    Analysis of cost management of engineering services for large projects in Tanzania.
    (University of Dar es Salaam, 2006) Athumani, Rehema A.
    Most of large projects are not completed within the tolerable range of project budgeted cost. This study assessed the cost management of large projects and effect of donor funding with the objective of establishing the contributory factors of project cost overruns and the root courses of complexities in managing cost. The study has attempted to make comparison on the use of existing techniques and suggested for adoption of improved ones. The study was performed by making use of questionnaires and interviewing project managers, engineers and technicians within TAA as the case study. Twenty-nine respondents were given questionnaires out of 34-targeted numbers and 25 responded. Furthermore, a total of 15 respondents were interviewed from six construction contractors and four consultants. The study revealed that, a performance measurement technique is not effective for cost management, unless it gives the measurement of the actual progress against the predetermined schedule and the actual cost against the budget estimate. The research established that 75% of schedule and budgetary problems arise out of donor conditionality. The study also revealed that although the application of project management software has a potential for performance improvement, only 40% of the projects utilize them. The research concludes that, donor conditions and time taken between project appraisal and effective implementation highly contributes to project cost overruns. It is recommended that there is a need to review procurement procedures, minimize time lag as well as use computers software in project management, particularly in cost management.
