This thesis analyzes the effect of contract remuneration type, lump sum or cost reimbursable, on various construction project performance factors. While there are many commonly held beliefs concerning contract remuneration effect on construction project performance factors, there are few studies that specifically investigate this issue. The Construction Industry Institute's Benchmarking and Metrics database contains data on 395 construction projects worth nearly 21 billion dollars and represents an excellent opportunity to conduct this research investigation. The project performance factors to be analyzed include cost growth, schedule growth, design-construction overlap on design-build projects, changes and safety. Conclusions and recommendations are presented based on the results of the analysis.
