Abstract

Construction productivity plays a crucial role in determining the success and efficiency of project implementation. In foundation works, particularly bored pile installations, productivity is often affected by various technical and environmental factors. This study focuses on analyzing the productivity of bored pile foundation work on the Hotel X project in Lumajang City and identifying the dominant factors that hinder performance. The research employed a mixed-method approach combining quantitative productivity analysis with qualitative field observations and interviews. Productivity data were calculated using the Unit Completed method, while statistical testing was conducted using SPSS software to determine the correlation between influencing variables such as materials, equipment, labor, environment, and management. The analysis revealed that for bored piles with diameters of 600 mm and 500 mm at depths ranging from 5 to 18 meters, the average productivity rate was 0.86 meters per hour per unit during a 37-day observation period (totaling 1,713 working hours). Material factors contributed most significantly to productivity losses, accounting for 39.66% of total lost work hours (165.53 hours out of 417.35 hours), followed by environmental, equipment, labor, and management factors. The findings demonstrate that inadequate material logistics and unstable soil conditions substantially reduce project efficiency. In conclusion, effective management of these key factors is essential to improve productivity performance in bored pile foundation work on construction projects.

Abstract

In construction project management, cost and time are two crucial, interconnected elements. Delays in project completion and cost increases are common issues that are often encountered. This research aimed to evaluate and control the cost and time of the Arjuno Agro Techno Park development project using the Earned Value Management (EVM) method. EVM is an integrated method that combines scope, cost, and time measurements to objectively assess project performance. The primary focus of this study was to identify cost and time deviations from the initial plan and determine the project's performance status at specific periods.The approach applied in this research was quantitative, involving data collection related to the Budget Estimate Plan, project schedule, and actual progress reports from the Arjuno Agro Techno Park project. The data was analyzed using EVM indicators such as, BCWS, ACWP, SV, CV, SPI, CPI, ETC, EAC, EAS, and ETS. The research findings indicated that the project experienced schedule delays, evidenced by an (SPI < 1) from the 7th to the 21st week. Nevertheless, the project was successfully completed in the 22nd week, which was initially targeted for completion in the 21st week. However, the project's completion cost tended to be more efficient compared to the initial contract value, as indicated by a (CPI > 1).
