Abstract

This study investigates the impact of design changes on time and cost control in the Namrole-Leksula I road project in Maluku Province. The research aims to identify key factors influencing design modifications and to develop strategies for managing their effects on project scheduling and budgeting. A quantitative-descriptive approach was employed, utilizing direct data collection, field technical surveys, and stakeholder interviews. The population comprises project execution personnel and government officials, with purposive sampling of 20 experts. Data were analyzed using Critical Path Method (CPM) tools and volume comparison techniques for work items. The results indicate that unstable subgrade soil, road width variability, and damaged structures significantly affected work volume and necessitated contract amendments without changing total project duration or budget. The study concludes that integrating CPM with field assessments provides effective management for mitigating risks from mid-project design changes while maintaining quality and timeline compliance. Future research should explore broader contexts and advanced monitoring tools.Abstract
