Efficiency of Material Procurement, Time, and Cost Control in the Canopy Construction Project at RSKD Duren Sawit

Abstract

Material procurement plays a critical role in determining the cost and schedule performance of hospital-based construction projects, where limited storage space and active medical operations constrain logistics. This study evaluates the efficiency of the material procurement system and its relationship with cost and time performance in the canopy construction project at RSKD Duren Sawit, East Jakarta. A descriptive quantitative case study approach was applied, combining field observation, structured interviews, and secondary project documents (purchase orders, bill of quantity, budget plan, and weekly progress reports). Cost and schedule performance were analyzed using Earned Value Analysis (EVA), while the Critical Path Method (CPM) was used to identify the activities controlling total project duration. The results show a Cost Performance Index (CPI) of 1.316 and a Schedule Performance Index (SPI) of 1.071 at week 10, indicating that the project was completed under budget and ahead of schedule, with an estimated cost saving of approximately IDR 461 million against the total budget. CPM analysis identified the motorcycle parking canopy works as the critical path, with zero float, while the ICU canopy works and K3 (occupational safety) activities had considerable float (30-75 days). Procurement efficiency was found to be influenced by accurate material volume planning, effective vendor price negotiation, Just-in-Time (JIT) delivery scheduling adapted to hospital operating hours, and strict incoming-material quality control. These findings provide a practical reference for managing material procurement in construction projects located within active healthcare facilities.
