantity-per-unit, the construction period is arbitrarily applied according to the operator at the time of the construction plan. As a result, the construction period of the actual construction is insufficient, and rushed work or construction delays occur. Therefore, in this study, in order to calculate the construction period of the piling work of the pile driver used in the PRD method more accurately than the existing method, the formula for calculating the time required for the piling work of the pile driver was established by collecting piling time data from the daily task reports through the field survey. If the precise construction period of piling work is estimated based on the results of this study, it will be possible to prevent the rushed work and construction delays that occur due to the short construction period. 근래에 공사의 대형화, 복잡화 등으로 인해 기계화시공은 보편화되었으며, 건설기계는 성공적인 시공을 위한 주요소이다. 그러나 건설기계가 차지하는 비중이 높아지고 있음에도 불고하고 건설기계의 작업능력에 대한 분석은 미미한 실정이다. 또한 현재 품셈에서 모든 건설기계에 대한 기준이 정의되어 있지 않음으로 인해 시공계획 시 작업자에 따라 공사기간을 자의적으로 적용하고 있어 실제 시공 간 공사기간이 부족하여 돌관작업이나 공기지연이 발생된다. 따라서 본 연구에서는 PRD공법에서 사용되는 항타기의 천공작업 공사기간을 기존 방법보다 정확하게 산출할 수 있도록 작업일보를 현장 실사를 통해 천공시간 데이터를 수집하여 항타기의 천공 작업 소요시간을 산정하는 식을 정립하였다. 본 연구 결과를 바탕으로 천공작업의 정확한 공사기간을 산정한다면 공사기간이 부족하여 발생하던 돌관작업이나 공기지연을 방지할 수 있을 것으로 사료된다.
