Abstract : The study aimed at assessing the impact of Time and cost factors toward the completion of Mbeya city highway road construction. Specifically, the study examined financial cost operational efficiency upon the whole process of supplying materials in road construction, exploring the quality and technical performance of road construction project as well as evaluating the time schedule of material supply for highway road construction. Where by a mixed approach was used on a sample size of 100 respondents using contractors, consultants, and beneficiaries as target population, moreover, the researcher used desk study and the questionnaire survey to get data about the impact of time and cost factors. Data was analyzed using statistical package for social science (SPSS), Excel and Relative importance index (RII. The relative importance index was useful for calculating the impact of time and cost factors by ranking different factors; ), The main factor leading to delay upon the accomplishment of the road construction project in Mbeya was identified as inadequate budget which ensure insufficient provision of fund upon project , and discussion was made in relation to other supporting factors like poor project design, poor management process and political interference s. In the end of study recommendation and conclusion was made following various policies reinforcement and relation upon different construction project of Tanzania nation.
