摘要

Project overruns are still the most common problem in the world, despite the availability of project monitoring tools like Earned Value Management which is proved to the effective monitoring tool which combines three aspects like scope, time and cost at once. Construction project included high risk activity in which must be managed well in all stages, in order to evade project overruns. The study aimed at assessing the use of Earned Value Management in time and cost management for construction projects in Tanzania. However, there are few of researches that discussed Earned Value Management practices in Tanzanian construction industry. Therefore, it was found that there was inadequacy of documented Earned Value Management implementation in Tanzanian construction projects. The feedback from construction experts was obtained through questionnaires. About 161 questionnaires survey were distributed to the contractor’s organizations (Class I and Class II). Out of the 161 distributed questionnaires, only 102 were returned. The data were analysed by using SPSS 20, Microsoft Excel and then ranked conferring to (M.S) mean score for contractor. The general response from respondents were analysed, high scored factors were discussed. All work scope was planned for the project to completion applied in construction projects, all work scope was broken into finite pieces and assigned to either individual or organisation to control, Issuance of Payment is based on work performed and Actual cost incurred were used in measuring work value accomplished; were identified as the most parts of Earned Value Management applied in Tanzanian construction projects, due to having a mean score above 4.00. The study recognised that key players in Tanzania construction industry applied some parts of Earned Value Management concepts during construction projects.
