Abstract

Inaccurate pre-tender cost estimates do not only contribute to cost overruns but also results in failure to implement viable projects. This study investigated factors that influence the accuracy of pre-tender cost estimates in the Zambian roads sector. The methodology adopted was a mixed method which included the use of both qualitative and quantitative approaches. The study established that the most severe accuracy-influencing factors for pre-tender cost estimates were completeness of the project information, which had SI of 87%. Clarity and details of the drawing as well as the specification having SI 85% was ranked second. The study therefore, recommends that, more time should be allocated to the design team to comprehensive prepare drawings and coordinate various players such as mechanical and civil consultants before the pre-tender estimate can be sought.
