Abstract

In construction management, the smallest measure of labor and equipment output capacity that is considered effective for meeting project objectives within a specified timeframe is known as minimum production. If the actual production level falls below the minimum production limit, work efficiency will decrease, directly impacting project completion delays. Project delays are a serious challenge that often occurs in completing a project. This study aims to determine the minimum labor and equipment production required, the project completion time for each work item, and evaluate the impact of minimum production on project completion time. This study began with the collection of initial data: work volume, labor and equipment coefficients, effective working hours, a tool list, and project documentation in the form of weekly project reports. This study continued with calculating the number of workers, calculating production, calculating minimum production, calculating the completion time for labor, equipment, and labor and equipment, establishing relationships between work items, creating a network diagram for labor, equipment, and labor and equipment, and evaluating the impact of minimum production on project completion time. The results of this study indicate that the impact of minimum production on labor and equipment is caused by differences in production and completion time. A total of 12 work items were analyzed, with 11 other work items having the same coefficient, production, and completion time. However, there was one work item with different coefficients, production, and completion time: Paving Blocks, where the coefficients for labor (Workers: 2.4746, Craftsmen: 2.4746, and Foremen: 0.4949) and tools (Tamper: 0.2969, 1,000 tools). Production for labor was 28.29 m3/day and production for tools was 23.57 m3/day, with completion times of 68 days for labor and 82 days for tools. This causes the project duration to differ when adding the total completion times of the 12 work items: the project duration for labor was 82 days, the project duration for tools was 96 days, and the project duration for labor and tools was 96 days.
