Identifying factors affecting schedule and cost performance on building project

Abstract

The project cost and schedule are two major factors which contribute to the project performance. Therefore, it is important to identify factors that affect project cost and schedule performance, which will, in turn, affect the whole project performance. Previous studies have listed many factors have a large impact on time and cost performance, however the discussion related to the relationship between influencing factors and performance parameters is still limited. This research identified and refined 15 influencing factors through literature review. Those factors were grouped into 3 group factors: resource, environmental and management. Then, further literature review further was conducted to determine the relationships between influencing factors with project time and cost performance. The study focuses on factors influencing project cost and time performance based on the physical progress and actual cost. The result shows that resource group is the most variable influencing physical progress, direct cost and indirect cost. While environment and management group influencing physical progress and indirect cost.
