Abstract

Project management is crucial to the success of infrastructure development, including healthcare facility projects such as community health centers. This study aims to analyze time and cost management in a community health center construction project in Kakaskasen Village, Tomohon City. The research method used earned value management (EVM) analysis to evaluate project performance, specifically schedule and cost. The results showed that the project experienced significant time and cost deviations in several construction projects. The schedule performance index was below 1, indicating project delays, while the cost performance index was also below 1, indicating cost overruns. Factors contributing to the delays included poor coordination with relevant parties, delays in material procurement, and unfavorable weather conditions. Proposed recommendations include improving initial planning, strengthening risk management, and more intensive progress monitoring to ensure project completion meets established targets. This research is expected to contribute to improving the management of similar projects.

Abstract

Material is one of the most important components in construction projects because it serves as the primary element of building structures and significantly influences project costs. Ineffective material management can result in construction material waste, leading to increased costs and reduced resource efficiency. This study aims to identify the dominant waste-generating materials and analyze the factors causing material waste in the Hermana Lembean General Hospital construction project. Data were collected from as-built drawings, material logistics reports, and field interviews. The Pareto method was used to determine the dominant waste materials, while the Fishbone Diagram method was applied to identify the root causes of material waste. The results showed that the total construction material waste generated during the project was 3,951.784 units. Pareto analysis indicated that reinforcing steel (53.21%), wall ceramic 60 × 60 cm (11.38%), lightweight brick (8.49%), and floor ceramic 60 × 60 cm (7.49%) were the dominant waste materials, accounting for more than 80% of the total waste volume. Fishbone Diagram analysis revealed that material waste was mainly caused by machine, method, material, manpower, and measurement factors. These findings can be used to improve material management and reduce waste in future construction projects.
