Research has found that, there are many factors that impede on successful completion of projects on time, budget, and quality. This study seeked to investigate the effect of Contractor Knowledge and Experience on Cost Estimation in Plant infrastructure Projects in Kenya and analyse its impact. This study reviewed available literature and theories about project cost estimation thus theory of Learning Curve (LC), triple constraint theory, Complexity Theory and S-Curve theory. The descriptive research design was identified as the design of this study. The population of this study was 1000 REL employees and associates working in the area of projects operations and management. The study used a census sampling technique. Primary data was collected using interview and questionnaire and secondary data was collected by reviewing published materials. The data was presented in tables, charts and figures. It was established that contractor knowledge and experience has an adverse effect on cost estimation in plant infrastructure projects. The results should enable planners to take stock of past performance and incorporate lessons learned on future projects planning and implementation.
