ANALYSIS OF PRODUCTION RATES AND SCHEDULE DELAYS IN LINEAR ROAD CONSTRUCTION PROJECTS: A CASE STUDY APPROACH

Abstract

Linear construction projects such as road infrastructure development are highly sensitive to variations in production rates, which significantly influence project duration and scheduling performance. This study presents a detailed case study analysis of production rates and schedule delays in a road construction project. The research investigates the variability in activity productivity and its impact on overall project timelines.

Field data related to key construction activities, including earthwork, subgrade preparation, granular sub-base, and bituminous layers, are analyzed using statistical and comparative methods. The study evaluates planned versus actual production rates and identifies deviations contributing to schedule delays. A simulation-based approach is employed to assess the influence of variability on project duration.

The results indicate that fluctuations in production rates, particularly in critical activities such as pavement layers, significantly affect project completion time. The study highlights the importance of accurate productivity estimation, effective resource planning, and continuous monitoring to minimize delays. The findings provide practical insights for improving scheduling efficiency and project control in linear infrastructure projects.
